    Good evening,

    My husband has been using Fenben labs product for almost two years for stage 4 prostate cancer with good results and no adverse effects.
    In November he had what is believed to have been gastroparesis due to long term GLP1 use for his DM type 2.
    He didn’t eat for nearly three months due to the pain and developed ascites thought to be due to albumin leakage secondary to prolonged malnutrition.
    A couple of weeks ago, his renal function was compromised also due to the malnutrition as everything else was ruled out. His liver function was never altered.
    The fluid was removed via paracentesis and his renal function began improving as soon as albumin support was started.
    Of course, the doctors told us that the fenben use was contributory to the situation and discouraged use.
    I’ve never noted any study that supports impaired renal function while using fenben at recommended doses, and certainly not when liver function isn’t at all altered.

    Just wanted to double check as to whether this should be a concern as I believe he needs it.

    Thanks very much,
    Meri

      Dear Meri,
      Thank you for sharing your husband’s situation so clearly. We understand how concerning this period must have been, especially given the prolonged malnutrition and subsequent complications.
      Based on available data and extensive community experience, fenbendazole at commonly used supplemental doses has not been associated with direct renal toxicity. There is no established evidence showing that it impairs kidney function, particularly in cases where liver function remains normal. Reported side effects at standard doses are generally mild and most often gastrointestinal in nature.
      Severe malnutrition, hypoalbuminemia, fluid shifts, and ascites are all well-recognized factors that can independently compromise renal function. The improvement observed after albumin support and paracentesis is consistent with renal impairment secondary to nutritional and fluid imbalance rather than a direct toxic effect.
      While it is always appropriate to reassess all compounds during periods of acute instability, current evidence does not support fenbendazole as a known cause of renal dysfunction at recommended dosing levels.
      We hope this helps provide reassurance. Please feel free to contact us if you need any additional information.

        Hi! I’m starting a 3-month course of 4mg of daily ivermectin for Babesia and parasite treatment. I’m interested in layering Fenbendazole for additional Lyme co-infection/parasite/CIRS treatment. Would it make sense to do a 10-week course of 222mg Fenbendazole 3 days on and 4 days off, then considering another 10-week pulsing schedule after a 10-week break? Should my husband and dogs follow the parasite schedule of 5 days on, 3 weeks off as more of a preventative measure? Or does following the same schedule as me make sense if my dogs or asymptomatic but eat raw diet and my husband has milder symptoms but no Lyme/coinfection diagnosis? Thank you so much for all your help!

        1. Fenbendazole.org

          Hello Wesley,
          It can be reasonable to combine fenbendazole with ivermectin for antiparasitic purposes, and both agents are commonly used against certain parasites; however, Lyme disease is generally treated with specific, targeted medications, and prioritizing those established options is typically more appropriate than relying on fenbendazole or ivermectin for Lyme-directed treatment.
          For dosing and schedules, we recommend using our dosage calculator at https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/ where you can find the necessary information, suggested use schedules, and dose guidance for both humans and animals. A 10-week pulsing schedule is not commonly used, and we do not have substantial information to confidently comment on that specific regimen, which is why we direct users to the dosage calculator and its established protocols.
          Your husband and dogs can also follow an antiparasitic protocol from the dosage calculator, including preventive-style schedules when appropriate. For prophylactic parasite support, a commonly used approach is to run a fenbendazole parasite protocol every 6 months, structured as 5 days of use, then repeating the same 5-day course again after 3 weeks, and then waiting 6 months before repeating the 2-cycle sequence again.

    I have a large fibroid, would the normal parasite treatment be affective or is that under cancer protocol? also, is it important to take a binder when taking Fenbendazole?

    1. Fenbendazole.org

      Hello Jo,
      Thank you for your question.
      Uterine fibroids are benign growths and are not classified as cancer. For this reason, they are generally approached differently from oncology-focused use. Some people choose to follow a standard antiparasitic-style dosing rather than a cancer-oriented protocol, although there is no single mandatory approach. On our website, the dosage calculator allows you to select the intended use of fenbendazole, including a general antiparasitic option, which can help guide dosing based on individual goals.
      The use of binders is not required when taking fenbendazole. Binders are optional and are typically used to bind and eliminate certain substances from the digestive tract. Because fenbendazole needs to be absorbed to exert its effects, binders should not be taken at the same time, and many people choose not to use them at all.
      We hope this helps clarify your questions.

    Hi Zee here, My dad was ….AI summary:

    Diagnosis:
    Diagnosed in Aug-2024 with a low rectal adenocarcinoma, staged cT3 cN1c M0, moderately differentiated, with a threatened circumferential resection margin and tumour located ~2–3 cm above the anorectal junction. The tumour is mismatch-repair-proficient (pMMR), microsatellite-stable (MSS), consistent with the conventional chromosomal-instability (CIN) subtype. Disease was non-metastatic but locally advanced. Immunotherapy was discussed and not indicated due to intact mismatch-repair proteins. The BNT122 vaccine trial was also reviewed, but eligibility criteria were not met.

    23-Nov-2025 CT Scan:
    The scans from November and December 2025 show that the cancer has grown back locally near the rectum but has not spread elsewhere in the body. A CT scan in November 2025 showed a left-sided mass next to the rectum measuring about 3.3 cm, which had increased in size compared to earlier scans. This mass appeared partly dead inside (necrotic) and was stuck to the rectum and surrounding tissue, but there were no signs of spread to the lungs, liver, or other organs.

    16-Dec-2025 MRI Scan:
    An MRI scan in December 2025 confirmed that the mass had grown slightly larger to about 3.5 cm and was more firmly attached to the rectal wall, although it had not grown into the inside of the bowel. Importantly, there was no spread to nearby side-wall lymph nodes, major blood vessels, or bones, meaning the problem remains localized to the rectal area, but is clearly progressing and needs active treatment.

    Currnet Protocol:
    Started with Feb-2025
    – Low Carb Diet (not entirely Keto)
    – No Sugar

    Added Jul-2025
    – Vitamin D3 2x/week in the morning
    – Iron 1x/week in the morning

    Added Oct-2025
    – Magnesium Glycinate 3-in-1 1800mg 1x/day evening

    Added Dec-2025
    – FenBen 222mg 1x/day after meal 5-Day On 2-Day Off
    – Curcumin 150mg 2x/day after meals Daily

    Along with usual,
    – Thyroid medicine
    – High BP medicine

    Concern:
    I’m really concerned about our last meeting in Jan-2026 with the Oncologist.
    – The only option give was Surgery
    – because Immunother will not work
    – Radiotherapy the body can’t take it any more
    – And lastly Chemetherapy 75% that down the line we would need surgery
    – Proton Beam Therapy is old school
    – Oxygen Therapy is no evidence etc

    Query:
    So Is the FenBen protocol that my dad folowing OK? I’m concerned that his tumor or mass has grown?
    Please share your thoughts.

    1. Fenbendazole.org

      Dear Zee,
      Thank you for sharing your father’s detailed history. We understand your concern, especially in light of the recent imaging.
      Based on what you described, the disease remains locally confined, which is an important point. The fenbendazole dose and schedule your father is using fall within ranges commonly used in supportive, metabolic-oriented approaches. Fenbendazole is generally not viewed as a fast-acting tumour-shrinking agent. Instead, it is often used with the aim of influencing cellular stress, metabolism, and longer-term tumour behaviour. For this reason, short-term changes in size on imaging do not necessarily mean the protocol is ineffective.
      Local regrowth can occur for many reasons, and responses to supportive protocols are often gradual and variable. Many people in similar situations focus on stability, slowed progression, or maintaining quality of life rather than expecting immediate radiological improvement.
      From the information provided, there is nothing inherently inappropriate about the current fenbendazole schedule itself. Ongoing observation, consistency, and a broader supportive strategy are usually key.
      You are welcome to reach out again if you have further questions or would like additional educational resources.

    I’ve been on many treatments over the past 5 years for stage 4 metastasized neuro-endocrine tumors which have moved initially to my liver and now to lymphatic system and bones. I was released on hospice from the hospital a month ago. from my treatments i now have an issue with my blood pressure, where it drops down as low as 70/50 with a pulse up to 130. Ironically cancer gave me high blood pressure so i’m actually taking medication to lower my blood pressure and to raise my blood pressure. ideally my blood pressure is 180/85 with medication. This is the reason my treatment was stopped. My husband is worried that fenbendazole could cause problems with my blood pressure or my liver; my liver is covered in tumors and has been since I was diagnosed, Also the only fenbendazole I can find locally is safe-guard goat dewormer liquid. How do I figure out dosing on this? Should I start at a lower dose than 222? Should I do less days than 6 to start?

    1. Fenbendazole.org

      Hello Margaret,
      Thank you for sharing this, and we understand why both you and your husband are concerned given your blood pressure instability and extensive liver involvement.
      Fenbendazole is not known to directly lower or raise blood pressure, and there is no evidence that it acutely affects heart rate or vascular tone. That said, in someone with labile blood pressure and significant liver tumor burden, a cautious and conservative approach is appropriate. The concern here is less about blood pressure itself and more about overall tolerance and liver stress.
      Regarding the product you mentioned, liquid livestock dewormers can make accurate dosing difficult, which increases the risk of under- or overdosing. For this reason, we strongly recommend reviewing the trusted suppliers list on our website, where dosing is clearer and more consistent:
      https://www.fenbendazole.org/suppliers/
      In terms of how to start, beginning lower and slower makes sense in your situation. A commonly used cautious starting approach is 222 mg, 4 days per week, taken with food. If this is well tolerated and your liver enzymes and basic labs remain stable, some people then move to a 6 days on, 1 day off schedule. There is no need to rush this step.
      Because your liver is already heavily involved, it is especially important to monitor how you feel, watch for worsening fatigue, nausea, abdominal discomfort, or changes in mental clarity, and to check liver enzymes when possible. If anything feels off, pausing and reassessing is reasonable.

    I’m planning to start Fenbendazole for my 20 lb Dachshund who has TCC and some kidney compromise—should I use a lower dose because of her kidneys? We’re also planning to add a chemo pill (either Palladia or lapatinib, three days a week), but should I wait a week or two before starting it so we can tell which medication is causing any side effects? Has anyone had experience giving Fenbendazole and one of these chemo pills together?

    1. Fenbendazole.org

      Hello Joanne,
      Thank you for your questions. You are approaching this very thoughtfully, especially given your dog’s kidney compromise.
      With kidney issues present, starting fenbendazole at the lower end of the commonly used veterinary dose range is a cautious and reasonable approach. Close observation of appetite, energy, hydration, urination, and kidney values is important before considering any increase.
      When adding a chemotherapy drug such as Palladia or lapatinib, it is generally best not to start both treatments at the same time. Waiting one to two weeks between introducing fenbendazole and the chemo medication makes it much easier to identify the source of any side effects.
      Some owners do use fenbendazole alongside targeted chemo drugs, but tolerance can vary, particularly with kidney compromise. Introducing treatments gradually and monitoring labs with your veterinarian is the safest way to proceed.

    Hello – what about the piperine in curcumin supplements? Wouldn’t that cause the fenbendazole to uptake to dangerous levels or increase the dosage about what is intended?

    1. Fenbendazole.org

      Hello, Ciaran.
      Good question – this comes up a lot.
      Piperine works by inhibiting certain liver enzymes (mainly CYP3A4 and P-glycoprotein). That can increase the bioavailability of drugs and supplements that are rapidly broken down or pumped out by the gut and liver.
      Fenbendazole already has relatively low oral bioavailability and is metabolized into active metabolites (like oxfendazole). Even if piperine increases absorption somewhat, we are not talking about a massive or unpredictable spike at standard fenbendazole dosing used by most people.
      The concern is theoretical rather than evidence-based at this point.
      I you are still concerned – avoid taking high-dose piperine (for example 10–20 mg) at the exact same time as fenbendazole. If your curcumin contains piperine, separate dosing by a few hours.

      1. Jen

        Hello, while taking Fenbendazole do you need a binder? I’ve been reading comments on certain sites and I see people saying yes and others not even mentioning needing a binder. So, I’m confused as to what I should do. This would be for the 222mg dose. Thank you

        1. Fenbendazole.org

          Dear Jen,
          Thank you for your question.
          A binder is not required when taking fenbendazole, including at a 222 mg dose. Many people use fenbendazole without any binders and do not experience issues. The idea of a binder comes from broader detox or supplement practices, not from any specific requirement related to fenbendazole itself.
          Some individuals choose to use binders such as activated charcoal or similar products as a personal preference, particularly if they feel sensitive or experience gastrointestinal discomfort. However, this is optional rather than necessary. If a binder is used, it should be taken well separated from fenbendazole and other medications or supplements so it does not interfere with absorption.
          In summary, fenbendazole can be taken on its own with food, and a binder is not essential. Whether to use one is an individual choice rather than a requirement.

    I have stage three kidney disease, but have no symptoms and am not on any medication. I have been diagnosed with prostate cancer, with a 3.4 Gleason score. My question is, should I start with 110mg a day for 3 days on and 4 off initially and work upto 6 days on 1 day off?
    Any advice please? Many thanks in advance ☺️

    1. Fenbendazole.org

      Hello Scott,
      Thank you for your question.
      Given that you have stage three chronic kidney disease, a more cautious and gradual approach is sensible. Starting at a lower dose and with fewer consecutive days, such as 110 mg with a shorter on/off cycle, allows you to assess tolerance before increasing exposure. This is especially important even in the absence of symptoms, as reduced kidney function can affect how the body handles metabolic stress over time.
      Many people do gradually work toward a more standard schedule, such as 5-6 days on with 1-2 days off, but this is typically done only if the lower dose and shorter cycle are well tolerated and laboratory values remain stable. Using a weight-based dosage guide, such as the calculator on our website, can help frame the upper range, but in your case remaining at the lower end initially is prudent.
      Regular monitoring of kidney function, hydration status, and overall tolerance is important before making any increases. Adjustments are best made slowly and guided by objective laboratory results rather than a fixed timetable.

        I had an MRI that confirmed I have a golfball sized tumor on my brainstem at the base of the brain. The neuro-surgeon states he can only get 1/2 of the tumor removed due to the risks of injuring the brainstem. He also stated it is “non-cancerous” but yet no one has done a biopsy because of its location and not sure how the doctor can claim that he knows that’s it’s not cancer. Radiation/Chemo is not an option because it could sever the brainstem. A friend of mine told me about Fenben because it got rid of his nasal cavity cancer. I’ve purchased Fenben and started taking it on Tuesday. My question is: by taking Fenben and Extreme Curcumin, can the golfball tumor shrink/disappear? Symptoms before taking Fenben: dizzy all the time where I can’t drive and difficult to walk, difficulty swallowing due to where tumor is, skin sensation (tingles, like asleep), constipated and difficulty #1. I understand Fenben is a marathon not a sprint but am I in the right marathon? Much appreciated.

        1. Fenbendazole.org

          Hello Jen,
          Thank you for sharing this, and we understand how difficult and unsettling this situation is, especially given the tumor’s location and the limited conventional options available.
          It is reasonable to question the certainty of a “non-cancerous” label without a biopsy, particularly when imaging alone cannot always provide full biological clarity. In situations like this, many people choose a metabolic and repurposed-drug approach because it focuses on influencing cellular behavior and the tumor environment rather than relying on direct cytotoxic treatments.
          Fenbendazole and curcumin are commonly used together for this reason. While no one can promise that a tumor will shrink or disappear, there is a sound rationale for using these compounds to potentially reduce inflammatory signaling, disrupt abnormal cellular processes, and slow further growth over time. As you noted, this approach is best viewed as a marathon rather than a sprint, and meaningful changes, if they occur, are typically gradual and assessed through symptoms and follow-up imaging.
          Some individuals in similar situations also choose to add ivermectin and DCA (Sodium dichloroacetate) to their protocol, as both are discussed for their potential effects on cellular metabolism and mitochondrial function, including in neurologic and brain-related conditions. When added, they are usually introduced cautiously, one at a time, with attention to timing, tolerance, and routine laboratory monitoring.
          Based on your description, you are approaching this thoughtfully and with realistic expectations. Staying consistent, supporting overall metabolic and liver health, and monitoring both symptoms and imaging over time will provide the clearest indication of whether this path is benefiting you.

        Can fenbendazol help for helicobacter

        1. Fenbendazole.org

          Dear Hari,
          Thank you for your question.
          Fenbendazole is an antiparasitic compound and is not known to be effective against Helicobacter pylori. H. pylori is a bacterium, not a parasite, and it requires antibiotic-based treatment (usually a combination of antibiotics plus acid suppression) to be reliably eradicated. There is currently no scientific or clinical evidence showing that fenbendazole can eliminate H. pylori infection.
          For H. pylori, standard medical testing and treatment protocols remain the most effective approach. Fenbendazole is generally discussed in the context of parasitic infections and repurposed metabolic approaches in cancer, but it should not be considered a substitute for evidence-based H. pylori therapy.

  8. Ember

    Hello,
    I’ve just undergone a hysterectomy and removal of both ovaries due to stage 3 ovarian cancer. Will be taking the recommended amount of Fenben (222mg) for 6 days, skip on the seventh day, repeat weekly. Will also be taking 500 mg of curcumin and 250 mg of milk thistle twice a day with food.
    Have also got ivermectin. How could I incorporate 12mg tablets into this protocol?
    I would also like to incorporate vitamin D3+K2 into the protocol but am unsure of how often and at what strength to take it?

    1. Fenbendazole.org

      Hello Ember,
      Thank you for sharing this, and we acknowledge the significant step you have just been through with surgery.
      Your fenbendazole schedule of 222 mg daily for 6 days with 1 day off is a commonly used approach, and combining it with curcumin 500 mg twice daily and milk thistle 250 mg twice daily with food is reasonable for ongoing liver support.
      Regarding ivermectin (12 mg tablets), it is frequently used alongside fenbendazole within repurposed-drug protocols. It is commonly taken on the same days as fenbendazole, with timing adjusted to absorption. Ivermectin is usually taken on an empty stomach, while fenbendazole is taken with food, often a meal containing some fat. Dosing is typically weight-based, around 0.2 mg per kg, with many individuals using it once daily on fenbendazole days, provided it is well tolerated and liver function is monitored.
      For vitamin D3 with K2, dosing is best guided by laboratory values. In the absence of elevated calcium, a commonly used starting range is vitamin D3 1,000 to 2,000 IU daily combined with vitamin K2 (MK-7) 90 to 120 micrograms daily. Periodic monitoring of serum calcium and 25-hydroxyvitamin D is advisable.
      Gradual introduction and routine laboratory monitoring, particularly liver enzymes and calcium levels, allow the protocol to be adjusted safely based on objective data.

    Can this be taken with ivermectin if someone is on aspirin for blood thining purposes?

    1. Fenbendazole.org

      Dear Emma,
      Thank you for your question.
      There is no well-documented direct interaction between fenbendazole and ivermectin, and neither compound is known to have a clinically significant blood-thinning effect. Low-dose aspirin acts through platelet inhibition, which is a different mechanism and does not directly overlap with the known pharmacology of fenbendazole or ivermectin. Based on available data, there is no clear scientific evidence suggesting that combining fenbendazole and ivermectin with aspirin inherently increases bleeding risk.
      That said, because aspirin does affect platelet function and because controlled studies on these combinations are limited, it is prudent to monitor for unusual bruising, bleeding, or changes in laboratory values and to proceed cautiously, especially in older individuals or those with additional medical conditions.

  10. Robin

    Why is the dosing for dogs much lower for cancer than it is for parasites? I want to make sure I am dosing my dog correctly who has a tumor on her liver. She is 75 lbs and the calculator says for cancer dose of 444 mg, is this correct? Some websites say 23 mg per pound of body wight which is 1725mg and this website says only 444. I just want to make sure i am dosing her correctly so she has a fighting chance against the cancer.

    1. Fenbendazole.org

      Hello, Robin. A great question.
      The dose of parasites is high, but it is used for a shorter period. This is a more aggressive form, which allows you to get rid of parasites and stop taking it until the next prophylactic deworming.
      For the treatment of cancer or tumors, a milder dose is used, but it is usually used for a much longer period. In this way, the effectiveness is still evident, but the body (mainly the liver) is not severely and quickly exhausted.

  11. LL

    Hi, I am taking – since 2 weeks now – Fenbendazole 1500 mg/day – 6 days, 1 day off + Ivermectin 48 mg 7/7 days.
    Having intestine problem..as light diarhee (third day today).
    I stop using both med and when I will restart, I will begin slowly.
    Should I take Fenben 4 days on/3 days off instead of 6 days in a row?
    Thanks a lot! 🙂
    LL

    1. Fenbendazole.org

      Hello, and thank you for a question.
      Yes, we would suggest starting at 4 days on/ 3 days off and increase frequency of use only when you see that there is no side effects showing. Also we would suggest to start at a lower dose and also ram it up only when you see you have no harsh side effects. A good idea is to monitor your liver enzyme levels also. Do not overlook supplements for liver health, like milk thistle, alpha lypoic acid, curcumin.
      The last thing, you may be sensitive to only one of agents (fenbendazole or ivermectin). From what we have gathered, more people are sensitive to ivermectin and tolerate fenbendazole a bit easier.

    Really stupid question, do I just buy dog dewormer to use for my recently diagnosed colon cancer??

    1. Fenbendazole.org

      Hello Lynne,
      Fenbendazole is the same active molecule regardless of the product category. Our supplier list includes both veterinary deworming products, including dog dewormers, and pure laboratory-grade fenbendazole options.
      You do not need to worry about whether a product is labeled for animals or humans – what matters is that fenbendazole is the only active ingredient and that dosing can be measured precisely.
      If you are exploring fenbendazole and want clear, transparent, side-by-side options, we recommend choosing directly from our curated supplier list, which contains both pure fenbendazole and dog deworming products for informed comparison.

  14. Maggie

    Hello,

    My father was recently diagnosed with Stage 4 prostate cancer with spread to lymph nodes and bones. What would be the recommended dosage? Your calculator states 444mg, but is that too much?

    What else would you take it with?

    Can you also recommend where I can purchase ivermectin in the US?

    Thanks!

    1. Fenbendazole.org

      Hello Maggie,
      For your father’s weight, the calculator is correct in showing 444 mg – it is not “too much” when the weight input matches that dose. The dose is weight-specific, and the calculator adjusts appropriately. If you scroll down below the dose output, you will also see additional information about supportive supplements and cofactors that many people add alongside fenbendazole for metabolic and tolerability support.
      Regarding ivermectin, we are a fenbendazole information page and do not provide guidance on ivermectin sourcing or dosing. For that, you would want to consult other resources that specialize in ivermectin protocols or reach out to a pharmacy or clinician who can advise on legal and safe options in the United States.
      You may also consider researching Sodium Dichloroacetate (DCA) as a complementary metabolic support compound. DCA targets mitochondrial metabolism and can help shift cancer cell energy pathways, which may provide a different angle of metabolic stress on tumors when combined with other strategies. Many patients explore it as part of a broader metabolic protocol, but as with all off-label approaches, tolerance, monitoring, and timing relative to overall health are important considerations.

    So have a question. I have not been to the doc but I have had IBSD for many years. I just in the past year and especially the last 6 months I have had vast changes in my bowels with some pain and bloating. I am not really into getting a colonoscopy but know from when I had it done almost 20 yrs ago I am prone to polyps. So I just thought I would do the cancer regimen for like 3 months and see how I feel. But I have a question about dosage. I see where it says take 222mg a day with Joes protocol. But the calculator for me who is 59yo male at just under 300lbs to take 444mg a day. Which is it? I dont want to overdo it. I am also taking ivermectin liquid at 1ml per 125lbs of body weight. Thanks for any help.

      Hello Jeff,
      For your body weight, 444 mg per day is the correct dose, and the calculator has calculated it accurately. The 222 mg shown in Joe’s protocol is a general example, not a one-size recommendation. Since you want to avoid overdoing it, you can rely on the calculator result – it is specific to you and appropriate for your weight.

    Have had myaisis from phorrid flies from a septic mess in our home. My fiance also has them and animals. We have had them for 8 months and Dr’s only prescribing 13 MG of ivermectin 1 dose.
    Compound pharmacy is giving me ivermectin at 30 MG dose. Using Vaseline to suffocate them but this is a horror story. My dog is also on ivermectin once a month. Just learned about fenbendazole and was told it was necessary to take to eliminate, what protocol should I be using?

    1. Fenbendazole.org

      Hello Chyma,
      We are very sorry to hear about your situation. Myiasis caused by fly larvae can be extremely difficult to manage, especially with ongoing exposure. Ivermectin is commonly used, but dosing may need to be adjusted depending on severity and individual factors. Fenbendazole can be added as part of a comprehensive anti-parasitic approach, as it helps target internal parasites that could complicate recovery. We recommend following the parasite protocol outlined on our website, where you can also use our dosage calculator to determine the appropriate dosing based on weight and treatment plan. It is important to combine systemic therapy with mechanical removal and environmental control, including treatment of any animals in the household, to prevent reinfestation. Always monitor for side effects when using multiple anti-parasitic agents.

      Hi
      Can you use a mebedazole in place of fenbendazole ?

      1. Fenbendazole.org

        Yes mebendazole is also very potent and has almost the same mechanisms of action.

    Does this work if the person has cancer with metastasis?

    1. Fenbendazole.org

      Hello, Florin, and thank you for a question.
      Yes. Fenbendazole can still work in metastatic cancer.
      Its main actions: disrupting cancer cell microtubules, impairing glucose uptake, and stressing cancer metabolism, are not limited to a single tumor site. Metastatic cells rely on the same basic survival mechanisms, so they can also be affected.
      That said, expectations and outcomes are very personal. Some people see stabilization or even remission, while others see slower progression or no clear response. Cancer biology, tumor type, disease burden, combinations used, and overall health all matter. Fenbendazole is not a guarantee, it is a tool, and results vary from person to person.

      1. florin

        It is for my mother, they tried to remove the tumor however it was to big and to many big vanes attached so they didn`t manage to remove it however now she has a bag where all her poo and pee is collected rather then going the normal way. She is very weak, it seems that they found that she has type 2 diabetes and she is anemic as well. she is very weak and not eating much. Everyone are telling us to prepare for the worst but i just can`t just don`t want to give up but at the same time don`t want to make it worst that`s why I ask as this is my last hope. I want to try to give her the 222 mg fenbendazol, in combination with GBD, curcumin and milk thistle. please let me know if this sounds the correct combination? or. could you recommend a different combination?

        1. Fenbendazole.org

          Dear Florin,
          Your mother has been through a lot, but progress does not always need to start with intensity – sometimes it starts with pacing the body into tolerance.
          If you decide to explore fenbendazole, a gentle and commonly used way to introduce it is 111 mg, taken 3 times per week. Many people begin with 3 days per week or 3 doses per week spread across the week to see how the body tolerates it. In your case, starting at 111 mg, 3 times per week is a reasonable low-burden entry point. If she tolerates it well, you can gradually increase exposure – first by expanding to 6 days per week, and only later increasing the dose itself to 222 mg per day if her strength and blood counts remain stable and her body continues to handle it smoothly.
          Curcumin, milk thistle, and gut or glucose-support supplements are generally considered gentle additions, and they align well with a supportive metabolic approach. The key in advanced illness is to watch tolerance, not push it. When the body accepts the plan, that itself is a positive signal.
          Step by step, steadier days, steadier dose – that is how many unexpected turnarounds begin.

  18. Jess

    Hello, I am only just starting on Fenbendazole. I have been reading a fair amount about how it works and am curious about how important it is to dissolve in the body. I have read that the human body will not absorb it if it has not dissolved. So after buying capsules I have also bought the powder. I just did an experiment with olive oil and it did dissolve. Do you think it is a good idea to dissolve it first in something like olive oil? Also could one use Mayo? Or Hummus? If this is a good idea what else would work? Or is it just good enought to take a capsule after a fatty meal? Also curious what kind of fatty meals would qualify?
    Thank you

    1. Fenbendazole.org

      Dear Jess, thank you for your thoughtful question.
      Fenbendazole is a lipophilic compound, meaning it is better absorbed in the presence of dietary fat. It does not need to be fully dissolved before ingestion in order to be effective. What matters most is that it is taken with sufficient fat, which helps improve absorption during digestion.
      Using powder mixed into a fatty medium such as olive oil is one approach some people choose, and your observation that it disperses in oil is expected. That said, it is not required to pre-dissolve fenbendazole. Taking capsules or powder together with, or shortly after, a fatty meal is generally considered sufficient for absorption.
      Foods such as olive oil, avocado, eggs, full-fat yogurt, cheese, nut butters, or meals that naturally contain healthy fats are usually adequate. While mayonnaise can technically work because of its fat content, it is not a particularly healthy food and is generally better avoided if possible. Options like olive oil or whole-food sources of fat are preferable. Hummus can be acceptable, especially if it contains added olive oil, but again it does not need to be complicated.
      In most cases, simplicity works well. Taking a capsule after a normal meal that includes healthy fats is usually enough, without the need for special preparation.
      We hope this helps clarify things as you are getting started, and we wish you the very best moving forward.

    Hello and thank you. I have an 85 lbs German Shepherd mix, with parasites. I have Wormentel 222mg tablets. The calculator above shows 1928 mg. That would be 9 tablets. Is that correct? I see that for a 185 lbs person it is only one 222 mg tablet. Want to be sure. Thank you for this site and your service.

    Mike B

    1. Fenbendazole.org

      Hello Mike,
      The dosage calculator on our website can be used for both humans and animals, and it also adjusts the dose depending on whether the goal is parasite treatment or cancer support. Because you selected dog + parasite treatment, the calculation of 1,928 mg for an 85 lb (≈38.5 kg) dog is correct. That amount corresponds to approximately nine 222 mg tablets.
      The reason this number looks much higher than the single 222 mg tablet often shown for a 185 lb human is due to species-specific metabolism. Dogs metabolize fenbendazole significantly faster, and their gastrointestinal absorption patterns differ from humans. As a result, they require a much higher mg-per-kg dose to achieve the same therapeutic effect. Humans, having slower metabolism and different enzyme activity, need far lower amounts for the same internal exposure.
      So yes – the 1,928 mg dose generated by the calculator is appropriate for your dog’s parasite protocol.

    2. Linda Larouche

      Can I mix Fenbendazole powder in a tomato juice (222 mg), or also in a yogourt?

      1. Fenbendazole.org

        Yes, Linda, you can mix 222 mg of fenbendazole powder with tomato juice or with yogurt.
        Fenbendazole is fat-soluble, so absorption is better when it’s taken with some fat. Yogurt (especially full-fat) usually works better than juice for this reason. If using tomato juice, you can simply add a spoon of oil to improve uptake.

  20. Julia

    Hi! My mother got acute leukemia for 1 year ago (after breast cancer treatment), she had chemotherapy but nothing helps. She had short time of regression, but it starts again and doctors says that nothing helps. She had started taking fenben (222mg) since august 2025 with pause for chemotherapy, but there is no positive results…only worse. She has also started taking ivermectin,curcumin, green tea extract, omega 3, milk thistle. Doest it mean that fenben. doesnt help for her?

    1. Fenbendazole.org

      Hello, Julia.
      It is very hard to judge effectiveness in a case like this. Acute leukemia can be extremely aggressive, and sometimes the disease progresses so quickly that even strong treatments cannot slow it down. It is possible that without fenbendazole her condition might have worsened even faster, but it is also possible that the cancer is simply resistant to everything at this stage. Lack of improvement does not necessarily mean fenbendazole “does not work,” only that the disease may be moving faster than any protocol can control. I am truly sorry your family is going through this.

      1. Tina

        Hi. Thank you for your very informative page. My sister was diagnosed with an aggressive lung cancer. She has declined surgery or chemotherapy. She has a history of COPD and elevated liver enzymes. Would she benefit most from fenbendazole alone or with the addition of ivermectin?
        Also, wondering if there is any interactions with chlorine dioxide protocols?
        Thank you for your consideration.

        1. Fenbendazole.org

          Hello Tina, and thank you for your message. In your sister’s case, it is important to understand that both fenbendazole and ivermectin are metabolized in the liver. When liver enzymes are already elevated, introducing additional compounds that depend on hepatic processing may increase metabolic strain and reduce tolerance. This does not mean they cannot be used, but it does mean they should be approached cautiously, one at a time, and at low starting amounts.
          Many individuals with higher liver enzyme readings choose to include supportive agents such as milk thistle or TUDCA, as both are widely used for maintaining healthy liver function and may help during periods of increased hepatic load. Although evidence is limited, they are generally well tolerated.
          There are no scientific data on the interactions between fenbendazole, ivermectin, and chlorine dioxide, and the oxidative nature of chlorine dioxide makes the combination unpredictable. For safety, it is best not to introduce multiple new agents at once.
          We hope this guidance is helpful, and we wish the very best for your sister.

          1. Kristian

            Can you take fenbendazole while taking klonopin??

          2. Fenbendazole.org

            Hello.
            Yes, you can use it with Klonopin. They do not interact or have any synergistic effect. The only thing you should know is that they are both metabolised in the liver, so take care of your liver health by taking supplements that support it.

    2. LL

      Oh..it’s works! I am able to post!
      Having a question: which one is better Febendazole or Mebendazole? What is the difference?

      Had lung cancer radiotherapy Sept 2023…stage 1….everything was fine till Feb 2024….looks there is something to 1 kidney..biopsy soon…What should I take? Ivermectin (depending of my weight) + Feben 222 mg? Thistle Milk, curcuma….That’s it?

      1. Fenbendazole.org

        Hello and thank you for your message.
        Fenbendazole would be the better choice here because it absorbs more fully and works throughout the body, while Mebendazole mostly stays in the gut. We would recommend starting Fenbendazole 222 mg and see how you feel. If your body handles it well after a week or two, increase it to 444 mg. Use it with food.
        Add Ivermectin according to your weight, taken on an empty stomach. Alongside that, we would include milk thistle, curcumin, vitamin D3 with K2, omega-3 and a low-sugar diet. This keeps the protocol simple, balanced and gentle while you are waiting for the biopsy results.

  21. Jamie

    Hello, thank you for all the help on this thread! My 7 year old Great Pyrenees was just diagnosed with Osteosarcoma of her front leg. I have started her on CBD w/THC and CuraMed (Curcumin Complex). I want to start her on Fenbendazole and Ivermectin as well, but im confused on the schedule and the dosages. The online calculator for the Fenbendazole says to administer her 666mg, she is 100 Pounds how do i convert that to ml to order the correct oral syringes. For the ivermectin, im not sure if i should purchase the sheep, cow or horse and how to dose it and what schedule to use. Do I give the drugs on opposite days or the same days? Please, any help is really greatly appreciated.

    1. Fenbendazole.org

      Hello Jamie,
      Thank you for your message. We understand how confusing dosing can feel in the beginning, and we are glad to clarify the fenbendazole portion for you.
      Our calculator provides the amount in milligrams. If you are using a liquid or paste, you can convert it by checking the concentration on the label. For example, if a product states 100 mg per ml, then 666 mg equals 6.66 ml. The same principle applies to pastes: divide the required milligrams by the mg-per-ml listed on your product to find the correct volume.
      Many individuals who choose to add ivermectin administer it on the same days as fenbendazole but keep a gap between them, such as giving fenbendazole in the morning and ivermectin in the afternoon or evening. We cannot recommend an exact ivermectin dose because we are a fenbendazole information website; however, dog dosing is commonly calculated on a milligram-per-kilogram basis, typically around 0.2 mg/kg.
      Fenbendazole should always be given with food to support better tolerance and steady absorption.

  22. Danie

    Good day
    I have a 12 year old staffie female, she underwent operation in May 2025 to cut out Soft Tissue sarcoma grade II,
    she is around 20kg and I came across fenben just this month so I was thinking of administrating this as a treatment for her to prevent the cancer growth for they said it will come back, so I got a syringe in a paste mix with description Fenbendazole 500mg/ml so is this just enough for 1 or 2 treatments or am i calculating things wrongly?

    1. Fenbendazole.org

      Good day Danie, and thank you for contacting us. For a dog weighing 20 kg, the recommended fenbendazole dosage for cancer support is 444 mg per day. The standard protocol is to give fenbendazole once daily for four consecutive days, followed by three days without fenbendazole, and then repeat this weekly cycle.
      The product you described contains fenbendazole at a concentration of 500 mg per milliliter. This means that slightly under 1 milliliter provides the full daily dose for your dog. Because the concentration is high, a single syringe will only supply a small number of days of treatment before it is finished. This is not a calculation error; it is simply due to the strength of the formulation.
      Please measure each dose carefully and administer fenbendazole with food to support proper absorption. If you have any additional questions about dosing or protocol guidance, you are welcome to reach out to us again.

  23. Brittni

    Hi there, I have been researching heavily as I am wanting to do a heavy metal detox as well as a parasite cleanse. I don’t know if you have any advice for the heavy metal detox. If you do I would be SO appreciative because through my research, I have found a lot of different things but it has ultimately left me feeling unconfident in what to do😔

    As for the parasite cleanse, I typed in my weight for the calculator and everything, I am just curious if I need a binder? Also, any other supplements you would recommend me to take while I’m on it I would be so thankful! I am on daily medications that include Tylenol

    1. Fenbendazole.org

      Hello, Brittni, thank you for a question.
      For heavy metal detox, stick to basics like NAC, milk thistle, chlorella, and stay well-hydrated. No need for extreme cleanses, consistency is key.
      For the parasite cleanse, follow the calculator for fenbendazole dosage. Since fenbendazole is not water-soluble, be sure to take it with fat (like olive oil or coconut oil) for better absorption. A binder isn’t required, but activated charcoal can help, taken a few hours apart.
      For liver support, consider adding vitamin D3, omega-3, magnesium, and milk thistle. If you’re on Tylenol or other meds, keep liver support consistent and start slow.

      1. Justyna

        My dad has stomach cancer with liver damage. He’s lost a lot of weight, now weighing 53 kg. We’re at a loss as to what protocol we should follow and what doses. He’s been on a 444 x 2 dose since early November. Please help and point me in the right direction.

        1. Fenbendazole.org

          Dear Justyna,
          For your father’s current weight, the dose he is taking may be too high. At 53 kg, a more appropriate amount would be 222 mg once per day with food, which is usually much easier for the body to tolerate, especially when there is liver damage and significant weight loss.
          To help him regain weight, focus on high-calorie, nutrient-dense foods that are gentle on the stomach, such as avocados, nut butters, olive oil, eggs, full-fat yogurt, smoothies with added healthy fats, bone broth, and small frequent meals rather than large portions. Many people in similar situations also add whey protein or collagen protein, which can increase calories without causing discomfort.
          For liver support, it is common to include TUDCA, milk thistle, NAC, and omega-3 fatty acids, as these may help reduce liver stress and support overall function.
          Adjusting the dose and giving his body more nutritional support may help him tolerate the protocol better and stabilize his energy and weight.

          1. Justyna

            Thank you very much for all the information, we have made changes to the dosage and are adding supplementation.

  24. Tikvah

    Thank you so much for your website. I recently purchased 5 packages of fenbendazole 10gram powder packs, and I’m trying to figure out how much to use, this has helped. I am supposing each packet of 10grams will give me about 22 doses? Does that sound right?

    1. Fenbendazole.org

      Hello and thank you for a question.
      Yes, you are about right. A 10-gram pack contains 10,000 mg of fenbendazole. If your usual amount per day is around 444 mg, that comes out to roughly 22–23 doses per pack (10,000 ÷ 444 ≈ 22.5)

      1. Tony Ross

        We are looking to do the parasite cleanse protocol for 5 days and then again in 3 weeks for 5 days. Are we ok to use PANACUR 10% Fenbendazole which is an oral suspension containing 100mg Fenbendazole per ml. This is a cattle, sheep and horse wormer.

        If so, how do we work out the dose to take as it in liquid form? Would it be 500mg Fenbendazole be 5ml for example?

        1. Fenbendazole.org

          Yes, you can use a 10 percent fenbendazole oral suspension for the parasite cleanse protocol. A 10 percent suspension contains 100 milligrams of fenbendazole per millilitre, so the dose can be calculated directly from this concentration. For example, a 500 milligram dose is equal to 5 millilitres of the suspension. A 222 milligram dose would be 2.22 millilitres, and a 444 milligram dose would be 4.44 millilitres. You can measure accurately using a syringe marked in millilitres to ensure consistent dosing. The suspension can be taken with food to improve absorption.

  25. Sue Norcia

    Hello, My 10 year old pup, Penny, just underwent removal of 3 mammary masses. Two lower were adenocarcinoma (grade 3 on lower left, simple AC, and grade 2 on lower right – solid. lower right included some squamous cells). A third lump was benign. She also had a complete spay at the same time. Cytology came back with clean margins – narrow but clean on lower right. Lower right indicated vascular involvement.

    Prior to surgery, I had given her ivermectin and had given a test dose of Fendbenzadole but stopped the Fen because I’d heard there might be drug interactions with surgery drugs.

    I have both drugs. Fendbenzadole in a 500 mg capsule. She is 33/34 pounds. This 500 will be too much? Should I give it to her as 500 or cut it in half? Calculating, Ivermectin.. I had been giving her 1.5 mg a few days and off a few. I think her dose should be 3 mg if my calculations are correct. Do I have either of these right or should I change them?

    Also, she has a small round growth … soft.. which may or may not be anything significant. It is in the skin like a pimple on the lateral side of her left knee. There is another similar in the muscle tissue just distal to that in the hamstring area. Will the systemic fenben help this too… or should I go ahead and put some topical on that area? If so, what topical fenben do you recommend? (what I have is capsule… wondering if I can open and make a topical cream with the crystals? If so, what would be the medium to mix with the fenben to apply?)

    Her liver enzymes are okay.. AST normal – 33. ALT has been raised for a few years.. has come down from 300s and is now at 187.

    Thank you for your help.

    Sue

    1. Fenbendazole.org

      Hi Sue. Thanks for sharing Penny’s update.
      For her weight (33–34 lbs / ~15 kg), a 500 mg capsule is slightly above the typical range. You can split it roughly in half (about 250 mg daily) and give it 3 days on / 4 days off with food containing fat. That aligns well with her size and ensures good tolerance. Your ivermectin dose of around 3 mg sounds right for her weight. No need to rush, just continue spacing it out every few days as you were doing.
      Since Penny’s liver enzymes are stable and trending better, continuing milk thistle or general liver support alongside the protocol is a good idea.
      You’re doing all the right things -gentle, steady progress is key.

      1. Manohar Ram

        Can it be taken alongside dexamethasone 4 mg since it’s a steroid no interaction or negative effect right kindly confirm

        1. Fenbendazole.org

          Hello Manohar,
          There is no well-documented direct pharmacokinetic interaction between fenbendazole and dexamethasone, as they are metabolized through different primary pathways and exert their effects via distinct mechanisms. Fenbendazole mainly influences microtubule function and cellular metabolism, whereas dexamethasone acts as a glucocorticoid with anti-inflammatory and immunomodulatory properties. On a mechanistic level, there is therefore no clear scientific basis to assume that dexamethasone would inherently negate or interfere with fenbendazole’s activity.
          However, because controlled studies examining their concurrent use are lacking, it is not possible to categorically exclude all potential indirect effects. For this reason, routine monitoring of liver function and overall tolerance remains advisable when combining fenbendazole with any systemic steroid, including dexamethasone.

  26. Andrea

    Hello,
    I thank you for this website. My dad is 86 and it’s highly suspected he has liver cancer with large masses. I am confused about the dose needed of the fenben, based on his weight it shows 444mg per day but I see Joe’s protocol is only 222mg. Is this because Joe was a small man? My dad is 200lbs. I also see that he can take this daily but again Joe did not. Just not understanding the different instructions. Thank you!!

    1. Fenbendazole.org

      Our calculator is slightly modified to better reflect dosing by body weight and to provide flexible interval options based on what many people have found works best over time.
      Joe Tippens’ original protocol (222 mg, 3 days on / 4 days off) is still included on our site so people can compare and choose individually, but our calculator adjusts the amount proportionally for different body weights- Joe was indeed smaller, which is why his dosage appears lower.
      So it’s completely fine to follow the calculator’s guidance, or to use Joe’s original routine if you prefer. The most important thing is to stay consistent and monitor tolerance.

  27. Candice

    We found a large mammary tumour on our 10 1/2 year old English Bulldog on Tuesday evening. We got her into the vet (earliest appointment) on Friday for an FNA and x-rays of her chest. The vet found a second mammary tumor on the opposite side and later that evening, I found a third. The second and third are pea size. Unfortunately the chest x-rays showed 2 masses in her lungs plus 1-2 in her abdomen. The FNA and confirmed mammory tissue and nothing else. It’s most likely stage 4-5 mammary adenocarcinoma. She has no other symptoms. Her lungs sound clear, no swelling in her lymph in her neck. I am doing everything I can to give her more time.

    I have just received an order of 222mg/capsule of Fenbendazole. I also have a Turkey Tail 8x supplement, an 11 medicinal mushroom blend that also contains turkey tail, full spectrum CBD, Black Seed Oil, Milk Thistle, canine omega oils and Vitamin D3.

    I plan to start her on the Fenbendazole in the morning (we only feed 1 time per day but I started splitting her meals today to allow for a split in her supplement regime). I don’t have Ivermectin just yet but plan to get some on board to add to this protocol soon. I believe I read around 12mg/day hould be the correct dose for Ivermectin but I need to double check this.

    Her weight hovers between 38-40lbs. She is currently 18.4kg or 40lbs.

    I believe this means she should have 444mg Fenbendazole 1 time per day, 3 days on, 4 days off. I plan to give this to her with her breakfast which will also have the turkeytail plus the mushroom powder blend, BSO, Milk Thistle and Omega oils added to it.

    I have also made a mix of 1tbsp coconut oil, 1 tsp BSO, 1 drop Frankincense and 1 drop Myrrh as a topical treatment to put on her tumours.

    Can you confirm this is a good plan? Should we try a more aggressive approach if well tolerated?

    I’m not sure where to get Ivermectin from (we are in Canada and it’s getting more difficult to get here). Is it easily accessible in the US? My husband is in the US regularly for work.

    Thanks so much.

    1. Fenbendazole.org

      Hello, Candice. Thank you for a question.
      Your plan looks thoughtful and well put together. For a 40 lb dog, 444 mg once daily, 3 days on and 4 days off is indeed a standard schedule. Taking it with food containing fats is important for absorption, so giving it with her breakfast as you described is perfect. The supplements you listed, all provide good support. The topical mix is fine too if her skin tolerates it well. If she responds well and shows no harsh side effects, some owners choose to continue long-term or shorten the off-days slightly, but it’s best to start slow and observe first.
      You’re doing a great job giving her the best care possible. Keep us updated on how she does.

  28. John Baggett

    Hello and thank you for this service. I was recently diagnosed with Stage 2 lung cancer, I am a 112 lb male 75 years old since I was diagnosed I have been taking Ivermectin 3mg and Fenbendazole 222 mg. I’m also taking Hemp oil 1 dropper full, Soursop 1 dropper 1 methylene Blue gummy, 2500mg, Vitamin D3 1250 mcg once weekly, Curcumin with Turmeric Extract 500mg, Berberine 500mg and a couple of immune boosters. My problem is that I don’t know I see different posts about different people being cured of cancer but they’re all taking different amounts of Ivermectin and Fenbendazole. I started out taking 444 mg of Fenbendazole but then read from Joe Tippens protocol that he only took 222 mg and 1mg of Ivermectin yet some people are taking 24mg of Ivermectin and some people are taking 1 and 2 thousand mgs of Fenbendazole. I’m lost can you please help me . I sure would appreciate it and will be glad to post on your website my progress. Thank You so very much. God Blessings, John

    1. Fenbendazole.org

      Hello John,
      Thank you for reaching out and sharing your journey. We understand how overwhelming it can be to navigate all the different protocols and recommendations. There are indeed many conflicting protocols out there, which can make it difficult to determine the best approach for you.
      To clarify, Joe Tippens did not use Ivermectin in his protocol. His focus was on Fenbendazole. As for Ivermectin, since we are primarily an informational site for Fenbendazole, we cannot provide specific guidance on Ivermectin use. However, the standard recommended dose for Ivermectin is around 0.2 mg per kg of body weight. For someone weighing 112 lbs (around 51 kg), this would typically be about 10 mg per day.
      Regarding Fenbendazole, starting with 222 mg per day is common, but the appropriate dosage can vary. We recommend using our Fenbendazole dosage calculator, which will help you determine the best dose based on your specific body weight and needs. You can access the calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/.
      We hope this helps clear up some of the confusion.

    Hi, I’m Charmaine I’m 64.
    I’m new to this Group & thankful for any advice!
    I’ve been fighting Kidney cancer (Renal cell Carcinoma) since 2015,
    I had my L Kidney removed 2015, metastasis to R adrenal gland- removed 2019, now a tumor on my L adrenal gland.
    I saw my oncologist to go over my CT scan results from last week, the Tumor on my L Adrenal Gland has grown from 3.0 x 3.0cm to 3.6 x 3.2 cm,
    A normal adrenal gland is approximately 2cm, he says the tumor is inside & outside taking over my adrenal gland, he said the adrenal gland can stop functioning suddenly, (I only have one L adrenal gland & one R kidney), since I only have one adrenal gland & it’s severely compromised he said I could pass out & die at anytime! He was very blunt (I know my God is greater than this Dr report). I’m not sure if he’s trying to pressure me into starting this very strong/toxic immunotherapy? Keytruda etc
    My Endocrinologist said my L adrenal gland is still putting out sufficient cortisol.
    I was told the immunotherapy IV’s could kill my other kidney & end up on dialysis, I was told if they radiate the tumor it could kill the tumor but it will also kill the remaining adrenal gland then I would have to take Steroids the rest of my life to
    Live & if I accidentally miss a dose of steroids I would die as your body requires at least one adrenal gland.
    I’m trying not to be in fear, but I am questioning his motives. He’s scared my husband badly today, ofc he doesn’t want to lose me & is leaning towards what my Oncologist said today, to start the immunotherapy which has numerous risks as well.

    I’ve started taking Iver 18mg caps with LDN & Supplements.
    I’m trying to get some Fenben but I need a good quality since I only have one kidney?
    These are the other treatments I’m trying to find a good source?
    I’m in Oregon, I’m believing in Healing- “what I do in the natural God will do in the Supernatural”🙏

    Fenbendazole
    Albendazole (I heard this is gentler on kidney than Menben)
    mebendazole
    Methylene Blue

      Hello Charmaine,
      Thank you for sharing your story. It is admirable how you are navigating your journey and exploring all options for your health.
      Regarding Fenbendazole, we recommend choosing pure Fenbendazole with 99%+ purity in capsule form. Since you have one kidney, it is especially important to ensure the product is high-quality and free from unnecessary additives. On our website, we provide a link to a Facebook group where you can connect with others and find trusted sources for Fenbendazole.
      As for Fenbendazole versus Mebendazole versus Albendazole, Fenbendazole is often preferred due to its gentler effect on the kidneys and its potential support for cancer therapies. It has a lower toxicity profile, making it a good choice for your situation. Mebendazole is similar to Fenbendazole but might be slightly stronger in terms of toxicity. Albendazole is considered gentler on the kidneys but is not as widely used for cancer support as Fenbendazole.
      Regarding Methylene Blue, it is known for its antioxidant and mitochondrial support properties. It should be used cautiously with other treatments. While it may offer general health benefits, research on its effectiveness for cancer is still limited.
      We encourage you to continue learning and engaging with others in the Fenbendazole community. Wishing you strength and healing on your journey.

    Earlier, I asked a stupid question: “I’m asking for a friend who has a brain tumor.
    What concentration does the CBD oil, which is 25 mg in the protocol, refer to?
    Let me explain: I see that various concentrations of CBD oil are available on the market, so to reach 25 mg, the number of drops varies.
    What concentration does the protocol refer to?
    Thank you so much for your reply.”

    I’ve just seen that on the packages of different concentrations, the mg is indicated based on the drops.
    So, you don’t need to answer me.
    Thank you and I apologize if I wasted your time.

  31. Janet S.

    My 17.8lb pomski has a biologically high grade subcutaneous mast cell tumor thats been removed for the third time now and its come back just inches away from the original site just a week after his last tumor removal operation and has been deemed inoperable. His primary vet said she didnt want to risk putting him under so soon and since then has grown drastically and very agressive showing no signs of stopping or slowing down. Yesterday was the first seeing an oncologist and his prognosis is 1 month if responds to chemo well then 5 months. He had his first round of vinblastin. And is on Prenisone 5mg 1tab twice daily and atarax 10mg 1½tab twice daily and famotidine 10 mg 1tab twice daily. I want to do everything I can for him as he has been there for me thru the worst days of my life. I am doing as much research as i can with the time I have. Im so grateful to have found this page. I need some personalized guidance of proper dosage of fendbenazole is 222mg correct (approx. ½ teaspoon of the horse paste version 100mg/g) and recommendations for additional supplement are appreciated. I will be adding milk thistle to his food which consist of all protein high fat diet with Dr. Harveys Raw Vibrance/Paradigm. And tonight i ordered turkey tail mushroom to add as well. Is there anything else that i can add in order to help him and dosage will be helpful. I fear it will be any day its consuming the front half of his body and has hardening up and looks like its internally bleeding. I want to have a little more time with him he means the world to me.

    1. Fenbendazole.org

      Hello Janet,
      Thank you for checking the dosage with our calculator. For your 8 kg (17.8 lb) Pomsky, the calculator shows the recommended Fenbendazole dose is 222 mg per day, given once daily with food. Since your Safeguard paste contains 100 mg per gram, this equals about 2.2 grams of paste daily.
      The standard protocol suggests 4 days on and 3 days off, repeating weekly. However, because your dog’s mast cell tumor is very aggressive, it is reasonable to extend the schedule to 5–6 consecutive days or even daily if he tolerates it well. Be sure he stays hydrated and continue using liver-supportive supplements such as Milk Thistle, TUDCA, or NAC to protect his liver during prolonged use.
      You are doing everything right and giving him the best care possible. Please continue working with your oncologist for comfort and pain control, and adjust the schedule gradually based on how he responds.

  32. Dorice Ramsey

    I have 6 month old rescued puppies that Vet prescribed Panacur Fenbendazole. They weight approx. 25 lbs and want to use the Safe-guard equine dewormer (25 gram paste 10%, 100 mg/g) since much cheaper. One puppy already passed…refused to eat, lossed 1/3 his weight, pooped blood, so in bad shape. Vet gave me 3 grams of granules to be taken for 3 days. What dosage do I use of the equine paste? Calculator said 222mg daily…is that about a teaspoon?

    1. Fenbendazole.org

      Hello, Dorice. We are so sorry to hear about your puppy’s condition. You’re doing the right thing by stepping in and trying to help.
      If your vet prescribed Panacur 3 grams of 22.2% granules for a 25 lb puppy, that is equivalent to ~222 mg of fenbendazole per day (20 mg/kg).
      The Safe-Guard equine paste (10%, 100 mg/g) is one-tenth as concentrated, so you will need about 2.2 grams of paste per dose to deliver ~222 mg of fenbendazole.
      2.2 grams of 10% paste ≈ ½ teaspoon (a little less, depending on how thick your paste is).
      Give once daily for 3 to 4 days in a row.
      You can mix it with a bit of food to make sure they swallow it all.
      Make sure your puppy stays hydrated and eats something with the paste (don’t give on empty stomach).
      If symptoms like bloody stool or refusal to eat continue, see the vet again. Secondary infection or intestinal damage might need antibiotics or supportive care.

  33. Michelle Billups

    My dad 76 with prostate cancer all over his entire body end stage. He not walking hardly talking. We feed him. How do I get more fenbendazole. Where do I get the pills. Is it OK to use the horse paste

    1. Fenbendazole.org

      Hello, Michelle. Thank you for your message, and we’re sorry to hear about your father’s situation.
      Fenbendazole has been used by many individuals in similar circumstances, and while human-grade products are preferred for purity and consistency, animal-grade fenbendazole (such as goat or dog formulations) has also been commonly used by many people. If you’re using a paste or suspension, check that it lists “Fenbendazole 10% (100 mg/mL)” as the only active compound. There are some reliable suppliers online, just be sure that they have official website, provide certificate of analysis, has good reviews on real users sites like Trustpilot. Also, usually fenbendazole comes in paste, powder or capsules, not pills.

  34. Tony

    Ive started the ivermectin, fenben protocol.
    1000mg fenben for 3 days then 4 off
    Ivermectin 120mg daily.
    I split these over 2 doses. 12noon and 12 midnight.
    I wanted to add berberine + curcumin at 4pm and 8pm.
    Would 4hrs be long enough where it wouldnt interact negatively to iver and fenben .
    Start radiotherapy next monday….dr makis has mentioned 1g of fenben for aggressive cancers, debating whether to increase this to 5 days on/2 off

    1. Fenbendazole.org

      Hello, Tony, and thank you for a question!
      Yes, spacing berberine + curcumin about 4 hours after ivermectin and/or fenbendazole is is sufficient to avoid absorption interference. 5 days on / 2 off is also used in more aggressive protocols but may increase hepatic strain, so liver-enzyme monitoring is important.

  35. Richard Michael Katz

    Hi there, thank you so much for the calculator. I am also truly humbled at how you take the time (with such patience) to respond to every question.
    My name is Richard, and my dog, Sam (8-year-old, male, 18 kg Staffordshire Terrier) has just been diagnosed with a ‘well-defined round intra-axial mass in the right piriform lobe’. The mass is assumed to be a glial cell tumour / glioma.
    Sam started having ‘chewing gum’ seizures four weeks ago after an accidental bump to the head.
    He has been put on phenobarbital, which stopped the seizures.
    He has been on a raw diet his whole life (venison with fermented fruit and vegetables) and is a picture of health.
    I had been supplementing him with organic cold pressed coconut oil, CBD/A oil (blend 50:50 CBD and CBDA) and Bromelain (for anti-inflammatory, antihistamine properties — itching, and as a general tonic).
    The vet asked me to take him off the CBDA and Bromelain.
    Since the results came back (7 days ago, and 4 weeks since his first seizure), I have put him back on CBD (50:50 CBD/A – 15mg 2/day), bromelain (500mg 2/day) as well as adding spirulina (all with food).
    I have done quite extensive research on bromelain (since the vet asked me to take him off), discovering to my surprise some fascinating lab studies demonstrating bromelain inhibits glioma cell invasion, migration, and adhesion reversibly without harming cell viability. (I thought this might be of interest to you for your protocols.)
    CBD (and CBDA) are also shown to have anti-tumour action, as well as being highly synergistic with phenobarbital (studies show significantly reducing seizures).
    Anyway, here we are.
    My vet is a kind and open-minded young physician, but is very much locked into mainstream medicine.
    He is very cautious, but nonetheless, said if a fenbendazole / ivermectin treatment works with Sam, he would introduce it at his clinic.
    I reached out to Dr William Makis, but his team told me he did not adapt protocols for dogs but to explore fenbendazole. Do you think fenbendazole is appropriate for my dog’s tumour?
    I have used your calculator (dog/18kg) and it comes up with 444mg/day in the morning with food.
    Thanks for all the information on your pdf.
    I also plan to supplement with milk thistle (as directed, 250mg 2/day) and curcumin (can you confirm appropriate amount for dogs?).
    Thanks in advance,
    All the best
    Richard

    1. Fenbendazole.org

      Dear Richard,
      Fenbendazole is a benzimidazole carbamate with well-documented anthelmintic properties in veterinary medicine, but in recent years it has attracted attention for its potential anticancer effects. Preclinical studies have shown that fenbendazole can interfere with microtubule formation in malignant cells, disrupt glucose metabolism, and induce apoptosis without excessive toxicity. Because gliomas are highly glycolytic and depend strongly on altered energy metabolism, the mechanistic profile of fenbendazole suggests that it could have value as part of a multimodal strategy.
      For an 18-kilogram dog, the calculated dose of approximately 444 milligrams daily with food corresponds to protocols that have been circulated in veterinary oncology case reports and among integrative practitioners. This amount is consistent with published extrapolations based on weight and is within the range generally considered tolerable in companion animals. Since gastrointestinal tolerance and liver function can vary, it is important to introduce liver support such as milk thistle, which you have already included, and to monitor carefully for changes in appetite, stool, or overall energy.
      Bromelain is indeed interesting in the context of gliomas, since in vitro studies have demonstrated effects on tumor cell adhesion and migration. The combination with CBD and CBDA is also rational: cannabinoids have both anticonvulsant and possible antitumor activity, and synergy with phenobarbital for seizure control has been documented. Curcumin is another compound with low systemic toxicity and wide-ranging anti-inflammatory and anti-oncogenic properties; for canines it is typically introduced at about 15–20 mg per kilogram of body weight per day, often divided into two doses and given with a fat source such as coconut oil to enhance bioavailability. For an 18-kg dog, this would mean a target of approximately 300–360 mg per day, although some protocols use higher ranges depending on tolerance.
      Taken together, your current approach integrates metabolic reprogramming agents (fenbendazole, CBD/CBDA, bromelain, curcumin), liver and mitochondrial support (milk thistle, spirulina, coconut oil), and seizure control (phenobarbital). The scientific rationale for this combination is that each agent addresses a distinct but overlapping vulnerability of glioma cells: energy production, inflammatory microenvironment, oxidative stress, and invasive capacity. While clinical evidence in dogs is still limited, the mechanistic overlap and safety profiles make this a coherent plan that could plausibly complement standard care.
      In summary, the fenbendazole dose you derived is appropriate for Sam’s weight, the addition of milk thistle and curcumin is well-founded, and the supporting nutraceuticals you have chosen align with both experimental and preliminary evidence for glioma management. Close monitoring of tolerance, seizure activity, and quality of life remains essential, but the scientific reasoning behind your protocol is strong and well considered.

      1. Richard

        Thank you so much for taking the time to reply to me and share your knowledge and insight. I can’t thank you enough. I will keep you posted. 🙏

  36. Martin

    Was diagnosed with Pancreatic cancer one year ago. I was given three months to live and offered immediate surgery (Whipple) and chemotherapy. I waved off all standard treatments and started Fenbedazole (222 mg per day) three times a week. Eventually I moved dosage up to five and then six times per week. It’s now been a year and I’m in good health even though the tumor is still there. My Oncologist said everything looks stable and I’m doing well, however, he did say the tumor grew just a smidge, barely a millimeter. He didn’t seem to worried. Do you think I should increase Fenbendazole dosage to seven days a week. I’ve only been on six days a week dosage for about two months so I don’t know if I gave it enough time.

    1. Fenbendazole.org

      Dear Martin,
      Thank you for sharing this detailed update. A reported increase of approximately one millimeter is within the range of common measurement variability on serial imaging and can reflect differences in slice thickness, reconstruction kernel, patient positioning, or slice angle rather than true biological growth; local inflammation, edema, or evolving necrosis can also transiently alter apparent dimensions. In this context, a year of overall stability with preserved health is a strong signal that your current approach is being tolerated and is maintaining disease control. The six-days-on, one-day-off schedule is widely considered a high-exposure regimen; retaining a weekly recovery day is physiologically reasonable to support hepatic and gastrointestinal resilience while preserving cumulative pharmacologic pressure. Extending the same schedule for a longer assessment window and interpreting any future dimensional changes alongside symptoms and functional status is a prudent way to separate noise from trend. You are doing excellent work staying consistent, methodical, and attentive to tolerance, and we are genuinely glad to hear that you are feeling well after a year. Please accept our encouragement as you continue, and know that we are rooting for you.

    Hi

    Do you have a calculator for horse cancer dosages? Or is it the same as the parasite dosage? My horse has SCC and am looking to use Fenbendazole and Ivermectin. Any other suggestions? Thanks

    1. Fenbendazole.org

      Dear Monica,
      For horses, the fenbendazole dose is calculated by body weight. At 10 mg per kilogram, which is the commonly used amount in both parasite protocols and cancer protocols, a horse weighing 500 kilograms requires 5000 mg per day. This is consistent with what our calculator shows. The difference between parasite treatment and cancer use is not the milligram-per-kilogram amount, but the schedule. For parasites, fenbendazole is usually given once daily for 5 consecutive days, with the course repeated every 3 weeks. In cancer protocols, owners often adapt the same daily dose into a cycle of four consecutive days of treatment followed by three days off, repeating weekly. This cyclical pattern allows continuous pressure on tumor cells while giving the body recovery time.
      Ivermectin can be combined with fenbendazole. The standard reference dose is 0.2 mg per kilogram, which is around 100 mg for a 500 kg horse. Some owners give it on the same days as fenbendazole, while others prefer alternating days. In addition to oral dosing, ivermectin is sometimes applied topically to lesions, which many have reported as beneficial.
      Because these regimens are long-term, supportive care is important. Liver support with supplements such as milk thistle, TUDCA, or alpha lipoic acid is commonly used to protect against strain. Attention to diet, clean environment, and stress reduction can also contribute to tolerance and overall well-being.
      We hope this provides clarity and reassurance as you consider the next steps for your horse. Please feel free to contact us again if you need further guidance.

      1. Monica

        Thanks for your reply. Is it best to use the Fenbendazole and Ivermectin horse paste?

        1. Fenbendazole.org

          It is possible to use fenbendazole and ivermectin in the form of horse paste, and many owners do so because these products are widely available and relatively affordable. The choice of paste, granules, or liquid usually comes down to what is most convenient for you and your horse. What matters most is to check the label carefully for the exact amount of active ingredient, since concentrations can differ between brands, and then calculate the correct dose based on body weight. With paste formulations, it is especially important to measure the amount accurately so the horse receives neither too little nor too much. If you are consistent with dosing and pay attention to your horse’s tolerance, horse paste can be an effective and practical option.

  38. Holly

    Hi my 56 pound Airedale terrier was recently diagnosed with a cancerous tumor in his nose. I have heard that the combination of fenbendazole and ivermectin has been having wonderful results and dogs. I would like to start my dog Oscar on this protocol but I’m not sure I understand the dosing routine. Would he take both medicines on the same days and take them every day or or just a few times a week? Or do you take them on alternate days or do you take one for a few days on and then have a few days off? Thank you so much for any help you could give me with this. We love him very much and want to do everything we can to try and help him.

    1. Fenbendazole.org

      Hello Holly,
      Thank you for your message and for telling us about Oscar. We know how much he means to you.
      For a dog of Oscar’s weight (approximately 56 pounds, or around 25 kilograms), the reference amount of fenbendazole is 444 mg. A commonly used routine is to administer fenbendazole once daily for four consecutive days, followed by three days without treatment, and then to repeat this cycle every week. This approach allows for consistent exposure while also giving the body a short rest period.
      Ivermectin is dosed very differently, in much smaller amounts relative to body weight, and requires careful attention. Some owners choose to give fenbendazole and ivermectin on the same days, while others alternate the two to reduce combined stress. Another option is to begin with fenbendazole alone, and once tolerance is clear, gradually introduce ivermectin. Each of these approaches has been used successfully, and the key principle is consistency and close observation of how the animal responds.
      There is no single universal routine that fits every case, because every dog can respond differently. These regimens are generally maintained over the long term, and they are most effective when combined with supportive measures. Many owners choose to include liver-supportive supplements such as milk thistle and to pay attention to diet and overall health, which can be beneficial during ongoing use.
      We hope this helps provide clarity for Oscar’s care. Please feel free to reach out again if you need more information.

      1. Selena

        Hello,
        Let me just start off by saying this website is amazing!
        My furbaby was diagnosed with a primary lung tumor. Of course I’ve been trying to do everything I can to help her since diagnosis.
        I got the Panacur C 40 lb and 20 lb packets since she is 56 lb. The packs of course are for 3 days, so I have been doing those 3 days on and 4 days off.
        My question is, I was reading your advice to “Holly” and her dog is also 56 lb. But you advised her to do 444 mg a day. Well with the two packs I give my dog a day of the Panacur C, thats 666 mg. Am I giving her too much?! Also I have her on milk. Thistle chews that have other herbs in them but the milk thistle is only 75mg/day. I’m thinking that’s not enough support for her with the cancer and fenben? I also have her on Essiac Tea, a sprinkle of turmeric on her food, and 5 Defenders and Turkey Tail.
        Hope all that made sense. Thank you so much for your help!

        1. Fenbendazole.org

          Hello, Selena! You are doing a great job being proactive for your dog.
          Panacur C 40 + 20 lb packets = 666 mg total — that’s still within a safe range, just on the higher side. Many pet owners use 444–666 mg/day without issue, as long as the dog tolerates it well and liver enzymes stay normal.
          You can slightly reduce the dose to one 40 lb + half of a 20 lb packet (~500 mg) if you want to stay closer to the 444 mg mark, but what you’re giving now isn’t excessive or dangerous.
          Regarding milk thistle:
          75 mg/day is quite low for liver support during ongoing fenbendazole use. You can easily increase that to around 150–300 mg/day (silymarin content) for a 56 lb dog.
          Your use of Essiac Tea, turmeric, 5 Defenders, and Turkey Tail is supportive and fine to continue- those supplements overlap in antioxidant and immune benefits.

          1. Selena Welborn

            Thank you SO much! That makes sense.
            I just have 1 more question. I see a lot of people on my group pages use the Safeguard goat liquid (suspension 10%, 100mg/ml)100sold at Tracor Supply because it’s more economical (?)… Now that REALLY confuses me on the dosage. The suggested dosages by members in the groups seems to vary greatly. I tried to use your calculator but unless I’m missing something I don’t see anything for liquid. What would the correct dosage be of this be for my baby? Also confused about the 10% part… ?? THANK YOU AGAIN!!!

          2. Fenbendazole.org

            The 10% Safeguard goat suspension means that the liquid contains 100 mg of fenbendazole per millilitre. The same active ingredient and concentration are used across different formulations; the main difference is only in the carrier (liquid versus paste or powder). The dosage is therefore calculated according to the animal’s weight and expressed in milligrams of fenbendazole per kilogram of body weight.
            If, for example, the target dosage is 5 mg of fenbendazole per kilogram and the liquid contains 100 mg per millilitre, a 10 kg animal would require 0.5 mL of the suspension (because 10 kg × 5 mg/kg = 50 mg, and 50 mg ÷ 100 mg/mL = 0.5 mL). The same calculation applies regardless of species, provided the correct milligram-per-kilogram target is known for that animal and condition.
            The “10%” label can be confusing, but it simply reflects that 10 g of fenbendazole are present in every 100 mL of product – equivalent to 100 mg/mL. Because it is a liquid, accurate dosing should always be based on the concentration and body weight rather than on volume alone. Using a calibrated syringe or dosing device helps ensure precision, especially for small or young animals.
            It is also important to shake the suspension thoroughly before each use to achieve even distribution, as the active compound may settle over time.

    Hi. Thanks for putting together all this information on one site and being so active in responding!
    A family member has had breast cancer several years ago, and is still on some hormone suppressant drugs that she will hopefully be able to stop in the coming year. There’s a chance of a relapse at that point and I was looking for a Fenben or Ivermectin relapse protocol. Do I understand correctly that in her case the 3 days on, 4 days off protocol needs to be taken indefinitely?

    1. Fenbendazole.org

      Dear Jack,
      Thank you sincerely for your kind words and for sharing your family member’s history with us. We understand how important it is to plan ahead and to feel supported in preparing for every possible scenario.
      In response to your question, yes – the 3 days on, 4 days off protocol can indeed be maintained on an ongoing basis, including indefinitely. This schedule has the advantage of providing steady therapeutic exposure while also allowing the body a period of rest each week. Many individuals find it to be a practical and sustainable approach, particularly in situations where long-term use is anticipated.
      We wish your family member continued strength and stability, and we send our very best regards as you navigate the next stage of this journey. Please know that you are welcome to reach out to us again should you need further clarification or additional information.

    Panacur C 222 mg apparently contains only 20% fenbendazole, meaning each 222 mg capsule has 44.4 mg of fenbendazole. In contrast, Fenben Labs 222 mg is 98% pure fenbendazole. I’ve ordered Fenben Labs, how can I calculate the correct dosage based on this?” Thankyou

    1. Fenbendazole.org

      Dear John,
      Thank you for your message and for clarifying your question. Since Fenben Labs capsules are produced at approximately 98-99 percent purity, each capsule labeled as 222 mg provides almost the full 222 mg of active fenbendazole. This means that you do not need to perform additional calculations or weigh the contents – by taking one capsule you are already receiving the intended 222 mg of fenbendazole.
      If you wish to confirm the exact amount that is suitable for your own situation, we recommend using the dosage calculator available on our website. By entering the body weight, the calculator will indicate whether 222 mg or 444 mg is the appropriate daily amount, and it will also display the recommended weekly schedule of use. You can access the calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/

      1. Carolyn

        A 1g packet of Panacur granules (it does not come in capsules) contains 222mg fenbendazole as approx 20% of the packet contains the active ingredient and the rest is fillers. A 222mg capsule from Fenbenlab contains the same amount of fenbendazole, just with no fillers.

      Low/standard dose: ~222 mg per day
      Optimal dose: ~444 mg per day
      Since your suspension is 250 mg per 1 mL (assuming 1 mL = 250 mg fenbendazole), the low dose would be just under 1 mL per day, and the optimal dose would be about 1.75 mL per day.
      Take it with fatty food (like avocado, eggs, or olive oil) for better absorption.
      Keep your other supplements (Vitamin D + K, Omega 3, Vitamin E) as you already do, they’re generally fine to combine.

    Hello .
    I would like to ask if this calculator showing the correct amount of mg for parasite treatment for the dog.
    My dog weight 74 kg and calculator shows that i have to give him 3700 mg at once aday for 5 days in row. Its that number is correct ?
    I have Panacur paste for de worming horses which contains Fenbendazole 187.5 mg per 1 gram which means that 3700 mg is almost 20 grams and that Panacur syringe is 24grams for 600kg horse.
    If I use this calculator for de worming myself 80 kg weight then its shows that I need to take dosage 222mg once a day for 5 days.
    It must be something wrong with this calculator ..

    please help

    1. Fenbendazole.org

      Hello,
      Thank you for your question. The confusion arises from the difference between long-term cancer protocols and short-term parasite treatments. For cancer treatment in animals, fenbendazole is administered over extended periods, often with breaks, because continuous use could lead to accumulation in the body. For parasite treatment, the goal is short-term elimination. Treatment usually lasts only a few days and is then stopped, and if necessary, the course may be repeated after a short break.
      This is why the dosage may appear very high when calculated without context. In parasite treatment, the duration is short, so fenbendazole does not build up in the body. In your example, a dose of about 50 mg/kg for a 74 kg dog amounts to approximately 3,700 mg per day, but this would only be given for a few consecutive days. Therefore, the calculator is misleading if you attempt to apply it to both cases in the same way, since cancer protocols and parasite protocols are not the same.

    If its a dog that weighs 23 kg its calculated as dosage444. but in the directions it says the capsule is 222 ml. does it means the dog needs to take 2 capsules a day to reach the 444 dosage?

    1. Fenbendazole.org

      Dear Sara,
      It sounds like there may be a mix-up between milligrams (mg) and milliliters (ml). Fenbendazole dosing is always calculated in milligrams according to the animal’s weight, so the most important step is to confirm how many milligrams of fenbendazole are actually in each capsule you have. If a capsule contains 222 mg, then reaching a 444 mg daily dose would mean giving two capsules. Some products, however, are already made with 444 mg per capsule, in which case only one would be needed. Always base the dosage on the actual mg content of fenbendazole rather than the capsule volume.

      1. sara

        Thank you very much for your response! I have one more technical question: If I have pills containing 222 mg or 111 mg (or any other dosage), should the full 444 mg be taken all at once with a single fatty meal, or would it be more effective to spread the doses throughout the day with multiple meals until the total of 444 mg is reached?

        1. Fenbendazole.org

          It is generally recommended to take the full 444 mg fenbendazole dose at once with a single fatty meal rather than splitting it throughout the day.

          Fenbendazole is poorly water soluble but is absorbed better when taken with dietary fat. Taking it all at once with fat helps achieve a higher peak concentration in the bloodstream, which is thought to be more effective for targeting cancer cells. Splitting the dose into smaller amounts may lower that peak concentration and could reduce its potential impact.

          If you have 222 mg or 111 mg capsules, you would simply take enough capsules at the same meal to reach the 444 mg total.

            Hi,
            So our Barney a 15kg Cavapoo was diagnosed with Hemangiosarcoma April 2025 and also had his hind leg amputated. We have tried him with a lot of remedies and now want to try him on liquid Fenbendazole and ivermectin.
            The Fenbendazole we have is sheep’s which contains 100mg Fenbendazole per ml.
            Barney now has 5 very nasty skin tumors that look like raspberry’s, we clean and dress them every day but the one under his ear we are unable to dress it as where it is located.
            We need a strong protocol to attack the disease can you recommend and will the tumors ever disappear? Should also apply the Fenbendazole topically on the skin tumors?

            We are desperately looking for an answer to help our boy.

          2. Fenbendazole.org

            Hello Tony,
            Thank you for writing to us and for telling us about Barney. We know how much he means to you, and we admire the care you are giving him.
            For a dog of his weight, approximately 15 kilograms, the appropriate daily reference amount of fenbendazole is 222 mg. Since your liquid formulation contains 100 mg per milliliter, this equals about 2.2 milliliters per day. This can be given once daily, usually for four consecutive days, followed by three days off, with the cycle then repeated week by week. This routine allows for consistent therapeutic pressure while also giving the body a short rest period.
            Ivermectin can also be combined, but because it is dosed in much smaller amounts, care must be taken with measurement. Some owners prefer to begin with fenbendazole alone and add ivermectin later, either on the same days or on alternating days, depending on tolerance. Ivermectin may also be applied topically to skin lesions, and many people have reported using it in this way alongside oral dosing.
            The tumors may shrink, stabilize, or in some cases regress, but each case is unique. Fenbendazole works systemically, which is why the main approach is oral dosing. Keeping the lesions clean and dressed, as you are already doing, is very important for supportive care. To protect the liver during ongoing use, many owners add supplements such as milk thistle, TUDCA, or alpha lipoic acid, which are often chosen to help maintain healthy liver function.
            We hope this guidance provides clarity and support as you move forward. Please know that we send you and Barney our very best wishes.

    i have been fighting for 5 years. about 1 year ago it became metastatic in my longs started one Immunotherapy .it was so bad on my body they had to stop.but i was taking fenben 222 6 six times a week 6 weeks before immunotherapy 3 months later pet scan showed half of the nodule next 3 days it was completely gone. have been taking lower doses butt my ast liver gets a little high would like to take the normal dosage .how high could my ast get without being a bad problem.any ideas will help.and i thank God for the wonderful things you do

    1. Fenbendazole.org

      Hello James,
      Thank you so much for your kind words, and we are truly glad to hear that your scans now show no nodules, that is a huge milestone and something to be grateful for.
      Regarding your AST levels, a mild elevation is not typically a reason for immediate concern. What becomes more significant is if the values increase to several times above the upper limit of normal; in that situation, it would be wise to take a break from fenbendazole for a few weeks to allow your liver time to recover. In the meantime, you can support liver health with supplements such as TUDCA or milk thistle, combined with a clean and nutrient-rich diet, plenty of fluids, and adequate rest. Regular monitoring is important so you can track how your body responds and adjust your protocol if needed.
      It is wonderful that you are in a position to focus now on maintaining your progress and supporting your overall health.

  45. Mysty

    Hi there – My 11 year old German Shepherd mix had a tumor on her leg removed. It is a Sarcoma, cancerous – they said it tends to be aggressive and wouldn’t be surprised if the tumor came back in the original location eventually. They got as good of margins as they could given that the area doesn’t have a lot of tissue. There’s no evidence that the cancer had spread, but of course one never knows. She does seem to have one other fatty lump on her, which she’s had for a while and wasn’t anything to worry about we were told. Regardless, I was looking into putting her on FenBen and got the liquid type, but have since gotten a little confused over dosage – calculator says 444mg, 4 days on, 3 days off. The dose in the syringe looks very small – should that be the case? I just want to make sure that what I’m giving her is apples to apples vs. the tablets or other version of FenBen. Also, I’d love any other suggestions of supplements that might compliment this protocol. Thank you in advance for your help!

    1. Fenbendazole.org

      Hello Mysty,
      Fenbendazole dosing is determined by the amount of active ingredient (fenbendazole) in milligrams per kilogram of body weight, rather than the physical volume of the product. This is why the amount in the syringe may appear small. It is concentrated and measured based on weight, not size. For an 11-year-old German Shepherd mix, the commonly referenced therapeutic dose for cancer support is around 20 mg of fenbendazole per kilogram of body weight, given for 4 days on and 3 days off. However, it is essential to confirm that the liquid formulation you purchased lists the exact milligrams of fenbendazole per milliliter so you can ensure the correct total milligram dose is being administered.
      Our online dosage calculator can help determine the correct total milligram amount based on your dog’s weight. Once you have that number, you can match it to your product’s concentration (mg per mL) to figure out the exact volume to give. You can access it here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      In addition to fenbendazole, many people choose to include supportive supplements such as curcumin, CBD oil, milk thistle (for liver support), omega-3 fatty acids, and medicinal mushrooms (e.g., turkey tail) to complement the protocol and support overall immune function. These are not a replacement for primary treatment but may help optimize metabolic and immune resilience.

      1. Carolina

        Hello
        My 7-year-old dog is battling hemangiosarcoma. He had his first surgery to remove his spleen, which ruptured with the tumor, and today (almost 3 months later) he had a second surgery to remove more blood from nodules that ruptured in the mesentery. The big problem now is that during today’s surgery, the doctor found new nodules in his liver that could rupture at any time and couldn’t be removed. If he starts with a dose of 444mg on a 4-day on, 3-day off schedule, would he have any chance of survival?
        What are the doses of the other supplements recommended? He weighs 30kg.
        Thank you

        1. Fenbendazole.org

          Dear Carolina,
          Thank you for your message regarding the treatment of your dog with hemangiosarcoma. I understand the complexity and seriousness of the situation.
          The fenbendazole dosage of 444 mg for a 30 kg dog is appropriately calculated according to our dosage guidelines. Considering the advanced stage of the disease with hepatic involvement, the administration schedule of 4 days on and 3 days off may be adjusted to 5 days on and 2 days off in order to provide more consistent therapeutic exposure while still allowing a short recovery period.
          In addition to fenbendazole, several supplemental agents are commonly used in integrative approaches to support overall health and potentially enhance therapeutic benefit. Suggested doses for a 30 kg dog include: Vitamin E at 200-400 IU daily, Vitamin D in the range of 1000-2000 IU per 10 kg body weight daily, Curcumin at 300-500 mg daily, and fish oil providing approximately 30-50 mg/kg EPA+DHA daily. Hepatoprotective support may be provided with silymarin or TUDCA, while melatonin in doses of 3-6 mg in the evening has been reported to aid in antioxidant and circadian regulation.
          While these measures cannot be regarded as curative, they may contribute to maintaining quality of life and possibly extending survival time. Monitoring of liver function is particularly important in this context, since hepatic tissue is already affected by metastatic disease and additional stressors should be avoided.

    Hello,

    Hope you’re well.  Thank you for putting this site together and providing all this good information.  My cat has osteosarcoma in his left hind leg that I found out back on 5/21/25.  I started him on a regimen of fenbendazole at 222mg 5 weeks ago, 3 days on and 4 days off.  He’s a around 8-10 pounds.

    It seems the cancer is getting worse because he’s having a bit more trouble walking and I noticed more swelling in the cancer affected area but he’s still eating, drinking, purring, and going in his litter box, just having a bit of trouble passing stool and I think that’s because he’s not as mobile.

    I wanted to get your thoughts on if I should change something? I did 3 days on, 4 days off because he’s almost 16 and didn’t want to push his liver too far but I’m also giving him a liver supplement in the morning with his food.  Should I start giving fendendazole 4 days on instead of 3 now?

    Thank you again for your time.

    1. Fenbendazole.org

      Dear Tom,
      Thank you for your message and for the care you are giving your cat. Osteosarcoma is a challenging diagnosis, particularly in an older animal, and your cautious approach is entirely understandable. The current fenbendazole schedule 222 mg, three days on and four days off is gentle and appropriate for a 16-year-old cat. However, given the signs of progression you described, it may be reasonable to adjust the schedule slightly to four days on and three days off, especially since you are already providing liver support.
      Your cat’s continued appetite, hydration, purring, and use of the litter box are all positive indicators. The difficulty with passing stool may be related to limited mobility or pressure from the tumor, both of which are common in such cases. As you consider this adjustment, closely monitor his general well-being, and continue supporting his liver function. Your attention to detail and commitment to his comfort are truly commendable.

    Iv’ve been on a protocol because of a PSA of 6 with a free percentage of 21%. My concern was the ExoDx Prostate test which put me at 50% chance of High Grade Cancer. I stated a protocol of 2×222 Fenben, 40mg of Ivermectin (Injectable0 that I take orally. Also 1000 Lipsomal Artemisiinin. Was fine for a while but now I feel wobbly and tired. Quite the Ivermectin and Artemesinin last night but took the Fenbenz today, still feel wonky? Could the Fenben be the culprit. Even had urine sample taken to rule out a UTI.

    1. Fenbendazole.org

      Hello Ralph,
      Thank you for sharing your experience. Based on what you described, it is highly unlikely that fenbendazole at a dose of 2×222 mg per day is the cause of the symptoms you are experiencing. This dosage is commonly used in active cancer protocols and is generally considered safe and well tolerated, even over extended periods.
      The symptoms you mentioned – feeling wobbly, tired, and generally “wonky” – are much more commonly associated with high doses of ivermectin. A dose of 40 mg of ivermectin is significantly higher than the standard range (typically 0.2–0.4 mg per kilogram of body weight), and many people report neurological side effects such as dizziness, balance issues, or fatigue when the dose is too high or increased too quickly.
      It was a good decision to pause both the ivermectin and the artemisinin. If you continued fenbendazole alone and the symptoms persist, it is worth giving your body a short break from everything to reset. However, if you start feeling better without the ivermectin, it is very likely that it was the main contributor to the side effects, not the fenbendazole.
      If you do choose to reintroduce ivermectin later, consider lowering the dose significantly and increasing it more gradually. Many people who use it long term stay within the lower dose range and avoid side effects that way.

  48. Rob

    Hello again,
    My girlfriend had surgery 10 days ago after cervical cancer returned after 4 1/2 years. A total of 20 out of 40 lymph nodes were affected and were removed. In addition, her uterus and one fallopian tube were removed. Fortunately, no other organs appear to be affected. Chemotherapy, radiation, and immunotherapy will begin in the next few weeks. The professor was not familiar with fenbendazole and reacted skeptically. I am trying to convince my girlfriend to take it, since it has little effect on the liver, correct? The only thing is that there should be a time interval between taking it and chemotherapy. Would you start fenbendazole therapy at the same time as chemotherapy, radiation and immuntherapy? Are there any (serious) interactions to be expected? She is currently still taking heparin as a blood thinner (for another 4 weeks).
    Thank you so much & greetings from Germany
    Rob

    1. Fenbendazole.org

      Hello Rob, and thank you for your thoughtful message.
      First, it is completely understandable that your girlfriend’s medical team may be skeptical about fenbendazole – it is not part of conventional oncology guidelines, and most physicians are unfamiliar with its use outside veterinary medicine. That said, many individuals have integrated it into cancer support protocols worldwide, especially when standard therapies are underway or planned.
      Fenbendazole is generally well tolerated and not known to significantly burden the liver, especially when taken in standard doses (usually 222–444 mg/day depending on body weight). People with liver involvement often use it safely, especially when combined with liver support supplements such as milk thistle or TUDCA. Still, monitoring liver enzymes is always advisable during combined therapies.
      As for combining fenbendazole with chemotherapy, radiation, or immunotherapy, there is no known serious interaction, but also no formal studies confirming safety or synergy. Many people choose to start fenbendazole before or alongside chemotherapy, often with a 1- to 2-day gap around infusion days to avoid additional stress on the body. Others begin during recovery days between treatment cycles.
      It is also important to note that heparin use does not appear to interact with fenbendazole, and no major clotting risks have been reported in connection with it. Nonetheless, if she is very recently post-surgery and still on anticoagulants, it may be best to introduce fenbendazole gradually, starting with a low dose and observing her response.
      In summary, yes – it is possible to begin fenbendazole during chemo, radiation, or immunotherapy, but it should be done cautiously and gradually, with attention to timing and her body’s reactions. Adding strong liver support and hydration can be especially helpful.
      Wishing you both strength and clarity during this time. Warm greetings back to you from here.

    Hello, here on stage 4 ovarian cancer, on Dexamethasone and other anti-inflammation meds. Feb Ben is not found, is Mebendazole a good substitute? please advise on dosage and other meds to combine.
    Thank you very much

    1. Fenbendazole.org

      Dear JN,
      Thank you for your question.
      Mebendazole and fenbendazole are chemically related and belong to the same drug class (benzimidazoles). Many people use mebendazole as a substitute when fenbendazole is not available, and it has also been studied for its anticancer properties. While fenbendazole is often preferred due to better absorption and anecdotal reports of higher effectiveness, mebendazole remains a reasonable alternative.
      For stage 4 ovarian cancer, mebendazole is usually taken at 100 mg once or twice daily, though some individuals increase the dose gradually based on tolerance. It is generally well tolerated, but liver enzymes should be monitored if taken continuously.
      Common supplements often combined with benzimidazoles include vitamin D3, curcumin, CBD or THC oil, milk thistle or TUDCA for liver support, and zinc or quercetin to support immune and metabolic pathways. Since your current medications include dexamethasone and other anti-inflammatory drugs, it is a good idea to introduce mebendazole gradually and monitor for any additional strain on the liver.

  50. Ivan

    I have a question. Based on the MSCC theory, does the protocol recommend taking IVERMECTIN at a dose of 0.5 to 2 mg per kilogram of body weight, three times a week? For example, for someone who weighs 70 kg, the correct dose would range from 35 to 140 mg per dose, taken three times a week. Is that correct? And is it safe to combine this with fenbendazole?

    1. Fenbendazole.org

      Hello Ivan,
      Thank you for your question. We are an informational page focused on fenbendazole, so our guidance on ivermectin is limited. While some alternative protocols mention ivermectin, we do not provide official dosing recommendations for it. The range you mentioned—0.5 to 2 mg/kg—is significantly higher than the more commonly referenced 0.2–0.4 mg/kg, and a dose of 140 mg for a 70 kg person would generally be considered excessive and potentially unsafe without medical supervision.
      As for combining ivermectin with fenbendazole, many people do so, often alongside other supplements, but there is limited data on long-term safety or interactions. If used together, it is best to start slowly and monitor for any adverse effects.
      To determine a safe and appropriate fenbendazole dose, we recommend using this official calculator:

    Hello,
    My 83 year old mother was diagnosed with Waldenstrom’s Macroglobulinemia.
    Would FenBen help her?

    She has severe rheumatoid arthritis and anemia. Off medication because they were hurting her liver.

    The doctor prescribed her Brukinsa, which she will probably take because she follows mainstream.

    I thought I would research alternatives in case the Brukinsa makes her feel bad and she’s willing to look at other options.

    Thank you for your help.

    1. Fenbendazole.org

      Dear Stacy,
      Thank you for reaching out. Waldenström’s Macroglobulinemia is a rare and slow-growing type of non-Hodgkin lymphoma, and while there is no official fenbendazole protocol specifically for this diagnosis, many people with various forms of lymphoma and blood-related cancers have used fenbendazole as part of a broader supportive protocol.
      Fenbendazole is generally considered well tolerated, even in older individuals, but since your mother also has severe rheumatoid arthritis and a history of liver sensitivity, any new supplement—especially something off-label like fenbendazole—should be introduced carefully and slowly. Liver support (such as milk thistle or TUDCA) is often used alongside it to help minimize any potential strain.
      If she does go on Brukinsa and experiences difficult side effects, some people choose to start with fenbendazole alone or in combination with supportive supplements like curcumin, vitamin D3, and zinc, depending on her tolerance. There is no guarantee of effectiveness, but many have reported improved energy, stability, or even stabilization of lab values while using it as part of an integrative approach.

    Hi there, my 78yr old father has just completed 8 weeks of radiation therapy for prostate cancer. I’ve got him 150mg tablets of fenbendazole and 12mg tablets of ivermectin, alongside vitamin C, zinc, and vitamin D supplements. His body weight is approximately 72kg. What do you recommend for the protocol to prevent a cancer relapse? Thank you so much.

    1. Fenbendazole.org

      Hallo Steve,
      Thank you for your message. Given your father’s current status following radiation therapy and the goal of preventing cancer relapse, a relapse prevention protocol would be appropriate.
      To determine the correct dosage and schedule of fenbendazole based on his weight (72 kg), we recommend using the official dosage calculator available here:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      According to his weight, the appropriate dose would be 222 mg of fenbendazole. Since you have 150 mg tablets, he can take one and a half tablets per dose to reach the correct amount.
      It is excellent that you are also including supportive supplements such as vitamin C, zinc, and vitamin D, as these may help support immune function and overall recovery.

  53. Ines

    My father has a cholingiocarcinoma in his liver. It’s quite large and has a residual liver capacity of 30%. I have a lot of apprehension about using it, especially since no one in Europe (Germany) supports it. Is there still hope for a poorly functioning liver, or is it too dangerous?

    1. Fenbendazole.org

      Dear Ines,
      It can still be used, but with a liver working at only 30%, it has to be done very carefully. Fenbendazole itself is usually well tolerated, but any added strain on the liver could make things worse if dosing is too high or if there is no liver support in place.
      People in similar situations often use lower doses and combine it with strong liver support like TUDCA, milk thistle, and NAC to help protect the liver while the protocol does its job. It is not a guarantee, but it is not automatically too dangerous either, as long as it is started gently and the liver is supported the whole time.

  54. Sunsrise

    A relative of mine had an aggressive bladder tumor removed, but unfortunately, it has recurred at the same site just two months after the surgery. He is now awaiting another operation, which is scheduled for next month. Please advise on the appropriate dosage and duration of treatment he should follow in the meantime.I’ve seen that there are different protocols some with a higher dose of 444 mg per day without breaks, and others with 222 mg per day. In some sources, the higher dose is recommended for very aggressive cancer. Thank you for providing the protocol.Please kindly provide the most accurate protocol for his case. Thank you very much

    1. Fenbendazole.org

      Hello, and thank you for a question.

      Start with a lower dose:
      222 mg per day.
      Take with food containing fat (e.g. coconut oil, eggs, or fish oil) to enhance absorption.
      Use this dose for at least 3–5 days to check for tolerance.

      If well tolerated and cancer is aggressive, increase to:
      444 mg per dayy.
      Continue without breaks unless liver function worsens.

      Dosage should be weight-based:
      Refer to the calculator

      Monitor liver function:
      Test ALT, AST, GGT, and bilirubin before starting
      Recheck every 2–4 weeks
      Stop or reduce if liver enzymes rise significantly

      Consider liver support supplements:
      TUDCA (250–750 mg/day, divided doses)
      Milk thistle extract (silymarin aprox. 600 mg/day)
      NAC (600–1200 mg/day)

    Just wrapped up a 5 day course of Fenben using the parasite protocol. It’s now the morning of day 6 and I’ve seen virtually no change in symptoms. Parasite protocol recommends another course in 3 weeks. Why should I wait that long? What else can I do to knock these bugs out?

    1. Fenbendazole.org

      Hello, and thank you for a question.
      The gap is based on the parasite life cycle. Most parasites lay eggs that hatch around the 21-day mark. Fenbendazole mainly kills adult parasites, not eggs. The wait allows new larvae to emerge so they can be targeted in the next round. You can also use Use enzymes like serrapeptase or lumbrokinase. Consider herbal antimicrobials like neem, black walnut, or clove. Eliminate sugar, alcohol, and ultra-processed foods.

  56. Ed

    Have you any info on Squamous cell carcinoma that will work? Doesn’t seem to do anything after a month and a half with Ivermectin and fenben

    1. Fenbendazole.org

      Hello, Ed.
      Squamous cell carcinoma can be harder to shift with just Fenbendazole and Ivermectin. These two work best on fast-growing, highly glycolytic tumors, and SCC is not always that type.
      DCA is often a stronger option in cases like this. It targets mitochondrial dysfunction directly and works well in solid tumors, including SCC. You need to take high-dose vitamin B1 with it to protect the nerves. Curcumin and EGCG are also good additions because they affect inflammation and cancer signaling. Some also try 4PBA or artesunate if available.
      Make sure Fenbendazole is taken with fat, and Ivermectin with food. If the body is not absorbing well or if the liver is under stress, it can block the effects. Use TUDCA or NAC for support if needed.
      If you can, track the tumor with pictures, blood markers, or imaging. Some things shift slowly or from the inside out. Let me know more details if you want to build a stronger protocol.

  57. Rob

    Hello everyone, and thank you for all the information.
    My girlfriend (37 years old) has been diagnosed with recurrent cervical carcinoma, which has now affected the lymph nodes in the pelvic area. Additional metastases in the pelvic area.
    Surgery next week, then probably chemo.
    We are considering starting with Fenbendazole. Is it likely to be effective against this type of cancer?
    I have read different recommendations here regarding simultaneous chemo. Should we still take Fenbendazole?
    Should a combination with ivermectin and/or methylene blue be considered?
    I would be very grateful for your advice!
    Greetings from Germany
    Rob

    1. Fenbendazole.org

      Hi Rob, and welcome.
      Yes, Fenbendazole may be helpful in cervical cancer, especially since these tumors are often glycolytic. There are no clinical trials specifically for cervical cancer, but its mechanism and real-world reports suggest it can be a supportive option. Many continue Fenbendazole during chemotherapy, but some choose to pause for a few days before and after infusions. This is because chemotherapy targets fast-proliferating cells, and Fenbendazole may slow down cancer cell division. If cancer cells are not actively dividing, chemo may not be as effective. Taking a short break allows chemotherapy to better hit its target while minimizing any potential interference. Ivermectin is sometimes added later, starting at 0.2 mg per kg a few times per week, but it is best to introduce one thing at a time and watch closely. Methylene Blue may be helpful in cancer support because it targets cancer cell metabolism in several ways. It improves mitochondrial function, which is often damaged or suppressed in cancer cells, and can help shift energy production away from the glycolytic pathway that many cancers rely on. This makes it harder for cancer cells to survive and grow. It also acts as a redox agent, helping to balance oxidative stress. It may help with fatigue, brain fog, or mood by supporting mitochondrial function and increasing cellular energy. However, it should not be used with SSRIs (selective serotonin reuptake inhibitors).

    Found a spot on liver and after biopsy they determined it was stage 4 colon cancer. Gave about a year to live. What protocol and dosing should person be using? Thanks in advance for your help.

    1. Fenbendazole.org

      Hello, Nick. Really sorry to hear about the diagnosis.
      When colon cancer spreads to the liver, time is critical, but there are still meaningful steps that can be taken. Fenbendazole is often used at 222 mg per day (use our calculator: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/ ) with food to help absorption. Ivermectin can be added at around 0.2 mg per kilogram of body weight a few times per week, introduced slowly to watch for any side effects. DCA is another option people use, usually daily or in cycles, and it should always be paired with high-dose vitamin B1 to protect the nerves. Some also add 4PBA if available. For liver support, TUDCA or NAC is commonly used. Curcumin, EGCG, vitamin D3 with K2, zinc, magnesium, and fish oil are supportive and well tolerated. A low-sugar, anti-inflammatory diet can help. If chemotherapy is part of the plan, pausing Fenbendazole a couple of days before and after the infusion may help, since Fenben slows cancer cell division and chemo works best when cells are actively dividing.

  59. Linda

    I have an inflamed cervix. And some abnormal cells discovered through a Pap smear. I’m hesitant about getting a biopsy because I heard it can make cancer spread. I would like to start the protocol. Is there a food plan that is suggested? Do I have to stay away from fruit?
    Thank you for this wonderful website and everything you’re doing.

    1. Fenbendazole.org

      Hello, Linda. Thank you for the question.
      Restrict high sugar fruits (like bananas, grapes, and mangoes). Small amounts of low-glycemic fruits (like berries) are acceptable in moderation.
      Prioritize high quality protein, healthy fats (omega-3s, olive oil), cruciferous vegetables, and fiber.
      You can begin the fenbendazole protocol at any time.

    2. Rob

      NONE of the numerous studies have confirmed that a biopsy causes cancer to spread. The negative aspects massively outweigh the positive ones. Know your enemy.

  60. Manny

    Hi, my 70LB Labrador was diagnosed with Lymphpma/Thymoma and I’m ready to try Fenben. I’m getting conflicting results on the correct dosage though. Your suggestion of or the cancer dosage is about 10x more than what other sources are saying.

    I was told to start with 222mg (about a quarter of 1 4g packet). Is this to little? This seems to follow the Joe Tippens dosage. Why is yours much higher?

    1. Fenbendazole.org

      Hello, Manny!
      For a 70 lbs dog our calculator shows 444 mg. You may have selected parasite treatment if you got much higher number. While 444 mg is higher then 222 mg you have been advised, we want to note, that dogs have much shorter digestive tract, so the absorption is much lower then in humans, that is why it may seem a little bit high, but it makes perfect sense.

      1. Cristie Lee

        I believe I have parasites. I have been tested for everything else. What is the protocol for fenbendazole? Can I add overheating with it and do i need a binder?

        1. Fenbendazole.org

          Dear Cristie,
          Thank you for reaching out. If you suspect you have parasites and want to use Fenbendazole, it is important to follow the appropriate dosage and approach. Fenbendazole is commonly used for parasitic infections, and while a binder is not absolutely necessary, you may consider using one if you are concerned about detoxification. Common binders like zeolite, bentonite clay, or activated charcoal can be used if you feel they are needed, but they are not essential for everyone.
          When taking Fenbendazole, it is crucial to support your liver, as the compound is metabolized there. We recommend milk thistle or TUDCA for liver support during your protocol.
          For specific dosing and to ensure you are following a safe and effective regimen, we highly recommend using our Fenbendazole dosage calculator available at https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/. The calculator will guide you through the appropriate dose based on your body weight and specific needs.
          Wishing you the best on your healing journey!

    Hello, could you give me some advice for my father who has Parkinson’s disease. He is 75 years old and weighs 67 kg. I would like your opinion on the dosage of fenbendazole. Thank you !

    1. Fenbendazole.org

      At this time, there is too little evidence to say that fenbendazole is helpful for neurodegenerative diseases like Parkinson’s. Most of the interest comes from its theoretical potential—fenbendazole reduces inflammation, and may support cell detoxification, all of which are relevant in neurodegeneration.
      However, fenbendazole does not cross the blood–brain barrier well, which limits its direct action on brain tissue. While it may support general cellular health, there is no strong data to suggest meaningful benefit in conditions like Parkinson’s.

  62. Richard

    Good evening, Joe. I have a 10 year-old black lab 55 pounds just diagnosed with bladder cancer. What would be my routine for her we don’t know what state it’s in. Can you give me an idea what to start off with? Thank you very much..

  63. Casey

    Hi, I’m looking for guidance on starting the fenbendazole protocol. The patient is currently dealing with aggressive ovarian cancer that has unfortunately spread to the liver and stomach. At the moment, her appetite is very low and she’s not eating much. Given the advanced stage and her limited food intake, I’m wondering what dosage would be appropriate to begin with, and how best to administer it under these circumstances. Any advice or experience would be deeply appreciated

    1. Fenbendazole.org

      Hello, Casey and thank you for a question.
      Given her limited food intake and weight loss, she should start slowly, at a safe dose of 222 mg, 4 days on and 3 days off. If you notice no adverse reactions and your overall health allows for more, you can increase the dose and frequency (6 days on and 1 day off). Also, monitor liver enzymes at least every 1-2 months to see if they are increasing.

    Can you use the pet stir bought fendbendozle for a parasite cleanse? And do u recommend using ivermectin and praziquantel along w it to hit all the different parasites at once?

    1. Fenbendazole.org

      Hello and thank you for your question.
      Yes, fenbendazole, ivermectin and praziquantel each fill a different part of the “worm-control puzzle”.
      Fenbendazole for: Roundworms/Ascarids; Hookworms; Whipworms; Many lungworms; Some tapeworms.
      Ivermectin for: Heartworm Dirofilaria immitis prevention (kills L3/L4 larvae); Most migrating or vascular nematode larvae; Some external mites & lice.
      Praziquantel or Niclosamide for: Nearly all tapeworms

    Bonjour et merci pour votre travail

    Je commence la chimio le 12 juin , 4 cures de CE ( 1 par 15 jours) puis 12 de Taxol ( 1 toutes les semaines )
    Je prendrai également du Desmodium au jour 6 à 11 .
    Quand prendre le Fenbendazole
    Merci pour votre réponse

    1. Fenbendazole.org

      Hello, Cristine, thank you for a question.
      Fenbendazole works by inhibiting the proliferation (growth and division) of cancer cells. It disrupts their ability to form proper microtubules — structures needed for cell division.
      Chemotherapy, on the other hand — especially drugs like Cyclophosphamide, Epirubicin, and Taxol — target rapidly dividing cells. That is how they kill cancer.
      So here is the key idea:
      If you take Fenbendazole right before chemo, you might slow down cancer cell division, making chemo less effective, because the drugs have fewer fast-dividing cells to attack.

      1. Jenn

        I have an autoimmune disease called Primary Bilary Cholongitis. Would this be safe for me to take for parasites?

        1. Fenbendazole.org

          Thank you for a question, Jenn.
          fenbendazole is mainly metabolized in the liver and has been associated (rarely) with elevated liver enzymes, hepatitis, and in very rare cases liver failure-especially in people who already have liver disease.
          Because of this, most guidelines list pre-existing liver disease as a relative contraindication or at least a strong precaution.
          Monitoring liver enzymes (AST, ALT, ALP, bilirubin) is usually recommended during treatment if there is any hepatic condition.

    I heard that Fenbendazole is helpful topically for skin cancer and/or precancerous sun damaged skin. I’d like to purchase 100% pure fenbendazole and mix it with something healthy like castor oil for topical skin application. How would that best be done and what do you recommend for the most effective treatment for skin cancer? Thank you for your excellent website. I look forward to reading your response
    Resending for a response
    Please email me your response

    1. Fenbendazole.org

      Fenbendazole is primarily used orally, but some people have explored topical application for skin conditions like precancerous sun damage or skin cancer. If you plan to prepare a topical fenbendazole treatment, here are some general recommendations:

      Use 100% pure fenbendazole powder and mix it thoroughly with a carrier oil such as castor oil, which has moisturizing and anti-inflammatory properties.

      A typical concentration might start around 1–5% fenbendazole by weight in the oil, but exact dosing is not established.

      Apply the mixture gently to the affected skin area once or twice daily.

      Perform a patch test on a small skin area first to check for irritation or sensitivity.

      Protect treated skin from further sun exposure and consult a healthcare professional, especially if using alongside other treatments.

      For skin cancer or precancerous lesions, medical evaluation remain important.

  67. Zena

    Hello, my mother has carcinoma of gallbladder with liver metastasis, but all thru bloodwork around her liver are very good. and I want to try this with her, she tried chemo and got very sick and weak, her appetite is done energy levels are down. With this product Panacur C Canine Dewormer (Fenbendazole), 4 Gram, does that mean one whole pack everyday mon-saturday or should we start with every other day?

    for how many weeks would you suggest repeating this for?

    1. Fenbendazole.org

      Hello, and thank you for a question.

      For Panacur C 4 grams, the typical medium-intensity treatment is usually 4 days on, 3 days off each week. Some people tolerate fenbendazole very well and do not experience side effects, allowing them to use it 6 days on, 1 day off without problems.

      It is important to start at a comfortable dose—often around 222 mg per day—and monitor how she responds.

      1. Zena

        thank you for responding greatly appreciated. i am curious as to how will one know it is actually working? should we go in for tests? As of now my mother’s labs are all excellent the lesions only show on the liver

        1. Fenbendazole.org

          Hello, Zena!
          Thank you for your question. If the lesions are currently visible only on the liver, the most reliable way to monitor progress would be through follow-up imaging such as MRI, CT, or PET scans, as advised by her medical team.

          In some cases, relevant blood markers may provide additional information, though not all cancers have reliable markers.

          Clinical signs such as stable energy, appetite, and overall condition can also offer supporting insight, but should not replace objective testing.

      2. Zena

        Hi Sorry again, would you help me in which Fenbendazole I can purchase and where?

  70. Sergio

    I ask for a person with pancreatic cancer, which has now gone to the liver: can fenbendazole help her? To improve absorption, can it be mixed with olive oil?
    Thank you.

    1. Fenbendazole.org

      Hello, Sergio, thank you for reaching out!

      Fenbendazole has been used by people with pancreatic cancer that has spread to the liver. It is recommended to take fenbendazole with a fatty meal or with olive oil to improve absorption, as fenbendazole is fat-soluble.

      For liver protection during treatment, supplements such as milk thistle, alpha-lipoic acid, and N-acetylcysteine (NAC) are often used to support liver health. Regular monitoring of liver function is important.

  71. Andy

    Hi there,
    I’m looking in this protocol (along with DCA & Ivermectin) for my mother (74 years old and 52 kg). She had Pancreatic cancer and underwent whipple surgery 4 weeks ago. When is generally safe to start this protocol and any side effects to watch out for? Thank you

    1. Fenbendazole.org

      Hello, Andy.
      Your mother can usually start the Fenbendazole + DCA + Ivermectin protocol 4–6 weeks after Whipple surgery, but only if her doctor agrees she is stable.
      Watch for side effects:
      Fenbendazole: stomach upset, possible liver strain
      DCA: nerve tingling, fatigue
      Ivermectin: dizziness, nausea

      Start low and monitor carefully.

      1. Nikki

        Can you tell me how people generally incorporate ivermectin?

        1. Fenbendazole.org

          Most people who use ivermectin alongside fenbendazole take it 1 to 2 times per week, usually on non-fenbendazole days. The typical dose is around 0.2 to 0.4 mg per kg of body weight, often simplified to 6–12 mg per dose for adults, depending on weight.

          It’s taken with a fatty meal to improve absorption, and some people follow a 4-week-on/1-week-off cycle or something similar.

      Hello, Michelle, thank you for a question.

      We are sorry to hear about your diagnosis. People often use Fenbendazole as a complementary therapy in conjunction with treatments such as oral chemo, CBD oil, dandelion tea, and soursop.
      A common fenbendazole regimen is 222 mg taken with a fatty meal, 3 days on and 4 days off each week. It is important to monitor liver function if possible, especially when combining multiple supplements.

  73. Andrew Johnson

    Hi
    I have been diagnosed with Primary liver cancer with multiple lesions. Basically wondering if there is any hope for me given that Fenbendazole is processed through the liver. I’ve agreed to immunotherapy but Oncologist didn’t sound hopeful.
    Thank you

    1. Fenbendazole.org

      Hello, and thank you for reaching out. It is completely understandable that you are exploring all avenues—including fenbendazole—as you navigate this challenging time.

      In individuals with liver cancer, this is an important consideration: a compromised liver may process the compound differently, which could affect both its safety and effectiveness. However, based on evidence and testimonials, some patients with liver involvement have still chosen to proceed with low doses while carefully monitoring liver function through regular blood tests.

      While fenbendazole is generally well-tolerated in off-label human use, clinical data specific to patients with primary liver cancer is lacking, so decisions should be made cautiously, ideally under the guidance of a healthcare provider who is open to integrative or complementary approaches.

  74. Alexandra and Franck Airaud

    Hello, I would like to know if there is a preferred time or meal to take my fenbendazole. My wife started taking fenbendazole today and is wondering if taking it with her evening meal is of any importance? Or is lunch more appropriate?
    My wife has four metastatic sites in her lung that have been stable for a month, in her pleura, in her liver that has become unresponsive after 30 chemotherapy sessions, and in her brain that appear to have healed following a radiation treatment. In addition to fenbendazole, do you have any advice from testimonials you could share with us, please?
    Thank you very much in advance.

    1. Fenbendazole.org

      Hello, and thank you for a question!
      Fenbendazole is typically best taken with a fatty meal, regardless of whether it’s lunch or dinner. This is because fenbendazole is fat-soluble, and fat aids in its absorption. Many users prefer taking it with dinner simply for convenience and routine, but there is no medical requirement that it must be taken in the evening—what matters most is that it’s taken consistently with food containing some fat (e.g., olive oil, avocado, nuts, or fatty fish).

  75. Mike Brown

    After a meal Will taking fenbendazole powder mixed into peanut butter more absorbant?

    1. Fenbendazole.org

      Hello, Mike. Thank you for a question.
      Yes, taking fenbendazole powder mixed into peanut butter after a meal is a good method. Peanut butter contains fat, which helps improve absorption, since fenbendazole is fat-soluble. This makes it more bioavailable compared to taking it with water or on an empty stomach.

      1. Jen

        Hi, does this method apply to a dog with liver cancer? I’m using Panacur C for her, and she’s becoming selective about her food; I know she likes peanut butter.

        1. Fenbendazole.org

          Yes peanut butter works well in this case. Liver cancer in dogs can impair appetite. This is due to the liver’s critical role in metabolism and detoxification; when compromised, it can lead to nausea, discomfort, and a general decline in well-being, all of which may reduce desire to eat.

  76. Jen Fritz

    Hi, I’m using Fenbendazole C-granules for our dog Piper, who was recently diagnosed with liver cancer. She weighs 64 pounds, and the package instructions are 2 grams + 4 grams for 60 pounds. Would this be an appropriate dose for 64 pounds? Additionally, we’ve been giving her Denamarin, milk thistle, turkey tail mushrooms, turmeric, vitamin E, omega-3, and probiotics, as well as dandelion, and we’ve changed her diet. We took her for another blood test after two weeks of taking the granules, which she takes three days on and four days off, but the blood test came back with no changes. Her ALT, AST, ALP, and GGT levels are still high. Is this because it’s too early? Also, would the granules be as effective as the Safeguard suspension for goats? I’m grateful and thankful for this website and have been sharing it with friends who might need assistance with dosing.

    1. Fenbendazole.org

      Hello, Jen.
      Thank you for your thoughtful message and care for Piper.

      Yes, using the 2 g + 4 g packet combination for a 64-pound dog is within range and acceptable—slightly over is better than under in this case. Just ensure she takes it with food to support absorption.

      The granules are equally effective as the goat suspension if dosed correctly. There is no clear advantage of one over the other—choose whichever Piper tolerates better.

      Regarding liver enzymes: two weeks is likely too early to expect noticeable changes, especially in cancer cases. Continue monitoring over a longer period. What you are giving in terms of supplements and diet is solid. Just stay consistent, watch for clinical changes, and follow up on blood work every few weeks.

      Wishing strength to you and Piper.

      1. Jen

        Thank you so much for taking the time to respond, I really appreciate it.

      2. Joe Plumeri

        My sister has pancreatitic cancer stage 4.
        I have Ivermectin, 12 mg Fenbendazole 222 mg and Menbendazole 500 mg coming.
        Should I do an aggressive 2x a day dose for 7 days ? Or something different. Im trying to save her life.

        1. Fenbendazole.org

          We fully understand the urgency of the situation. However, doubling the dose may lead to significant adverse effects, and in some cases, individuals are compelled to discontinue the protocol prematurely. We strongly advise beginning with the standard dosage to assess tolerance. If she responds well—without noticeable changes in overall health—it may then be appropriate to consider a gradual increase. Her condition, general well-being, and liver enzyme levels should be closely monitored, ideally every 1–2 months. While time is undoubtedly a critical factor, accelerating the process too quickly may compromise long-term outcomes.

  77. Sarah

    I see that after the initial parasite cleanse, cats should repeat after 1-3 months, dogs should repeat after 6 months, so how about humans? I may have missed it somewhere… how long do humans go between cleanes?
    And thank you so much for your wonderful website and for answering so many questions!! You are a God-send! <3

    1. Fenbendazole.org

      Hello, Sarah!
      Routine cleansing is typically administered interval of every 6 to 12 months, provided no contraindications exist. But in human medicine, the frequency of antiparasitic (anthelmintic) treatments depends on various factors, including the individual’s risk of re-exposure, geographic location, sanitation practices, and whether treatment is being administered prophylactically or therapeutically.

  78. Yos

    My Dad have a prostate tumor, now began to cause discomfort. Do you have any experience or story of success rate using Fenbendazole to cure this kind of tumor? Thank you.

    1. Fenbendazole.org

      Hello. Thank you for your message, and we are sorry your father is going through this.

      There are no published clinical studies that provide a specific success rate or percentage for using fenbendazole in treating prostate cancer. Most available information comes from individual reports or forums, where people have shared positive outcomes, such as reduced PSA levels, slowed tumor growth, or improved well-being, and ever reaching NED. It is hard to predict percentage of a success rate using Fenbendazole.

      Fenbendazole remains an experimental treatment in this context.

      1. Yos

        Thank you for the prompt reply. Question: What about safety usage of Fenbendazole for weak liver. Weak liver could be resulted from previous hepatitis C (cured). Or tumor grow on liver.

        1. Fenbendazole.org

          Fenbendazole is primarily processed through the liver, so in cases of past liver conditions—such as cured hepatitis C or liver tumors—caution is advised. While many people with a history of liver issues have used it without serious side effects, each case is unique.
          If the liver has been compromised, it may be wise to start with a lower dose and monitor liver function closely. Supporting liver health with supplements like milk thistle, alpha-lipoic acid, or NAC can also be helpful.

  79. DCH

    Hi, Is Fenbendazole safe to give in conjunction with (DMSO) dimethyl sulfoxide? I am treating a dog(not a human) with cancer.
    My dog has lymphoma and tumors in his liver and spleen.
    Additionally, I read your article on this here ( https://www.fenbendazole.org/what-is-fenbendazole-and-how-can-it-affect-cancer-treatment/ ) as well as the article about the study that is posted on the nih’s website. ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2687140/ )
    And I have my dog on the vitamins that the mice were given, and I based the amounts on the “% increase” section from “Table 1” from the page about the study on the nih’s website, and found the correct daily intake of vitamins for a dog of my dog’s weight for each vitamin, and just adjusted the daily % by the “% increase” from “Table 1”.
    I wanted to check if I understood this correctly and took the correct course of action.
    5 1/2 weeks ago, after an ultrasound, the vet said he had a few days to live, 2 weeks max.
    The day after his vet visit, I found Fenben and have started him on his treatment. He’s been doing good most days, but the past 6 or so days he’s had a few rough days, where he hasn’t looked like he was feeling good, and today he fell to his side, like he would if he was feinting, but he didn’t feint. I don’t know for sure what caused it, perhaps weakness. He did have some diarrhea and wasn’t hungry enough to eat dinner for the first time in the 5 1/2 weeks since we started his treatment.
    We had him ultrasounded again 1 1/2 weeks ago, and the tumors in his liver and spleen had not grown, but the vet said if they had shrunk, it would only be by a very small amount.
    I wanted to know what I could be doing wrong. I am giving him fenben 6 days on 1 day off most of the time, with 2 of the 5 1/2 we did 7 days a week. He has 1 of the 3 lobes of his liver taken up by a tumor, but as of 1 1/2 weeks ago, hasn’t spread.
    I did see on the dosage page that it could take 3-6 weeks for fenben to really start working, so I don’t know if that’s the cause, or if this has something to do with the liver being where fenben is processed. I’ve read almost everything I could find about fenben and educated myself the best I could in the time I have, but after seeing my dog fall over today, I am worried I am either not doing enough or doing something wrong, and I am reaching out for help and advice.
    Thank you so much for this website. Without fenben my dog would’ve likely passed away 5 weeks ago. If nothing else, you’ve helped me have more time with my best friend, so I don’t have to say goodbye yet. I would like to delay that final goodbye a lot longer, if possible. Thank you.

      Hello! Thank you for your message and for the care you are giving your dog—it is clear how deeply you care.

      Fenbendazole and DMSO do not have any confirmed harmful interaction, but DMSO increases absorption of other substances. This could place additional stress on the liver, especially since your dog has a large tumor in one of the liver lobes. If you continue using DMSO, use it in low concentration and monitor closely for side effects.

      Your protocol based on the NIH study and adjusted by weight sounds very thoughtful. The fact that tumors have not grown is encouraging. The recent weakness, fall, and loss of appetite may reflect liver strain, general fatigue, or tumor-related changes. It may help to give his system a short break (1–2 days off everything) to see if he rebounds.

      You are doing a lot right. We hope you continue to have more time with him. Please feel free to reach out again

    2. Michele Dotson

      Try Ivermectin with your Fenben. I’ve been researching and that combo is curing cancer. 🙏❤️

        Good evening my friends, question, if you are 230 lb the recommended dose is 444 mg, and then if I’m 198 then the milligrams come down to 222. I was wondering that if I get down to 198 can I still take the 444 mg of Fenbendazole? And also I was wondering instead of taking the milk thistle that you recommended would it be okay to take an active charcoal? Thank you for your time and thank you for helping so many people, because I tell you the doctors I believe they don’t care anymore, they just go through protocol. At least that’s what I see. Again thank you for your time everybody here appreciates you. God bless.

    Hello. I have been diagnosed with Multinodular non toxic goiter. I have thyroid nodules on both lobes. The FNA established a category IV Follicular Neoplasm (the standard rates being 30% malign – 70% benign). Due to the size of one of the nodules and due to the nodules being present in both lobes, medics recommended total thyroidectomy after which the histopathology report will determine the exact nature of the neoplasm. Before choosing surgery I would like to try the Fenben + supplements, perhaps it will save me the surgery. I am currently taking 444mg ( aligned with my kg) of Fenben Mon/Wed/Fri with daily supplements : Vitamin D (as I was severely deficient back when I first went to see the doctor), Zinc (also deficient), K2 (for Vitamin D), Curcumin, Black Cumin, Omega 3, CoQ10, EGCG, Magnesium and Tudca (for Fenben). I chose the supplements with the help of Grok. The stack stopped the growth for now. My next ultrasound check is in May to assess any further changes. Should I continue the 444mg Mon/Wed/Fri or should I change this? Do you have any other recommendations?

    1. Fenbendazole.org

      Hello and thank you for Your message. Given that your current fenbendazole protocol (444 mg on Mon/Wed/Fri) appears to have stabilized the nodules, it is reasonable to continue with it until your ultrasound in May, as long as you feel well and tolerate it.

      Your supplement stack is well-chosen and supports immune, liver, and metabolic health. Just ensure you are monitoring thyroid function and liver enzymes from time to time.

      No changes are urgently needed. Staying the course until your next scan is a sound approach.

    2. Kristine

      Keep us updated. I am treating nodules on both sides-benign but causing vocal issues.

  81. Frank Bowman

    Hi guys Frank here again, I got a question? now as you know, as I stated in my last questionnaire that I had stage 4 cancer that I’m dealing with that in the knee and in the kidneys. I was just wondering cuz you were saying that I would have to double it the dose twice a day to get the 444 mg and that if I was 198 lb then I would only have to take 222 mg,. My question is would it be all right to take Fenbendazole, twice a day, for 4 days and then fast for three and then after the third day of fasting start up on it again? I’m trying to lose the weight so I can get down to 198 lb, actually I’m trying to get down to 180. And I wanted your thought on that still taking the curcumin twice a day with the CBD oil before bed. also I’mwatching what I eat, throughout all the junk food, having my green tea, my soursop tea and my moringa tea. And also have my vitamins, D3, B complex, magnesium and fish oil. Just wanted your opinion thank you I really appreciate your time and your thoughts. Thank you again Frank Bowman

    1. Fenbendazole.org

      Hello Frank,

      Thank you for your message—your dedication to your health is clear and commendable. Overall, your approach looks solid: the fenbendazole schedule, curcumin and CBD routine, healthy teas, and supportive supplements are all in line with integrative strategies many find helpful.

      The only note we would add is regarding the fasting. While fasting can promote processes like autophagy and may have metabolic and immune benefits, prolonged or aggressive fasting—especially in the context of cancer—can sometimes place extra stress on the body. Some research suggests that shorter fasts (such as 12–16 hours) or intermittent fasting may provide benefits without compromising strength or nutrition, particularly when the body is already under strain.

      That said, this is a personal decision. If fasting feels right for you and you are monitoring your well-being closely, it can be part of your regimen. Just be kind to your body along the way, and make adjustments as needed.

      Wishing you steady strength and clarity on your path forward.

  82. Frank Bowman

    How many times am I supposed to take the fenbendazole? On Joe Tipton’s protocol it says take one but when a calculus is 444 mg, so does that mean I got a ticket twice a day? Because instead of ordering the 2 g I could have got the 4 g. Just wondering please help me out, dealing with cancer in my knee and in my kidneys.

    1. Fenbendazole.org

      Dear Frank,
      Thank you for your question, and I am truly sorry to hear what you are going through. The standard fenbendazole dose for cancer support is generally based on body weight. For most adults, the typical dose is 222 milligrams per day if the person weighs under 90 kilograms (198 pounds), and 444 milligrams per day if the person weighs more than that. So if your capsules are 444 milligrams and you weigh over 90 kilograms, then taking one capsule per day is correct — there is no need to take it twice daily. Most people take it once a day with food that contains some fat, which helps with absorption, and follow a schedule of six days on and one day off.

  83. William

    Wondering if you’re calculator is broken. Says 222mg for a 5 lb cat and 222mg for a 150lb human

    1. Fenbendazole.org

      Hello, William!
      Thank you for a wonderful observation. Cats are pure carnivores, so they have much shorter digestive tracts, and much less fenbendazole is absorbed. Cats usually get 50 mg/kg at veterinary dehelmintization cases, so for a 5 lb cat (about 2.27 kg): At 50 mg/kg, the correct dose would be be:2.27 kg × 50 mg = ~113 mg/day. In cancer cases, the dose is usually higher, so 222 mg is approximately the correct calculation.

  84. Roberto

    Hello i have a question for a very concerned friend.

    She is just diagnosed with leukemia.
    Does she need to do the Fenbendazole protocol or mixed with ivermectin?
    Can you use the pasta or the pills from the vet?
    How much percentage does the pill or pasta need to contain?
    I am hesitating because i also found capsules with 99% Fenben for example.
    So know i don’t know if you can use them from the vet.

    I hope you can help me out.

    Thanks a lot.

    I wish everybody the best. Never give up

    Greetings,

    Roberto

    1. Fenbendazole.org

      Hello, Roberto.
      Yes, you can choose from veterinary-grade fenbendazole designed for animals, or you can buy just a pure compound online. Veterinary products usually have 10-20% of fenbendazole in a product—the other half is binders and fillers for smell, absorption, and taste. We do not consult as much on ivermectin, but yes, lots of people use ivermectin and fenbendazole in combination. We must address, though, that ivermectin is a much more sensitive compound and can cause more side effects like dizziness, headache, “brain fog,” and others. Use at your discretion.

  85. Alex

    hi. Tell me how to take fenbendazole in combination with invermectin for multiple myeloma. And is it possible to take these preparations for kidney problems if a person is undergoing hemodialysis?

    1. Fenbendazole.org

      Hello, Alex, thank you for a question.
      There are some heightened risks when taking fenbendazole and ivermectin while undergoing dialysis:
      Impaired drug clearance can accumulate toxic metabolites.
      Dialysis patients often take many other meds — interaction risk is high.
      Liver function may also be impaired in advanced kidney disease, affecting both drugs.
      Some dialysis patients have a weakened blood-brain barrier, increasing the risk of neurological side effects (especially with ivermectin).

  86. Erika

    Hello,
    Thank you for this excellent resource!

    If I suspect my cat has cancer (5.5 kg) due to borderline low anemia and unexplained weightloss (if not due to stress of a new cat in the house), should I still do the outlined cancer protocol (333 mg, 4 days on, 3 days off)? And if so, for how long?

    His other labs are good, but anemia is tricky in cats.

    I have milk thistle and curcumin as well.

    Is there anything else you’d recommend at this time?

    Thank you so much!!

    1. Fenbendazole.org

      Hello, Erika!
      First of all, we would like to inform you that low anemia and weight loss can signal a lot of different plausible illnesses, so a more thorough vet evaluation is needed because these symptoms can be signaling:
      Chronic kidney disease (CKD)
      Hyperthyroidism (usually causes weight loss without anemia)
      Chronic infections (FIV, FeLV, FIP)
      Inflammatory bowel disease (IBD) (sometimes overlaps with lymphoma)
      Also, this could be: Multiple Myeloma (Plasma Cell Tumor), Hemangiosarcoma or Other Bleeding Tumors, Leukemia (especially FeLV-associated), Intestinal Adenocarcinoma or Other GI Tumors, Lymphoma.
      Now talking about supplements for your cat if he is taking fenben would be: milk thistle, dandelion root, turmeric, SAMe (S-Adenosylmethionine).

  87. Augustus

    Hello, thank you for your work and your availability,
    I’m contacting you because our cat was operated on in April 2024 for two simple mammary carcinomas, grade 2 or even 3.
    Here we are 1 year later, in April 2025, lumps have reappeared, including a “ball” almost the size of a golf ball under the armpit.
    We decided to use fenbendazole. I therefore have a few questions.

    For a dose of 444mg, can the fenbendazole tablet be broken in 2 to give 1 half in the morning and the other half in the afternoon?
    Can the tablet halves be ground into powder and mixed with the food?
    Should our cat take a supplement to help his liver?
    Also, I’d like to know what to watch out for when our cat takes blood tests (ephatic function, renal system? I don’t know), and how often he should take blood tests?

    I am aware that this is a lot of questions, I apologize in advance.
    Thank you very much.

    1. Fenbendazole.org

      Hello, Augustus. Thank you for a question.
      We are really sorry to hear about your cat’s recurrence. Mammary carcinomas in cats can be aggressive, especially if they’re grade 2–3, so your concern is completely valid.
      Yes, tablets can be divided in 2 to give 1 half in the morning and the other half later. Also, you can grind it into powder, and some pet owners do just that because it is easier to feed it that way. Mix with food, because fenbendazole does not dissolve in water but in fat, so mixing with food is a great idea.
      Supplements for liver health are a great idea; ask your veterinarian for top-quality broad-spectrum vitamins and liver supplements.

      Blood Tests: What to Watch For:
      When dealing with cancer and especially recurrence, the bloodwork serves two main purposes:

      Assess overall health (especially before/while on treatment)
      Detect complications or organ strain

      Key Parameters to Monitor
      Kidney function:
      Creatinine & BUN (blood urea nitrogen) – check for early signs of kidney stress/failure.
      SDMA – a more sensitive kidney marker, often included in more comprehensive panels.

      Liver function:
      ALT, AST, ALP, GGT – liver enzymes can indicate if the liver is inflamed or compromised.
      Bilirubin – high levels can suggest liver or bile duct issues.

      CBC (Complete Blood Count):

      White blood cells – can indicate infection, inflammation, or immune suppression.
      Red blood cells & hematocrit – to monitor for anemia (common in chronic disease).

      Platelets – needed to assess clotting ability, especially before any procedure.

      Thyroid (T4) – if the cat is older, this is often included to rule out hyperthyroidism, which can mask weight loss due to cancer.

      1. Augustus

        We are very grateful for your reply. We are going to start giving him Fenbendazole.
        Also, for a few months we’ve been giving him CDS (Chlorine Dioxide): 2 drops of sodium chlorite 25% in 100ml of water.
        Is it all right to continue giving him this at the same time as the fenbendazole?

        1. Fenbendazole.org

          Thank you for your message — it is clear how much you care for your cat.
          Regarding the use of Fenbendazole together with CDS (Chlorine Dioxide), there are no well-documented interactions between the two, but there are also no specific studies confirming their combined safety in animals. If you choose to use both, it is best to space them out by a few hours — for example, Fenbendazole with food in the morning and CDS later in the day. This helps reduce any chance of digestive irritation or unexpected interaction.
          Keep a close eye on your cat for any signs of vomiting, diarrhea, appetite changes, or unusual behavior. If anything seems off, stop one of the treatments and consult your vet. Since both substances may affect the liver or kidneys, regular bloodwork is recommended. Ideally, work with a veterinarian open to supportive or integrative approaches.
          Wishing you and your cat strength and healing.

  88. Adel Khalifa

    Hi! Stage 4 HCC mets to the bones. On sorafenib 800mg. Compensated cirrhotic liver. Child-Pugh class A5.

    I only have access to Mebendazole and Ivermectin. Is FBD dose directly translated to MBD dose? I mean should I take 200mg of MBD? If that so, since I’m on sorafenib should I take a lower dose of MBD or FBD?

    1. Fenbendazole.org

      Dear Adel,
      Given your current situation—it is completely understandable that you are seeking effective and supportive therapies.
      Mebendazole and fenbendazole are related compounds, but they are not dosed identically. Mebendazole has a different absorption profile and has been studied in cancer settings at significantly higher doses than those typically used for parasitic infections.
      In cancer-related use, mebendazole is often administered at 300 to 500 mg per day, split into two or three doses. Some clinical settings have used doses as high as 1.5 g/day safely, though that may not be appropriate in your case due to the presence of liver disease and concurrent medication.
      Given your liver status, a more cautious approach is advisable. A commonly considered starting point is 100 mg twice daily (200 mg total/day), with careful observation for side effects. This may later be increased based on tolerance and therapeutic response. Please avoid assuming that 200 mg per day is a full-dose anticancer protocol—it is often too low for this purpose unless there are specific concerns about liver function or drug interactions.
      Regarding your use of Ivermectin alongside MBD: this combination is being explored in alternative and off-label protocols for its potential anticancer synergy. It is generally considered safe in combination when taken at appropriate doses, such as 0.2 mg/kg four or five times a week, though always with awareness of individual tolerance and possible interactions.

  89. Zachary

    Hi,

    I am 130lbs. and trying to get rid of roundworm (Ascaris lumbricoides) parasites in my intestinal tract. Based on the dosage calculator it indicates that I should take 222mg, but there is a discrepancy on how many days in a row one should take FenBen at this dosage. Is it 3, 4, or 5 days in a row? Repeating at 3 weeks seems to be the standard protocol. Thank you!

    1. Fenbendazole.org

      Dear Zachary,
      Thanks for your question! According to the standard protocol, Fenbendazole should be taken at a dose of 222 mg once a day for 5 days in a row. This cycle is usually repeated after 3 weeks to target any worms that may have hatched from eggs after the first round. So yes — 5 consecutive days is the recommended duration for one treatment cycle.
      Also, for better absorption, Fenbendazole should be taken with or right after a meal, ideally something with fat. Many people mix it with foods like yogurt, avocado toast, or even sprinkle it on their meals. Just let it sit for a few minutes so the fats can help with absorption.

  90. Ralph B

    Hi,
    Next question, female old English bulldog with liver carcinoma, anal gland carcinoma and metastases in lymph nodes, rib cage and mouth.
    Did a liver check on week 8 and liver function was better, from 70 to 75%….great!
    So I went from 444mg to 500mg on week 9. 4 days on, 3 days off.
    Now in week 11 of treatment, it does not appear to be responding in the osteosarcoma of the rib cage, but the lymph nodes and the oral tumor do not seem to be growing anymore.
    The osteosarcoma on the rib cage continues to grow, and now I am starting to worry.
    The tumor has grown 13 cm in 11 weeks.
    Is the dosage not right, or maybe mebendazole?
    Or am I too impatient?
    Thank you again!

    1. Fenbendazole.org

      Hello Ralph,
      To better assess the fenbendazole dose, could you please confirm your dog’s current weight? Dose accuracy is crucial, especially when dealing with aggressive tumors like osteosarcoma. You can use this official dosage calculator to ensure your dog is getting the correct amount based on weight:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide
      If the current dose is already correct, and there is still progression in the rib cage tumor, it might be helpful to consider adding ivermectin to the protocol. Ivermectin is sometimes used for its potential anti-tumor and immune-modulating effects, and it has been well tolerated by many dogs when dosed properly (usually 0.2 mg/kg once or twice weekly).
      You could also explore Mebendazole as an alternative, especially if the response to fenbendazole plateaus. Mebendazole may have a slightly different activity profile and is sometimes preferred for certain cancers.
      Finally, it is worth noting that some tumors respond more slowly than others. While 11 weeks can feel long, continued monitoring is key. You may also want to consult your veterinarian regarding any other integrative options and how to safely combine them.

      1. Ralph B

        The dog’s weight is now 30.5 Kg.
        Went down from 34kg in 4 months.

        1. Fenbendazole.org

          Hello, Ralph, and thank you for this comment.
          Possible Causes of Weight Loss:
          Tumor Metabolism—Cancer cells consume a lot of energy, leading to muscle wasting (cachexia).
          Decreased Appetite—Some tumors cause nausea, pain, or a loss of appetite.
          Nutrient Absorption Issues—If cancer affects the digestive tract, the dog might not absorb nutrients properly.
          Inflammation & Immune Response—The body’s fight against cancer can increase metabolic demands, leading to weight loss.

          If the dog is eating well but still losing weight, it’s likely cancer-related.

          If the dog is not eating much, vomiting, or having diarrhea, fenben could be a factor, but it would usually be mild.

          If weight loss is rapid and muscle is wasting, it might be cachexia from cancer progression.

          1. Ralph B

            Thank you for the swift response!
            Our dog eats really well, is happy, and doesn’t have any pain.
            What is the best dosage of mebendazole for a dog weighing 30.5 kg, the same as fenbendazole? Four days on and three days off?
            Started today with ivermectin!
            Thanks a lot and keep up the good work!

          2. Fenbendazole.org

            Thank you for your kind message, and we are truly glad to hear that your dog is eating well, appears happy, and is not experiencing any pain.
            Regarding your question about Mebendazole dosing for a dog weighing 30.5 kilograms: while there is no universally standardized protocol for Mebendazole in off-label use for dogs, a commonly referenced dosage in similar contexts is approximately 5 to 10 mg per kilogram of body weight per day. For a 30.5 kg dog, this would translate to a daily dose of approximately 150 to 300 mg of Mebendazole. Most individuals choose to begin on the lower end of the range and monitor closely for tolerance and response.
            You may follow a similar schedule as with Fenbendazole, such as four days on and three days off, although some opt for a continuous schedule depending on the goal and the dog’s condition. Always ensure that any dosing schedule is monitored closely for any signs of gastrointestinal upset or changes in behavior.
            It is excellent that you have initiated Ivermectin as well. Please remember to provide adequate hydration and consider adding liver support supplements such as milk thistle or TUDCA, especially when using multiple compounds.

  91. Bob & Pat

    I’d like to see a video showing how much paste one would dispense on a spoon for an average weight human. Do the various brands have different amounts of Fenbendazole in them?

    1. Fenbendazole.org

      Hello Bob & Pat,
      When using Fenbendazole in paste form, the amount dispensed onto a spoon will depend on the concentration of the specific product being used. Yes, different brands can indeed contain varying amounts of Fenbendazole per unit of volume, so it is very important to check the label for the exact concentration—usually expressed as milligrams per gram (mg/g) or per milliliter (mg/ml).
      For example, a common paste may contain 100 mg of Fenbendazole per gram. In this case, if a person is aiming for a 222 mg dose (a frequently referenced amount for adult use), they would need approximately 2.2 grams of paste. However, this calculation only applies if the paste is precisely 100 mg/g. If the concentration is different, the required amount would need to be adjusted accordingly.
      Because of these differences, I recommend checking the product packaging or contacting the manufacturer directly to confirm the exact concentration of Fenbendazole in the specific paste you are using.

  92. Amy

    My husband has been diagnosed with Polycenthemia Vera please share protocol for this. Your help in this matter is greatly appreciated.

    1. Fenbendazole.org

      Hello Amy,
      Thank you for reaching out. While there is no official protocol specifically tailored to Polycythemia Vera, some individuals have explored off-label use of compounds like Fenbendazole. On our site, you will find a dosage calculator designed to help determine the appropriate amount of Fenbendazole based on body weight: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Just below the calculator, we also provide a full suggested protocol, including schedule, dosing strategy (commonly 6 days on, 1 day off), and tips on how to support the body during use—such as adding supplements like milk thistle for liver support and curcumin for its synergistic effects.

  93. Carol

    Hi,
    Thank you for this website! My husband has been doing oxygen therapy (h2o2 drops). It works, but puts a lot of pressure on his kidneys when the tumour markers are dropping rapidly. Thus we want to know if he can try and add the fenbendazole protocol while also taking the maintenance dose of the h2o2 drops (3 drops x 3 times daily).
    Thanks

    1. Fenbendazole.org

      Hi,
      Thank you for your message and for sharing the details of your husband’s protocol. Yes, Fenbendazole can generally be used alongside a maintenance dose of hydrogen peroxide drops, as they support the body in different ways. Since both may place some strain on the kidneys or liver, it’s important to stay well hydrated and consider adding support like milk thistle or TUDCA. The typical Fenbendazole schedule is 222 mg daily, six days on and one day off. If any side effects occur, the dose can be adjusted. Always monitor how he feels and proceed gradually. Wishing you both strength on this path.

  94. Merve

    Hi, my father recently underwent surgery for pancreatic cancer (adenocarcinoma, late stage 2 to early stage 3) and had a Whipple procedure. However, it is uncertain whether an R0-resection was achieved, so we cannot rule out the presence of residual cancer cells. He also has heart disease and is taking statins, beta-blockers, and blood thinners. I want to rule out metastasis and eliminate any remaining cancer cells. Would it be safe for him to take 444 mg of fenbendazole daily, or should he start with a lower dose of 222 mg per day, with a one-day break in between, to ensure safety? I would greatly appreciate a quick response, as this is very urgent.

    1. Fenbendazole.org

      Hello, Merve and thank you for a question.
      It is always a good idea to start slow and take a safer approach. He will get to 444 mg eventually. Breaks are also a great idea and should be done regardless. Also consider supplements for liver enzymes like milk thistle, alpha-lipoic acid, and TUDCA-curcumin.

  95. Kitty Sawyer

    I want to start a parasite cleanse and have been told to take fenbendazole and ivermectin. Do I need both and if so what is the protocol?

    1. Fenbendazole.org

      Dear Kitty,
      Fenbendazole and Ivermectin can be used together for a broader-spectrum parasite cleanse, as they target different types of parasites. Fenbendazole is effective against intestinal parasites, while Ivermectin works more on tissue and blood parasites.
      A typical Fenbendazole protocol is 222 mg per day, taken with food, five days on and two days off. You can repeat this cycle for several weeks. To determine the exact dose based on body weight, you can use this calculator: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide
      Ivermectin is usually taken at 0.2 mg per kg of body weight, once or twice a week, on an empty stomach.
      During the cleanse, staying well-hydrated and supporting the liver with supplements like milk thistle or TUDCA is often recommended. If any side effects arise, it may be helpful to temporarily reduce the dosage.

  96. Alex

    Hello, I’m having a hard time calculating the dosage for around a 9.6 lb dog? Using the 100mg liquid? Also are there any liquid supplements that would help along with the fenbendazole? She has oral melanoma

    1. Fenbendazole.org

      Dear Alex,
      For a 9.6 lb (4.35 kg) dog diagnosed with oral melanoma, the recommended fenbendazole dosage is 222 mg administered once daily for four consecutive days, followed by a three-day break. This cycle should be repeated weekly. Given that the liquid formulation contains 100 mg per milliliter, the appropriate volume to administer is 2.22 milliliters per dose. In addition to fenbendazole, certain adjunctive supplements may provide complementary support. Curcumin has been studied for its potential anti-inflammatory and pro-apoptotic effects. Omega-3 fatty acids, particularly from fish oil, may contribute to anti-inflammatory pathways and could be beneficial in oncology protocols. Polysaccharopeptides found in turkey tail mushrooms have been researched for their immunomodulatory properties, particularly in supporting natural killer cell activity. Cannabidiol has been investigated for its potential role in modulating inflammatory responses and supporting quality of life in animals with cancer. Monitoring for any adverse reactions or changes in the clinical condition is essential when incorporating any therapeutic agents. It is advisable to ensure that any additional supplements do not interfere with ongoing treatments and are appropriate for the specific health status of the animal.

        Hi again,

        The bottle I got is for goats. It says 25 lbs equals 0.6 mL. Therefore, shouldn’t the dose be 0.2 or 0.22 mL?
        Thanks

        1. Fenbendazole.org

          Dear Alex,
          Thank you for your question. The dosage instructions on your bottle are intended for goats and are based on their weight, but when using fenbendazole for personal use, the calculation needs to be adjusted based on the concentration of the active ingredient in the suspension and the intended human dose.
          Most commonly, people take either 222 mg or 444 mg of fenbendazole per day, depending on body weight. The standard dose is 222 mg daily for individuals under 90 kg (198 lbs) and 444 mg daily for those over that weight.
          If your goat suspension states that 0.6 mL is used per 25 lbs, you first need to confirm how much fenbendazole (in mg) is contained per 1 mL of the liquid. This information is usually printed on the label (for example, it may say “100 mg/mL”).
          Once you know the concentration, you can calculate the exact volume needed to get the desired human dose. For example:
          – If the suspension contains 100 mg/mL, then a 222 mg dose equals 2.22 mL.
          – A 444 mg dose would then be 4.44 mL.
          So, the dose is not necessarily 0.2 or 0.22 mL unless the product is extremely concentrated. It is important to calculate based on the mg per mL, not just the veterinary instructions for animals.
          If you are unsure, you can use the dosage calculator found here to help determine the correct dose: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/

          1. Alex

            The dose is for a 9.6 lb dog. And it’s a 100 mg/ml concentration. So shouldn’t it be 0.22 ML?
            Unfortunately the calculator doesn’t work.
            Thanks again, Alex

          2. Alex

            Hello again,
            I’m sorry to keep asking, but I’m getting contradicting dosages at different websites.
            The fenben is a 10% suspension, 100 mg/mL liquid for goats, which states for 25 lbs it would be 0.6 mL.
            Now I would be using it on a 9.6 lbs pomeranian, so using the goat chart amount, it would be 0.22mL.
            But using the calculator on here indicates the dosage as 2.22 mL.
            So the differing amounts is concerning as I dont want to accidentally give too much to my dog.
            Is it just that the amount given for cancer is more? As opposed to just as a dewormer?

            Thanks again, Alex

          3. Fenbendazole.org

            Hello, Alex!
            You’re absolutely right to double-check the dosage. The discrepancy comes from the difference between the standard deworming dose and the higher doses sometimes used in alternative protocols for cancer.

            Standard Deworming Dose:
            For goats, the typical dosage is 5 mg per kg (2.27 mg per lb) of body weight.
            At 10% (100 mg/mL) concentration:

            A 9.6 lb dog would need 0.22 mL, which matches the goat dosage.

            Alternative Cancer Protocol Dose:
            The commonly referenced dose for cancer use in dogs is around 50 mg per kg (22.7 mg per lb) of body weight.

            At 10% (100 mg/mL) concentration:

            9.6 lb × 22.7 mg/lb = 218 mg

            218 mg ÷ 100 mg/mL = 2.18 mL (which is close to what the calculator gave you).

            So, yes—the cancer protocol dose is significantly higher than the deworming dose.

      2. Linda Edwards

        Can you provide information about fenben and lymphoma on the neck which developed after a dental infection? Thank you

        1. Fenbendazole.org

          Hello Linda,
          Thank you for your question. Fenbendazole is an antiparasitic drug commonly used in veterinary medicine, but in recent years it has gained attention for its potential anti-cancer properties. It works by disrupting microtubule structures within cells — a mechanism similar to certain chemotherapy drugs — which may interfere with cancer cell division and tumor growth.
          In the case of lymphoma in the neck following a dental infection, it is recognized that chronic inflammation may create conditions favorable for cancer development. While fenbendazole is not formally approved for the treatment of lymphoma, its mechanism of action and emerging studies suggest it could offer supportive benefits as part of a broader, integrative approach.
          If you are considering fenbendazole, it may be most helpful to include it in a comprehensive, well-monitored plan. Many people emphasize the importance of hydration, supporting detox pathways, and starting with low doses when beginning. Wishing you strength, clarity, and continued support on your path forward.

  97. Louis

    Hello. Our cat had a surgery to remove mammary carcinoma. Do you think Fenbendazole will work great in combination with metronomic cyclophosphamide ? There are no oncologists in the country to ask. And we read that curcumin might interfere with cyclophosphamide. She will also start Rapamycin for her hcm. Any tips are welcome please

    1. Fenbendazole.org

      Hello Louis,
      Fenbendazole has gained interest as an adjunct therapy in cancer treatment due to its potential effects on microtubule inhibition and metabolic disruption in cancer cells. While formal veterinary studies on its efficacy in feline mammary carcinoma are lacking, reports and some preclinical data suggest it may complement standard therapies. Metronomic cyclophosphamide, which involves low-dose continuous administration, is commonly used to inhibit angiogenesis and modulate the immune response in various cancers. There is no known direct contraindication between fenbendazole and metronomic cyclophosphamide, but due to fenbendazole’s impact on tubulin polymerization, monitoring for any additive toxicities is advisable. Curcumin has been reported to interfere with cyclophosphamide by potentially reducing its cytotoxic effects through antioxidant activity, particularly in some cancer models, though the extent of this interaction in feline oncology is not well-documented. If curcumin is considered, it may be beneficial to administer it at a different time from cyclophosphamide and to use a formulation with controlled bioavailability. Rapamycin, an mTOR inhibitor, has demonstrated potential in oncology and cardiac conditions such as hypertrophic cardiomyopathy, and its immunomodulatory effects could theoretically enhance the response to metronomic chemotherapy. However, given its impact on metabolic pathways and immune function, careful monitoring is necessary when used in combination with other metabolic disruptors. Since veterinary oncologists are unavailable in your region, it may be beneficial to document the response to treatment, monitor for potential adverse effects, and consider periodic bloodwork to assess liver and kidney function, immune parameters, and overall treatment tolerability.

  98. Angus

    I am currently taking FBDZ for liver cancer. I also have cirrhosis (compensated) of the liver. Is it safe for me to take fenbendazole and if so, should I reduce dosage for safety of liver? Thanks.

    1. Fenbendazole.org

      Hello Angus,
      Fenbendazole is metabolized in the liver, but there are no known reports of it causing liver toxicity at standard doses. Since you have compensated cirrhosis, it is generally advisable to monitor liver function markers such as ALT, AST, and bilirubin while taking Fenbendazole. If liver enzymes remain stable, the standard dose of 222 mg per day, six days on and one day off, is usually well tolerated. If there are concerns, starting at a lower dose and gradually increasing may be an option.
      For additional liver support, TUDCA (Tauroursodeoxycholic Acid) is highly recommended, as it helps protect liver cells, supports bile flow, and may reduce oxidative stress.

  99. Eileen

    Hi Joe, my father has stage 4 colon cancer which already spread into the liver. He has had 2 surgeries where they removed half of his liver but metastases seem to spread. He has had 2 rounds of chemo too. What protocol would be good for him? Do you think fenben is enough or should we also try Ivermectin? Any help is much appreciated!

    1. Fenbendazole.org

      Hello Eileen,
      For stage 4 colon cancer with liver metastases, Fenbendazole may be beneficial, but combining it with Ivermectin could enhance its effects. Fenbendazole disrupts microtubules, while Ivermectin inhibits WNT/β-catenin signaling, which is often involved in colon cancer progression. To ensure the correct Fenbendazole dosage, I recommend checking the dosage calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/. Ivermectin is typically dosed at 0.2 mg/kg, taken 3–4 days per week. Additionally, Milk Thistle (Silymarin) can support liver function and detoxification, which may be helpful given your father’s prior surgeries and chemotherapy. Some protocols also include curcumin, vitamin D, and NAC to help manage inflammation and oxidative stress. Since he has undergone significant treatment, monitoring liver function and inflammatory markers while introducing these additions is recommended. Let me know if you need further details.

  100. David

    Are you aware of any protocols using fenben for multiple myeloma? Since the aberrant plasma cells produce m-spike and free kappa light chains, how long might it take to affect plasma cell microtubules to effect a die-off AND then notice a decrease in blood levels of these markers? The lab question is probably my most urgent question as of right now. I took one 222 mg dose of safe-guard in the past day to start it off. I’m looking for protocols that can be used alongside immunotherapy without chemo.
    – Does fenben make it into the bone marrow?
    – Can you elaborate on the anti-inflammatory qualities of fenben? I’ve read that the increase of fractures is in part related to interleukin-6. Do you know if fenben affects IL-6?
    Thanks!

    1. Fenbendazole.org

      Dear David,
      There is no established protocol for using Fenbendazole in multiple myeloma, but it may act as a microtubule destabilizer, potentially impairing plasma cell survival. Microtubule disruption could begin within 24–72 hours, but noticeable reductions in M-spike or free light chains may take weeks to months due to immune clearance and protein turnover. While Fenbendazole is metabolized in the liver and does not preferentially accumulate in bone marrow, its active metabolites reach systemic circulation, so indirect effects on plasma cells are possible over time. Regarding inflammation, Fenbendazole inhibits NF-κB, which regulates IL-6, a key driver of plasma cell proliferation and bone loss in multiple myeloma. By modulating NF-κB, it may reduce IL-6 levels, potentially mitigating osteolysis and fracture risk, though this has not been clinically confirmed. Since you are considering Fenbendazole alongside immunotherapy rather than chemotherapy, its interactions with monoclonal antibodies like Daratumumab remain unstudied, so monitoring disease markers, bone turnover indicators, and inflammatory cytokines is recommended.
      Let me know if you have any further questions.

  101. Douglas

    Hello … I was diagnosed with stage 4 prostate cancer three years ago. I am now 71 years of age, weigh 185lbs and otherwise in good health. My oncologist has me taking 1000 mg of Abiraterone daily and also 5 mg of Prednisone twice daily. I have acquired Fenbendazole liquid, suspension 10% (100mg/ml). Is there any known contraindication when using these together? I do also take vitamin D3 with K2 daily and also Maitake mushroom powder once daily in morning coffee. Please advise me regarding a recognized protocol (dosing for the liquid). Packaging states approx. 3 – 3.5 ml daily. Maybe I should acquire tablets instead of liquid, or is the liquid OK? Thanks in advance!

    1. Fenbendazole.org

      Hello, Douglas! Thank you for a question.
      There’s no direct evidence that fenbendazole interacts negatively with abiraterone or prednisone, but potential CYP3A4 interactions and liver stress should be considered. Tablets or liquid make no real-life difference. Also, we recommend some supplements for liver health: milk thistle, curcumin, and alpha-lipoic acid.

      1. Douglas

        Thank you . . . Can you please provide recognized or customary oral dosages for the liquid in ml? I will research the CYP3A4 and act accordingly. Thanks again!!

        1. Fenbendazole.org

          Hello Douglas,
          For liquid Fenbendazole suspensions, the dosage depends on the concentration of the formulation. The most common liquid Fenbendazole products are 10 percent suspensions containing 100 mg per ml, but always check the label to confirm the exact concentration. For a standard 222 mg oral dose, the approximate volume would be 2.22 ml if using a 10 percent suspension or 4.44 ml if using a 5 percent suspension. If you are using a different concentration, you can calculate the volume by dividing the desired dose in mg by the concentration in mg per ml. Since you are researching CYP3A4 metabolism, it is worth noting that Fenbendazole undergoes hepatic metabolism primarily through CYP450 enzymes, with CYP3A4 playing a role in drug interactions. If combining with medications that inhibit or induce CYP3A4, monitoring for any changes in effects may be advisable. Let me know if you need further clarification.

  102. Ralph B

    Hello,

    Seven weeks ago, i started up the Fenben protocol for my 13-year-old dog with various cancer.
    444 mg panacur 4 days on and 3 days off with cbd oil and supportive supplements (samylin) for the liver.
    Its a female old English bulldog with liver carcinoma, anal gland carcinoma and metastases in lymph nodes, rib cage and mouth.
    Anal gland was removed, may 2024, but my dog suffered from the anesthesia afterward.
    Liver carcinoma is not an aggressive form of cancer, checked with ultrasound and puncture.
    Seven weeks ago, the liver value was also checked, and the liver function was 70%.
    Which protocol should I follow if the liver values become too bad?
    I am very happy with your website and experiences, thank you!

    1. Fenbendazole.org

      Hello Ralph,
      If your dog’s liver values worsen, you may want to consider adjusting the Fenbendazole protocol to reduce potential strain while still maintaining its benefits. In such cases, a lower dose and modified schedule can be helpful. Instead of 444 mg, you can reduce the dose to 222 mg and adjust the dosing schedule to 3 days on, 4 days off. This approach may help lessen the impact on liver function while still maintaining therapeutic effects.
      Additionally, it is essential to always administer Fenbendazole with food to improve absorption and reduce any gastrointestinal irritation. Since your dog is already on CBD oil and supportive liver supplements like Silymarin, you are providing excellent additional liver support. You may also consider TUDCA, as this supplement has been reported to further support liver health.
      It is encouraging that the liver carcinoma is not aggressive and that your dog’s liver function was at 70% when last checked. However, it would be beneficial to continue monitoring liver values through regular veterinary testing to ensure that the protocol remains well-tolerated. If any concerning changes occur, further adjustments may be necessary.
      I appreciate your kind words and am glad you find the website and shared experiences helpful. Wishing you and your dog the best on this journey!

        Hi I’m in the UK looking for a protocol for gliomablastoma for Mt brother please

        1. Fenbendazole.org

          Hello Kerrie,
          Glioblastoma is a complex and aggressive cancer, and while there is no specific Fenbendazole protocol tailored to each cancer type, you can find general dosage guidelines here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/. Since every individual responds differently, your brother can start with the standard Fenbendazole dose and, if he tolerates it well, consider gradually doubling the dose over time. It may also be beneficial to explore Dichloroacetate (DCA) and Sodium Phenylbutyrate (4PBA). DCA helps shift cancer metabolism from glycolysis (Warburg effect) to oxidative phosphorylation, making cancer cells more vulnerable. 4PBA may enhance tumor suppressor gene activity and support metabolic regulation, which could be useful in managing glioblastoma. A combination of these approaches might improve outcomes, but it is essential to monitor his response and adjust accordingly.

    Hi,

    First of all thank you for creating this great website.

    My dog has multiple lipoma’s, fatty lumps. Do you know if Fenbendazole works for treating lipoma’s aswell? Thank you 🙂

    1. Fenbendazole.org

      Hello, Anne.
      Thank you for a question! Fenbendazole targets cancer cells, not normal fat cells. Since lipomas are benign (non-cancerous), they may not respond the same way. Some people claim that fenbendazole shrinks or prevents lipomas, possibly due to its effects on metabolic pathways, but it is harder to suggest its efficiency on lipomas.

  104. Keith

    Hi there, I was diagnosed with stage 3 esophageal cancer in Feb 2024. It has moved into my liver am now stage 4. My question is, is this safe to take and if so, what would be the Protocall

    1. Fenbendazole.org

      Hello, Keith, thank you for a question!
      Fenbendazole is generally considered a safe and low-side-effect substance. However, it is processed in the liver and causes stress to this organ if use for a long time or in high doses. So we suggest not to forget about supplements that should be used to strengthen the liver: milk thistle, curcumin, and alpha-lipoic acid. Also, if you do not use additional blood-thinning medications, an excellent antioxidant is vitamin E. Vitamin D is another important element that should not be forgotten. You can calculate the dose of Fenbendazole with the help of our Dose Calculator:https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Increasing the dose is not prohibited, but we suggest doing this only after examining whether the liver indicators are not significantly elevated and after assessing your general well-being.

  105. amy

    What is the protocol for stage 1 esophageal adenocarcinoma?
    My husband, a Vietnam Veteran was just diagnosed in October at the VA, but he hasn’t started any treatments as of yet but planning on Chemo (carboplatin, paclitaxel) and radiation.
    We are interested in anything we can add to his treatments.

    1. Fenbendazole.org

      Hello Amy,
      For stage 1 esophageal adenocarcinoma, many people combine conventional treatments with metabolic approaches. Since your husband is planning chemotherapy and radiation, you might consider adding Fenbendazole, which many have incorporated into their protocols. You can find the correct dosage based on body weight here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/.
      Other commonly used options include DCA, 2DG, Metformin, Berberine, Methylene Blue, IV Vitamin C, Curcumin, and Mistletoe Injections. DCA and 2DG disrupt glucose metabolism in cancer cells, while Metformin and Berberine support metabolic function. Methylene Blue enhances mitochondrial health, and IV Vitamin C, Curcumin, and Mistletoe help with inflammation, oxidative stress, and immune support.
      Since he is starting chemo and radiation, it is important to monitor his response and adjust as needed. Many of these approaches can be used alongside standard treatments, but a structured metabolic cancer therapy plan may improve outcomes and quality of life. Wishing you both strength on this journey.

  106. Kara

    7yo German Shepherd Koda Bear with newly diagnosed soft tissue sarcoma (that he is currently 3 days post-op emergency “exploratory surgery” in lower abdomen) – we are treating infection first the I want to begin protocol of fenbendazole and ivermectin, along with recommended supplements. He is 82lbs and dosage converts to 888mg/day. I have a 25gram paste that is 10%(?) – the package says 100mg/g. How does this translate to mL’s? Should I purchase a different concentration? Thank you very much for your input. These responses to inquiries are golden.

    1. Fenbendazole.org

      Hello, Kara. Thank you for a great question.
      Koda Bear’s weight: 82 lbs (≈37.2 kg)
      Target dose: 888 mg/day
      Your paste concentration: 100 mg/g (which is the same as 10%)
      Since 1 gram of paste = 100 mg of fenbendazole, we calculate:
      888 mg÷100 mg/g=8.88 grams
      So, Koda Bear would need 8.88 grams (g) of the paste per day.
      How to Convert Grams to mL?
      If the paste is water-based, its density is close to 1 g/mL, meaning 8.88 g ≈ 8.88 mL.
      If it’s oil-based or thicker, it might be slightly more or less than 1:1, but 8.88 mL should be a close estimate.

    Hello, through your answers, I have gathered a lot of useful information. Thank you so much! My husband underwent surgery with a diagnosis of prostate tumor, where two blood vessels were removed and replaced with artificial vessels, and he has been prescribed warfarin for 6 months. After the surgery, he was diagnosed with another condition, T-lymphoblastic lymphoma, and the doctors urged him to undergo chemotherapy because they diagnosed the condition could progress quickly and flare up in the future. If he does not undergo chemotherapy and uses Fenbendazole, what protocol should we follow, and does it interact with the warfarin he has been prescribed? Has Fenbendazole been effective for cases of lymphoblastic lymphoma? Thank you so much.

    1. Fenbendazole.org

      Hello, Lyly.
      There are reports that fenbendazole did not work in a few people with lymphoblastic lymphoma. However, there are also successes when it was combined with chemotherapy and the results were positive. We must note that if you use fenbendazole with chemotherapy, stop taking fenben at least a couple of days before and after the round. We suggest this because fenbendazole inhibits the growth of cancer cells. And chemotherapy most intensely affects rapidly dividing cells, such as hair, nails, skin, intestinal epithelium, and, of course, cancer cells. So if you want the best effect by combining these two methods, we suggest this approach

      1. Dan

        So pause Fenbendazole before and after ANY chemotherapy? Can I add ivermectin to fenbendazole?

        1. Fenbendazole.org

          Fenbendazole is typically paused 2 days before and 2 days after chemotherapy to minimize potential interactions. Ivermectin is sometimes taken alongside Fenbendazole, as they may have complementary effects, but individual tolerance should be monitored.

  109. Margarita

    Hi,

    firstly, thank you very much for your work! I have three questions:

    – is it safe to use for breastfeeding women? If so, then is the above-recommended dosage the same? The 5x a week once a month?
    – if someone is having severe health issues (probably untreated borreliosis) causing muscle pain and overall lack of energy and power, could they use the pills the same as “healthy” adults 5x a week once a month? I heard that using antiparasite treatment can help people with heavy diagnoses at least gain more energy or sometimes completely recover due to better intestine and liver function.
    – could antiparasite treatment affect the function of other drugs people are prescribed by their doctor?

    Thank you!

    1. Fenbendazole.org

      Hello, Margarita!
      Since fenbendazole is poorly absorbed in the human digestive tract, systemic exposure may be low, but there is no data on whether it passes into breast milk or its potential effects on an infant. If considering its use, it’s crucial to consult a healthcare professional for guidance.
      No, fenbendazole does not treat Lyme disease.
      Lyme disease is caused by Borrelia burgdorferi, a bacterial infection that requires antibiotics like doxycycline. Fenbendazole is an antiparasitic that targets worms, not bacteria. It has no known antibacterial properties.
      Yes, antiparasitic treatments like fenbendazole can affect the function of other drugs.
      Liver Enzyme Interaction: Some antiparasitics are metabolized by liver enzymes (e.g., CYP450), which can speed up or slow down the breakdown of other medications.
      Absorption Issues: Some drugs may interfere with or enhance the absorption of others, affecting effectiveness.
      Immune System Effects: If an antiparasitic influences immune function, it could impact drugs like immunosuppressants or antibiotics.

    Hi, wondering if there are any known concerns about someone also taking Clopidoarel and Statins? Looking into this for Ovarian cancer for my 73yo mum (UK), estrogen positive. Diagnosed Jan 22 stage IV (treatment; chemo every 3 weeks for a period, then Avastin, followed by a 6 month break, before going onto weekly chemo over the last few months, took a break over xmas (2024) since suffering a small stroke, then prescribed these meds above) has resumed the last 3 weeks and has decided to stop now due to fatigue and generally feeling unwell with it. Pending Fenben delivery due in the next few days. Good liver/kidney, vitamin D, b12, folate etc. no other concerning blood tests, other than the dredded CA125 being in the tens of 1000s, clean foods/vitamins, removal of toxins has been a key focus. Thank you for any help you can provide.

    1. Fenbendazole.org

      Hello, Gemma, thank you for a question.
      Fenbendazole also involves CYP3A4 metabolism, so there’s a potential but unconfirmed risk of competition for metabolism.
      If fenbendazole inhibited CYP3A4, it could increase statin levels, leading to a higher risk of side effects like muscle pain or liver enzyme elevations.
      No clinically confirmed interactions exist between fenbendazole, clopidogrel, or statins.
      Theoretical concerns exist regarding CYP enzyme competition, but they remain speculative.

    A family member was diagnosed with stage 4 adenocarcinoma about 2 months ago. Has already had 2 rounds of chemotherapy and the chemo hasn’t made any difference. The cancer is in the esophagus, adrenals, lungs, and liver (spreading rapidly in the liver). Is there any situation where fenbendazole would not be recommended? I’m concerned about its effects on the liver.

    1. fenbendazole

      Hello, Mitchell!
      First and foremost, we really sympathize with a family member’s challenging circumstances. Fenbendazole would not be recommended with severe inflammatory bowel disease (IBD) or with pre-existing liver disease. The liver is responsible for metabolizing fenbendazole. If liver function is impaired (e.g., due to cirrhosis, fatty liver disease, or hepatitis), the drug may not be processed efficiently, leading to potential toxicity or accumulation. We would suggest taking liver enzyme tests every few months if you decide to take fenbendazole. Also, your family member should take supplements for liver health, like Milk Thistle (Silymarin), Turmeric (Curcumin), or Alpha-Lipoic Acid (ALA).

      The regiment is really good; the only thing that you might need to consider is that some studies suggest that milk thistle, particularly its active compound silymarin, may have mild phytoestrogenic properties, meaning it could potentially mimic or influence estrogen activity.
      This could be a concern for hormone-sensitive breast cancer (e.g., ER-positive), where estrogen plays a role in tumor growth.
      However, evidence is inconclusive, and some studies indicate that silymarin may actually have anti-estrogenic effects in certain conditions. So silymarin could be repaced with curcumin or alpha-lipoic acid (could be increased to 200-350 mg to replace milk thistle). Also, be sure to take liver enzyme tests (blood test form) every 2-3 months to make sure the liver is in good health.

      1. Scott T.

        This is a great help. Thank you for your feedback.

      A friend of mine is a chiropractor (and my chiropractor). His wife was diagnosed with stage 4 metastatic breast cancer and was in bad shape for a while. He put her on this treatment and she is cancer free now…

      Ivermectin
      – 12mg daily for 3 weeks
      – 6mg daily for 4 weeks
      – 6mg every other day for 6 months

      Fenben
      – 444mg daily for 4 weeks
      – 222mg every other day for 6 months

      And he sent me a PDF of an article called “Targeting the Mitochondrial-Stem Cell Connection in Cancer Treatment: A Hybrid Orthomolecular Protocol”. Google it and read it.

      1. Jacque Tate

        I do have one question: was ivermectin and fenben as noted taken at the same time and not alternated? I haven’t read the Orthomolecular Protocol yet, however.

    3. Jacque Tate

      Scott, I am interested to know why you didn’t add vitamin C to your protocol?

    4. Jacque Tate

      Also, Scott, you may want to consider vitamin K to go along with D3. Something to research so just putting it out there as a recommendation. I learned about that when I was taking high doses of D during covid. God bless your journey.

    hi thank you so much for all that you do and for responding to everyone’s comments, you are truly a lifesaver!
    My friend’s father was diagnosed with a huge tumor on his kidney. She just got the Fenbendazole in a powdered form. The dosage calculator says 444 MG. Can you please explain how to does this using the powder and the best way to give it
    Also, are there any specific brands for curcumin, CBD oil, and milk thistle?
    Thank you!

    1. fenbendazole

      Hello, Cunthia! Thank you so much for your kind words! We truly appreciate your support and are grateful for the opportunity to assist. It means a lot to know that our responses are helpful to you and others.
      Fenbendazole powder is a great choice; all you need to do is weigh the powder on a food scale. Even if the scale does not read to this minimum value, you can round it up to 0.45; 0.4; or even 0.5g. Such a small difference (0.006-0.056g deviation) should not have a major impact on following the protocol. The best way to give it would be with food. Most people sprinkle fenbendazole powder on their sandwiches, yogurt, avocado toast, salads, and so on.
      Now on supplement brands: We do not advertise products and are not an affiliated group, so we do not recommend specific brands, but we can offer the main aspects to consider when choosing a brand. Curcumin: Look for turmeric root extract, preferably organic and sourced from reputable suppliers.
      CBD Oil: Choose CO2-extracted CBD for purity, and ensure it is from organically grown hemp (look for full-spectrum or broad-spectrum options).
      Milk Thistle: Opt for a product containing standardized silymarin content (at least 70-80%) for liver support.
      Read verified customer reviews to assess effectiveness and potential side effects.
      Choose reputable brands with positive feedback and a good track record.
      Avoid products with too many unrealistic claims or lacking transparency.
      Check for clear labeling with dosage, active ingredients, and any additives or preservatives.
      Avoid products with artificial colors, additives, or unknown fillers.
      Prefer supplements with bioavailability enhancers, such as:
      Curcumin + BioPerine (black pepper extract) for better absorption.
      We rally hope this helps you!

  115. LEE

    Hello,
    My father is 59 years old, and he was diagnosed with stage 4 gallbladder cancer last November. He is currently undergoing chemotherapy with gemcitabine, cisplatin, and nab-paclitaxel. I would like to know if it is safe for my father to take fenbendazole.
    If it is safe, I want to start the protocol as soon as possible. He weighs 60kg, so should I follow the protocol of taking 222mg for six days and then taking one day off?
    Additionally, can you recommend any other supplements or supportive treatments to take alongside this?

    1. fenbendazole

      Hello, Lee. Thank you for reaching out to us.
      Yes, your father should follow protocol as it is in our calculator. For a 60-kg man, 222 mg is the appropriate dose. But we also want to stress that taking 2 days before and after chemo would be the best. This is because fenbendazole inhibits cancer cell proliferation, and chemo targets the fastest proliferating cells like nails, hair, skin, and cancer. So to get the best effect from both treatments, we advise him to take a short few day breaks before, during, and after chemo.
      About the supplements, we advise Bio-Available Curcumin 500 mg. Take 1 capsule two times a day after breakfast and lunch, CBD oil 25 mg. Take 1-2 drops (total ~25 mg) under the tongue every day before sleep. Vitamin D3 is preferred over D2. It is proven that additional vitamin D supplementation improves immunity and improves positive outcomes in cancer patients.

    If kidney tumor exists what is protocol with full removal or partial removal

    1. fenbendazole

      Hello Steve,
      If a kidney tumor is removed, either fully or partially, the focus post-surgery is on recovery and protecting the remaining kidney tissue. Hydration is critical, along with avoiding medications or supplements that could strain kidney function. After 2-4 weeks of healing, depending on the recovery process, you can typically begin a protocol such as fenbendazole. A common approach is 222 mg daily, 6 days on and 1 day off, adjusted based on body weight. For partial removal, the goal is to preserve as much kidney function as possible.
      In addition to fenbendazole, supportive supplements like curcumin, omega-3 fatty acids, and vitamin D3 can help manage inflammation and support overall health. Maintaining a kidney-friendly diet with moderate protein intake and regular hydration can also play a significant role in recovery. Regular monitoring of kidney function and overall health is essential to ensure the safety and effectiveness of any protocol you choose. Combining these measures with careful observation can help optimize recovery and long-term outcomes.

  117. Sarah

    My grandson, 3 yrs old, 42 lbs has adrenocortical carcinoma, with a tumor on his kidney now and a couple of small spots in his lung. He’s reached the end of typical cancer treatment. His parents started using fenbendazole but the dosage is hard to figure. 222 mg or some reduction of that based on his weight?

    1. fenbendazole

      Hello, Sarah!
      Thank you for a comment. We would not recommend using fenbendazole for such a young child, as we do not yet have enough data on how it affects young children. We also indicate in our dosage calculator that we do not recommend using this remedy for children under 2 years of age. However, if you decide to use it, we suggest starting with a reduced dose, at least 100mg. We advise you to carefully monitor your child’s well-being and, if you have even the slightest questions, consult a trusted pediatrician

    2. Ken

      Hi Sarah,

      If this was happening to my child, I would get in contact with William Makis MD in Canada. I would send him a message on X, Instagram, or Facebook. You can also follow him on Substack. Best of luck with everything.

    Should the CBD oil have THC? If so, what should ratio be?

    1. fenbendazole

      Hello Mik,
      Yes, CBD oil with THC may be beneficial, especially for cancer treatment or pain management, as the two compounds can work synergistically to enhance therapeutic effects (known as the entourage effect). A common starting point is a 1:1 ratio of CBD to THC, as this provides balanced effects and has been studied for various medical conditions, including cancer and chronic pain.
      For those who prefer less psychoactivity, a ratio like 10:1 (CBD:THC) or higher might be better, as it provides therapeutic benefits with minimal THC effects. Always choose a high-quality product with third-party lab testing to ensure purity and accurate ratios. Adjust the ratio and dose based on your specific needs and tolerance.

  119. Johan

    Hello,

    According to the guidelines for the “Preventing cancer for someone who was always cancer-free – prophylactic protocol,” it recommends:

    “Fenbendazole 222 mg. Take 1 capsule three times a week…”

    I weigh 100 kg, and I’m wondering if I should adjust the dosage to 444 mg based on body weight, or if the standard 222 mg is sufficient for preventive purposes. I’m a bit unclear on this and would appreciate any clarification. Thanks!

    Johan.

    1. fenbendazole

      Hello Johan,
      Thank you for your question. It seems there might be some confusion with the dosage calculator. For someone weighing 100 kg, the recommended dose for fenbendazole would indeed be 444 mg, as the prophylactic protocol adjusts based on body weight. The guideline of 222 mg applies to individuals weighing between 20.1 kg and 89.9 kg. Since your weight exceeds 90 kg, the calculator would indicate 444 mg as the appropriate dose.
      For preventive purposes, the protocol remains the same in terms of schedule: take the appropriate dose three times a week. You can double-check your weight and dosage using the calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/.

  120. Ina

    Hi there. First of all, thank you for your site and also especially for feedback given. I was diagnosed in May 2023 with DCIS, breast cancer stage zero but with aggressive type cells. I had surgery in July 2023. I also started Joe Tippins’ protocol a few weeks prior to surgery in 2023. I take: fenbendazole (panacur C or safeguard), 1 gram packets 3x/week; berberine 500 mg, 2x/day; onco adjunct P2 with 1062 mg curcumin + 708 mg quercetin daily; quercetin 800 mg with bromelain 165 mg daily; CBD oil 25 mg sublingually daily; vit D3, 4000 IUs daily; vit c 1000 mg daily; zinc 50 mg daily. I check my liver every six months, and that seems to be fine. However, in April of 2024 my BUN and Calc BUN/creatinine numbers were high and remain high. I also have changed my diet to a low carb, low sugar (try to avoid regular sugar but try to use organic stevia or monk fruit no erythritol) diet. Do you know if any of this could affect my kidneys? And could you advise on kidney support? Thank you!

    1. fenbendazole

      Dear Ina,
      Elevated BUN and BUN/creatinine ratios can sometimes result from factors like dehydration, high protein intake, or increased stress on the kidneys. Your low-carb diet might include a higher protein intake, which can elevate BUN levels due to the byproducts of protein metabolism. Dehydration can also contribute to these results, so ensuring adequate hydration by drinking at least 2-3 liters of water daily is essential to support kidney function. Some of the supplements you are taking, such as berberine, curcumin, or quercetin, are generally safe but could contribute to kidney stress in high doses or when combined with multiple compounds. Fenbendazole is also considered safe, but regular monitoring is a wise approach.
      To support your kidneys, you might consider adding herbal supports like dandelion root, nettles, or cranberry extract, which are known for promoting kidney health. Balancing electrolytes like magnesium and potassium can also help maintain proper kidney function, especially if you are on a low-carb diet. Reducing sodium intake, if applicable, could be beneficial for overall kidney health, particularly if blood pressure is a concern. Continuing your six-month monitoring of liver and kidney function is an excellent step, as it allows you to track changes and make adjustments to your protocol as needed.
      Your current regimen includes many beneficial elements for overall health and cancer prevention. By focusing on hydration, maintaining an appropriate protein balance, and adding some kidney support, you can work to bring your BUN levels into a healthier range. Wishing you continued strength and success in managing your health.

    Any protocol for Blood Cancers such as CLL?

    1. fenbendazole

      Dear Joel,
      There is not a specific protocol tailored to each type of cancer, including blood cancers such as CLL. The approach generally depends on the aggressiveness of the cancer, which determines the dosage and schedule of administration. I recommend using this dosage calculator: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/. At the bottom of the page, you will find detailed information on usage schedules, as well as other important tips to follow. This resource provides clear guidance for developing a protocol that may be suitable for your situation.

  122. Talou Sophro-Zen

    Hello,

    I am writing to you from France about a friend who has been diagnosed with a stage 3 glioblastoma. He is scheduled to undergo several radiotherapy sessions over three weeks while taking oral chemotherapy with Temodal.

    Weighing 74 kg, and based on the dosage calculator, he would need to take 222 mg of fenbendazole. However, from my research, it appears that mebendazole crosses the blood-brain barrier more effectively than fenbendazole. What is your opinion on this? Would it be more appropriate to consider mebendazole in his case?

    Additionally, do you think combining his treatment with DCA (dichloroacetate) could be beneficial, considering the low survival rate associated with such an aggressive cancer?

    Thank you so much for any advice and recommendations you could provide.
    Kind regards,

    1. fenbendazole

      Hello,
      Thank you for reaching out, and I am sorry to hear about your friend’s diagnosis. Glioblastoma is an aggressive cancer, and exploring additional options alongside conventional treatments can be valuable. Regarding fenbendazole versus mebendazole, you are correct that mebendazole crosses the blood-brain barrier more effectively, making it potentially more appropriate for glioblastoma. Studies suggest that mebendazole can disrupt cancer cell growth by targeting microtubules, and it may enhance the effects of standard treatments like temozolomide and radiotherapy. Fenbendazole is also used by some due to evidence and its low toxicity profile, but mebendazole could be more suitable in this case due to its ability to penetrate the central nervous system.
      Considering DCA (dichloroacetate) as part of the treatment plan could also be beneficial. DCA targets the metabolic vulnerability of cancer cells by shifting their energy production from glycolysis to oxidative phosphorylation, potentially making them more susceptible to chemotherapy and radiotherapy. Combining DCA with standard treatments, as well as an integrative approach that includes supportive supplements like thiamine (to prevent DCA-induced neuropathy) or curcumin to manage inflammation, could help improve outcomes. It is important to closely monitor his response and adjust as needed to optimize the strategy. Wishing you and your friend strength and hope in navigating this challenging journey.

  123. Syl

    I ordered Safeguard and it’s a liquid form. How much is the dosage for 222mg?? I’m using it to cure Chondrosacoma.

    1. fenbendazole

      Hello Syl,
      To calculate the dosage of liquid Safeguard for 222 mg of fenbendazole, check the concentration on the product label. If it contains 100 mg of fenbendazole per 1 mL, you would need 2.22 mL to get the required 222 mg. Use a syringe for precise measurement and ensure consistency in administration according to your treatment protocol.

    Hello, my father was diagnosed with bile tract cancer, there would be an adenocarcinoma in this place but no visible tumor either on the pet-scan or an IRI, no metastases either. Do you think fenbendazole could save him from a terrible operation that is proposed to him? He is offered the removal of the duodenum and the head of the pancreas as well as the bile duct… Another question, I only have access to panacur 500mg in tablets, do you know what dose of fenbendazole is really in these tablets? Can you advise me the best protocol for him? Would 3 days of fenbendazole and 4 days of rest be enough? I’m really afraid of destroying his liver… Thank you for everything, you are exceptional, thank you in advance!

    1. fenbendazole

      Hello Jo,
      Thank you for reaching out, and I am sorry to hear about your father’s diagnosis. Fenbendazole may be useful in treating various types of cancer, including bile tract adenocarcinoma. However, the effectiveness of the treatment depends on how the body and the tumor respond to it.
      The amount of fenbendazole in the medication should be carefully checked on the packaging to ensure accurate dosing. The dosage of fenbendazole typically depends on body weight, with the most common doses being 222mg or 444mg per day. To determine the appropriate dosage for your father, you can use the calculator provided here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/. A dosing schedule of 6 days on and 1 day off is usually suggested, as it is less likely to strain the liver compared to more aggressive protocols.
      Liver enzymes (ALT, AST) should be monitored regularly through blood tests, and liver-supporting supplements like milk thistle or N-acetylcysteine (NAC) can be considered.
      While fenbendazole may offer some potential benefits, it is unlikely to substitute for surgery if his medical team considers the operation necessary. I hope this helps, and I wish your father the best possible outcome.

      1. Sinbad88

        Hi Fen,

        !st of all, I want to tell you, that you and this site are a God send. My question is my wife has had breast and colorectal cancer, but thank God she’s doing fine now. We drink kefir, eat yogurt, and take numerous supplements. A few of the supplements are nattokinase (12,000 f.u./day), curcumin (BCM-95, 650 mg./ day, yielding 1,000, mg. total) , and ivermectin as a prophylactic. My wife takes 12 mg. ivermectin 2X/week. She weighs 105 lbs.. My question is I’ve read where people have taken 1 gram of fenben 3 days a week, with 4 days off. I ordered some fenben pills that are 500 mg each. I was going to have her take 2 of the 500 mg. pills 3 days a week, but from what I’ve read here that sounds like it is too much. What is your opinion on this. Not asking for medical advice, just your opinion. Thank you so much for your time.

        1. fenbendazole

          Hello,
          Thank you so much for your kind words, and I am glad to hear your wife is doing well. It is great that you have both adopted such a proactive approach to health with kefir, supplements, and a thoughtful protocol. Regarding fenbendazole, it is important to consider the recommended dosage guidelines based on weight. At 105 lbs (around 48 kg), the typical dose for fenbendazole is 222 mg per day on a schedule of 3 days on and 4 days off for a prophylactic or maintenance protocol.
          Taking 1 gram (two 500 mg pills) three times a week would exceed the recommended dose for her weight and could potentially strain the liver over time. Fenbendazole is generally well-tolerated, but higher doses are not always more effective and may increase the risk of side effects. It is best to stick to the weight-based dose for safety and long-term use.
          Your current protocol, with ivermectin as a prophylactic and supportive supplements like nattokinase and curcumin, sounds well-rounded. If you adjust the fenbendazole dosage to match her weight, it should complement what you are already doing without unnecessary risk. Wishing you and your wife continued health and strength!

  126. Jeff

    Hi there, thanks for all the questions you answer, its an important subject.
    Seven months ago I was diagnosed with a 2cm in size Pancreatic Neuroendocrine Tumor (PNET). Pathology indicated Grade 1, with very very slow growing cells. No other cancer anywhere in body. I began 222MG Fenben once a day, over 7 months ago and following the Tippen protocol. MRI at 3 months showed no change in size. After 3 months and no change in tumor size, I increased to 222MG Fenben 2x per day. I take Milk Thistle as well, and have no kidney or liver issues. At 7 months (4 months after increasing dosage), another MRI showed no change in size, no growth. Question is, after 7 months on Fenben in total, and no change in tumor size, is it time to give up on Fenben, or continue? I’ve heard Fenben can take anywhere from 2-18 months to show results. Then again, the PNET I have is not an aggressive type “cancer” so not sure if Fenben will ever have an impact. The good news is no growth. Appreciate your thoughts. Thanks much for your response.

    1. fenbendazole

      Hello Jeff,
      Thank you for sharing your experience. It is excellent news that your tumor has remained stable over the past seven months, and your dedication to the protocol is commendable. As Pancreatic Neuroendocrine Tumors (PNETs) are slow-growing, it can take longer to observe significant changes from treatments like fenbendazole. Given the tumor’s stability, continuing Fenben may still be worthwhile.
      To enhance your protocol, consider incorporating Dichloroacetate (DCA) and Phenylbutyrate (4PBA). DCA targets cancer cells by restoring normal mitochondrial function, promoting apoptosis (programmed cell death), and complementing Fenben’s action. Phenylbutyrate is known to reactivate tumor suppressor genes and correct molecular defects in cancer cells, making it a promising addition. Suggested dosages are 20-25 mg/kg/day for DCA, divided into two doses, and 10-15 grams of Phenylbutyrate daily, split into 2-3 doses.
      Berberine has effects in lowering glucose and insulin levels, which can help starve cancer cells and reduce their growth. The typical dose for berberine is 500 mg, taken 2-3 times per day with meals.
      It is essential to regularly monitor liver enzymes and overall health while following this protocol to ensure safety and efficacy. Additionally, maintaining tumor stability is a positive outcome, and this protocol can serve as a preventive measure to discourage growth and keep the condition under control. Regular imaging and bloodwork are crucial to track progress.
      Your proactive approach is already yielding positive results, and with consistent monitoring and adherence to this refined protocol, you can continue to focus on prevention and well-being.

    Hi there, I was just wondering if it was normal to feel like a tumor is growing (feeling more swollen) while on Fenben protocol? I have been on for 2 months and some days feel normal but some days feel like tumor is more swollen? I thought I read somewhere that people did feel like there tumor was getting bigger but not to stop with protocol? Would love to hear people with any experience with this. Thanks in advance!

    1. fenbendazole

      Hi, Willy. Thank you for a great question!
      Possible Explanations for Swelling Feeling:

      Tumor Lysis Syndrome (TLS) or Inflammation Response:
      When cancer cells die off quickly (a process called apoptosis), the immune system may react, causing localized inflammation or swelling. This is sometimes referred to as a “healing crisis” and can make the tumor feel larger or more swollen temporarily.
      If Fenbendazole is causing tumor cell death, immune cells (like macrophages) may be moving into the area to clean up dead cells, leading to swelling.

      Tumor Flare Effect:
      Some cancer treatments cause the tumor to appear larger or feel swollen temporarily as part of a “flare” response. This occurs due to the accumulation of immune cells or fluid in the area of the tumor. While more common with hormonal therapies, the body’s natural immune response may cause something similar.

      Fluid Retention (Edema) Around the Tumor:
      Sometimes, tumors can produce chemicals or cytokines that lead to fluid retention around them. This can make the tumor feel larger even though the tumor itself may not be growing.

      Normal Fluctuations in Tumor Size:
      Some tumors naturally expand and contract slightly due to changes in blood flow, especially in tumors that are actively growing or shrinking. This might be misinterpreted as “swelling.”

      If the swelling is consistent, persistent, or associated with new or worsening symptoms, it’s important to consider the possibility of tumor growth. If you’re on Fenbendazole and not taking other treatments, it’s essential to discuss this with a healthcare provider to rule out tumor progression.

        Thank you for the reply! Appreciate it!

  128. Deanna

    First of all Thank you fenben.org you are making a huge difference in people’s lives. I am amazed by the personal responses you provide.

    Asking for a family member, 40 year old female with 2 little babies, 2 and 4 years old. She is fighting for her life with those babies.

    Her original cancer was late stage nasopharyngeal, successfully treated with chemo and radiation. 6 months later stage for small cell lung cancer, now spreading to vertebra and elsewhere in her body.
    Chemo, radiation and immunotherapy have failed. She wants to start on your protocol but 444mg a day and adding berberine and quercetin.
    She is on blood thinners and is wondering if this protocol is safe while on blood thinners?
    Also what are the symptoms of liver damage and how to know when to take a break?
    Thank you

    1. fenbendazole

      Dear Deanna,
      Thank you for reaching out and for your kind words about fenbendazole.org. We are truly touched by your appreciation and are deeply sorry to hear about your family member’s challenging situation. Her determination to fight for her life and be there for her little ones is incredibly inspiring.
      Fenbendazole itself does not have reported interactions with blood thinners, so it is generally considered safe. However, both berberine and quercetin may affect blood clotting. Berberine, in particular, has properties that may slightly thin the blood by reducing platelet aggregation, which could theoretically increase the risk of bleeding. Quercetin also has mild effects on platelet function. To ensure safety, it would be wise to monitor for any signs of unusual bruising, bleeding, or prolonged wound healing during the protocol.
      Signs of liver stress or damage can include:
      – Persistent fatigue or weakness
      – Loss of appetite or unexplained weight loss
      – Yellowing of the skin or eyes (jaundice)
      – Dark-colored urine or pale stools
      – Nausea, vomiting, or discomfort in the upper right abdomen
      – Generalized itching or swelling in the legs and abdomen
      To stay proactive, it is helpful to watch for these symptoms closely. If any appear, it is important to take a break from the protocol to allow the liver to recover. Liver function can also be supported by incorporating supplements like milk thistle, NAC (N-acetylcysteine), or foods that promote liver health, such as cruciferous vegetables and antioxidant-rich fruits.
      Starting with 444mg of Fenbendazole daily, along with berberine and quercetin, is a reasonable approach that many individuals in similar circumstances have found helpful. Careful attention to how the body responds and a willingness to adjust the protocol as needed are key. It is also advisable to include other supportive measures, such as a healthy diet, hydration, and rest, to help her body manage the additional load.
      Her strength and willpower, combined with a thoughtful approach to her care, can make a significant difference. We are here to support you and her every step of the way. If you have further questions, please do not hesitate to reach out.

    Protocol
    Take fenbendazole once daily for 3 days in a row (Monday-Wednesday). Take no fenbendazole on the remaining weekdays (Thursday-Sunday). Repeat this every week.

    How long for ? years ? months ? i dont have cancer but not far away from cancer, I have sjogrens disease soon to have final complication of non-hodgkin lymphoma just waiting waiting waiting on NHS Uk waiting lists

    1. fenbendazole

      Hello Franko,
      Thank you for your question. If you do not currently have cancer but are concerned about its potential development due to underlying conditions such as Sjögren’s disease, using fenbendazole as a preventive measure is not a standard or widely studied protocol. However, some individuals choose to use fenbendazole long-term for preventive purposes based on personal reports and experiences.
      If you decide to proceed with the protocol you mentioned (3 days on, 4 days off), it is important to approach this cautiously. Regularly monitor your overall well-being and consider supporting your liver health with supplements such as milk thistle. There is no definitive duration for using fenbendazole preventively, but many people reassess their usage every few months to ensure there are no adverse effects.
      Some patients choose to take fenbendazole long-term, even for life, especially after achieving No Evidence of Disease (NED). They often use it as a preventive measure to reduce the risk of recurrence.

    Hi there, my dog was diagnosed with stage 4 pituitary cancer a few months ago. Although the vet said he’s at the final stage and could be gone any day now, we decided to try targeted therapy and surprisingly saw great improvements. A few months have passed and he is still on the pill, but symptoms have plateaued and he no longer seems to be getting better.

    I want to start him on the Panacur protocol. SInce it can be used with chemo, I’m assuming it can be used in conjunction with targeted therapy as well. He’s currently taking the pill Monday, Wednesday and Fridays, so fenbendazole will overlap with the targeted medication for at least a day. Would that be ok? When will be the ideal days to dose? thanks in advance!

    1. fenbendazole

      Dear Lea,
      Thank you for sharing your dog’s journey. It is wonderful to hear that he has shown significant improvement despite the challenges of a stage 4 pituitary cancer diagnosis. Fenbendazole is generally considered a safe and well-tolerated drug and is often used in conjunction with other therapies, including chemotherapy and targeted treatments. While it is promising that these therapies can work together, it is always important to proceed with care and monitor your dog’s well-being closely.
      Since your dog is already on medication three days a week (Monday, Wednesday, and Friday), adding fenbendazole on overlapping days should generally be safe. However, it would be ideal to start with a lower dose of fenbendazole and observe for any signs of discomfort, changes in behavior, or side effects. A common protocol for dogs includes administering fenbendazole daily for three days, followed by a four-day break, but you may need to adjust based on your dog’s specific needs and other medications.
      Additionally, ensure that your dog remains well-hydrated and monitor for any changes in appetite, energy levels, or stool consistency. If any concerns arise, consult your veterinarian promptly to ensure the treatment is being well-tolerated. With careful observation and adjustments, fenbendazole may complement the current therapy and provide additional benefits.

        What is the recommended dose of fenben for dogs taken as a drug to prevent cancer, not treat parasites?

        1. Fenbendazole.org

          Hello, Jacque!
          There is currently too little data to confirm a PREVENTIVE dose, but there is data on how much is needed to manage and treat active cancer. You can find it in our fenbendazole dosage guide and calculator.

    Hello i am from Holland, so i am sorry iff my English is not quitte well🙈
    My husband is recently diagnosted with pancreas cancer and has metastasen in his liver and doctor has told us that without chemo he has about 3 months to live. He has startet last week with fenbendazol once a day after a meal. He also takes curcumin once a day. This treatment is new for us. How can we figure out if it works? In Holland are some doctors very difficult about alternitive medication so when we cut be asking for a CT-scan they probebly wanne no why…🙈.

    1. fenbendazole

      Hello Corina,
      Fenbendazole is often considered a long-term therapy, with potential effects becoming noticeable after 2 to 4 months of consistent use. It is crucial to maintain patience and closely monitor your husband’s condition during this period.
      Regular monitoring of liver enzymes is essential, as fenbendazole can impact liver function. Incorporating milk thistle into his regimen may support liver health. Ensuring adequate hydration is also important, so encourage him to drink plenty of water. Additionally, CBD oil has been reported by some patients to provide supportive benefits.
      Regarding imaging to assess the effectiveness of the treatment, I understand your concern about requesting a CT scan, especially when discussing alternative therapies with healthcare providers. In the Netherlands, access to diagnostic imaging like CT scans typically requires a referral from a general practitioner (GP) or specialist. However, some private clinics may offer imaging services without a referral, though this is not common practice.
      For instance, DC Klinieken offers radiological assessments, but they require a referral to make an appointment. Similarly, Open MRI Zen accepts patients with a referral letter for MRI scans or ultrasounds.
      Given these requirements, it would be advisable to discuss your husband’s desire for a CT scan with his GP or oncologist. You can express your interest in monitoring the progression of his condition through imaging, which is a standard practice in cancer care. By focusing on the importance of tracking the disease’s progression, you may be able to obtain the necessary referral for a CT scan.

  132. Laura C.

    Hi, I’m wondering if fenbendazole could have any beneficial effect on small bowel obstruction due to cancerous tumor and stage 4 metastasized abdominal cancer? My dad is told he may not be absorbing much for nutrients…hasn’t had a bowel movement in 2-3 weeks but still urinates. He had a NG tube through his nose going down into his stomach to drain fluid build up. He is currently taking dexamethasone, hyoscine butylbromide, haloperidol (as needed), hydromorphone (as needed) and has started octreotide. He has also suffered a stroke 6 months ago, and has had prostate cancer/surgery and pancreatic cancer in the past and had 1/2 pancreas removed and has no spleen… any help would be greatly appreciated. Thank you.

    1. fenbendazole

      Dear Laura,
      Thank you for sharing your father’s situation. I understand how challenging this must be, and I hope to provide some helpful insight. Some individuals with advanced cancer have reported positive outcomes when incorporating it into their protocols. Fenbendazole may interfere with cancer cell metabolism and growth, potentially offering benefits even in advanced stages. Given your father’s condition, including the bowel obstruction and his complex medical history, start with a low dose (typically 222mg daily, based on weight) and monitor his overall well-being closely. Consult with a healthcare provider before making any changes to his regimen.
      Since nutrient absorption is compromised, it is important to support his liver. Adding milk thistle can help protect liver function, and monitoring liver enzymes (ALT, AST, bilirubin) regularly is recommended to ensure safety. For his bowel obstruction, maintaining hydration is crucial as dehydration can worsen the issue. Gentle options like rectal enemas, digestive enzymes, or small amounts of natural oils (e.g., olive or coconut) may ease stool passage if there’s partial obstruction, but only with medical supervision. Avoid any measures that could strain his system further, and watch for emergency signs like severe pain or vomiting, which require immediate attention.
      Even with these challenges, many have found fenbendazole helpful alongside proper care. Small improvements can bring hope, and staying proactive with his care may make a significant difference.

  133. Laura Matula

    My brother has stage 4 larynx cancer and is not responding to treatment. I want to start the treatment protocol but have only one question/concern. He eats they a peg tube and liquid “formula” only. It says a lot about taking with meals, but he doesn’t have meals. He is on a “drip feed” and essentially eats 24 hours a day. What do I need to do differently, if anything? I was just going to put it in his formula.
    Thank you so much for everything you do for everyone in need!! Good bless you!
    Laura

    1. fenbendazole

      Hello, Laura.
      The main aspect is that fenbendazole is best absorbed with fat (it is a hydrophobic substance that breaks down only in fat and not in water). It is also recommended that you take it with or after food so that fenbendazole stays longer in the digestive system and is absorbed more.

  134. Greg V

    I’ll be starting my cat, Derrick in Fenbendazole to hopefully help with nasal cancer. Is there any benefit of splitting the dosage in half and giving twice a day rather than once? He weighs 17 lbs which calls for 444 mg, which is the same for a 200 lb human. Why is there such a dosage difference between humans and animals?

    1. fenbendazole

      Dear Greg,
      Thank you for your question, and I hope Derrick responds well to the treatment. When administering fenbendazole to animals, splitting the daily dose into two smaller doses given at different times can be beneficial. Cats and other animals generally have faster metabolisms than humans, meaning their bodies process and eliminate drugs more quickly. By dividing the dose, you allow for a more consistent concentration of the drug in the bloodstream throughout the day, increasing its efficacy and prolonging its ability to combat cancer cells.
      In terms of dosage differences between humans and animals, it is important to understand that dosages are not solely based on weight but also on differences in metabolism, absorption, and the way each species processes medications. For example, humans have a slower metabolic rate compared to most animals, so a single dose can remain active in the system longer in humans. Animals, particularly cats, metabolize substances much faster, which is why their dosage per weight appears proportionally higher.
      For Derrick, splitting the 444mg dose into two smaller doses (e.g., 222mg twice daily) may optimize the treatment by maintaining a more stable drug level in his system. It is always a good idea to monitor his response to the treatment closely and consult with a veterinarian for personalized guidance. Wishing you and Derrick the best in his journey toward recovery!

  135. Elfi

    My 8 year old dog had a spleenectomy 2 weeks ago (cancerous). He is fully recovered now and doing well. My treatment so far has been medicinal mushrooms; want to start now on the Fenben-treatment as a preventative of relapse. I am concerned about possible liver metastasis (tumor has been bleeding) and treat that with urea. – Do all these go well together or is it better to go on the urea (plus milkthistle) on the Fenben-free periods? Any suggestions on how many cycles of treatment?
    Thank you – I appreciate your work!!

    1. fenbendazole

      Hello Elfi,
      Fenbendazole has been used by many pet owners as part of a preventative protocol against cancer relapse, and it is generally well-tolerated in dogs. Based on the weight of your dog, you can determine the appropriate dosage using the Fenbendazole Dosage Guide provided here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Regarding your question about combining Fenbendazole with urea, medicinal mushrooms, and milk thistle, it is important to proceed cautiously, as the liver plays a significant role in metabolizing these treatments. Using urea and milk thistle during Fenbendazole-free days could help reduce the liver’s workload and minimize potential interactions. However, given the complexity of combining these treatments, consulting with your veterinarian is highly recommended. A veterinarian can provide tailored advice based on your dog’s specific health condition, weight, and treatment history.
      Monitoring your dog’s overall well-being, including appetite, energy levels, and any changes in behavior, is critical during this process. We hope this helps and wish you and your dog continued health and recovery!

  136. John

    My mom was diagnosed with pancreatic cancer March 2024. She was doing chemotherapy for 6 months and her last session was 2 weeks ago

    She has been intrigued with fenbendozole but she has now been prescribed Lynparza

    Is it ok to take fenbendozole and Lynprza?

    How many mg of Vitamin E should she take?

    1. fenbendazole

      Hello John,
      It is generally possible to use fenbendazole alongside Lynparza (olaparib), but it is important to monitor your mother’s overall well-being, particularly her liver enzymes, as both treatments can impact liver function. Close supervision and regular checkups with her healthcare provider are recommended to ensure the combination remains safe and effective for her condition.
      Vitamin E is often suggested as a supportive supplement when using fenbendazole due to its antioxidant properties. However, it is crucial to be cautious with the dosage, as Vitamin E has blood-thinning effects, which may increase the risk of bleeding—especially significant for patients who may have blood clotting concerns or are undergoing treatments like chemotherapy. Because of this, the ideal dosage varies, but a typical dose is between 200-400 IU daily. It is best to confirm the appropriate amount with her doctor, who can take her specific health needs into account and assess any additional risks.
      Taking all of these factors into consideration can help ensure she gets the maximum benefit from her treatment while staying safe.

      1. Missy

        Can you tell me how to measure out a human dose of safe-guard equine dewormer?

        1. fenbendazole

          Dear Missy,
          To measure a human dose using Safe-Guard Equine Dewormer, which typically contains 10% fenbendazole (or 100 mg per gram), you would need to calculate based on the required dose.
          For example:
          – A 222 mg dose would require approximately 2.2 grams of the paste.
          – A 444 mg dose would require approximately 4.4 grams of the paste.
          It is essential to check the concentration on the Safe-Guard packaging to confirm that it contains 10% fenbendazole, as this calculation is based on that standard.

      2. vicki

        Hello,

        Can Fenbendazole be used in a case where the liver is almost eaten by metastases? If yes, how many mg/ dose/day? And can I combine it with Ivermectin?

        1. fenbendazole

          Hello Vicki,
          Thank you for your question. We are an informational page focusing on fenbendazole, and unfortunately, we do not have specific information about ivermectin or its potential combination with fenbendazole.
          Fenbendazole has been reported to be used in cases of advanced cancer, including those with significant liver involvement. However, it is essential to approach such situations cautiously, as the liver’s compromised state may affect how the body processes and tolerates the compound. For dosing, a commonly used starting point is 222mg per day, taken with food, for 4–6 days a week. Starting with a lower frequency, such as 4 days per week, and gradually increasing if well-tolerated, may be advisable in severe cases.
          Since the liver is a primary organ for metabolizing substances, close monitoring of liver function, general well-being, and blood parameters is critical. Taking fenbendazole with food can improve absorption and reduce any potential gastrointestinal discomfort.
          We encourage careful consideration and monitoring if you decide to proceed and wish you strength and positive outcomes on this journey.

      3. Shelby

        Is it valid to use Fenbendazole to prevent cancer? In addition to preventing cancer, what else does it help the body with? How does the medicine work to prevent cancer?

        1. fenbendazole

          Hello Shelby,
          Fenbendazole is commonly known as an antiparasitic medication, but it has gained attention for its potential use in cancer prevention and treatment based on reports and emerging studies.
          To determine the correct dosage for cancer prevention, you can use the dosage calculator provided on our platform. In the “Protocol” section of the calculator, select the option labeled “Cancer prevention protocol” to find the appropriate dosage tailored to your needs.
          In addition to its potential role in cancer prevention, Fenbendazole may help the body in other ways due to its antiparasitic properties. It works by disrupting the microtubule structures in parasitic organisms, effectively eradicating them. This action may support overall health by addressing hidden parasitic infections that could otherwise weaken the immune system.
          Fenbendazole’s anticancer mechanisms are increasingly recognized and supported by research. It acts by disrupting the microtubules within cancer cells, which are critical for their structure and division, thereby effectively inhibiting their proliferation. Additionally, Fenbendazole has been shown to stimulate the immune system, enhancing its ability to detect and eliminate abnormal cells. It also interferes with the metabolism of glucose in cancer cells, depriving them of the energy needed for growth and survival. These mechanisms collectively contribute to its promising role in cancer prevention and treatment.

  137. William

    Hi, I have splenic marginal b lymphoma and 7 years ago was diagnosed with Gleason 6 prostate problem. With supplements I have no urinary problems.

    My lymphoma responded extremely well to Rituximab and seems to have gone back to normal size. I will have another petscan in November to see for sure.

    I have started the protocol (the fenbendazole is Panacur C) but am struggling with the cbd. I got the 25 mg Capsules recommended by a couple of oncologists who recommend the Tippens protocol. However, CBD just didn’t work for me. My body tenses up and I am extremely hungover the next day. I don’t drink in no small part because I hate hangovers so really don’t like taking the 25 mg of cbd.

    I have thought about switching to drops and starting with a very small amount.

    How important is the CBD to the protocol?

    If I can only take a tiny amount is it worth taking?

    1. fenbendazole

      Dear William,
      Thank you for sharing your experience, and it is great to hear that your lymphoma responded so well to Rituximab. Regarding CBD, it is not considered a crucial component of the protocol, especially if it causes you discomfort. Many find that fenbendazole alone provides significant benefits without the need for CBD.
      If you are interested in trying a smaller dose, switching to CBD drops and taking a very minimal amount could help you gauge its effects without the intense side effects. However, if even small amounts continue to be uncomfortable, it may be best to focus on the other components of the protocol.

      1. kali

        I do not have access to CBD oil in India. What are my supplementary options with fenbendazole.

        dosing with 20ml/444mg(panacur c 2.5%) daily and 60mg ivermectin daily. +vitamin d3 60000IU + vitamin C+zinc (500mg+22mg)

        already on montelukast sodium, levocetrizine, anti-coagulant clopidogrel 75mg, statin rosuvastatin 10mg, anti-convulsant leviteracetam 750mg x 2 daily, 5mg prednisolone, etofylline/theofylline for COPD.

        diagnosed with final stage lung cancer metastasized to brain. KRAS mutation, targeted gene and immuno therapy not possible. chemotherapy not an option since he is completely bed ridden

        what are the other supplements that i should consider taking – i am thinking I should add TUDCA (milk thistle not a posisbility owing to anti-coagulant) and curucmin. Kindly let me know, want to make sure liver is healthy enough to fight the cancer for the next 2-3 months

        1. fenbendazole

          Dear Kali,
          Given the situation and current medications, adding TUDCA (tauroursodeoxycholic acid) and curcumin as supplements could indeed be beneficial, particularly to support liver health and overall resilience. TUDCA can be a suitable alternative for liver support, especially since milk thistle is not an option due to its potential interactions with anticoagulants. TUDCA may help promote liver function without interfering with blood-thinning medications. Adding curcumin could also be advantageous due to its anti-inflammatory and antioxidant effects, which may help manage inflammation and potentially support immune response. To ensure maximum absorption, curcumin is best taken with a fat source and black pepper (piperine).
          Beyond these, you may consider a few additional supplements, always under guidance from a healthcare provider given the complex medical profile. Melatonin, often used for sleep support, has been explored for its antioxidant properties and potential effects on cancer pathways. A common approach is around 10-20 mg taken at night. Omega-3 fatty acids may support overall health, including heart and immune function, which could benefit patients with advanced cancer. Additionally, a high-quality probiotic could help maintain gut health, which is often impacted by medications, and may provide immune support. Lastly, B-complex vitamins may help counteract fatigue and nutrient depletion from medications by supporting energy and cellular function.
          Monitoring for any side effects or interactions with existing medications is essential, especially given the complexity of the current treatment regimen.

      2. William

        I started the protocol last Fall (plus ivermectin and minus CBD). 5 weeks later I had a petscan and my oncologist was shocked that all taxes of my marginal b lymphoma were gone. My blood work is now normal too.

        Have there been any studies indicating when it is safe to switch to the less frequent remission protocol of 3 days a week?

        1. Fenbendazole.org

          Hello, William!
          First of all, congratulations! And second of all, we do not have any robust data on a time frame in which you may switch. There are some personal stories about going to mild protocol at 6 months since NED, others wait for a full year, and there are some that switch to less frequent protocol as soon as they hear that tests got normal. Still, we should suggest not jumping off so fast and keeping the protocol you are having now for at least half a year. This is our personal – not professional—opinion, and we can not support it with robust studies.

          1. William

            thank you for the response. I share your bias and was leaning towards decreating the frequency to 3 days a week after a year (next Sept).

          2. Fenbendazole.org

            Sounds like a solid plan, William. Giving it a full year before switching to 3 days/week seems like a cautious and wise approach. Wishing you continued great results!

  138. Barbara

    My mom was diagnosed with MDS 20 years ago and was basically asymptomatic for the first 19. In the last 10-12 months, due to low HGB levels, she has been on full-time oxygen and getting regular transfusions. In March, her doctor switched her from every-other-week Darbepoetin shots (which were having no apparent effect) to every-three-weeks Rebolozyl shots. This definitely reduced the frequency of her transfusions while she maintained an HGB count in the 7s for a few months. However, throughout September, her numbers dropped much more quickly after both a shot and transfusion. Her doctor found leukemia cells in her blood which apparently helps to explain this. She had some Ivermectin on hand so took 6 mg of that today. I am also interested in the potential benefits of Nattokinase and Fenbenzadol. I would be grateful for your recommendations as it isn’t something her doc will likely recommend. Thanks in advance!

    1. fenbendazole

      Dear Barbara,
      Yes, Fenbendazole has shown potential benefits in various cases and could be worth considering for your mom. Many people have reported positive outcomes when incorporating Fenbendazole into their treatment regimen, especially for cancer-related conditions. Given that her condition has progressed and leukemia cells have been found, adding Fenbendazole might provide additional support alongside her current treatments.
      Nattokinase is also known for its potential benefits in improving circulation and reducing blood clots, which could be helpful for her overall health. Since her doctor might not recommend these alternative treatments, it is always best to carefully monitor her condition while exploring these options.

  139. Debbie

    Hello
    Im a bit confused, Im looking for a dosage for my 22kg dog with mammory gland cancer and a liver mass, but its working out double the mg of a human. I thought dosages were lower in dogs than humans?

    1. fenbendazole

      Dear Debbie,
      I understand that there may be some confusion regarding the appropriate dosage of fenbendazole for dogs. The recommended dosage is indeed based on body weight, and it is not uncommon for the dosage to be higher in dogs compared to humans due to differences in species metabolism.
      For a dog weighing 22kg, the typical dosage is 444mg per day. Although this may appear higher than the standard 222mg dose often prescribed for humans, the increased dosage is necessary due to metabolic differences and remains within the safe therapeutic range for dogs.
      However, it is always advisable to consult with your veterinarian to ensure the correct dosage for your dog’s specific condition, particularly given the presence of mammary cancer and a liver mass.

  140. Brandon

    Hi Joe, I have a 3cm hard and fixed lump in my neck, I have just been for a specialist examination of the lump and I am scheduled for an urgent ultrasound scan in 2 days. They will probably need to do a biopsy as well. If it does turn out to be cancer (as I suspect), would it be wise to have surgery in an attempt to remove the lump and then start the Fenben protocol, or should I start the Fenben protocol upon diagnosis of cancer? In the event the cancer may have spread to other areas in my body, wouldn’t it make more sense to treat the whole body with the Fenben protocol, rather than the localized infected lump that the surgeon would remove?

    Thank you for any help/advice you can provide.

    1. fenbendazole

      Hello Brandon,
      if the lump turns out to be cancer, it is definitely a personal decision, but many people choose to start the Fenbendazole protocol right away, whether they opt for surgery or not. Starting the protocol immediately can help address any potential spread of the cancer throughout the body, not just the localized lump.
      Surgery can remove the lump, but if there is any risk of the cancer spreading, using Fenbendazole alongside can help target the whole system. It might be a good idea to combine both approaches—surgery to remove the lump and then the Fenbendazole protocol to treat any possible remaining cancer cells.

  141. Susan

    Can one combine hormone blockers for breast cancer, f.e.x Tamoxifen, with a fenbendazole treatment ?

    1. fenbendazole

      Dear Susan,
      Yes, it is possible to combine hormone blockers like Tamoxifen with Fenbendazole. Many individuals have incorporated Fenbendazole into their treatment plans while using medications like Tamoxifen for breast cancer. However, as with any combination of treatments, it is important to closely monitor your body and how it responds. Many have found success with this combination without issues. Just ensure you are following the recommended dosages for both treatments.

  142. AZ Ray

    I was recently diagnosed with stage IV mantle cell lymphoma throughout the body and in the bone marrow. I started taking the 444 mg dosage with supporting supplements 6 days ago. Can I continue this daily without a stoppage or do I need to take a break? Is there a limit to the amount of time to continue this? My oncologist will be monitoring with blood draws and PET scan at appropriate intervals. Thank you in advance.

    1. fenbendazole

      Hello,
      Yes, you can continue taking Fenbendazole at the 444 mg dosage 6 days a week with one day off. This protocol can be followed continuously until you reach No Evidence of Disease (NED). It is crucial to monitor your liver enzyme levels regularly during this period, as Fenbendazole is metabolized in the liver. If your liver enzymes remain within normal limits, it should be safe to continue.
      Since your oncologist will be monitoring your progress with blood tests and PET scans, you will have good oversight of your overall health.

  143. Esther

    Hi, will this protocol work for benign tumours, specifically uterine fibroids?

    1. fenbendazole

      Dear Esther,
      There is no well-documented evidence or clinical trials showing that fenbendazole or similar protocols are effective in treating benign tumors, such as uterine fibroids. Most of the available studies and reports on fenbendazole focus on its potential to fight malignant cancers, not benign growths like fibroids.
      However, since uterine fibroids can still cause significant symptoms, it may be worth considering alternative treatments. Although fenbendazole’s potential mechanism—such as disrupting microtubule formation in cancer cells—has been studied primarily in malignant contexts, it is possible these effects could also offer benefits for benign conditions. This is speculative at this point, though, and there is no solid evidence supporting its use for fibroids.
      If you decide to explore this option, it is crucial to regularly monitor your overall health, conduct blood tests, and keep track of liver enzyme levels.

      1. boomer

        i only have the liquid 10% suspension fenbendazole. what would be dose for a 330 lb. man?

        1. fenbendazole

          Hello,
          Based on your body weight of 330 lbs (approximately 150 kg), the recommended Fenbendazole dosage is 444 mg per day. Since you have the 10% suspension of Fenbendazole, the concentration of the active ingredient is 100 mg per milliliter (ml) of the suspension.
          To achieve the 444 mg dose, you will need to take 4.44 ml of the liquid suspension daily.
          This is the amount you should take daily. Be sure to follow the protocol of 6 days on and 1 day off if you are using Fenbendazole as part of a cancer treatment regimen. This break allows your body time to rest and metabolize the medication effectively. Regular monitoring, particularly of liver function, is also advised during prolonged use.

    Hi, we live in Australia, my wife has had breast cancer stage one grade 3. We only have liquid Fenbendazole active constituent 25g/L. Oral Anthelmintic for sheep goats and cattle. Could you tell me how much of that liquid concentration is equivalent to your dosage calculator? Body weight is 62 kilo or 136 lbs

    1. fenbendazole

      Hello John,
      to reach the recommended dose of 222 mg of fenbendazole for your wife, she would need to take about 8.88 mL of the liquid formulation.

  145. Kris

    Hello, my mother in law was diagnosed with stage 3 bladder cancer, she got it removed but it has already spread. We originally purchased the 440 mg capsules when she was first diagnosed because that was the recommended dosage for her weight. She didn’t start taking it though. Now she wants to start but has lost a lot of weight and is now down to 72 kg which has the recommended dosage of 220 mg. Is there any good way to adjust the frequency for 440 mg capsules instead of 220 mg, or should we just keep the same frequency recommendations with the original dose of 440 mg? Also do you happen to know if it is generally safe to curcumin and milk thistle while on blood thinners? She has blood clotting problem and needs blood thinners, and I know the Fenbendazole doesn’t react with blood thinners but I heard the curcumin and milk thistle may. I wasn’t sure how important they were for the protocol, or if there are many people who did/didn’t experience problems taking them with blood thinners.

    1. fenbendazole

      Hello, Kriss, thank you for a question.
      We would recommend taking 222 mg according to her weight. Only if you make sure her blood work is good and liver enzymes are at normal range – you may try to increase dosage. Milk thistle is generally considered safe, but the interaction with blood thinners is less well-documented than curcumin. Curcumin has blood-thinning properties, which could potentially increase the risk of bleeding when taken alongside blood thinners like warfarin, aspirin, or others. This can enhance the effect of the medication, making the blood too thin.

      1. Owen

        “Since CBD oil is unavailable in our country, would it be advisable for me to instead consider taking fenbendazole and curcumin for breast cancer

        1. fenbendazole

          Hello Owen,
          Certainly, if CBD oil is not accessible, adding both fenbendazole and curcumin to your breast cancer treatment plan could be worthwhile. Both substances have been studied for their potential impact on cancer cells, with curcumin particularly recognized for its anti-inflammatory and antioxidant properties. For optimal absorption, it is recommended to take curcumin with a fat source and black pepper (piperine).

      Dear Jimmy,
      Before using any product, especially those intended for animals, it is important to verify the correct dosages for human use. While both ivermectin and fenbendazole have been used in humans, animal formulations can differ in concentration and purity, so caution is essential.
      For fenbendazole, the standard human dosage for deworming is about 222 mg per day for individuals under 180 lbs, or 444 mg per day for those over 180 lbs. Based on the product you purchased (4 grams of fenbendazole), you should divide it carefully to match these daily dosages. For example, if you weigh 180 lbs or more, 444 mg would be the appropriate daily dose, meaning that 4 grams would last approximately 9 days.
      Regarding ivermectin, the human dosage can vary, and it is important to use the right concentration. We primarily focus on fenbendazole, so we do not have specific information on ivermectin dosage. Please proceed with caution and consult a professional before using it.
      In general, when using animal products, be cautious, as they might contain additives or concentrations not suited for human use. It is always best to choose products without additives designed specifically for animals.

    Hi, I’m seeking advice regarding the use of fenbendazole as a complementary treatment. My mum has been diagnosed with metastatic breast cancer, and she is going to be taking Fulvestrant (Faslodex) as part of her treatment plan.(unable to take other meds due to inability to swallow pills for medical reasons).

    I’ve read about potential benefits of fenbendazole, but I’m concerned about its safety in combination with Fulvestrant, as well as its impact on liver health, since my mum has liver metastases and I understand that fenbendazole is metabolized in the liver.

    She’s already taking milk thistle and curcumin as part of her protocol to support liver health, but I want to ensure that it’s safe for her to take fenbendazole alongside these treatments. Could you provide any insight or guidance on how these might interact?

    Thanks for your time and help.

    1. fenbendazole

      Hello Rachel,
      The specific interaction between Fulvestrant (Faslodex) and fenbendazole has not been extensively studied, but both drugs are primarily metabolized in the liver, which raises potential concerns regarding liver function and drug interactions. Given that your mother has liver metastases, her liver is already under strain, and introducing fenbendazole, which is also metabolized by the liver, could increase the risk of altered liver function.
      Combining these two treatments might affect the way either drug is processed, potentially reducing their effectiveness or increasing the risk of side effects. Since Fulvestrant relies on liver metabolism, any additional liver stress from fenbendazole or other supplements may complicate her treatment.
      Close monitoring of liver enzymes (such as ALT, AST, and bilirubin levels) will be crucial if fenbendazole is added to her regimen. This will help assess liver function regularly and detect any early signs of liver stress or drug interactions.

    Hi, lung cancer, no more details yet, waiting for CT appointment. Want to start with the protocol right away. Do you have to follow a specific order when taking Fenbendazole, CBD, Curcuma, etc.? I have already everything at home (in capsules, Fenben 222mg according to my weight of about 58 kg) except Quercetin capsules – they arrive on Monday. Thanks in advance for information. Bless you

    1. fenbendazole

      Dear Gerda,
      It is great that you are ready to start the protocol and that you have already gathered the necessary supplements. The dose and schedule of fenbendazole are indeed very important for ensuring effectiveness and safety. You have chosen the correct dose of 222 mg based on your weight of 58 kg, which is ideal. As for the schedule, it is recommended to follow a regimen of 6 days on, 1 day off for optimal results.
      You can also double-check your dosage with the dosage calculator at https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/, where you will find additional guidelines on how to use fenbendazole and other supplements like CBD and curcumin. There are also recommendations for supplement dosages that may be helpful to ensure you are on the right track.
      It is advisable to take fenbendazole in the first half of the day, preferably with or after food, as this can aid in absorption and effectiveness. Once your Quercetin capsules arrive, you can integrate them into the protocol seamlessly. Best wishes on your journey, and do not hesitate to monitor how your body responds to this regimen. Blessings to you.

    Do know you if fenbendazole can be taken with apocaps in a canine? Maybe do the apocaps on the four off days?

    1. fenbendazole

      Dear Summer,
      Thank you for your question. Although there is not extensive formal research on combining Fenbendazole and Apocaps in canines, many dog owners have tried using both as complementary treatments. It is possible to use them together, but as with any combination of treatments, it is essential to proceed cautiously and monitor your dog’s overall health, including liver enzyme levels.
      Administering Apocaps during the off days when Fenbendazole is not given could be a sensible way to prevent overwhelming your dog’s system.

      1. Věra

        Hello, my friend had a brain tumor Glioblastoma IV. He has undergone surgery in January 2025, after chemotherapy and radiation. Now he is clear after an MRI. I started giving him 500 mg of menbendazole for four days in A week. Should I add Ivermectin? He takes vitamin C, D Turmeric

        1. Fenbendazole.org

          Hello Vera,
          Your friend’s current MRI result is very encouraging. The regimen of 500 mg of mebendazole taken four days per week, which you specified, is consistent with protocols some caregivers use in the period following surgery, chemotherapy, and radiation, provided it remains well tolerated.
          Regarding ivermectin – some families and caregivers do explore it, but we cannot provide specific direction on whether it should be added, as our platform focuses on fenbendazole information and not on designing combination protocols.
          Since you are actively supporting a person recovering from an aggressive tumor, many caregivers also research sodium dichloroacetate (DCA) because it works through cellular metabolism rather than cytotoxic mechanisms, creating a different type of metabolic pressure on cancer cells, which is why it is often considered when people look for non-DNA-damaging adjunct approaches.

    2. Mirjam

      I have a question, my mom had 2 heavy chemo + radiation treatments that did nothing for her lung cancer. The protocol looks confusing: 1 says 3 days on 4 days of. The other 6 days on 1 day of. And another says take daily?
      And how long should we follow this regime? Untill it is gone and then go on to the maintenance dosage? Also she is on blood thinners wich can not be used with curcumin. Will this affect the whole treatment?

      1. fenbendazole

        Hello Mirjam,
        The protocol can seem confusing because of the different schedules people follow. However, leaving out curcumin due to your mother’s blood thinners won’t significantly affect the protocol’s effectiveness. While curcumin is commonly used for its anti-inflammatory properties, fenbendazole is the main focus, and the protocol remains effective without it.
        As for dosing, most protocols suggest:
        – 3 days on, 4 days off for cancer prevention in those without cancer;
        – 6 days on, 1 day off for individuals with active cancer;
        – or daily use for more aggressive cancers.
        You can find a detailed dosage guide and calculator at https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/ to help with dosing based on body weight and additional insights.
        Regarding how long to stay on the regimen, many continue until there is noticeable improvement or the cancer is under control, then transition to a maintenance dose.

  150. Jeff

    Hi there, thanks for offering suggestions on use of Fenbendazole.
    If I suspect my 60 lb dog has cancer, per the dosage calculator its 444MG, 4 days On, 3 Days Off. Is there a reason why its not a full 6 days On like Human, or even some Human take 7 days On with no breaks. I know there are Liver concerns, which I do give my dog Milk Thistle. I am just worried the suggested 4 days On, 3 days Off might not give him all he needs … any more suggestions is appreciated. My dog is age 10 yrs. Thanks.

    1. fenbendazole

      Hello Jeff,
      Thank you for your question and for considering the use of Fenbendazole for your dog. The recommended 4 days on, 3 days off dosing schedule for animals, including dogs, is designed to balance effectiveness with minimizing potential liver stress and other side effects. The metabolism of Fenbendazole differs between humans and animals, and dogs may process the drug at a different rate, which is why the dosing protocols are adjusted for their needs.
      The 4 days on, 3 days off regimen allows for a break in the treatment to support liver function and recovery. This is particularly important in older dogs, like your 10-year-old, to prevent overloading the liver. It is great that you’re already giving your dog Milk Thistle for liver support, which can be helpful during this treatment.
      If you are concerned about whether this regimen is providing enough treatment for your dog, it is always best to consult with a veterinarian who has experience with Fenbendazole protocols in cancer treatment. They can provide additional guidance tailored to your dog’s specific condition and health needs.
      We hope this information helps, and thank you for reaching out.

        How do you measure a dose for a human with Safe-Guard Fenbendazole Equine Dewormer Paste?

        1. fenbendazole

          Dear Missy,
          To measure a dose for human use with Safe-Guard Fenbendazole Equine Dewormer Paste, it is crucial to calculate based on body weight, as the paste is designed for animals and contains concentrations suitable for equine dosing. Typically, a standard human dose is around 222 mg of fenbendazole. Since equine paste often has fenbendazole at a concentration of 10% (100 mg per gram), you would measure out approximately 2.2 grams of paste to reach the 222 mg dose, though it is best to confirm the exact concentration on the product packaging.

    Is it ok to take Fenbendazole and Ivermectin together? Should i cut the dosage of each in half?

    1. fenbendazole

      Hello,
      It is generally considered safe to take fenbendazole and ivermectin together because there is no well-documented evidence of harmful interactions between the two. However, there is no need to halve each dose unless specifically advised by your healthcare provider.
      If you are following a specific protocol, it is usually best to stick to the recommended dosages for each drug.

      1. Breauna

        Hello Fenbendazole, I wasn’t sure how to ask a question in this comment thread so I just hit reply, my apologies.
        My cat is 17 years old and has hyperthyroidism and a history of pancreatitis and stomatitis. Within the past year I have noticed a few lumps appearing on his body and I am concerned that maybe he has cancer. Since fenben doesn’t seem to have any severe side effects I am considering ordering some and giving it to my cat just in case (and as a bonus it would rid him of any parasites too!). I just used the dosage calculator and it is telling me that I should give 333mg to my 11 pound cat but it says that if I was taking it for cancer that I should take 222mg (I am 108 lbs). This doesn’t sound right to me that I would give my cat a larger dose than I would give to myself. Is the dosage calculator broken or is this actually correct? How many days should I give it to him? Thanks for any advice and information.

        1. fenbendazole

          Hello Breauna,
          Thank you for reaching out with your question. The difference in dosage between animals and humans is primarily due to the variations in metabolism. Cats and humans process medications differently, so it is common for animals to require doses that might seem larger in comparison to humans, even if their body weight is similar. This difference is based on how each species metabolizes and clears drugs from the body.
          The dosage calculator is working correctly and has calculated the appropriate dose for your 11-pound cat. It takes into account species-specific metabolism and the specific requirements of animals, which can result in a larger dose compared to humans. This is why the suggested dosage for your cat may appear higher than what would be prescribed for a human of a similar weight.
          As for how many days you should give the fenbendazole, it is essential to consult with a veterinarian, especially given your cat’s history of hyperthyroidism, pancreatitis, and stomatitis. A vet will be able to provide specific guidance on the duration and safety of fenbendazole treatment in your cat’s case.
          We hope this helps, and please feel free to seek further advice from your veterinarian to ensure the best care for your cat.

  152. Steve

    Taking 444mg fenben per day. Taking 4mL of liquid ivermecton a day. 3-4 apricot seeds.

    Side effects: a bit woozy, don’t type as tell, sleepy, a little clumsy.

  153. Cheryl DD

    Hello, First off I wanted to say I appreciate that you answer people’s questions!…I have breast cancer, and the doctor said it is small and they are going to do a lumpectomy and radiate it and everything should be fine. My question is…Is it absolutely necessary to take the other supplements? Can I just take the Fenbendazole and will it work the same way? I don’t have much money so I can’t afford to buy everything. I already take Choline for my liver(fatty liver), I also take a Silymarin Complex that has Milk Thistle Extract and Dandelion plus other stuff in it. I also take a Gallbladder Formla. I weigh 233 so your calculator said to take 444ml of Fen. Thank You.

    1. fenbendazole

      Dear Cheryl,
      Thank you for your question, and we are glad to hear that your doctor has a solid plan for your treatment. It is perfectly understandable to be concerned about the cost of supplements. The good news is that you can take Fenbendazole on its own along with the supplements you are already using. The Choline, Silymarin Complex, and Gallbladder Formula you are taking are great for supporting your liver, especially since you mentioned having a fatty liver.
      While additional supplements can sometimes be beneficial, they are not strictly necessary. The most crucial part of the protocol is the Fenbendazole itself. Based on your weight and condition, you should take 444 mg of Fenbendazole daily with food, six days a week, with one day off.
      If you have any more questions or need further guidance, please feel free to reach out. We are here to support you on your journey. Take care, and we wish you the best with your treatment.

    What would be a good regimen for someone who has rhabdomyosarcoma that started in the kidney, which the kidney was removed but it metastasized in the same area afterwards, looking for dosage or anything else that would help, also should the person not take fenbendazole the day prior the day of and the day after their chemo/radiation, the person weighs less than what your dosage calculator goes to

    1. fenbendazole

      Dear Chris,
      If the patient weighs less than 45 pounds, we do not advise using Fenbendazole or other off-label drugs. However, if you choose to administer Fenbendazole to a patient of this weight, it is crucial to closely monitor the patient’s overall well-being and regularly check liver enzyme levels. The maximum dosage for a child under 45 pounds should not exceed 111 mg. In terms of combining Fenbendazole with chemotherapy or radiotherapy, it is essential to discontinue Fenbendazole two days before, during, and for two days after the chemotherapy or radiotherapy sessions.

      1. Chris

        Also what’s the difference between the two other than one is for animals and the other is for humans

        1. fenbendazole

          Both mebendazole and fenbendazole belong to the same class of drugs called benzimidazoles and work similarly by disrupting cellular functions in parasites, which can lead to their death. This similarity has led to interest in their off-label use, including in cancer treatment. The main difference is accessibility: mebendazole is intended for human use and typically requires a prescription, making it harder for some patients to obtain, especially if their doctor is not familiar with its off-label use. Fenbendazole, however, is sold over the counter for veterinary use, particularly for animals like dogs and horses, which makes it easier to obtain without a prescription. This accessibility is why many people choose fenbendazole when exploring alternative protocols. In short, both drugs work the same way, but fenbendazole is easier to get, making it a popular choice for those seeking alternative treatments.

        2. Lola

          My Husband has been diagnosed with Squamous cell carcinoma of the right neck, P16 positive. He has been taking 100 mg Mebendazole daily for about 3 weeks, prescribed to take for one month and then alternate monthly with Doxycycline.
          Would it be more beneficial to switch to the Fenbendazole 222mg 6 days on one day off protocol? It has grown in his most recent scan (before starting the Mebendazole) so we want to hit it as hard as possible. He is taking curcumin and other natural supplements alongside. Thank you.

          1. fenbendazole

            Dear Lola,
            Yes, it could be worth switching to the Fenbendazole 222mg protocol (6 days on, 1 day off). It is possible that 100mg of Mebendazole was too low of a dose to have a strong impact on the cancer. Many people have seen positive results with Fenbendazole, and it could be a good option for hitting the cancer harder. Alongside the curcumin and other supplements, Fenbendazole might help support his fight. It is definitely worth giving it a try.

  155. Jeff

    Hello,
    Are their supplements that should not be taken with Fenbendazole? Meaning those supplements might counteract the good effects that Fenbendazole could have in treating cancer? For instance, would taking NAC cause a negative impact on how Fenbendazole’s impacts cancer treatment outcomes? Thanks

    1. fenbendazole

      Hello Jeff,
      There is no definitive evidence that taking NAC or other supplements would counteract Fenbendazole’s potential anti-cancer effects. However, given the theoretical concerns, it might be prudent to avoid high doses of antioxidants like NAC while using Fenbendazole for cancer treatment, at least until more conclusive research is available.

  156. Ian Smith

    I’m going to start a fenben protocol and I was guided here from Twitter. There seems to be a debate about this protocol vs the contrabandcures protocol. That protocol would have me take 5.4 GRAMS of Fenben a day for two weeks and then switch to Ivermectin. The reasoning for the high amount of Fenben seems to be the Merck’s manuals suggested dose for Simians being 50mg/Kilo.
    Do you have any thoughts on this ?
    https://www.merckvetmanual.com/multimedia/table/nonhuman-primate-therapeutics

    1. fenbendazole

      Hello, Ian and thank you for the question!
      Hello, this high of a dose might be effective only against worms if used for short period of time to “bombard” worms inside your body (liver will be effected – but should recover). If we are talking about cancer – this is not a sprint. We do not recommend using more then 444mg a day. At least if you want to use bigger doses, be sure to monitor your liver enzymes. Stay safe!

  157. Mario

    Hi.
    the following treatment (3 weeks later), is that 21 days counting from day 1 of taking fenben (parasite treatment for humans) or 21 days from the last day (5th day) of treatment?

    1. fenbendazole

      Hello Mario,
      The 21-day period typically starts counting from the last day of treatment (the 5th day). So, after completing the 5-day course, you would wait 21 days before starting the next cycle. This allows your body some time to process the treatment before the next round.

    Quick question: does fenben work like ivermctin to reduce flues and viruses?

    1. fenbendazole

      Hello, Bob, and thank you for a question.
      No, fenbendazole is an antiparasitic medication used primarily for animals and is not known to reduce flues and viruses. Ivermectin, while also an antiparasitic, has been studied for antiviral properties.

  159. garyZ

    I have started taking fenbendazole (2.22 grams of a Panacur 10% (100mg/g) viscous creme horse dewormer.

    I am taking this for a familial genetic condition (succinate dehydrogenase “SDHD” gene mutation) that causes tumors (pheochromocytomas that can secrete adrenal hormones and paragangliomas that are nonsecretory). I have tumors in my adrenal glands and in my neck.

    This is not the same thing as a cancer, though these tumors can rarely go metastatic. But since the tumors are not genetically distinct from any of the other cells in my body, they cannot be treated as most cancers, that are unusual growths with distinctly mutated DNA. I am wondering if there is any evidence you know of of the efficacy of fenbendazole against these non-cancerous tumors. (I doubt it, because this is a pretty rare genetic condition, but I will try to report back after a couple of months, when I hope to get new imaging studies that will show if the tumors have changed in size.)

    1. fenbendazole

      Dear Gary,
      Some people are studying the possible effects of Fenbendazole on various diseases, including non-cancerous tumors. Although there is not much evidence for conditions such as a mutation in the SDHD gene, it is interesting to see how this may affect tumor behavior.
      Since you are starting this treatment and plan to monitor changes with imaging, this is a great way to monitor any possible effects. It is always interesting to see how different treatments can work in unique situations.

  160. Luis Rojas

    Can fenbendazole be used to treat hepatitis C ?

    Thanks in advance

    1. fenbendazole

      Hello, Luis!
      Thank you for the question.
      There is no substantial scientific evidence supporting the use of fenbendazole for treating hepatitis C.
      Hepatitis C is a viral infection that primarily affects the liver. The standard treatment involves antiviral medications specifically designed to target the hepatitis C virus (HCV). Direct-acting antivirals (DAAs) are the current standard of care and have been shown to be highly effective in achieving sustained virologic response (SVR), which means the virus is no longer detectable in the blood.

      Hello, Ka, and thank you for a question.
      We no longer provide suppliers list, since there are so many new ones now. Fenbendazole got really popular and many new brands have been created. We for can recommend Panacur or Safeguard for sure, since they are FDA approved. There are lots of other independent companies that can supply fenbendazole. You may want to do your research on them. Be sure to check brands on trustpilot and Amazon reviews to form a better supported opinion.

  162. Christy

    My mom has been on Joe Tippins protocol for about a month but has a new tumor. Is this normal? I’m afraid it’s not working.

    1. fenbendazole

      Hello Christy,
      Fenbendazole, depending on the patient’s response to treatment, generally begins to work somewhere after 2-4 months of use. It might still be too early to determine its full effectiveness.
      It is also important to ensure that the correct dose and schedule are being followed. You can use the calculator available at this dosage guide: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/ to verify the dosing.
      Another factor to consider is the quality of the fenbendazole. Make sure you are purchasing it from a reliable supplier, as poor quality medication can affect treatment outcomes.

      Добър вечер!
      Баща ми е диагностициран с метастатичен рак преди 2 седмици в белите дробове и в мозъка, като казаха, че е 4-ти напреднал стадий. Мозъка е най-засегнат там са 6-7 на брой като най-големия е 3,8-9 мм, което е почти 4 см. Към момента приема поддържащи лекарства от научаването на болестта, които са: Дексаметазон 4 мг хапчета, Нолпаза 20 мг и Левебон 500 мг. Подложихме го и на малка доза с лъчелечение насочено към мозъка и на следващия ден с ударна доза лъчелечение преди 5 дена. След лъчелечението са вливали банка Манитол и са предписани инжекции Дексаметазон по схема. Откриха, че заболяването е рак след като му отказаха дясната ръка и крак. Има усет, но са обездвижени, не помръдват. Говора също е засегнат като към момента има подобрения в говора и вече свързва 3-4 думи в изречения.
      Въпросите ми са:
      Дали в неговото състояние може да приема това лекарство и след колко време да очакваме някаква реакция на организма му?
      Дали е съвместимо лекарството с неговите лекарства и лечения, на които е и бил подложен?
      Други витамини или добавки, които може да засилят ефекта, които да добавим?
      Дали би могло да помогне към текущите лечения и да му се помогне с приема на това лекарство?

      1. fenbendazole

        Good day.
        We are very sorry for such a serious condition of the patient. Fenbendazole can have a positive effect, but it is difficult to say whether the effect will be optimal, since the disease has already progressed significantly. You can still try, but keep in mind that one of the most common side effects of fenbendazole is stress on the liver, so monitor your liver enzyme levels. However, it is really difficult to boldly claim that fenbendazole can cure the disease at such a severe stage.
        You also asked how long till the effect can be expected; the response to the protocol is quite individual. Some experience the first effect after a couple of weeks – others only after a couple of months. However, it is a relatively safe preparation, so it should be well tolerated if the liver is in good condition.
        Best of luck.

  163. Meri

    Good evening,

    My husband has been using fenbendazole (Fenben Labs powder) since this past May and I’ve noticed a progressive increase in his eosinophil count since approximately three weeks after beginning it. In your experience, is this normal with fenbendazole use?

    Thank you,
    Meri

    1. fenbendazole

      Dear Meri,
      Fenbendazole, which is often used to treat parasitic infections, can occasionally lead to side effects. One such side effect can be an increase in eosinophil counts. Eosinophils are a type of white blood cell involved in combating parasites and allergic reactions. The progressive increase in your husband’s eosinophil count since starting fenbendazole may be his body’s response to the medication or the parasites it is targeting. This rise could be due to an allergic reaction to fenbendazole or as part of the immune system’s activity against the parasites being eradicated.
      Additionally, if a person has cancer, an increase in eosinophil counts can also be associated with the disease or its treatment. Cancer can cause various changes in blood cell counts, including eosinophils, due to the body’s altered immune response.

  164. David

    Hi,
    Just found this site. I have been battling prostate cancer for 5 years. Six months ago started taking Fenben in liquid form (Merk Safe-Guard for Cattle/Goats) While reading the comments/Questions someone said that there are fillers in this particular version of Fenben that could exacerbate hormone driven cancers such as prostate cancer. I did a search and this is the only place I have seen that. Also could not find any resource that listed fillers in the liquid form. I chose this form as it is much cheaper and easier to use but am wondering if I should switch to the granules instead. Any additional information would be greatly appreciated.

    1. fenbendazole

      Hello David,
      We are glad you found this site and are looking into the different prostate cancer treatment options. Concerns about liquid Fenben (Merk Safe-Guard for Cattle) fillers that may affect hormone-driven cancers such as prostate cancer are well-founded. However, it is important to note that specific information about this liquid form of fillers may not be widely documented.
      Switching to a pellet form can give you more clarity and more control over what you ingest, as it typically contains fewer additives. Consulting a health care professional with expertise in both traditional and alternative therapies can provide valuable insights tailored to your situation.
      Best wishes on your journey to better health.

  165. Anouk Raaphorst

    Can you explain what the difference is between Mebendazole and Fenbendazole?
    How come the Fenben are 222mg tablets and the Mebendazol 100mg tablets?

    1. fenbendazole

      Dear Anouk,
      Mebendazole and fenbendazole are both anthelmintic medications with distinct uses and dosages. Mebendazole is commonly prescribed in human medicine to treat intestinal worm infections caused by parasites such as roundworms, hookworms, whipworms, and pinworms. It works by inhibiting parasites’ ability to absorb glucose, leading to their elimination. In contrast, fenbendazole is primarily used in veterinary medicine to treat various parasitic infections in animals, including roundworms, hookworms, whipworms, and certain tapeworms. The difference in tablet strengths—222mg for fenbendazole and 100mg for mebendazole—reflects the varied dosing needs between animals and humans, as well as the specific parasites targeted.
      Beyond their traditional uses, both medications have sparked interest in cancer therapy as adjunct treatments. Mebendazole has been studied for its potential to disrupt microtubule function in cancer cells, which could inhibit tumor growth. Some preclinical studies and reports suggest it may also enhance the effectiveness of conventional cancer treatments like chemotherapy. Similarly, fenbendazole has shown promise in laboratory studies for its ability to induce apoptosis in cancer cells by interfering with microtubule dynamics. Although research is still in its early stages, there is growing interest in exploring these medications’ potential roles in cancer treatment.

    Hello there, my mom has stage 4 metastatic breast cancer now spread to her liver and she hasn’t and doesn’t want to take chemo.
    She is 55 years old and i would like to know if is it safe for her to take fenebendazol because her liver enzymes are very high (alt,ast and gamma gt). What can we do to lower them or what dose what suit her? Thank you!

    1. fenbendazole

      Given that your mother’s liver enzymes (ALT, AST, and gamma GT) are significantly elevated, it suggests that her liver might be under stress. In such cases, it is important to avoid medications or substances that could potentially further burden the liver, such as fenbendazole, which is metabolized in the liver. Instead, we recommend considering supportive measures that can help improve liver health and potentially alleviate symptoms, such as milk thistle. Milk thistle is known for its liver-protective properties and is widely used to support liver function due to its antioxidant and anti-inflammatory effects.
      Additionally, adopting a healthy diet rich in fruits, vegetables, whole grains, and lean proteins can further support liver health. It is advisable to avoid alcohol and reduce intake of processed foods and saturated fats. Ensuring she stays hydrated by drinking plenty of water can help flush toxins from the body and support overall liver function.
      Regular monitoring of her liver enzyme levels is crucial to assess any changes and adjust treatment accordingly. We understand this is an incredibly challenging time for your family, and we hope these suggestions can provide some guidance and support for your mother’s well-being. If you have any further questions or concerns, please feel free to reach out.

    Hello,
    What would the dosage be for powdered Fenbendazole
    It says: 120 X 222mg
    Thank you.

    1. fenbendazole

      Dear Azul,
      The dosage of Fenbendazole powder can be determined by considering the concentration of the powder. The label “120 x 222 mg” typically signifies that there are 120 packets of Fenbendazole powder, with each packet containing 222 mg of Fenbendazole.
      In simpler terms, each packet contains 222 mg of Fenbendazole. To determine the appropriate dosage for your needs, please use our dose calculator, available here:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      If you have any additional questions, please do not hesitate to ask.

      1. M Diane

        I’ve seen some protocols recommending 50mg/kg of fenbendazole. Can you comment on that? Is that dangerous ?

        1. fenbendazole

          50 mg/kg can be dangerous. Fenbendazole is considered relatively safe, but in such doses it is most likely to harm liver if used for a longer periods. For deworming this might be okay, since usage is not as prolonged, but for cancer it can damage liver.

  169. Yael

    Hi
    Are hot flashes a side effect of fenbendazole or a cleansing effect of the cancer cells?

    1. fenbendazole

      Hello Yael,
      Hot flashes are typically not linked to fenbendazole usage. Moreover, there is no scientific evidence supporting the idea that hot flashes have a cleansing effect on cancer cells. These flashes are commonly associated with hormonal shifts, particularly during menopause, but can also stem from other factors such as medications, infections, or specific medical conditions.
      It is important to discuss hot flashes with a healthcare practitioner if you or someone you know is experiencing them while undergoing cancer treatment. They can identify the underlying cause and, if needed, offer suitable management or further assessment.

  170. Claude Trump

    Hello Person Answering these question(s),

    I’ve had horrible side effects from dual radiation treatments (EBR and seeds) for stage 1B intraductal cancinoma in my prostate. I’ve been hospitalized 6 times over the last 3 years with fistulas spreading to my buttock from radioactive seeds exploding out from my prostate due to an abscess;; Kidney failure and then TURP surgery with 8 UTIs and penile stricture removal from catheter damage. Now my PSA is creeping up again and before I go crazy with the urologist/radiation oncologist/reconstructive urologist… I was wondering if you think Fenbendazole could help me? If so, should I do the original protocol with the added CBD…? What brands should I use? Do you know if this would interfere with Myrbetriq, metoprolol, rouvastatin or acyclovir? Thank you and sorry for the long winded questions!

    1. fenbendazole

      Hello Claude,
      Thank you for your inquiry. Fenbendazole may offer potential benefits in your situation. It has demonstrated effectiveness against various types of tumors; however, its efficacy can vary based on factors such as the patient’s immune response, overall health, the aggressiveness of the cancer, and individual treatment responses. Therefore, predicting how Fenbendazole will specifically work in your case is challenging.
      Regarding drug interactions, Fenbendazole is generally considered to have minimal interactions with other medications such as Myrbetriq (mirabegron), metoprolol, rosuvastatin (not rouvastatin), and acyclovir. These medications operate through different mechanisms and are metabolized differently, thereby reducing the risk of significant interactions. Nonetheless, it is advisable to proceed with caution. If you decide to incorporate Fenbendazole into your treatment regimen, do so gradually. Regular blood tests and monitoring of your overall well-being will help detect any potential adverse effects promptly.
      We recommend using our dose calculator, selecting “Cancer” under the “Fenbendazole for” section, and choosing “Cancer treatment” in the “Protocol” section. The calculator will determine the appropriate dose and schedule based on your body weight. It also provides guidance on supplementary measures that can complement the protocol. Please note that while supplements can be supportive, they are not the primary component of the protocol. Omitting or adjusting supplements should not significantly affect the efficacy of Fenbendazole.
      Should you have any further questions, please feel free to reach out to us. We are here to assist you.

      1. Cheryl Purdy

        I was wondering why the dosing of Fenbendazole for a cat is 4 days on, 3 days off?

        1. fenbendazole

          Dear Cheryl,
          The dosage schedule for Fenbendazole in cats has been carefully planned to account for the special biological characteristics of feline metabolism.
          It seeks to achieve a balance between effectiveness and safety, taking into consideration how cats process and remove medications.
          The regimen of administering Fenbendazole for 4 consecutive days followed by 3 days without treatment is meticulously chosen to enhance its effectiveness against cancer while reducing the likelihood of adverse effects or toxicity. This approach ensures that the cat’s metabolism can efficiently process and eliminate Fenbendazole during the off-days, thereby preventing the accumulation of potentially harmful levels.

        2. Carmine

          Will fenbendazole help me with Polycythemia Vera? My phlebotomy treatments aren’t helping me anymore, and I’m now basically waiting around to clot up and die. I’m a 47 year old man. I believe that all diseases can be cured naturally. I’m just not sure if anyone was ever cured of this rare blood cancer using Fenbendazole. Any advice would be greatly appreciated. Thank you for reading my post. God Bless You!

          1. fenbendazole

            Hello Carmine,
            We empathize with your situation. Polycythemia vera (PV) is a serious and complex condition that necessitates careful management. While Fenbendazole has shown effectiveness in treating various types of cancer, its impact on your specific case is uncertain. The outcome depends on multiple factors, including the stage of your disease, the cancer’s response to treatment, your immune system, and overall well-being.
            Certain natural supplements and therapies can aid in managing symptoms and improving general health, but they should be used alongside, not in place of, medical treatment. For instance, some patients incorporate dietary changes, stress management, and other lifestyle adjustments as part of their care plan.
            If phlebotomy is no longer providing the desired results, other treatments for PV, such as low-dose aspirin, medications that reduce blood cell production (like hydroxyurea or ruxolitinib), or newer therapies currently under study, are available. It is crucial to discuss all potential options with a hematologist who specializes in blood cancers.
            A holistic approach that integrates conventional treatment with supportive therapies such as nutrition, physical activity, and stress reduction may help improve your quality of life while managing your condition.

  171. C.A.

    Hi there… Thanks so much for the site! I have been on a CDS protocol (chlorine dioxide) for the last month waiting for my fenben to arrive. I have a stage 0 diagnosis of breast cancer. With my 115lbs I am now taking 222mg of fenben with a break on the sixth day. Are you able to comment as to whether fenben can be taken with CDS and also ivermectin?

    1. fenbendazole

      Hello,
      Thank you for your question. We specialize in providing information about Fenbendazole, and there is limited scientific data on combining it with CDS and Ivermectin. However, here are some important precautions to ensure your safety:
      Be vigilant for any new symptoms or side effects such as gastrointestinal discomfort, liver enzyme changes, or allergic reactions. Keeping a health log can be beneficial.
      Regular blood tests are crucial to monitor liver and kidney function, helping to detect early signs of toxicity.
      Be aware of potential cumulative toxicities from these treatments. Introduce Fenbendazole gradually if you are already using Ivermectin and CDS to identify any specific side effects.
      Consider supportive supplements, like milk thistle, for liver protection.
      Finally, be aware of signs of allergic reactions such as rash, itching, swelling, severe dizziness, or trouble breathing, and seek immediate medical attention if needed.
      While there are no well-documented interactions between Fenbendazole, CDS, and Ivermectin, combining these treatments requires caution and close monitoring. If you have been taking Ivermectin and CDS without side effects, adding Fenbendazole should not be problematic, but attentiveness to your body’s responses is essential.
      Wishing you the best on your health journey.

    Hi – I have read the above protocols and an keen to start using Fenbendazole … I have Non Hodgkins Lymphoma .. and have had 6 months of chemo (monthly for 2 days – 12 days total.

    My question is : Should Ivermectin be used along with the Tipps protocol ? There is no mention of Ivermectin and from what Ive read it has similar anti cancer properties and some people use both

    Thank you

    1. fenbendazole

      Hello Robert,
      Joe Tipp’s primary protocol drug is Fenbendazole. We specialize in providing information about Fenbendazole and unfortunately do not have additional details regarding the use of Ivermectin in humans.
      We hold back from recommending ivermectin because it is a more sensitive substance, and people’s reactions to it can be highly variable. This variability makes it significantly more challenging to provide accurate advice and ensure the safety of those using it. Managing the diverse responses to ivermectin requires careful monitoring and individualized medical oversight, which is difficult to achieve in a general advisory context. Our goal is to prioritize the safety and well-being of our readers, which is why we focus on substances with more predictable outcomes.
      We apologize for any inconvenience and appreciate your understanding.
      Regarding the use of Fenbendazole, it is crucial to regularly check blood tests and monitor your overall well-being, particularly when the drug is combined with other off-label medications. Regular monitoring helps ensure safety and detect any potential side effects early, allowing for timely adjustments to your treatment plan.

        32 lb corgi fighting oral osteosarcoma!!
        What’s the dose please?

        1. fenbendazole

          Hello, Stacy!
          Thank you for the question. 32 lb dog should use 222mg of fenbendazole. Give fenbendazole once a day for four days in a row. Then, for the next three days, do not give your pet fenbendazole. Repeat this cycle every week.It may take 3-6 weeks for the therapy to begin working in some circumstances.Mix the daily dosage with a modest portion of the usual food. To ensure that the fats on the food are properly absorbing the food, let the meal and fenbendazole mixture sit for 5 minutes. Fenbendazole should not be given to pups under the age of 6 weeks.

  173. Ted

  174. Veronika

    Hi there,
    My cousin’s son who recently turned one was just diagnosed with brain cancer. Tumors all over, they can’t be all removed, chemo is not an option. Is there any way he could be put on fenbendazole (by splitting tablet in half let say) or is he simply out of luck since he is too little and doesn’t weigh enough…

    1. fenbendazole

      Dear Veronica,
      We regret to inform you that, due to potential risks and the lack of comprehensive safety data, we generally do not recommend fenbendazole for children of this age. The child’s reaction to this treatment is uncertain and could be unsafe due to possible side effects.
      However, the decision ultimately rests with the parents, and we cannot forbid them from administering fenbendazole to their child. We understand that parents sometimes face very difficult decisions regarding their child’s treatment, especially when standard methods are ineffective.

  175. Ted

    My 8 year old mixed breed dog has several Lipoma type tumors, these are “fatty” soft to touch, and supposedly noncancerous. I have never had these tested. Is there a suggested Fenbendazole protocol effective for these type tumors? Or a just to be safe type protocol in case there is unseen cancer? My dog shows no signs of hurting. I ran the Dosage Calculator and its set up only as if a pet has cancer now. What if I want to give Fenbendazole as a preventative, and for how long? Thank You.

    1. fenbendazole

      Hello Ted,
      There is currently no significant evidence or clinical trials showing that fenbendazole is effective in treating lipomas or lipoma-like benign tumors. Fenbendazole is used to treat all types of cancer because it can disrupt microtubules in cancer cells. However, lipomas are composed of fat cells and are typically removed surgically or through liposuction.
      If you are considering giving your dog fenbendazole as a cancer preventative, use the following schedule:
      Administer 1 capsule of the appropriate dose based on your dog’s body weight three times a week, once a day after a fatty meal. Then, do not give fenbendazole for the next four days. Repeat this cycle weekly.
      If you have any further questions, we are happy to help.

  176. Iliana

    Fui diagnosticada con CA de mama. Tuve cirugía. No hice quimio ni radio. Un año después vino metástasis a columna sin perjudicar aun la medula. Debí aceptar la inmunoterapia que es Letrozol y Palvociclib (rRampra) y Denosumab, con efectos secundarios muy delicados.
    Solo he encontrado el Fenbendazol en líquido, en concentración: cada ml contiene 100 mg de fenbendazol. Yo deberia tomar segun mi peso 222 mg de cápsulas.
    Pero tambien lei que para
    NEOPLASIAS ACTIVAS MALIGNAS que es mi caso, el protocolo indica 444 mg de capsulas al dia, con un dia descanso.
    CUANTO SERIA ESO EN LIQUIDO? Creo que dos centímetros de jeringa ml/cc – Si?
    Y en este caso el liquido se toma mezclado en agua o directamente sin mezclar con nada?
    Muchas gracias.

    1. fenbendazole

      Dear Iliana,
      Based on the information you provided, you need to calculate the correct dose of liquid fenbendazole according to its concentration. You will need 4.44 ml of liquid fenbendazole to achieve the required dose of 444 mg.
      Since a 2 ml syringe will not be sufficient for this dosage, you will need a syringe that can hold at least 5 ml to ensure accurate dosing.
      For administration, it is generally safe to mix liquid fenbendazole with water to make it easier to swallow. You can also mix it with a small amount of food if that improves the taste.
      If you prefer to take it directly without mixing, make sure to drink plenty of water to help it go down smoothly.
      Additionally, monitor your health regularly and get the necessary blood tests to ensure the treatment is proceeding safely and effectively.

  177. Carolyn

    Can this protocol be used for a person with pancreatic cancer, & if so, are there any extra precautions to be aware of?

    1. fenbendazole

      Hello Carolyn,
      Fenbendazole is generally considered safe and well-tolerated. When used according to the dosage and schedule recommended by a dosage calculator, side effects in humans are very rare. However, like any medication or supplement, it can cause short-term side effects such as liver toxicity, gastrointestinal issues, or allergic reactions. Therefore, it is advised to continuously monitor your overall health, regularly perform blood tests, and check liver enzymes while using fenbendazole, especially if it is taken alongside other drugs metabolized by the liver. This approach helps ensure the safe use of the medication and minimizes the risk of adverse side effects.

  178. Nameera

    Hi there,

    For curcumin dosage: it says “Bio-Available Curcumin 600 mg. Take 1 capsule two times a day after breakfast and lunch with no pauses.”

    1) Does that mean 600 + 600 mg= 1200 mg / day?

    2) If I’m having hard time finding 600 mg tablets, would 500 mg tablet suffice, or would it be insufficient?

    Look forward to your reply, thanks!
    Nameera

    1. fenbendazole

      Dear Nameera,
      Thanks for the great question.
      To address your first question, it is recommended to take bio-curcumin at a dosage of 600 mg twice a day, totaling 1200 mg per day.
      For your second question, if 600 mg capsules are unavailable, you can take the 500 mg capsules twice a day. This slight deviation from the standard dose is acceptable and should still be effective.
      If you have any further questions, please feel free to contact us. We are here to help and will do our best to answer all your queries.

        1. Cody Stewart

          What is the appropriate dosage of ivermectin to combine with fenbendazole in a 180lb dog with an aggressive cancer?

          1. Fenbendazole.org

            Hello Cody,
            For a dog weighing 180 lb (approximately 81.6 kg), the commonly used cancer-supportive dosage of fenbendazole is 888 mg once daily for four consecutive days, followed by three days off, repeating this cycle weekly. As for ivermectin, we do not provide official dosing recommendations, as our focus is on fenbendazole information. However, the most commonly referenced dosage in off-label protocols is approximately 0.2 mg per kilogram of body weight, but this should be confirmed with a veterinary professional, especially for dogs, as breed sensitivity and individual health factors must be considered.

  179. Nicole

    Hi! Thanks for all the great info! I’m looking to desparasite myself. I’ve tried Reese’s pinworm medicine and it helped a little but threw off my digestion for a couple weeks so I’m nervous for the 5 day protocol. Does it affect digestion a lot? Also, is there any other support recommended? I have bentonite I’m planning to take internally as a binder. How long after a dose should I wait to take bentonite? I’ve heard it’s good to do a parasite cleanse during a full moon as they’re more active but I’m getting desperate and don’t want to wait 3 weeks. Will it make a difference the time of month I do it? I don’t know what type(s) of parasites I have but have struggled with chronic bloating and fatigue for years but it seems like fenbendazole is pretty broad spectrum. Does my whole family have to do it too? No one else has symptoms? Thanks so much for any help!

    1. fenbendazole

      Dear Nicole,
      Fenbendazole is generally well-tolerated and does not significantly affect digestion in most people. However, individual reactions can vary. If you have had digestive problems with medications in the past, consider starting with a lower dose to see how your body responds.
      To avoid interactions and ensure maximum effectiveness when taking bentonite clay, take it at least 1-2 hours before or after fenbendazole. This separation prevents the clay from absorbing the medication, ensuring both substances work effectively.
      Regarding parasite activity and the moon phase, the belief that parasites are more active during a full moon is based on anecdotal evidence and some natural health practices. Although some people think this timing increases the effectiveness of a cleanse, there is no solid scientific evidence to support this. If you are experiencing significant discomfort, you do not need to wait for the full moon to start your cleanse. Starting earlier is unlikely to negatively impact the results.
      If you suspect a parasitic infection and experience symptoms like chronic bloating and fatigue, it might be beneficial for your entire family to be evaluated and treated simultaneously. Parasites can easily spread among family members, and treating everyone at the same time can help prevent reinfection.
      It is crucial to monitor your symptoms and overall well-being. Regular blood tests can help track your body’s response to fenbendazole and other treatments. By following these recommendations and keeping a close watch on your health, you can manage your treatment more effectively and minimize any negative effects.

  180. Laura

    Would your parasite protocol for humans be used for pinworms?

    1. fenbendazole

      Dear Laura,
      Thank you for the excellent question.
      Pinworms (Enterobius vermicularis) are a type of nematode. Fenbendazole is effective against various nematodes and may be beneficial in treating pinworms. You are likely to achieve positive results in eliminating these parasites from your body with fenbendazole.

  181. Jeff

    Hi there, I appreciate all the information on Fenbendazole as a possible treatment for cancer. Thanks and please continue. My question is related to Joe Tipp’s protocols on your Dosage page. Are Berberine, Quercetin and Vit E not a part of those protocols anymore? I thought I saw them listed elsewhere, reason I ask. Much thanks in advance.

    1. fenbendazole

      Dear Jeff, thanks for the great question.
      Joe Tipps’ protocol focuses primarily on the use of fenbendazole in the treatment of cancer. The main components of the protocol are:
      1. Fenbendazole: usually 222 mg daily with food.
      2. Curcumin: 600 mg daily.
      3. CBD oil: 25 mg daily.
      4. Vitamin E: 400-800 IU daily.
      The original protocol does not explicitly mention berberine or quercetin as key components. However, some variations or additional recommendations may include other supplements for potential health benefits.
      Vitamin E is included in the original protocol and is recommended for its antioxidant properties, which can help protect cells from damage.
      The primary role in cancer treatment within protocol is carried out by fenbendazole. While other supplements may be included in the treatment protocol, they are not essential.

  183. Lindsey

    My car was diagnosed with what might be bladder cancer. I joined a lot of Facebook groups asking for the dosage. I was told low doses are always the best to not harm the liver and that 7.5mg per pound daily is efficient to treat cancer as an overload isn’t needed.
    Is this true??
    My cat had perfect bloodwork he is 20ish lbs and only has the big mass next to his bladder and urinating blood.
    I have the 1gram 222mg packets from Amazon.
    I gave him a half a packet this morning with his raw food and some fish oils which amounts to 111mg and a 1/4tsp of salmon/pollock oil.

    I’m waiting on pet wellbeing’s mushrooms and life gold supplements as well as vitality sciences celloquent gold and vital lipids (which will take place of the fish oil).

    When I do receive the supplements, how much should I space them out when giving the fenbendazole? Should I give the fenben in the morning or night? Should I be giving with the fish oil?? And should I space out the supplements through the day as well?

    I am lost I just want my baby to be better!
    Thank you!!

    1. fenbendazole

      Hello Lindsey,
      Please utilize our dose calculator to determine the optimal dosage for your pet. You can access the calculator here:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      For a cat weighing approximately 20lbs, the recommended daily dose of fenbendazole is 444mg. Administer this dose once a day for four consecutive days, followed by a three-day break without fenbendazole. Continue this weekly cycle.
      It is advisable to give fenbendazole in the first half of the day, and you can enhance its absorption by combining it with oil. There is no need to space out fenbendazole from other supplements, as it is generally safe and compatible with them.
      However, given your cat’s cancer diagnosis, it is important to monitor her overall health closely and conduct regular blood tests to ensure her well-being throughout the treatment.

  184. Nameera

    Hi,
    Is a Ketogenic diet recommended with Fenbendazole treatment, or not?
    Look forward to your reply!

    1. fenbendazole

      Hello Nameera,
      Fenbendazole does not necessitate a special diet, so you are free to follow a ketogenic diet if you choose; it will not impact the absorption of fenbendazole. It is important to take it with or after a meal, as the presence of food in the gut can enhance its bioavailability. Any food consumption slows down intestinal activity and boosts blood flow to the digestive tract, thereby improving the drug’s absorption.

  185. Meri

    Hello again,

    Thank you for your quick and thorough response. Just one more question. The product that I purchased for my husband, Merck Safe-guard suspension for goats (10% 100mg/ml), I am hearing from some should not be used for hormone driven cancers due to a filler in that particular formulary that can cause additional issues with those types of cancer. Do you have any information on that and if that’s the case, is there a better option for prostate cancer?

    Thanks so much again,
    Meri

    1. fenbendazole

      Dear Meri,
      Thank you for your question. The concern that the additives in Merck Safe-Guard Suspension for goats could exacerbate hormone-driven cancers is reasonable, as veterinary formulations often include ingredients not assessed for human use, especially in conditions sensitive to hormonal changes like hormone-responsive cancers. To avoid potential risks associated with these additives, we suggest opting for pure Fenbendazole without any excipients. You can find a list of reputable suppliers here: https://www.fenbendazole.org/suppliers/

  186. Meri

    Good evening,

    My husband has been on Lupron injections every three months for the last 11 months for stage 4 metastatic prostate cancer. His PSA is beginning to go up (Jan 0.01, March 1.0, May 2.0).

    I have purchased Merck Safe Guard fenbendazole for him, but I wanted to check first as he is also a type 2 diabetic using metformin, Glipizide, and Mounjaro. Is is safe for him to take those and fenbendazole adjunctively?

    Also, he has a nuclear bone scan coming up in two weeks. I know we have to hold his soursop tea for a couple of days because it can interfere with the tracer and the results. If he begins fenbendazole, is there any known directive that requires holding that as well?

    Thank you,
    Meri

    1. fenbendazole

      Dear Meri,
      To address your first question, yes, fenbendazole is generally considered a safe medication, and there are no documented adverse interactions between fenbendazole, glipizide, metformin, and Mounjaro. However, it’s important to note that any medication can cause side effects, particularly with prolonged use or at high dosages. Therefore, we recommend regular monitoring of your husband’s health and routine blood tests to ensure his well-being.
      Regarding your second question, although there is no direct evidence to suggest that fenbendazole interferes with nuclear bone scans, the absence of specific data concerning its interaction with diagnostic procedures calls for a cautious approach. Therefore, we recommend discontinuing fenbendazole two days before and two days after the scan to avoid any potential issues.

    Hello! I believe I have accumulated many parasites over my 20 years of life, so I’ve decided to get rid of them now. I bought a couple of tablets with fenbendazole in my city, but these tablets also include Pyrantel pamoate and Praziquantel. Each tablet contains 60 mg of fenbendazole, 56 mg of Pyrantel pamoate, and 20 mg of praziquantel. I couldn’t find the dosage for the last two drugs for humans. Now I don’t know if it will be dangerous to take these tablets.

    1. fenbendazole

      Dear Andrey,
      Pyrantel pamoate and praziquantel are antiparasitic drugs commonly used to treat a variety of parasitic infections in humans. These drugs are generally considered safe when used as directed, but like all medications, they can have side effects and risks.
      Unfortunately, we do not have information on the dosages for these drugs.
      If you decide to use pure Fenbendazole for deworming, we suggest you take a look at our list of reliable Fenbendazole suppliers.
      You can find the list here: https://www.fenbendazole.org/suppliers/

    My young teen 14-yo 160lbs 5’10″having intermittent neurological problem same like Multiple Sclerosis (MS) symptom maybe cause by Toxoplasma Godin variant, can Fendenbazole kill or eradicate the Toxoplasma Godin or the symptom? If so, what other stuffs I can give with Fendenbazole 200mg capsule per day.

    If not, what else to do instead of Fendenbazole?

    1. fenbendazole

      Hello Jay,
      Fenbendazole is an antiparasitic drug that’s commonly used to treat parasitic worms in animals. However, it is not typically used for treating infections caused by protozoa like Toxoplasma gondii, which is the parasite responsible for toxoplasmosis.
      Toxoplasmosis is usually treated with a combination of drugs such as pyrimethamine and sulfadiazine, along with folinic acid to prevent side effects from pyrimethamine. These medications specifically target the protozoal infection and are the standard treatment for managing toxoplasmosis, especially in severe cases or in individuals with weakened immune systems.
      It is important to consult with healthcare providers for appropriate diagnosis and treatment options for toxoplasmosis or any related symptoms. They can provide guidance based on the latest medical evidence and the individual’s health needs.

    Hi! I want to use mebendazole to affect a desmoid tumor, but I do not know what dosage to use and for how many days. I want to conduct an experiment before CT in conjunction with fasting. Please help me choose the dosage

    1. fenbendazole

      Hello Ann,
      We are a Fenbendazole informative page, and here you can access a dosage calculator specifically for Fenbendazole. Unfortunately, we do not have specific dosage information for Mebendazole as our resources are dedicated to Fenbendazole.
      However, all benzimidazoles, including Fenbendazole, Mebendazole, and Albendazole, share a similar structure and mechanism of action. Therefore, the dosage and frequency of their use are likely to be quite similar.

  191. Michelle Bliss

    Hi David,
    So I am a little confused between this page and dosing for parasite cleansing and information given on the page, “Fenbendazole for Human Parasites” which reads,
    Fenbendazole protocol to kill parasites
    Fenbendazole is commonly employed as an antiparasitic treatment. The typical dosage recommendation is 1 gram for every 10 lbs of body weight, administered consecutively for three days…”
    So, for my 230lb husband, that would be a single dose 23 grams of Fendendazole each treatment day, 14 grams for myself, 9 grams for my older son, and 6 grams for our younger son?
    The calculator on this page is only showing 1 gram for the younger ones whose weight is under 100lbs, and then 2 grams for the adults over 100 and 200lbs. So, I am a bit confused. We are working at cleaning out parasite infections. Thank you so much for any clarification you are able to give.

    1. fenbendazole

      Hi Michelle,
      Thank you for your question. Our dosage calculator is designed to ensure maximum treatment efficacy without causing harm to the human body. Fenbendazole has a half-life of about 24 hours, and the optimal dosage, which ranges between 222mg and 444mg per day depending on body weight, is specifically calibrated for optimal absorption. Therefore, there is no advantage in taking a higher dose. We recommend that you use our dosage calculator and adhere to the provided consumption guidelines.

  192. Christina

    My husband bought panacur in paste form. What amount is 1 dose?

  193. Alexandra

    Hi
    Thank you for this page.
    My dog (Belgian shepherd) is 14 and in very good shape. But as her blood analysis showed a tired liver she undergone an echography and she was diagnosed with a large 6cm tumor located between the liver and the pancreas.
    It’s hard to determine where the cancer started but the liver is plenty of nodules (metastasis) some of the more than 1 cm.
    I read that fenbendazole has an effect on liver so I was wondering whether it would be a bad idea to use it, maybe, has the liver is already in bad shape.
    What do you think ?

    1. fenbendazole

      Hello, Alexandra. Thank you for a question!
      Any potential benefits of using fenbendazole for cancer treatment should be carefully weighed against the risks, especially in a dog with significant liver impairment. The liver’s ability to process medications could be compromised, which might lead to increased toxicity or adverse effects. However, fenbendazole’s toxicity is low, so it may be beneficial. We are unable to provide guidance on how to proceed in regards to a 100% certainty. Nonetheless, we advise you to attempt fenbendazole treatment while monitoring the liver enzyme levels of your Shepherd every month or two. Additionally, it would be wise to promote the liver health of your dog through diet and, if your veterinarian recommends it, supplements.

  194. Dale Valiukas

    I just ordered Paragon. It says to take it 3x a day with food and for 20 days. It’s a mix of fembendazole and ivermectin 12mg. I’m kinda nervous to start taking it.

    1. fenbendazole

      Hello, Dale. Thank you for a question.
      It would be difficult to counsel regarding this case. Initially, the quantity of fenbendazole present in this compound was not specified. Second, the half-life of fenbendazole in the human body can vary from a few hours to twenty-four hours; therefore, once daily dosing is recommended. Should not be a problem if taken twice daily, but three times daily may be excessive in the long run due to the fact that it will accumulate in the organism and may have adverse effects on the liver.
      We recommend taking the two supplements you mentioned individually and adhering to the fenbendazole dosage protocol outlined in the fenbendazole dosage section of this page.

  195. Graeme Boucaut

    Can you take Fenbendazole with Metformin HCI.

    1. fenbendazole

      Hello, Graeme.
      While both fenbendazole and metformin are generally well-tolerated, it can cause side effects such as gastrointestinal upset, diarrhea, and abdominal discomfort and liver damage. To monitor liver health, it is advisable to undergo liver enzyme blood tests every one to two months. Additionally, monitor your overall wellbeing and health. If there are significant deviations from your usual routine, it is advisable to seek the advice of a healthcare professional. Additionally, remember to take milk thistle and other digestive health supplements. Their quantities and descriptions can be found in the fenbendazole guide section.

  196. Doug

    What might be a good Fenben protocol for prophylaxis?

    70 year old male in good health but probably some prostate issues. Does not want to enter into the medical maw of allopathic procedures and “solutions.” Realizes that some sort of cancer is more likely every year at this age.

    Thank you.

    1. fenbendazole

      Hello, Doug. Thank you for a question.
      There is an option in our fenbendazole dosage calculator to select “cancer prevention protocol”. The dosage is smaller and the intervals of usage are modified.

      1. Doug

        Are there any studies, presentations on Fenbendazole as a treatment for BPH? Thanks.

        1. fenbendazole

          Hello, Doug, thank you for a question.
          Since benign prostatic hyperplasia is a non-cancerous enlargement, it is harder to tell how fenbendazole would affect it (if at all). We could not find any stronger evidence or professional studies on it.

    This site is brilliant ,AMEN.

  198. Anbe

    I have Panacur C for dogs. Is this safe for humans?

    1. fenbendazole

      Hello, Anbe.
      In general, it is thought to be rather safe for humans. However, adverse effects may occur. The most prevalent adverse effect is gastrointestinal disturbance (e.g. vomiting or diarrhea). Additionally, fenbendazole may have an effect on the liver. If you don’t overdo it and take breaks during the treatment, the side effects should be low or non-existent. Also, we always recommend tracking your liver enzyme levels by blood test.

  199. David

    HI! A couple questions:
    1) I’ve heard that taking vitamin E with Fenben makes it more effective, is that true? Is Fenben ineffective without E?
    2) My mom is taking Fenben 444mg once a daily(due to her weight class). I see some people with results took it twice a day, does that make it more efficient or effective and quicker to show results?

    Thanks so much for your help:0)

    1. fenbendazole

      Hello David,
      Thank you for your question.
      Several studies suggest that Vitamin E can enhance the effectiveness of Fenbendazole, though these studies were limited and inconclusive. If you choose to take Vitamin E, remember that it has blood-thinning properties. Therefore, we recommend monitoring your health closely and undergoing regular blood tests.
      Fenbendazole is recommended to be used once a day and in a dose not exceeding 444 mg. To ensure that you have selected the correct dosage and frequency for your mother, please use our dose calculator:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Fenbendazole has a half-life of approximately 24 hours, which means taking it more than once a day does not enhance its effectiveness. Instead, it accumulates in your body and may place additional strain on your liver.

  200. Lori

    Hi, my mom was diagnosed with stage 4 bile duct cancer, has this been used before? Should we get capsule or powder? I saw several mention Curcumin and Milk Thistle, could you explain what that’s for?

    1. fenbendazole

      Hello Lori! Thank you for a question.
      Curcumin and milk thistle, through their antioxidant and anti-inflammatory properties, may help protect the liver. Their ability to reduce oxidative stress and inflammation can support liver function and mitigate potential adverse effects associated with fenbendazole treatment.

  201. Vievee

    Hi!

    Unfortunately our dog has been diagnosed with an aggressive cancer.
    Should we:
    1) He is currently 104 pds. We are giving him daily 666mg. Should we increase the amount, if so to how mg?
    2) Should we continue to give the fenben 7 days/week or 3 days on/4 days off or 4 days on/3 days off?

    1. fenbendazole

      Hello Vievee and thank you for your question.
      Do not increase the dose. It is high enough already. You should also give your dog a few days to rest from fenbendazole for his liver to recover. Additionally, you may wish to seek the assistance of a professional veterinarian and purchase dog-specific supplements to treat his liver enzymes.

      1. Diana

        In Nov. 2021 werd bij mij dikke darm kanker ontdekt met uitzaaiingen naar de lever. Eerst werd de tumor in de dikke darm weggehaald en in febr. 2022 de operatie aan de lever. In nov. 2022 weer een operatie aan de lever vanwege nieuwe uitzaaiingen.
        Helaas waren de uitzaaiingen in maart 2023 weer terug en werd i.p.v. een operatie nu gestart met een zware chemokuur van 8 stuks. In september bleek dat deze goed was aangeslagen en werd ik alsnog in okt 2023 een keer geopereerd om de resterende uitzaaiingen weg te halen. We hoopten dat ze nu weg zouden blijven. Het was dan ook een grote tegenslag toen ik in februari 2024 vaginaal bloedverlies kreeg en op de scan het volgende uitkwam; een grote tumor op mijn eierstok, een kleinere op het buikvlies en een paar kleine plekjes op mijn longen. Ben nu in april weer aan mijn 2e van de voorlopig 4 chemokuren bezig, met de opzet om het zo lang en zo goed mogelijk vol te houden.
        Nu lees ik van dit middel en heb het meteen in huis gehaald. Kunnen jullie me advies geven, hoe ik dit het beste kan gebruiken? Met of zonder pauze? En kan ik dit gewoon tijdens de chemo gebruiken?
        Alvast heel hartelijk bedankt!!

        1. fenbendazole

          Hello, Diana.
          In the FENBENDAZOLE DOSAGE GUIDE section, a great deal of information regarding the use of fenbendazole and other supplements is provided. It is worth noting that fenbendazole treatment should be discontinued during cycles of chemotherapy. 2 days before and 2 days after chemotherapy. You should proceed only after this period has passing. This is because chemotherapy is most effective against rapidly proliferating cells (cancer cells, hair, nails, epidermis, etc.). Cancer proliferation is slowed by fenben use; consequently, chemotherapy may be less efficacious. Therefore, you should maximize the benefits of each therapy you employ.

  202. Robert S

    My dad has stage 3 kidney disease and just got diagnosed with bladder cancer, can he do these protocols?

    1. fenbendazole

      Hello, Robert. Thank you for contacting.
      Yes, your father may do these protocols. Also you may consider traditional treatment and consult medical health professionals. Fenbendazole can be great help with chemo or radiation altogether. Only then you should pause on protocol few days prior chemo/radio round, and continue protocol 2 days after the traditional treatment. This is because fenbendazole slows cell proliferation of cancer, but traditional treatment targets fast proliferating cells the most.

      1. Marlee Quintasket

        Hi there,
        I have started this protocol for my young hen (sadly only 9 months old) with a cancerous tumor in her abdomen.
        I have inquiries about our dosage schedule. Is the Fenben, Curcumin and CBD to be given consecutively within the same dosage period/hour or is there a time frame you advise they be given individually ?
        I am also wondering if this is supposed to be done for a span of weeks/months — no breaks? Or what do you advise?

        1. fenbendazole

          Hello Marlee,
          Give 25mg of fenbendazole once a day for four days in a row. Then, for the next three days, do not give your pet fenbendazole. Repeat this cycle every week.
          Febendazole should be taken with or after food. Give fenbendazole once a day for four days in a row. Then, for the next three days, do not give your pet fenbendazole. Repeat this cycle every week.
          Consult your pet’s veterinarian about supplement use.

  203. graciela umpierre

    Hello. My husband just had a colonoscopy and it looks like he has cancer in the rectal area which spread to the lung and liver. I saw in one of the comments that fenbendazole causes stress to the liver. Should he take it? if so should he do the aggressive treatment or the first one listed? I have taken it as prevention, and recommended this site to my friends. thanks

    1. fenbendazole

      Dear Graciela,
      You can determine the appropriate dosage and schedule for Fenbendazole using our dosage calculator, which will help ensure a safe dose for your husband:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      We recommend regularly monitoring his general well-being and conducting liver enzyme tests. If your husband will feel good after a few weeks of using the recommended dose, you may consider carefully increasing the dose. Please note that the maximum recommended daily dose is 444mg.

  204. Nicola

    Hi, I am wanting to take this for parasites. However my most recent blood work has shown a high level of ALT. I am healthy, other than a rheumatoid arthritis diagnosis. Should I be ok starting this while those levels are already high?
    Thanks

    1. fenbendazole

      Hello, Nicola, thank you for a question.
      You may first fix your ALT levels to normal. Milk thistle may really help with that. Due to the fact that fenbendazole is known to cause some liver stress, it is far more prudent to address liver enzymes first.

  205. Max

    Hello,
    My dog is 104 lbs. According to the calculator his dosage for cancer treatment would be 666mg/day.
    If I am using the Panacur granules (box says 22.2% (222mg/g) ) does this mean that would be 3 Grams of Panacur granules/day? Is this correct? Just wanted to be sure I did the calculation correctly.
    Thank You!

    1. fenbendazole

      Hello, Max!
      Your calculation is correct. Also do not forget to follow the supplement program like milk thistle, because 666mg is somewhat high dose. Also take a blood test for liver enzymes at least every 3 months to monitor your liver health. Best regards!

      1. Max

        Thank you for the quick response!
        Our vet said our dog has an aggressive cancer.
        Should we:
        1) increase the dosage to something more than 666mg?
        2) Give the fenben 7 days/week or 3 days on/4 days off or 4 days on/3 days off?
        Thanks again!!!!

        1. fenbendazole

          Hello Max, thank you for asking.
          Do not increase the dose. It is high enough already. You should also give your dog a few days to rest from fenbendazole for his liver to recover. Additionally, you may wish to seek the assistance of a professional veterinarian and purchase dog-specific supplements to treat his liver enzymes.

  206. Dennis Rodgers

    Hello, I have esophageal cancer and haven’t been able to swallow anything for over 16 months.
    I have a feeding tube that I use for liquid nourishment and I need to figure out a way of getting this Fenben into my system.
    What do you suggest to use as a liquid transport for Fenben and my feeding tube?

    1. fenbendazole

      Hello, Dennis. Thank you for a question.
      Fenbendazole is more soluble in fat or oil-based liquids compared to water. Mixing fenbendazole with a fatty substance, such as olive oil, coconut oil, or peanut butter, can help improve its solubility and absorption in the body. In your case, powder would be a better choice than tablets. If you have capsules, simply take the powder out of them. You may also utilize paste or liquid form.

  207. Wynetta Vick

    I recently heard about fenbendazole for cancer treatment. I have cancer and want to know if what I am planning to take is correct. Plan to take 222mg of fenbendazole every day 7 days a week but could rest one day a week. Bio available curcumin 600mg twice a day, and 250mg of milk thistle to protect my liver.
    what else do I really need to take for this protocol. Thank you.

    1. fenbendazole

      Hi, Wynetta. Thank you for questioning.
      Everything you described is excellent! Melatonin can also help you sleep and recover better. CBD oil may offer the same beneficial effects for relaxation and rehabilitation. We do advocate pausing your routine for a few days each week to allow your liver to process and relax from the treatment.
      Remember that you may want to monitor your liver enzyme levels with blood tests.

  208. Ro

    What would the dosage be if you have TNBC with mets to the liver? What about the combination of Ivermectin and Fenben?

    1. fenbendazole

      Hello, Ro. Thank you for asking.
      The protocol for TNBC is the same as described in the dosing guidance section. You may also calculate the dose there. https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      In terms of Ivermectin, we will refrain from discussing dose and synergy with other supplements because our goal here is to assist people get familiar with fenbendazole and its application.

      1. Kat

        Help me understand. The protocol is 222mg per 3 or 6 days no matter your weight. 1pkg of 3 panacur C for a 10lb dog is equivalent to 1g which is 1000mg 222mg and 1 pkg of panacur C for a 40lb dog is 4g, equivalent to 4000mg. Each box says that there is 222mg fenben per single pack – that alone doesn’t make sense. If the protocol is 222mg per day, then 1 single yellow pack for a 10lb dog is the correct dosage? One dr who did a parasite cleanse said that she took 222mg but that she multimedia it to her body weight of 150lbs. If I take it to the logical conclusion, then it requires 15 X 222mg pks of the 10lb dog or 4pks of the 40lb dog dosage. Which is it?

        1. fenbendazole

          Hello, Kat and thank you for a comment.
          Ope Panacur C 1000mg packet has 222mg of fenbendazole, so if Your dog needs Pabacur C 4000mg would have 888mg of fenbendazole. For your dog 222mg is enough.

  209. Virgulino

    Hello,

    Thank you for your work.
    I wonder if you have any thoughts regarding combination of the fenbendazole protocol (6 days on / 1 day off) with high-dose (up to 100 grams) IV vitamin C twice a week as a potent cancer treatment.
    Also, would Ivermectin be a good companion to the fenbendazole protocol? If so, any thoughts on dosage?
    Thanks again.

    1. fenbendazole

      Hello Virgulino! Thank you for this question.
      Theoretically, combining these approaches could have complementary effects on cancer cells.Some preclinical studies have suggested potential synergy between fenbendazole and vitamin C in inhibiting cancer cell growth. However, more research is needed to understand the mechanisms underlying any potential synergistic effects. Also cancer treatment is highly individualized, and what works for one person may not be effective or safe for another. It’s crucial to consider factors such as the type and stage of cancer, overall health, and treatment goals when exploring combination therapies.

  210. Leigh Ann

    I’ve already purchased the liquid Safeguard and would like to use this for me as a preventative. I weight 134lbs. According to the dosage I would take 222mg. Is that 22.2 ml in liquid form? Thank you in advance!!

  211. Michelle

    Hi
    What if the pacient has both of his kidneys removed and is on dialysis?
    Is the 222mg per day treatment suitable for this person or a different dose is required?

    1. fenbendazole

      Hello, dear Michelle. Thank you for a question!
      Fenbendazole utilization should be restricted to a maximum of 50 mg with sustenance during hemodialysis or be avoided entirely in such circumstances. This response is attributed to the fact that doses are typically decreased by a factor of 5-6 in cases of renal injury, or the medication is discontinued entirely.

  212. Svetlin Petkov Matthew

    My dog ​​is 50 kg.
    I have Panacur 10% (1 liter)
    According to the protocol here, I see that his dose for parasites is 2500 mg and for cancer is 666 mg of fenbendazole.
    How much would this be in ml. if fenbendazole is 10% in 1 liter?

    1. fenbendazole

      Dear Svetlin, thank you for your question. It is easier to count and administer dosage in pure fenbendacole capsules and/or powder, so that would be an easy option. We also want to take notice, that not only dosage, but also all the protocol of use changes if you want to fight cancer or parasites. Parasites should be attacked with a big strong dose, but then you should end the use not to damage liver. For cancer, dose is not as big, but cumulative over longer periods of time when using correctly.

  213. Mark Aaron

    Is there any feedback regarding the use of DMSO with fenbendazole?

    1. fenbendazole

      Dear Mark, thank you for a question.
      As of our current knowledge, there is limited scientific evidence on the safety and efficacy of using dimethyl sulfoxide (DMSO) together with fenbendazole by drinking it for any medical condition, including cancer or parasitic infections. Both substances have been studied separately for various purposes, but their combination and ingestion are not well-studied or approved for human use in this manner.

      1. maria

        So you are just using fenbendaxole solely without ivermectin to treat parasites?

  215. Rick

    Rick’s Very Successful 5-Protocol Plan

    After being informed of having a very high PSA # following a physical, I was directed to a Urologist who recommended a biopsy of my prostate. He took 12 samples from my prostate and according to the Gleason scale, 11 of the samples measured 3 out of 5 and one was a 4. So began my quest to regain my health.

    We immediately began studying from the book Healing the Gerson Way: Defeating Cancer & Other Chronic Diseases. We began the vegan diet of organic veggies recommended by the book as well as a regiment of enemas; in my case, I decided on 3/day. My wife followed the vegan diet as it made her health improve significantly.

    We began investigating cancer remedies and about a month into this diet, we came across Fenben and decided to add this protocol to my regiment. I take Fenben 3 days and off for 4 days. Based on my weight (190 lbs.), I take more than the 222mg. that is recommended for my weight but, less than the 444mg. that is recommended for those weighting 200lbs.

    As a third protocol, I also added Curcumin 600mg. twice a day; Quercetin for my immune system 500mg. twice a day; Berberine 500mg. twice a day; and for liver health, a liver detox formula which includes Dandelion 100mg., Milk Thistle 100mg. and Tumeric Root twice a day and 50mg. of Niacin 5-6 times a day (from the Gerson Diet).

    Number 4 protocol is CDB drops under the tongue before sleep and number 5 protocol is exercise and activity based on your age and condition and a positive attitude. I also meditate daily.

      Rick,

      Any updates on your Fenbendazole use that indicate it’s working?

      Thanks

  216. Jennifer

    I’m using fenben for parasite and had a silly question of need to repeat is it 3 weeks from the day started or 3 weeks from when u did the first round

    1. fenbendazole

      Thank you for the question, dear Jennifer! You should repeat 3 weeks from when you did your firs round.

  217. Shelley

    Do I take it for 1 week and then wait 2 weeks and take it again for a full week? Is this the proper dosage?

    1. fenbendazole

      Hello Shelley! Thank you for a question.
      Take Fenbendazole once a day for 5 days in a row. The treatment may have to be repeated one more time in three weeks.
      If unhatched parasite eggs are suspected, repeat the procedure in another round after 3 weeks to make sure the deworming is complete. The second cycle aims to stop re-infection by adult worms that emerge from any eggs that the first treatment did not manage to kill.
      It is recommended that everyone in the house get treated at the same time if more than one person is sick or if the infection keeps coming back with symptoms.
      It may take a lot of time and effort to treat certain parasite infestations. If this is the case, please repeat the deworming procedure after 3 weeks until there is no evidence of parasites and your health has improved.
      Fenbendazole should not be given to children under the age of 2 years or pregnant women. If you still wish to take the treatment, consult your doctor.

    Hello, do you have supplier information to buy CBD oil 25 mg, Take 1-2 drops (total ~25 mg) under the tongue every day before sleep, in the protocol?

    1. fenbendazole

      Hello and thank you for a question!
      CBD oil is primarily utilized to induce sleep, relaxation, tranquility, and positive emotions. There is no need for a specific type of CBD. Even THC is unnecessary in your oil. Thus, as long as you purchase from an authorized, regulated source, everything will be in order. We regrettably cannot recommend any particular source.

    1. fenbendazole

      Dear Tyler, thank you for this question.
      Positive findings have been reported in some studies concerning benzimidazoles (e.g., flubendazole, mebendazole) and myeloma. The pathway of action is recognized to be comparable, which provides justification for anticipating favorable results. Your best bet is to use fenbendazole alongside conventional chemo- and biological therapy regiments to achieve the best outcome.

  221. Cathi

    Hi. I’m so excited by this info. A friend recommended it to me yesterday and I bought all the elements today – arriving by Friday. I have been fighting progressive neuroendocrine carcinoma for 10 years. Lots of different treatment plans but all have either failed or the side effects were too risky to continue the “treatment”. I’m not ready to join my parents and dogs in Heaven but I was told I only have a couple of years. I’m starting the fenbendazole on Friday, 1/12/24. My next MRI is scheduled for 2 weeks later, 1/27/2024. Any possibility that the effects will kick in by then?
    Thank you! My husband has Stage 4 metastasized esophageal cancer. He’s as excited as I am and will also be starting the protocol immediately. We have hope for the first time in YEARS. Thank you! and, Thanks to Joe, too.

    Hi, I’d like to take a course but am interested in residual effects on fertility directly after?

    Not currently pregnant but will be receiving an embryo after the course.

    1. fenbendazole

      Hello and thank you for a question.
      If you are planning on receiving an embryo after the course, there is no need to be worried. Fenbendazole does not have a long half-life and will be out of you system in about 24h. It will not harm your baby if you stop fenbendazole treatment before receiving the embryo.

  223. Lou Brooks

    I have been taking Panacur C (red/orange box) since mid November for low risk PCa, began 3 days a week and now am up to 6 days a week. For my weight your chart says 444mg, which is twice what I now take. This will get expensive and I have looked at FenBen Labs but frankly, I can find no reports of people having success with their product. Anyone here using FenBen Labs FBZ? Also, is it better to take 222mg twice a day or at one time?

    Thanks to all!

  224. Frank

    Also check hydroxychloroquine and Ivermectin as they both have cancer patents and are supposed to be very effective. Doctors won’t subscribe them as it isn’t the set protocol.

  225. Ryan

    Follow up, is there a timeframe where progress should be seen? Thank you for this sight.

    1. fenbendazole

      Hello Ryan,
      The response to fenbendazole can vary significantly among individuals, as it is influenced by several factors. These include age, health condition, weight, dosage, concurrent medications, and the presence of secondary diseases. Therefore, the effects of fenbendazole really depend on these specific individual circumstances. In most cases, it may take between 1 to 4 months for the therapy to start showing results.

    What are the side effects? My wife.started this 3 days ago with stage 4 cancer.

    1. fenbendazole

      Hello Ryan,
      Based on toxicology studies, benzimidazoles like Fenbendazole, Mebendazole, and Albendazole are generally considered safe drugs.
      However, no drug is completely free of side effects. While scientific data does not report significant adverse reactions from taking Fenbendazole, there are anecdotal reports suggesting potential toxicity, you can learn more about it by clicking on this link:

    Hello! Thank you so much for sharing this lifesaving information. I do have a question. Is the CBD oil required? If not, I would rather not take it. If so, is there a reputable source? Many thanks and blessings.

    1. fenbendazole

      Hello Leisha,
      CBD is one of the supplements that we recommend taking along with Fenbendazole: https://www.fenbendazole.org/fenbendazole-information/supplements/
      However, it is not mandatory for you to achieve anti-cancer action.
      Unfortunately, we are a Fenbendazole information page and do not provide people with guidelines on other supplements.

    1. fenbendazole

      Dear Diane,
      Fenbendazole is generally regarded as safe and well-tolerated. Therefore, it is safe to use with the supplements you have listed.
      Additionally, we suggest looking into other supplements that may complement the use of Fenbendazole and potentially enhance its effectiveness. You can find a link to the suppllements here:

      1. Karine

        Fenbendazole 500 called panacur here in the Netherlands is an antiworm protocol for 3 days. I guess the high 3-day dose is to kill off the worms. However for a anticancer protocol not more than 222mg three times a week with a few days off. Am I right? 50mg per kg is max, fog me 60 kg it is 300mg. Weird that dogs around 45kg get the same dosage! Could you confirm the dosage for a 60kg woman? I am 46 years old and healing from an auto immune disease. I had a worm die off in my stool during my prolonged fast.

        1. fenbendazole

          Hello Karine,
          A 60kg person with cancer should take 222mg per day, 6 days a week, with one day off. You can verify all dosage details by entering your information into our dosage calculator, which you can find here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/.

    Hi Rachel..can you tell me the name and how to order the reputable company that is selling the 444 Capsules please?

  231. Mike

    Hi – I’m hoping you can answer a query I have regarding taking Fenbendazole while having chemo. I have stage 4 castrate resistant metastatic prostate cancer and am about to start chemotherapy (Docetaxel) in the next couple of weeks. I intend to fast prior to having chemo (36 hours) and 24 hours after chemo.

    Can I take Fenbendazole during this fast or should I wait until I’ve broken my fast?
    I’m aware that research has shown the Fenbendazole has been shown to break down the scaffolding of the microtubules, which enables the chemo to be more effective.

    Many thanks.

    1. fenbendazole

      Dear Mike,
      Thank you for your question. We would like to emphasize that fasting can pose a significant physical strain and is not recommended. Fenbendazole is absorbed through the digestive tract into the bloodstream; therefore, fasting can inhibit metabolism, reduce the efficacy of fenbendazole, and significantly strain the liver.
      Moreover, it is advisable to discontinue fenbendazole a few days before, during, and after chemotherapy sessions.

  232. Margaret

    Is it possible that 7 doses of 222 mg of fenben can cause dizziness in an 86-year-old with lung cancer who has a 54 GFR kidney result due to recent CT scans with contrast?

    1. fenbendazole

      Hello Margaret,
      Fenbendazole is generally recognized as a safe and well-tolerated drug, and it is not typically known to cause dizziness. Considering the patient’s age and the nature of their illness, it is more probable that these symptoms are manifestations of the disease itself rather than side effects from Fenbendazole. To confirm this, you could pause the administration of Fenbendazole for a few days and observe the patient’s condition closely. If there is an improvement, you may resume Fenbendazole treatment at half the previous dose and incrementally increase it. Additionally, it is important to regularly monitor the patient’s health through blood tests and checks on liver enzymes to ensure overall safety and effectiveness of the treatment.

  233. Tom

  234. Anthony

    Hello, although I have struggled with constipation over the past thirty years, it has gotten worse over the past year. I am lucky when I have a bowel movement every day or every other day if a handful of nuggets come out. After much research, I am hoping it is due to parasites.

    Question: If I take the protocol of fenbendazole listed on this site after killing off the parasites, will this help with my constipation issues?

    The doctors I have seen over the years don’t have an answer, and I am desperate!

    Thank you in advance!

    1. fenbendazole

      Hello Anthony,
      If you’re experiencing constipation along with symptoms like abdominal pain, unexplained weight loss, or fatigue, and there’s reason to suspect a parasitic infection (such as recent travel to areas with prevalent parasitic infections or exposure to poor sanitation), it might be appropriate to consider a parasitic cause.

      Fenbendazole, an antiparasitic medication commonly used in veterinary practice, can effectively eliminate many types of parasites from the body. By clearing the infection, it may indirectly alleviate associated symptoms such as inflammation and intestinal distress caused by the parasites.

      Do not forget to consult with your doctor about taking laxatives daily till your constipation improves. A natural remedy for constipation is eating prunes.

  236. Jan

    I wish only to try fenbendazole for a preventative. I’m not with a diagnosis. Will fenbendazole hurt me? and if I only weigh 135, should I take less?

    Should I take fenbendazole before or after a liver cleanse? Thanks, and yes, I appreciate your expertise.

    1. fenbendazole

      Hello Jan,
      There is no specific requirement to perform a liver cleanse before starting Fenbendazole. Fenbendazole is generally considered safe and well-tolerated, and additional measures such as liver cleansing are not necessary prior to its use.
      We recommend that you use our dose calculator. In the Protocol section, select the “Cancer Prevention Protocol.” The dose calculator will determine the required amount of Fenbendazole and the schedule of use according to your body weight. You will also find all the necessary information related to the use of Fenbendazole there.
      Side effects of Fenbendazole in humans are not well-documented. In rare cases, when Fenbendazole is used for a long time, it can cause stomach upset or diarrhea in a small portion of people.

    1. fenbendazole

      Hello Howard,
      Based on scientific evidence and preliminary studies, fenbendazole has gained attention for its potential anticancer properties. It can be suitable for almost all types of cancer. The body’s response to treatment depends on many factors, including the type and stage of the cancer, the genetic makeup of the cancer, general health and immune system, lifestyle factors, the presence of metastasis, physiological factors, and more.
      There is evidence to suggest that fenbendazole may have a positive effect in the treatment of mucosal melanoma.
      If you decide to use fenbendazole, you can use our dose calculator to determine the correct dose based on your body weight.
      The dose calculator can be found here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      It is also important to monitor your health regularly with blood tests.

    I was recently diagnosed with Bowel cancer that has metatised in the Liver, I am confused as to how many days to take the Fenbendazole, 3 or 7?, so many diffent sites have these 2 different days so now I am not sure, I have been taking it every day for the last 9 days, any help appreciated.

    1. fenbendazole

      Hello June,
      Please use our dose calculator and select “cancer treatment” in the “Fenbendazole for” section. You can find the dosage calculator here:https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      It is important to rest at least one day a week, especially if your cancer has spread to your liver. Regularly check your liver enzymes and monitor your general well-being to ensure the treatment does not harm your health. This makes taking short breaks necessary.
      All the information you need, including the required dose according to body weight, the administration schedule, and additional supplements we recommend taking with Fenbendazole, can be found in the dosage calculator.

      Hello David,
      Based on scientific evidence and preliminary studies, fenbendazole has gained attention for its potential anticancer properties. It may be suitable for almost all types of cancer, including Myelodysplastic Syndromes (MDS). The body’s response to treatment depends on many factors, including the type and stage of the cancer, the genetic makeup of the cancer, general health and immune system, lifestyle factors, the presence of metastases, physiological factors, and more.
      There is some evidence suggesting that fenbendazole may have a beneficial effect in the treatment of Myelodysplastic Syndromes (MDS).
      If you decide to take fenbendazole, you can use our dose calculator to determine the right dose based on your body weight. The dosage calculator can be found here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      It is also important to monitor your health regularly with blood tests to ensure the treatment is safe and effective.

      People diagnosed with MDS may need to have routine blood work done to decide whether they need blood transfusions or additional treatments. Fenbendazole may help you improve your MDS or prevent it from progressing to other blood cancers, however, do not ignore the care of your hematologist.

    What is the protocol if you have Fenbendazole 444 and not 222?

    1. fenbendazole

      Hello Lynne,
      If our dose calculator determined that the required dose of Fenbendazole for you is 222 mg, and you have 444 mg capsules, powder, or another form of Fenbendazole, you can simply divide the 444 mg in half to obtain the correct dose of 222 mg. This ensures you are taking the appropriate amount as calculated for your specific needs.

  246. Mike

    I want make sure I’m taking the right amount. I have prostate cancer. I’m 200 lbs, Joe’s protocol says 222mg, but the dosage calculator says 444mg for a 200 lbs person. I assume it’s 444 a day? And can I take the 444mg capsule once a day or do the 222mg capsule twice a day? or does it matter?

    Thank you!

    1. fenbendazole

      Hello Mike,
      A person weighing 200 lbs should take 444 mg of fenbendazole daily for 6 days (Monday-Saturday). It is sufficient to take this dosage once a day; there is no need to split it into multiple doses. For optimal absorption, we advise taking fenbendazole with or after meals.

  247. Sky

    Thanks for this detailed informative blog that we have learned a lot about fenbendazole. Looks like my aunt will need to take regular breaks option to protect her liver since Milk Sthistle, Silymarin or TUDCA all cause her constipation. (Just Googled that human body only has one liver. ;-))

    “Take liver tests to determine if you need a three to six week break from fenbendazole. You should monitor liver health (AST / ALT liver enzyme levels). If the tests are higher than 2-3 times the norm, discontinue therapy. Taking regular breaks, milk thistle, or silymarin can prevent this from ever happening.”

  248. Shane

    Hello! I’ve just ordered 2 bottles of 222mg from FenBen lab which will be delivered today. My dad has glioblastoma and just recently had a check up after his surgery of nearly a year ago that his tumour has come back and they say he has about 2 months.
    I’m hoping this fenben can potentially help him.
    He weighs 111kg and your calculator says to give 444mg.
    Would that be that amount every day with no breaks, or shall I give him 222mg every day? Hope to hear from you very soon, regards,

    Shane

    1. fenbendazole

      Dear Shane,
      To achieve the required 444mg per day, simply give your dad two 222mg capsules of Fenbendazole. Regarding the usage schedule, the calculator will provide guidance on how many days per week to administer Fenbendazole. Typically, your father should take Fenbendazole daily from Monday to Saturday, then skip Sunday, and continue this weekly cycle.

  249. Janet

    Hi I have a 3cm tumour on my pelvis wall, probably a lymph node. 20 years ago I had total abdominal hysterectomy that was cancerous but did not require chemo. Consultants have told me it could be very difficult to remove so they may end up just doing a biopsy. As I would not want Chemo or radiation I see no point in having a serious operation that may disturb a possibly malignant tumour without removing it. Has there been any success in dealing with endometrial tumours with Fenbendazole. Many thanks for any help you can give me.

    1. fenbendazole

      Dear Janet,
      Fenbendazole has been suggested for the treatment of various types of cancer, including endometrial tumors, as evidenced by several scientific studies and reviews. However, the effectiveness of the treatment can vary significantly based on multiple factors, including the stage of the disease, the location of the cancer, the overall health of the patient, and how the cancer responds to treatment. It is difficult to predict whether Fenbendazole will be effective in your specific case.

      It may help halt or even eradicate the tumors. Your best bet is to try it out for 2-4 months and have a follow-up scan to see if you have any positive progress.

  250. Deb

    I ordered FenBen pure capsules from the Happy Healing Store. I have stage four metastatic breast cancer. I have been taking FenBen 7 days a week plus Quercetin, Berberine, Curcumin and CBD oil. Hopefully this works. I also take milk thistle.

  251. Amanda

    Hi, I put my dogs weight in the calculator and it says 444mg, twice the human dose. Can someone please clarify that a dog over about 15kg needs a 444mg daily dose of fenben? If so, is it best to give this in a single or divided dose. I have the pure 222mg capsules, and will it be ok to put them with some coconut oil so she can lick it from my hand before a meal as she does not always eat her meal ? Many thanks 🙏

    1. fenbendazole

      Hello Amanda,
      Differences in required dosages between dogs and humans mainly stem from biological variations in metabolism, body composition, and drug processing capabilities. Dogs typically have a faster metabolism than humans, allowing them to process and eliminate substances more rapidly. Consequently, they might need a higher dose or more frequent dosing to sustain effective drug levels in their bloodstream for therapeutic effects.
      Given these differences, the dose calculator may recommend a 444 mg dose for your dog, which is higher than what would be typical for a human of the same body weight.
      We suggest administering the full 444 mg dose either with or after a meal. You can mix fenbendazole into soft foods like porridge or ground meat. If your dog primarily eats dry food, you could mix the fenbendazole with a little coconut oil and let your dog lick it off your hand. Choose whichever method works best for you and feel free to adding fenbendazole to any appropriate food.

  252. Rachel patterson

    I know of a very reputable company selling 444 instead of 222 in capsule. Is this too strong? They are selling as anti cancer and are much more economical but are a very good company.

    1. fenbendazole

      Hello Jackie,
      We recommend a maximum daily dose of 444mg for Fenbendazole to ensure the treatment is effective without being harmful. Exceeding 444mg per day is not advisable, as it could potentially cause more harm than benefits.
      Regular blood tests and occasional liver enzyme checks are essential while undergoing treatment with Fenbendazole to monitor your body’s response and ensure safety.
      We also suggest using our dose calculator, which can help you determine the appropriate dosage based on your body weight. This tool ensures that you receive the optimal amount for maximum effectiveness.

Would Fenbenzadole helps with this cyst and she has more starting to grow?

    1. fenbendazole

      Dear Tonya,
      Fenbendazole has been explored for its potential to treat various types of cancer. If the cyst on your dog’s neck is confirmed to be a malignant tumor, using Fenbendazole might be an option to consider. It is crucial to monitor your dog’s health closely and conduct regular blood tests to ensure the treatment is effective and to track any potential side effects.

  257. Dr. Patrick Levesque, D.C

    Good morning, I’m one of the « lucky ones » with metastatic cancer to bones in many areas. The spine, some ribs, clavicles, iliac bones and pelvic area, distal portion of knees and testicles almost calcified. I’m on Casodex, Lectrum and taking ivermectin from June on, just after the DX was made. I refused the conventional approach for obvious reasons. I came across your vidéo and started checking all this protocol to find out in one of the questions asked, that if Mets are present, fenben might not work as good or results may not be what’s expected. Can you enlighten me on this as I’m getting all ingredients ready to start this protocol. CBD might be difficult to get as from Covid BS on, this third world country has become a fifth world one, like everywhere else you might say. Progress they call that!!! So, the clock is ticking and I need help before the oncologist starts to brag and flicks her suspenders and drops me off board because I don’t want that stuff, or at least try to avoid it like pest! Thanks for your quick response and help!

    1. fenbendazole

      Hello Dr. Patrick,
      Indeed, like many cancer treatments, Fenbendazole tends to be most effective on primary cancers and in their early stages. As cancer progresses to more advanced or metastatic stages—such as stages 3 or 4—the challenges increase significantly for any treatment to make a substantial impact. This is true for both conventional treatments, such as chemotherapy, and alternative methods like Fenbendazole.
      It is important to recognize that while early-stage cancers are generally more manageable and potentially curable, this does not mean that advanced or metastatic cancers should not be pursued with treatment. There are numerous cases where individuals have achieved remission from stage 4 or metastatic cancer, highlighting the importance of continuing treatment regardless of the cancer stage.
      The effectiveness of any treatment, including Fenbendazole, depends on a range of factors, not just the stage and location of the cancer. These factors also include the overall health of the patient, their immune system status, and how their body responds to the treatment. Therefore, it is difficult to precisely predict how Fenbendazole will perform in any specific case without considering these individual variables.
      Please note that fenbendazole, along with Casodex and Lutetium, is metabolized by the liver. Regular monitoring of liver function is crucial to prevent toxicity and ensure that all medications are working effectively without harmful interactions. Adding milk thistle to your treatment protocol might help in supporting liver health.
      Be vigilant for any new or worsening symptoms, as they may indicate potential drug interactions or side effects.

  258. Ronnie

    Has anyone used this on Glioblastoma and worked?

  259. Lea Duncan

    My husband has Stage IV liver cancer. His liver enzymes are as follows: ALP is 623, AST is 78, and ALT is 17. He has not started the treatment as he is scared for his liver. You stated above that if AST/ALT is 2-3 times normal to stop. He was going to start but are his levels too high? We were going to do 500 mg TUDCA for liver instead of milk thistle.

    1. fenbendazole

      Hello Lea,
      The ALP (alkaline phosphatase) indicator is a critical focus based on numerous studies. ALP, an enzyme prevalent throughout the body, is primarily found in the liver, bones, kidneys, and digestive system. It is essential for processes such as the breakdown of proteins, digestion, and bone formation. A normal ALP level typically ranges between 44 and 147 IU/L.
      Given that your husband’s ALP levels are elevated, it is advisable to avoid any medications that could further impact liver function. It would be prudent to retest after some time. If the levels return to the normal range or are slightly elevated, considering the inclusion of fenbendazole in the treatment protocol might be feasible.

      Fenbendazole is generally recognized as a safe and well-tolerated drug. However, combining it with afatinib is not standard practice and should be approached with caution. Both medications are metabolized in the liver, and using them concurrently could potentially overburden the liver’s processing capacity. This might result in an accumulation of the drugs in the body, potentially increasing side effects.
      To mitigate the risk to liver function, incorporating Milk Thistle into your treatment plan may be beneficial, as it is known to support liver health.
      If you are considering combining these treatments, it is essential to closely monitor for any adverse reactions or interactions. Regular blood tests should be conducted to check liver function and the levels of the medications to ensure safety and effectiveness.

    Hello,
    My husband was diagnosed with CMML leukemia and had a bone marrow transplant nearly 1 1/2 years ago. He fell out of remission last November and started the same treatment again. He ended up getting a fungal infection that we are dealing with right now and his chemotherapy is on hold right now due to his immune system. I’m wondering your thoughts about fenbendazole
    for him in this situation. Thank you…

    1. fenbendazole

      Hello Mary,
      Fenbendazole is considered for use in treating a broad spectrum of cancers, including CMML leukemia. However, like any medication, it can cause side effects, particularly in individuals with a weakened immune system, such as your husband. It is essential that he undergoes regular blood tests and closely monitors his health while on Fenbendazole.
      Additionally, it is important to pause Fenbendazole treatment around chemotherapy sessions—if the doctors approve chemotherapy, make sure to stop Fenbendazole two days before, during, and after the treatment sessions.
      Regarding the fungal infection, it is important to note that Fenbendazole does not possess antifungal properties and is not suitable for treating fungal infections. Such infections are caused by various fungi and require specific antifungal medications that target the cells of the fungi. Please consult your husband’s healthcare providers for the appropriate treatment options for his fungal infection.

    What is the longevity of the capsule or powder form? I realize legally they must have an expiry date but what is the realistic longevity for the product?

    1. fenbendazole

      Dear Jake,
      The shelf life of Fenbendazole varies depending on the manufacturer and the specific formulation of the medication. The expiration period may differ due to the various additives present in the product. Typically, pure Fenbendazole is valid for about two years.
      You can usually find the expiration date on the product label or packaging. It is crucial to check this date before use to ensure the medication remains effective and safe.
      Using the medication past its expiration date is not recommended, as it may lose its effectiveness and could potentially be unsafe.

  264. Tammy

    Dear fenben my husband has had prostate cancer had treatments and it came back in lungs and some in bones. Your chart said he should take 444 mg for 210 body weight. Is that right or just 222 would work. And also should he do 3 days or 6 . Tammy

    1. fenbendazole

      Dear Tammy,
      Based on your husband’s body weight, he should take 444 mg of Fenbendazole per day. He should follow this regimen for 6 days a week, taking one day off. Additionally, consider adding supplements such as Milk Thistle, Curcumin, CBD, and Vitamin D to his protocol. These supplements can help strengthen his body, boost immunity, and provide overall liver support.
      Remember to schedule regular blood tests and monitor his general well-being to ensure the treatment proceeds smoothly.
      You can always verify the dosage using our dose calculator:

    does this work for liver and stomach and pancreatic cancer i need to know like asap

    1. fenbendazole

      Dear Chritina, thank you for your question.
      There are several scientific articles and laboratory studies indicating that fenbendazole may be effective in combating cancers, including liver, stomach, and pancreatic cancers. However, its effectiveness in your specific case cannot be guaranteed. The success of fenbendazole as a treatment depends on numerous factors, such as the patient’s overall health, immune system strength, the cancer’s resistance to treatment, the stage of the disease, and the body’s response to the treatment.

  266. JRS

    My local dispensary says 1 drop oh CBD oil they sell is 1 mg. That would mean 25 drops. Am I missing something?

    1. fenbendazole

      Hello JRS,
      You calculated correctly. The total daily dose of CBD needed is approximately 25mg. If each drop of your CBD contains 1mg, you will need 25 drops to reach the desired 25mg dose.

  267. Susan

    I got the Fenbendazole 444 no CA that I know of just a family history. Can I take the 444 every other day or should I split the capsules?

    1. fenbendazole

      Dear Susan,
      If your required dose is 222mg, you should split the 444mg capsule into two halves and administer Fenbendazole following the dosage schedule provided by the dose calculator.

  268. Aiden

    I bought 150mg tablets from India. I used the calculator and it says I need 444mg daily due to my weight (100kg) is that correct? Since they are tablets should I just take 3x150mg daily?

    1. fenbendazole

      Dear Aiden,
      Yes, your calculations are correct. Based on your body weight, you need 444mg of fenbendazole. If you have 150mg tablets, you will need to take 3 tablets per day. Remember to take the entire dose once a day with or after food.

  269. Jason

    I have a question. My Son is 14 years old he was recently diagnosed with T-ALL. What is the best regimen for him? He started chemo 2 weeks ago. Thank you!

    1. fenbendazole

      Hello Jason,
      Fenbendazole may be used effectively in the treatment of cancers, including T-cell acute lymphoblastic leukemia (T-ALL). However, we cannot predict how your child’s body will react to such treatment. The prognosis for T-ALL treatment varies depending on several factors, including the patient’s age, response to initial treatment, and specific genetic abnormalities of the leukemia cells.
      If you are considering using fenbendazole for your son, monitor his health regularly with blood tests and medical evaluations to detect any adverse effects early. Additionally, Fenbendazole should be stopped two days before, during, and two days after chemotherapy.

  270. Winnie

    I don’t understand thesec sizing recommendations. You said 1 gram per 10 lbs. So that would be 100mg per 10 lbs which would be 1500mg for a 150 lb person. Then you say that instead you could take 222mg for 3 days. Next you say I don’t understand thesec sizing recommendations. You said 1 gram per 10 lbs. So that would be 100mg per 10 lbs which would be 1500mg for a 150 lb person. Next you say that In practical terms, try doses of 750 mg or 375 mg. This is extremely confusing. In addition, everywhere on the Web with dosageb recommendations for animals say 50mg/kg. I have a member of my family who just cannot get rid of pinworm. Over the last 3 months, multiple rounds of other medications (both Albendazole and pyrantel pamoate) have not gotten rid of it and we are desperate, but we have been unable to find dosing information for humans, and we have searched pretty much every corner of the internet for weeks. I was so relieved to find this site, but am still as confused as ever. Our whole household has been vigilant in hygiene to the extreme. We have a bottle of 222 here but don’t want to waste it by giving an insufficient dosage. Please, we are desperate! Thank you.

    P. S. I wish I had known about this a year ago when I lost my dog, the love of my life, to cancer. I am very happy to have this information for the future, should myself or a loved one get the dreaded diagnosis.

    1. fenbendazole

      Dear Winnie,
      We will try to help you. The dosage is very simple. Use our dose calculator by clicking on this link: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Measure your body weight and choose the anti-parasite treatment protocol. The calculator will determine the daily doses of Fenbendazole you need and the schedule to follow.
      Different manufacturers have varying amounts of Fenbendazole in their products, which can cause confusion. Please read the package label carefully to find out how many mg of Fenbendazole your medicine contains. For example, Fenben Lab offers simple dosages with 222 mg or 444 mg capsules or powder. For Panacur C, you would need a 1g packet to get 222 mg of Fenbendazole. For Safe-Guard suspension, you would need 2.22 ml to get 222 mg of Fenbendazole.
      We sincerely hope this helps you understand how to choose the correct dose. If you have any further questions, we will be happy to answer them.

    Just learned of someone who is cancer free after this protocol. I have friend just diagnosed with multiple myeloma. Would this work. I also got covid was out of the hospital 1-15-23. I’m respiratory failure. I’m off oxygen but still have COP (cryptogenic organizing pnuemonia). No treatment available. Slight improvement on last 2 CT. It’s origins can’t be found so it’s not treatable. It grows nothing as far as bacteria. Do you think this would be a good treatment option?

    1. fenbendazole

      Dear Mary,
      Fenbendazole is gaining attention for its potential in treating various types of cancer, including multiple myeloma. This protocol might be beneficial for your friend in their fight against the disease. Fenbendazole’s mechanism of action shows promise in potentially killing cancer cells, partially reducing tumor size, or at least slowing the disease’s progression. However, the effectiveness of fenbendazole can vary depending on several factors, including the stage of the disease, your friend’s overall health, immune system strength, and individual response to the treatment.
      Regarding cryptogenic organizing pneumonia (COP), it is a rare and complex condition primarily treated with corticosteroids, although other immunosuppressive therapies and supportive care might be necessary. Unfortunately, there is no scientific evidence supporting the use of fenbendazole for treating COP. Its efficacy in treating respiratory conditions like COP has not been proven.

  272. Alex

    Hi,
    My father was diagnosed with stage 4 gastric cancer metastatic to the liver. Do you have any guidance on how to alter the protocol to keep his liver safe?

    1. fenbendazole

      Dear Alex,
      Thank you for your question. Maintaining liver health is crucial when using fenbendazole, especially for patients with liver metastases. Several natural remedies can support liver health: Milk Thistle (Silybum marianum) for liver protection; Turmeric (Curcumin) for anti-inflammatory and antioxidant effects; N-Acetylcysteine (NAC) to aid detoxification; and Dandelion Root for liver function and digestion support.
      Lifestyle adjustments are also important. Ensure your father eats a diet rich in fruits, vegetables, whole grains, and lean protein. Avoid processed foods, excessive alcohol, and fatty foods. Staying hydrated by drinking plenty of water helps flush toxins from the body, and regular physical activity supports overall health, including liver function.
      Regular blood tests are necessary to monitor liver enzyme levels and overall liver function to ensure everything is on track.

  273. Nancy

    Wanting to know if fenbenzole would help with my Lupus. I haven’t had a Lupus flare in 3 years and I’m on my third immune suppressant medication called Leflunomide 10mg. Have been taking this medication for the past 3 years. Doc switched me to Leflunomide because the previous 2 immune suppression medications gave me significant side effects. Fingers crossed I haven’t had any side effects. I do get blood work done every 4 months to check my liver enzymes. (Only one time that did I have a slightly elevated level). Do you think I’would be able to take fenbenzole? And if I could take it, would it be at a lower dose?

    1. fenbendazole

      Dear Nancy,
      There is currently no scientific evidence to support the effectiveness of fenbendazole in treating autoimmune diseases such as lupus (systemic lupus erythematosus or SLE). Standard lupus treatment typically includes immunosuppressive drugs, anti-inflammatory medications, and other therapies to manage symptoms and prevent disease progression.
      Both leflunomide and fenbendazole can affect liver function. Leflunomide is known for its potential hepatotoxicity, and fenbendazole can also impact liver enzymes. Combining them might increase the risk of liver damage, so regular monitoring of liver function tests is essential.
      While there is no concrete evidence of severe interactions between leflunomide and fenbendazole, their combined use requires careful medical supervision due to potential cumulative effects on the liver and immune system. Using fenbendazole to treat lupus would be highly experimental, and its effectiveness is uncertain.
      If you decide to take these two drugs together, regular blood tests and monitoring of liver enzyme levels are recommended.

  274. J.E.

    Which protocol would be recommended? My wife has stage 3 ovarian cancer. Her CA125 numbers are at 157. Afraid to tell her doctor that she is on fenben because I know what his response will be. she is currently taking chemo doxil with zero bev.

    1. fenbendazole

      Hello J.E.
      Most traditional medical practitioners do not endorse using off-label drugs for cancer treatment. Consequently, patients bear the full responsibility for their treatment decisions, including dosage and drug administration.
      Regarding the co-administration of Fenbendazole and Doxil, we recommend discontinuing Fenbendazole two days before, during, and two days after Doxil administration.
      For dosing information, we recommend using our dose calculator to determine the appropriate Fenbendazole dose for your wife, including the administration schedule and any additional supplements needed.
      You can find the dose calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Additionally, regular blood tests and monitoring your wife’s overall condition are crucial while using Fenbendazole.

    Hello I have primary liver cancer which is aggressive as for as know it has not metastasis to other organs , but it is extensive in my liver, I do a lot of fasting, at moment I am having chemo I hated it, but my choices where very limited, I take some supplements also ones that are for liver support such as Milk Thistle also Tudca , my Alkaline phosphate is very high, but rest of my liver enzymes are in the normal range, i would like to know if the original Fenendazole version three days taking 222g it then four days of would i be right for me,
    Thank you

    1. fenbendazole

      Hello Lane,
      Fenbendazole is generally considered a safe and well-tolerated drug. However, since liver cancer patients often have compromised liver function, it is crucial to be mindful of potential hepatotoxicity (liver toxicity) with any medication. Therefore, we recommend regularly checking liver enzyme levels and monitoring your overall well-being while taking Fenbendazole.
      Continuing to take liver support supplements is advisable.
      For specific dosage guidelines, we suggest using our dose calculator, which will help you determine the optimal schedule and dosage of Fenbendazole based on your weight and other factors.
      Since we do not have your exact weight, we can not provide a precise dosage.
      Please enter your details into the calculator below to get an accurate dosage recommendation.

    Now in the comment sector it is written 222mg all over. What is the right dosage please?

    Regards from Germany
    Wilfried

    1. fenbendazole

      Dear Wilfried,
      We are here to help you. Based on your body mass, you need a dose of 444 mg of Fenbendazole.
      If your weight decreases to 90 kg, you will need to reduce the dose to 222 mg.

  278. William

    if the capsules are 500mg but the recommend size is 222mgs how come you don’t sell them in that size and taking capsules at that size how much more dangerous is it.

    1. fenbendazole

      Hello William, Thank you for your question.
      Fenbendazole is available from various manufacturers, each offering different dosages. However, you can find suppliers that provide the specific doses you need, such as 222 mg or 444 mg. You can view a list of reliable suppliers here: https://www.fenbendazole.org/suppliers/
      If you have already purchased 500 mg capsules, you can divide them in half to get a dose of 250 mg. This slight difference will not cause any harm.

    I’m a 51 year old breast cancer survivor and am looking to prevent a future recurrence. I’d also like to cleanse any parasites. I bought the 150 mg tablets from an overseas company and it is the Merck brand. I am wondering if the 300 mg daily is okay versus the 222 mg?
    Thank you so much for creating this website with this information!

    1. fenbendazole

      Hello Stephanie,
      If possible, split the 150mg tablet into two halves. Then, take one and a half tablets daily, which will provide you with 225mg of Fenbendazole. If splitting the tablets is not feasible, take 300mg per day. Remember to regularly check your blood tests and monitor your overall well-being while using Fenbendazole.

  283. Veronica

    I have anal squamous cell carcinoma. Only changed diet , no sugar no dairy no grain. Would fenbendazole help to further control growth before ir encroaches on important structures. One swollen lymph gland but no metastises. I am well but old 54 kg but would like to resolve or at least hold back more. Please advise

    1. fenbendazole

      Dear Veronica,
      Fenbendazole is widely used and has shown efficacy in treating various types of cancer, including squamous cell carcinoma. Its effectiveness is influenced by several factors, such as the patient’s overall health, immune response, treatment response, and the cancer’s stage and location. These factors collectively impact the treatment outcome, potentially enhancing or diminishing the cancer’s responsiveness to therapy.
      Maintaining a diet free of sugar, dairy, and grains is advisable, as it can help reduce inflammation and limit glucose availability to cancer cells, thereby inhibiting their growth. Additionally, regular blood tests and general health check-ups are essential to monitor the progress of the treatment and ensure it is proceeding smoothly.

    When reading about possible side effects in humans, when i see that, ” Fenbendazole binds beta-tubulin subunits of microtubules, interfering with their polymerization.”, what effect does this have on the health in the accute sense, and in the long term sense? Does this have forward-cascading effects on health? What is this saying in plain english, non-medical terms? Is this a temporary thing? Does this only occur locally to the drug’s direct contact with cells/tissues, or does it affect all cells/tissues/meterials throughout the body?

    1. fenbendazole

      Hello and thank you for an excellent question.
      Fenbendazole works by binding to beta-tubulin, a building block of microtubules. Microtubules are tiny structures within cells that help maintain their shape, assist in cell division, and transport materials. By disrupting microtubule formation, fenbendazole interferes with these critical processes.
      Notably, fenbendazole targets only parasite and cancer cells. This selectivity is shared by other de-wormers such as mebendazole and albendazole. These compounds are well-studied and used daily by millions of people. In some cases, individuals use these drugs for years (e.g., for echinococcosis) and generally tolerate them well, often without any side effects.
      Compared to albendazole, fenbendazole is milder and better tolerated at the recommended doses of 222-444 mg. Doses of 1000-2000 mg, as suggested by some fraudulent sources, are too large for daily, continuous use.
      In the short term, fenbendazole can cause transient and reversible gastrointestinal issues, mainly diarrhea. This side effect occurs in a very small percentage of people (~1%) and typically resolves within a day or two.
      Long-term use of fenbendazole can lead to asymptomatic liver enzyme elevations. In blood work, this appears as an increase in AST and ALT enzymes, indicating liver stress. This usually occurs when people do not adhere to the recommended doses of 222 or 444 mg and do not take weekly breaks. Higher doses (>1000 mg daily) without breaks, as advised by some “Facebook experts,” can also cause this issue more quickly. If liver enzyme elevations occur, they are entirely reversible and return to normal after a 1-2 week break from fenbendazole. Taking a daily milk thistle supplement can also help prevent this side effect.
      It is worth noting that this liver enzyme elevation is similar to what can happen in people taking Tylenol (paracetamol or acetaminophen) for daily pain relief. Many medications have a similar benign side effect that resolves on its own.
      Other side effects such as impacts on the brain, bone marrow, skin, gastrointestinal mucosa, or hair loss are not associated with fenbendazole use and are mostly related to chemotherapy treatments.
      In summary, fenbendazole is safe for long-term use when taken in the correct doses and schedule. All mild side effects are reversible and will not cause any lasting health damage.

  285. Nicola

    I dont have cancer or any tumours but am very much into preventative nutrition and lifestyle against cancer. I just wonder please, does Fen interfere with any other supplements as I take quite a few each day? Do you think its also an idea to give our dogs your prevention protocol regularly?

    1. fenbendazole

      Hello Nicola,
      We are pleased to see you prioritizing your health and maintaining a healthy lifestyle. Regarding your inquiry about taking supplements with Fenbendazole, we can confirm that Fenbendazole is generally safe and well-tolerated. It is often used alongside various supplements and cancer medications. Most people do not experience side effects from Fenbendazole; however, as with all medications, incorrect dosages or schedules of supplements can lead to temporary side effects. We recommend regular health monitoring and blood tests when combining Fenbendazole with supplements to ensure safe usage.
      For your dog, the frequency of deworming for adult dogs depends on their risk of parasite infection. This can range from once a month to once a year.

  286. Mary

    I live in Australia, maybe this is why, whatever I try, I can not obtain the original American Panacur or Safe-Guard from Merck. Last time I bought Safe-Guard powder that was supposed to come from the US via an Australian supplier – it did have Merck printed on. However, it also had API made in China printed on the side of the box. How disappointing! Does anybody else has a similar experience?

    Fenben that you can order via this website seems to come from Lithuania. Is it the same quality like the American one? Could please someone clarify this. Thank you.

    1. fenbendazole

      Hello David,
      To our knowledge, Fenben Lab produces fenbendazole with an impressive purity level of 99%. This high-purity material comes from a reliable source, which is why we recommend them as one of the top suppliers of Fenbendazole.
      As an independent organization, Fenben Lab is not regulated by the FDA or the European Medicines Agency (EMA) since they sell Fenbendazole as a chemical rather than a veterinary product.
      Based on our understanding, Fenben Lab is a reputable organization with years of experience and positive reviews.

  288. Hugo

    Hi there!
    I’m using Fenbendazole for parasite and the calculator says to use 222mg with my weight.
    I cant get the capsules delivered to my far away 3rd world country…
    So I would like to ask what amount in the liquid in suspension (100 mg / ml) is the equivalent of a 222mg capsule? I can actually have an accurate measurement in ml (from 0 to 50ml) with a test tube.
    Best regards!

    1. fenbendazole

      Hello Hugo,
      If you have the medication in liquid form, and the concentration is 100 mg of fenbendazole per milliliter, you will need to administer 2.22 ml to achieve a dose of 222 mg of fenbendazole. This ensures you get the precise amount needed based on the concentration of the liquid medication. By measuring out 2.22 ml, you can accurately provide the required 222 mg dose of fenbendazole.

  289. Dragos

    Hi
    I have a member of my family diagnosed with lung cancer metastasis stage and doesn’t want to do chemotherapy or anything related to that .
    And i was wondering if FENBENDAZOLE can help just by itself + cbd oil and curcumin ?

    1. fenbendazole

      Dear Dragos,
      Fenbendazole is widely used and often effective in treating many types of cancer, including lung cancer. However, its effectiveness for your family member cannot be guaranteed because it depends on many factors, such as the type and stage of the cancer, the patient’s general health, genetic factors, aggressiveness of the cancer, lifestyle and diet.
      If your family member chooses to use fenbendazole in combination with CBD and other supplements instead of conventional treatment, careful monitoring of their general well-being and regular blood tests are essential. Regular physical examinations and monitoring of symptoms such as cough, shortness of breath, pain, and fatigue can help gauge the effectiveness of treatment.
      In addition, certain blood biomarkers can indicate cancer activity and response to treatment. If the treatment seems to be working, continue it until the cancer is completely gone.

    anyone with hairy cell luekemia that have had success taking fenbendazole

  291. Janice

    My cancer has returned after 5 years. I’ve been taking the 22mg of fenbendazole for 5 days so far. I also have large gallstones and am not sure if I can take the Bio-curcumin. My doctor won’t even discuss it. Have you any information about this?

    1. fenbendazole

      Hello Janice,
      Curcumin has anti-inflammatory properties that can help reduce inflammation associated with gallstones and enhance overall liver and gallbladder function.
      While biocurcumin offers these benefits, it should be used with caution in patients with large gallstones due to potential risks related to increased bile production and gallbladder contraction.
      In some cases, curcumin can stimulate bile production. For individuals with large gallstones, this increased bile flow may lead to complications, such as gallstone migration, which can cause blockages or other issues. Additionally, some research suggests that curcumin may have a cholecystokinetic effect, meaning it can stimulate the gallbladder to contract, posing risks for those with large gallstones.

  292. Laurel

    My husband had a GBM tumor removed from his right temporal lobe. Of course they got most but not all. He will be starting radiation soon. Can I do this protocol during the radiation treatment. Will any of the part of the protocol react negatively with the radiation or chemo when he has to do it?

    1. fenbendazole

      Hello Laurel,
      We recommend not taking Fenbendazole two days before, during, and two days after radiation or chemotherapy to avoid additional strain on the body and liver. This is only a recommendation, and the decision to use Fenbendazole during radiation is up to you and your husband. Radiation therapy can be stressful, causing fatigue, skin reactions, mouth ulcers, difficulty swallowing, dry mouth, taste or voice changes, cough, shortness of breath, nausea, vomiting, diarrhea, urinary symptoms, and hair loss. Therefore, it is better to avoid off-label medications during this period. If your husband still decides to use Fenbendazole with standard treatments, it is crucial to closely monitor his well-being and have regular blood tests.

      The differences in fenbendazole dosages for dogs and humans primarily arise from variations in metabolism, physiology, and the intended use of the drug. These variations exist because dogs metabolize substances differently than humans. As a result, a dog’s metabolism may necessitate a higher dose of fenbendazole to achieve the same therapeutic effect, explaining why a 100-pound dog might require a much larger amount than a human.
      Additionally, the absorption, distribution, and elimination of fenbendazole can differ significantly between species. This means dogs might need higher doses to reach effective levels of the drug in their system. The prescribed duration of fenbendazole treatment can also vary based on the condition being treated. For instance, dogs might need a five-day course to ensure complete parasite clearance, whereas humans might only require a three-day course depending on the infection’s type and severity.
      Veterinary guidelines are specifically tailored to address the unique needs and conditions of animals. The dosing and treatment duration for fenbendazole in dogs are based on extensive veterinary research and clinical practice, which may differ from medical recommendations for humans. Consequently, higher doses and longer treatment durations in dogs are determined based on what is considered safe and effective for that species, ensuring the medication effectively treats the condition without causing harm.

    I was wondering if it was good to continue regular multi-vitamins including the Quercitin, Zinc, D, C protocol for viruses along with this fen-ben protocol for prophylactic cancer measures or for actual cancer. Just don’t want to create an interaction making this protocol ineffective. Thank you.

    1. fenbendazole

      Hello Vivian,
      Fenbendazole generally interacts well with other supplements and rarely causes adverse reactions. If you believe the supplements you are currently taking are essential, you can continue using them alongside fenbendazole. It is crucial to monitor your overall well-being and have regular blood tests to ensure everything remains within normal ranges. However, if you do not have cancer and are considering fenbendazole as a preventive measure, it can be effective on its own without additional supplements.

  295. Faye

    If someone has liver cancer, can they take this protocol considering the liver is what processes this for the body and
    is it the strongest protocol for how long? 7 days a week for how many weeks or 3 days on, four days off?

    1. fenbendazole

      Dera Faye,
      Whether a patient with liver cancer can use fenbendazole depends on several factors, including the specific type of liver cancer, the patient’s overall health, liver function, and concurrent medications.
      If the patient feels well, can eat and move independently, and their liver enzymes are not elevated or only slightly above normal, they can use fenbendazole but should do so with great caution and responsibility.
      Although fenbendazole is generally considered a well-tolerated and safe drug, it is metabolized in the liver. Therefore, if a patient has impaired liver function, there may be concerns about how well they can metabolize and eliminate the drug from their system. This could result in increased side effects or toxicity.
      For these reasons, it is recommended to carefully monitor the patient’s overall condition and regularly check blood and liver enzyme levels when using fenbendazole.
      Regarding the usage schedule, it is advised to take fenbendazole for six days in a row and then take a one-day break.
      To find out the specific dose and schedule based on the patient’s body weight and the nature of the disease, you can use a dose calculator:

  297. Karen

    Would it be better to take double dose of Fenben 3days on 4days off with active cancer, or better to take a double dose everyday for10days and 2days off?

    1. fenbendazole

      Hello Karen,
      Since we do not have your body weight information, we can not specify the exact dose you will need. However, for using fenbendazole to treat cancer, the recommended regimen is to take it daily for six days (Monday to Saturday), skip the seventh day (Sunday), and repeat this cycle weekly. Fenbendazole should be taken once a day, during or immediately after a meal.
      Please use our dose calculator to determine the appropriate schedule and dosage of fenbendazole tailored to your specific needs. This tool considers your body metrics and the purpose for which you are using fenbendazole to provide precise recommendations. You can find the dosage calculator here:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      We strongly advise against exceeding the recommended daily dose or increasing the frequency of use, as this can elevate the risk of side effects and negatively impact your well-being. The calculator is designed to ensure maximum treatment efficacy while minimizing side effects.

  298. Cameron U.

    The dosage calculator on this page says for my weight to take 444mg as the daily dose. But as I read through most of the information on this protocol everyone seems to be taking 222mg daily. If I do the 6 days a week protocol rather than the 3 days a week should I still double the daily dose or do I really need to double the daily dose at all?

    1. fenbendazole

      Dear Cameron,
      We can not provide a specific dosage without knowing your weight and the purpose for which you are using fenbendazole. Please refer to our dose calculator, designed to help you select the most effective dose based on your body weight and treatment goal.
      For individuals weighing more than 90 kg, the recommended daily dose is 444 mg. This is normal and safe; a lower dose of 222 mg would likely be insufficient and may not yield effective results. If you are using fenbendazole to treat cancer, the recommended regimen is to take it daily for six days, followed by a one-day break.
      If you have any further questions or concerns, please feel free to contact us. We are here to help and will do our best to answer all your queries.

  299. Doug

    I have acquired Fenbendazole Bolus 1.5G (FENTAS 1.5) from an online supplier. It is a 4 tablet blister pack and I presume each tablet is 1.5G but maybe not. Could all 4 tablets equate to 1.5G? I wish to treat myself for parasitic infection. Based on my weight (~200 lbs) and the other parameters of your calculator I am to take 444mg/day. When compared with an animal, why is the dose so small for a human? I used a mortar and pestle to crush one tablet and divided by 3, took 1/3 of one tablet once per day for 3 days and have been off for 5 days. Is this correct? If anything, my symptoms are worse and am now ready to start round 2.

    1. fenbendazole

      Hello Doug,
      To verify if each tablet or the entire blister pack equals 1.5 grams (1500 mg) of fenbendazole, carefully examine the package and all included inserts for specific dosage information per tablet. Medications are typically labeled with the amount per unit (e.g., per tablet, per capsule). Therefore, Fenbendazole Bolus 1.5GM likely contains 1.5 grams of fenbendazole per tablet, meaning a blister pack of four tablets would total 6 grams (6000 mg) of fenbendazole.
      The 444 mg dose chosen for your body weight is correct. However, you should take Fenbendazole once a day for 5 consecutive days. This treatment might need to be repeated after three weeks.
      Regarding the dosage differences between humans and animals, humans metabolize fenbendazole more slowly, thus requiring a lower dose to achieve efficacy. Trust our dosage calculator, which is calibrated to provide the best treatment results with minimal side effects on your body.

  300. Shannon Buchanan

    I possibly have Lymphoma, not sure what kind problems in the groin area. Having a CT Scan on June 26, 2023. I have a lot of the systems of Lymphoma, especially the itchy rash which is driving me crazy. My friend told me about Fenben protocol so I already started doing it and it has been 4 days. I am not hurting like I was in my groin and am not as fatigued but the itchy rash is concerning. I wanted to know about anything topical I could use while I am waiting for the protocol to help take this out.
    Thank you for your help.

    1. fenbendazole

      Dear Shannon,
      Depending on symptom reduction, you will continue the fenbendazole protocol. Managing symptoms, especially an itchy rash, can improve comfort. Try local treatments like over-the-counter hydrocortisone cream to reduce inflammation and itching. Calamine lotion and antihistamine creams containing diphenhydramine (like Benadryl cream) can also help. Use fragrance-free, hypoallergenic moisturizers with ceramides or colloidal oatmeal, and apply pure aloe vera gel for cooling relief. Cool compresses can reduce itching and inflammation. Avoid hot showers, use mild, unscented soaps and cleansers, and wear loose, breathable clothing. If the rash worsens or other symptoms develop, see your doctor immediately.

  302. JAMES K GRAUL

    a dog should take a gram for each ten pounds to deworm. So a 180 pound person if he was deworming would take 18 grams.
    It is done for three days. Has anyone tried this? Seems to me it would be the first thing to try would be to actually deworm yourself using the dose that has proven effective.

    1. fenbendazole

      Dear James,
      Your calculations are incorrect. A dog should not receive 1g of Fenbendazole for every 10 lbs of body weight. For deworming, a 180 lbs dog should receive 4082 mg of Fenbendazole for 5 consecutive days. In contrast, a human weighing 180 lbs should take 444 mg of Fenbendazole for deworming, also for 5 consecutive days.
      This difference is due to the significantly slower metabolism in humans compared to dogs, necessitating different dosages to achieve effectiveness.
      We strongly recommend using our dose calculator. By entering your data into the calculator, you can determine the appropriate dosage and schedule.
      You can find the dose calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      It is essential to follow these guidelines and not exceed the safe daily dose of 444 mg of Fenbendazole for humans. The success of the treatment heavily relies on the correct dosage and schedule.
      We hope this clarifies the Fenbendazole dosage. If you have any further questions, please write to us.

    Regarding prostate with PSA of 74
    What is recommended protocol for this?

  304. Lisa Kruger

    Hello! I am so happy I found your website. I realize the majority of content is focused on cancer treatment. However, I have heard that Fenbendazole has also been used in treatments for hemorrhagic fever. What I am unable to find is any suggested protocol. Any idea who may be able to assist? Any suggestions is most appreciated. Thank you for all you do!

    1. fenbendazole

      Dear Lisa,
      We regret that we do not have any scientific evidence or clinical trials to support the effectiveness of fenbendazole against viruses such as Ebola, Dengue, and Yellow Fever, which cause hemorrhagic fevers, or against any virus. Fenbendazole works through mechanisms that do not target viral replication and does not reduce the symptoms of viral infections.
      Given the lack of evidence for its antiviral properties, using fenbendazole to treat hemorrhagic fever would be considered experimental.
      If you decide to use fenbendazole, please follow the Parasite Protocol. Our dose calculator will help you determine the correct dose and consumption schedule. Be sure to select “Parasites” under “Fenbendazole for” when using the calculator.

  306. Marlo Celico

    Hello! I have stage 3 endometrial cancer that’s spreading. Will this protocol work for me? I have already started the fenben and ivermectin, plus a lot more to my hopefully cancer free life. Thanks I’m advance.

    1. fenbendazole

      Dear Marlo,
      Fenbendazole can potentially be effective in treating various types of cancer, including endometrial cancer. However, its effectiveness can depend on several factors such as your overall health, how the cancer responds to the treatment, your immune system, and the stage or aggressiveness of the cancer.
      We cannot predict how fenbendazole will work in your specific case. It is important to understand that fenbendazole is intended for long-term use, and it may take from 1 to 4 months to observe any initial results. For this reason, we recommend continuing the treatment for at least a few months to determine its effectiveness.
      Additionally, it is crucial to monitor your overall well-being and regularly check blood tests to avoid any potential side effects. This careful monitoring will help ensure that the treatment is as safe and effective as possible.

    From the many experiences of others, I wondered if while on the Fenben protocol, could folks ‘feel’ their cancers dying? X
    Does anyone care to reply and elaborate? I’d appreciate it greatly.

    God bless each and every person!

    1. fenbendazole

      Hello,
      There are reports from individuals using the fenbendazole protocol for cancer treatment who claim to “feel” their cancer’s response to the treatment. These experiences vary widely and can include sensations such as localized pain, changes in the size or sensation of tumors, and improvements in general well-being.
      Some individuals report specific sensations in the area of the cancer, such as tingling, pain, or a sense of “activity,” which they interpret as the cancer being affected by the treatment. A few users have noticed changes in the size or texture of palpable tumors, suggesting a response to treatment. This may involve tumors shrinking, softening, or becoming less noticeable over time.
      Others report improved overall health and energy levels, attributing these changes to fenbendazole’s anticancer effects, such as reduced fatigue or fewer cancer-related symptoms.
      However, the effectiveness of the treatment is not always felt or tangible. The most accurate way to determine the effectiveness of the treatment is through medical tests such as MRI, PET, CT, biopsy or ultrasound, depending on the type of cancer. Regular medical assessments are essential for an objective evaluation of the treatment’s impact.

  309. J

    I bought Safe-Guard “Fenbendazole” to get it really fast and get started. It seems it comes in 1 Gram pouches. Does this mean for 222 mg dose I would divide each pouch into 4? Or would I take the whole packet? It seems like Joe Tippens was saying take the whole 1 Gram packet.

    1. fenbendazole

      Dear J,
      Safe-Guard Fenbendazole is usually available in 1-gram sachets containing 1 gram of powder, with a typical concentration of 222 mg/g. This means you should take the entire packet once a day if your required dose is 222 mg of fenbendazole. Ensure the package indicates 222 mg/g (22.2%) concentration. If you need a higher dose of 444 mg, you would need two packets per day. Check your required dosage and schedule using our dosage calculator: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/

    Hi, Has it shown to be effective on Multiple myeloma or Chronic Myeloid Leukemia?

    1. fenbendazole

      Hello Mily,
      Although research on the efficacy of fenbendazole in multiple myeloma (MM) and chronic myeloid leukemia (CML) is still in progress, there are promising aspects to consider. Fenbendazole has shown potential in preclinical studies across various cancer types by disrupting microtubule formation and inhibiting cancer cell division. While specific studies on MM are limited, these mechanisms offer hope for its potential application.
      Reports of positive outcomes with fenbendazole in treating melanoma cancer are available, such as this story: https://www.fenbendazole.org/melanoma-stage-4/
      The way fenbendazole interferes with cancer cell metabolism and induces cell death holds promise for CML treatment. Though direct evidence is limited, the theoretical foundation is encouraging. Additionally, some cancer patients have reported improvements with fenbendazole, providing optimism for its potential in treating CML.
      While more research is needed to confirm fenbendazole’s effectiveness in multiple myeloma and chronic myeloid leukemia, its potential and the encouraging patient recovery stories are promising.

  312. Tyler

    Has this protocol been found effective against Hodgkins lymphoma?

    1. fenbendazole

      Hello Tyler,
      Fenbendazole is being researched for its potential anti-cancer properties, and some evidence suggests it may be helpful in treating various types of cancer, including Hodgkin’s lymphoma.
      Fenbendazole works by disrupting microtubule function, which is essential for cell division and growth. By interfering with these processes, fenbendazole can inhibit the growth and proliferation of cancer cells. Additionally, it can inhibit glucose uptake in cancer cells, effectively starving them of the energy needed to grow and multiply.
      While there are no definitive studies specifically on Hodgkin’s lymphoma, the mechanisms by which fenbendazole affects cancer cells could potentially benefit patients with this disease. It is important to follow a consistent protocol and regularly monitor your health and progress if you decide to use fenbendazole.

  313. Marsha

    Can you take Fenbendazole everyday with your other supplements?

    1. fenbendazole

      Dear Marsha,
      Fenbendazole is generally considered safe and has a low risk of adverse interactions with most supplements. However, specific interactions may vary depending on the supplements used.
      It is crucial to select the correct dosage and administration schedule for fenbendazole. Some protocols recommend using it in cycles rather than continuously. Therefore, we suggest using our dosage calculator to determine the appropriate dosage and administration schedule for your specific case. You can find the dosage calculator here:
      https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      As with any new medication or supplement, it is important to regularly monitor your health and watch for any side effects. Ensure you have regular blood tests to help the treatment proceed smoothly.

  314. Debbie Newton

    I was diagnosed with
    Triple negative invasive lobular, grade 3 & stage 2
    Possibly positive in auxiliary lymph nodes & maybe spread past that. I am still getting thorough diagnosis to see what exactly I am fighting. Would your protocol work alone or with chemo? I am o etehelmed of what to do. Thank you

    1. fenbendazole

      Dear Debbie,
      You will need to decide which treatment plan suits you best. Many patients opt for a combination of chemotherapy and off-label drugs, while others have seen excellent results by exclusively using alternative treatments. It is challenging to determine the most effective approach for your specific case, as individual responses to treatment vary widely. Factors such as your overall health, immune system strength, the aggressiveness of the disease, and how the cancer responds to treatment all play crucial roles.
      If you choose a combined treatment, remember to stop using fenbendazole 2 days before, during and 2 days after chemotherapy. Additionally, it is essential to closely monitor your overall well-being and have regular blood tests to ensure the treatment is progressing smoothly.

  316. Becky Subrahmanyam

    I have heard that if we are ever attacked with Marburg, that Fenbendazole can be used to treat and maybe as a prophylactic. Have you heard of this for Marburg? And do you know the dosage or the frequency for taking it for Marburg?

    1. fenbendazole

      Dear Becky,
      There is no scientific evidence or established medical recommendations to support the use of fenbendazole for the treatment or prevention of Marburg virus infection. Marburg virus is a highly contagious and deadly virus related to Ebola that causes severe hemorrhagic fever in humans.
      Current treatment for Marburg virus is primarily supportive, including maintaining fluid balance, replacing electrolytes, and treating specific symptoms when they occur. Experimental treatments and vaccines are under investigation, but fenbendazole is not among the known or recommended options.

  317. Karen

    Does this protocol work on ovarian cancer, stage 4? Thanks

    1. fenbendazole

      Hello Karen,
      Fenbendazole is being researched for its potential use in treating various types of cancer, including stage 4 ovarian cancer. It works by disrupting the cancer cells’ ability to grow and multiply, potentially leading to their destruction. Specifically, fenbendazole interferes with microtubule functions crucial for cell division and can inhibit glucose uptake in cancer cells, depriving them of the energy needed to grow.
      However, the effectiveness of fenbendazole as a treatment depends on several factors, including individual response, overall health, the aggressiveness of the disease, the presence of other treatments, and specific characteristics of the cancer.
      Regular monitoring and medical supervision are essential to ensure the best possible outcome.

  318. Marianne Muller

    Does this work for blood cancers as well?

    1. fenbendazole

      Hello Marianne,
      Fenbendazole shows promise in treating various types of cancers, including blood cancers.
      Fenbendazole operates by disrupting the microtubules in cancer cells, which are essential for cell division and growth. Additionally, it can block the uptake of glucose in cancer cells, effectively starving them of the energy they need to survive and proliferate.
      Though there are no specific studies on blood cancers, many of the mechanisms through which fenbendazole works suggest that it could be beneficial for these types of cancers as well. Numerous patients have reported positive outcomes when using fenbendazole for different cancer types.
      If you decide to try fenbendazole, it is important to adhere to the recommended protocol and consistently monitor your progress.

  319. Regina Lauwers

    Should I reduce the amount of Fenbendazole when the stage IV Breast cancer is everywhere in the Body already, Liver included? Or can I stay on the 222mg for each dose?

    1. fenbendazole

      Dear Regina,
      The amount of fenbendazole should not be reduced if you are feeling well, your blood tests are within normal ranges, and your liver enzymes have not increased more than three times their normal levels. Maintaining the prescribed dose of 222 mg per dose is important to ensure the treatment’s effectiveness.
      It is crucial to monitor your health closely, including regular blood tests to check liver function and other important parameters. As long as your liver enzymes remain stable and you are not experiencing adverse effects, you can continue with the current dosage.

  320. Candi

    Would this be ok to do with what the doctor recommended to do or do we have to pick between fenbendazole and doctors recommendation?

    1. fenbendazole

      Hello Candi,
      Using fenbendazole alongside traditional medical recommendations is often practiced and can be safe under certain conditions. Fenbendazole has shown potential benefits in cancer treatment, including its effects on inhibiting tumor growth and enhancing immune responses, which can complement conventional therapies.
      It is important to emphasize that regular monitoring through blood tests and overall health assessments is crucial. This ensures any potential interactions or effects on the body are carefully monitored, allowing adjustments to be made as necessary to optimize treatment outcomes.
      This approach recognizes the importance of integrating different therapeutic strategies to potentially enhance treatment efficacy while prioritizing ongoing health monitoring to ensure safety and efficacy.

  321. Patti

    Fenbendazole is there a weight chart? Like does a 90 on person take 222 mg as well as a 300lb man or is the dosage higher for those that weigh more?

  322. Annette

    My sister was diagnosed with rectal cancer and is exploring treatments. She is a kidney and pancreas transplant recipient (20 years ago and doing well). Is FenBen protocol safe for her? Will it interact with anti-rejection meds or affect her organs? Thank you!!

    1. fenbendazole

      Dear Annette,
      Although fenbendazole is generally considered a safe and well-tolerated drug, caution is advised for your sister given her medical history and the fact that she is taking anti-rejection medications. While it is unlikely that fenbendazole will directly interact with these anti-rejection drugs, careful monitoring is essential.
      Patients using both fenbendazole and anti-rejection medications should be vigilant for any signs of increased side effects or reduced effectiveness of either drug. Regular blood tests to monitor drug levels and organ function are crucial to ensure both the anti-rejection drugs and fenbendazole are working effectively and not causing adverse effects.

  323. GeorgetteHaugen

    I didn’t read about anyone having breast cancer and taking it. I would love to hear.

    1. fenbendazole

      Dear Georgette,
      Fenbendazole is often used to treat different types of cancer, including breast cancer. It impacts cancer cells by disrupting microtubule formation through binding to tubulin, which is essential for cell division. This disruption can inhibit cancer cell proliferation. Additionally, fenbendazole interferes with the uptake of glucose, depriving cancer cells of the energy needed for growth. This disruption can also induce apoptosis, leading to the programmed death of cancer cells.
      For more detailed insights, we recommend reviewing the following case reports. The first report involves a patient with triple-negative breast cancer, which you can read here:
      https://www.fenbendazole.org/triple-negative-breast-cancer/
      The second report details the treatment of an 83-year-old female with metastatic breast cancer, available here:
      https://www.fenbendazole.org/case-report-metastatic-breast-cancer-83-female-2/
      These reports offer valuable information on the use of fenbendazole in breast cancer treatment.

  324. Annemarie Hasemann

    The last 2years I had breast cancer removed, then few months after I had colon cancer, also removed, now I am diagnosed with liver cancer, they give me a few months, My daughter buys fenbendazole for me,do I take it every day a capsule? Or have a break ?I would be grateful for a reply

    1. fenbendazole

      Hello Annemarie,
      Fenbendazole has been shown to inhibit the growth of cancer cells by disrupting microtubule formation, interfering with glucose uptake, and inducing apoptosis. Based on anecdotal evidence and case reports, the usual protocol is to take 222 mg/day six days a week with one day off. This schedule allows the body to rest briefly and can help reduce potential side effects.
      Depending on the condition of your liver, it may be helpful to support liver function with milk thistle. Milk thistle contains silymarin, which has antioxidant, anti-inflammatory, and liver-regenerating properties. A typical dose is 150-200 mg taken one to three times a day, standardized to contain 70-80% silymarin.
      Although there is promising evidence, it is important to note that the use of fenbendazole for cancer treatment must be long-term. It may take 1 to 4 months to notice the first signs of improvement.

    My father currently has stage 4 cancer in his liver. he had a kidney removed in the past because of a single mass that was found in it. The cancer is believed to be related small cell lung cancer. It mentioned people with kidney issues above. His one kidney is working fine. Are there any adverse side effects for someone with one kidney? Also are there any side effects. He had Chemo and hated how he felt. looking for alternative options.

    1. fenbendazole

      Dear Todd,
      Regarding the use of fenbendazole for your father’s stage 4 liver cancer, it is understandable to explore alternative options, especially considering his past experience with chemotherapy. Fenbendazole has shown promise in inhibiting cancer cell growth through various mechanisms and is generally well tolerated with few reported adverse effects. However, given your father’s history of kidney issues and current situation with a single functioning kidney, caution is advised. While fenbendazole is primarily metabolized by the liver and excreted via the kidneys, its impact on renal function in individuals with compromised kidney function is not extensively documented.
      To proceed cautiously, we would recommend starting fenbendazole gradually and monitoring his response closely. It might also be beneficial to supplement with silymarin (milk thistle), known for its liver-protective properties. Silymarin can support liver health and mitigate potential liver strain from medications or cancer treatments. Regular monitoring of blood tests, including kidney function (creatinine) and liver enzymes, is essential to ensure fenbendazole is well tolerated and not causing any adverse effects. This proactive approach will help in adjusting the dosage or treatment plan as needed.

    Would the 222 mg daily protocol with the exception of the one day off be suitable for someone like me? I started out with a stage 4 tumor in my breast. Had a mastectomy done on that breast with several lymph nodes removed, intraductal metastatic breast cancer is what I was diagnosed with and apparently it feeds off estrogen. Fast forward 4 months (no treatment of any kind) and my liver enzymes were very high, did a ct scan on my liver and it showed 2 suspicious areas. Had a liver biopsy done and now the cancer has metastasized into my liver. I have appt to see oncologist early next week but he sent out two prescriptions for estrogen blockers (tons of bad side effects on both) one is for Ibrance and one is for letrozole.
    So I guess my question is, should I start taking the 222 mg fenbendazole protocol daily or because this is in my liver will it not be able to handle it? Thank you so much for any guidance on this.

    1. fenbendazole

      Dear Tami,
      Given your medical history with breast cancer metastasizing to the liver, and considering the potential use of fenbendazole as an alternative treatment, it’s important to approach this with caution and consideration of your liver function.
      Fenbendazole has shown promise in inhibiting cancer cell growth through various mechanisms, and the recommended protocol of 222 mg daily for six days a week with one day off could be considered. However, since your cancer has metastasized to the liver and you have experienced elevated liver enzymes, careful monitoring is crucial.
      Starting fenbendazole gradually and monitoring your response closely is advisable. Regular blood tests to monitor liver enzymes (such as ALT, AST) and kidney function (creatinine) are essential to ensure fenbendazole is well tolerated and not causing any adverse effects on liver function. If liver enzymes show any significant elevation or if you experience any symptoms indicating liver strain, adjustments to the fenbendazole regimen may be necessary.
      Additionally, supplementing with silymarin (milk thistle), known for its liver-protective properties, may be beneficial. Silymarin can support liver health and mitigate potential liver strain from medications or cancer treatments.

  327. Susie

    Does anyone know if this is okay for Liver Cancer?

    1. fenbendazole

      Dear Susie,
      Yes, fenbendazole is considered safe and may be useful in treating a variety of cancers, including liver cancer. There have been promising results and reports of positive outcomes for liver cancer treatment with fenbendazole.
      However, during this protocol, it is very important to regularly monitor your liver enzymes and general well-being. Regular blood tests to check liver function (such as ALT, AST, and bilirubin levels) will help ensure that the treatment is well tolerated and effective for your particular condition.
      You may also consider supplementing with silymarin (milk thistle), which is known for its liver-protective properties. Silymarin may support liver health and help reduce potential liver stress from the treatment.

      I have sarcoma that has metastasized from my left foot, which I had amputated 1yr ago. It is now in my left lung & I have 2 lumps above where they did my below the knee amputation. One in the bend of my leg & a larger one on my inner thigh. I am currently on chemo again. I had hepatitis on 1978. They do not know what kind. What fenbend protocol (frequency) should I follow? Not sure what you’re asking for the website?

      Hi my mother inlaw got cancer 2 years ago on her kidney and they had to remove her right kidney. Unfortunately it’s back in her left kidney, brain,lungs, bones. It is stage 4. She is on dialysis for her kidney because it has stopped functioning and they are trying to save it. Will fenbendsloze be safe for her to take with kidney issues???

      1. fenbendazole

        Hello Kristie,
        I’m sorry to hear about your mother-in-law’s condition. When considering fenbendazole, particularly in complex health situations like hers, it’s important to proceed with extreme caution. Given that she is on dialysis due to kidney failure, adding any medication, especially one not typically used in human medicine, carries significant risks.
        Due to the experimental nature of fenbendazole for cancer treatment and the lack of clinical data regarding its use in patients with severe renal impairment, using this medication without explicit approval and careful supervision from her healthcare team would be considered unsafe.

    My husband has MDS and they want to do Chemo and a bone marrow transplant! It has not turned into leukemia yet but it will. They said 1 year if he does nothing. Will this work on the bone marrow leukemia?

  331. Cindy S

    I just learned about this website from a friend who had great results using this and its protocol in the treatment of prostate cancer advanced to bone cancer. He is cancer free now… Keeping track of this website for possible future use…

  332. Terry

    what would be the cost in bulk? there are different prices from each company ..whats a normal price to pay? where i will know i’m not paying to much ..i’m looking for a couple lbs

    1. Fenbendazole.org

      Dear Terry,
      thank you for your question. As far as we know, there aren’t many vendors who supply trustworthy powder in bulk. A pound usually costs about $400. That is the lowest price we could find on the internet, such a product is offered by Fenbenlab.

  333. Carrie

    I cured my dog! Matt cell tumor. Have her daily 222 mg fenben, curcumin, coconut oil, turkey tail and reishi mushroom. Had tumor removed after 2 months of this treatment. Tumor had shrunk to 1/3 of it’s original size. Veterinarian said it was covered in a white web of some sort and he didn’t recognize the tumor. He wasn’t familiar with the treatment that I was using so he was really surprised at what he found inside. The tumor came right out! Veterinarian had me send it to the college to get it tested because even though they identify needle aspiration on it and identified it to begin with they thought they were wrong because it didn’t look like a mast cell tumor. I’ll tell you why. Because it was dying and they’re not used to seeing a dying mast cell tumor! Sure wish those veterinarians would have listened to me but they’re not open to hearing about fenbendazole. Even with the proof right in front of them. So I’m just here to share that with you because I love my dog Daisy so much… And fenbendazole saved her life! I believe that with every bit of mine soul. In this polluted world we live in, with all the chemicals and nasty stuff all around us all the time. There’s Hope. I know for sure it’s 100% for sure that this cured my dog of a cancer that would have killed her. I’m so grateful for this website. God bless everyone reading this I’m just please please please….. take the medicine!

      Dear Carrie, omg. I was excited to read your comments. The light and love of my life Ruby (doggy) has lymphoma. She has enlarged lymph nodes all over her body now. We have been trying all sorts of things but to no avail. I am ordering this today in the desperate hope this may save her. Can I ask if you gave her fenbenazole 3 days on/4 days off or did you go for gold and go 7 days a week? Best regards Stephanie, New Zealand

  334. william mckenzie

    my dad had lung and brain cancer back in 1982.he went through the chemo and radiation he died a year and a half later.i am no doctor but the treatment seemed harder on him than the disease.here it is 40 years later and chemo and radiation are still being used.i started having prostate issues some blood and urinating issues.my psa went from 4 to 5 in 8 months.my doctor actually set me up with this treatment because my medical insurance through work has a high deducible.she isnt 100 percent sure i have cancer yet.however my older brother had prostate cancer and cancer is in the gene pool.so i will do this and i am scheduled for another psa test in February.thank you sharing this information.

    1. Elizabeth Trevino

      Pls let me know how your next testing goes! My husband has prostate cancer and he is on feben and he recently went in for a PSA check and they say all is good! But we don’t have the pill we found fenben in dog wormer!

    2. Veronica

      William, if you remember to update us, we would love to hear how your scans go in February 2023.

      Sounds like you have a compassionate, smart, out-of-the-box-thinker of a doctor. She’s a keeper!

      Please see comment below where Carrie mentions the mushrooms she also gave to kill her dog’s MAST Cell Tumor. I wonder if those would also help you.

    I know of two people with the,” you have a few months to live” diagnosis that took fenbendazole 222mg capsule, 3 days a week. They both, one with throat cancer and one with lung cancer are now cancer free and still alive. Never give up. You can be healed from cancer.

    1. Sky

      Hi Susan, I’ve just found out Fenbendazole.
      A. Did they just take Fenbendazole 222mg capsule, 3 days a week alone without any other supplement?
      B. How long did they take Fenbendazole?
      Thanks!

    How long does fendbendazole take to start working and show improvement?

    How long should I take it?

    I find articles of reviews to take high doses for 10 days then do the 3 on and 4 off routine. So what are people saying or what are the real reviews?

    1. fenbendazole

      Dear Shelby,
      Generally, fenbendazole is a long-acting drug, and it may take between 1 to 4 months to see improvement. The time required to observe results can depend on various factors such as the type and stage of cancer, the individual’s overall health, and how their body responds to the treatment.
      Fenbendazole is often used for extended periods, sometimes for several years or longer, until the disease is completely gone. Even after achieving remission, some people continue to use it prophylactically to prevent recurrence.
      Regarding the protocol, people often use different schedules, such as taking high doses for 10 days followed by a 3 days on, 4 days off routine. However, since fenbendazole is used off-label, individuals tend to experiment with doses and schedules on their own, which can be risky.
      We recommend using our dose calculator to help determine the right dose and schedule tailored to your needs. The calculator is calibrated to achieve the best results with the least risk, based on available data and user feedback.
      Please feel free to reach out if you have any further questions or need additional information.

      Dear David, that is wonderful to hear! It’s always encouraging when test results show improvement! Keep up the positive momentum. We celebrate these victories along your journey to better health!

  339. Paula

    Is it possible to take 10 times this amount for a rare, aggressive cancer?

    1. fenbendazole

      Thank you for a comment! We would not suggest taking 10 times the amount. Such big doses can disturb liver cell homeostasis and disturb enzymes like Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST). Taking huge doses for prolonged periods of time could potentially lead to liver damage or inflammation. We suggest to stick to a normal protocol. It will be equally effective and won’t risk harming your liver, potentially requiring you to stop taking fenbendazole altogether.

  340. Deborah Lindquist

    So thankful to have found hope. My cancer metastasized. Chemo did that. I am giving this protocol a try. Thank you so much for giving hope where there was none. Positive attitude in the making. God bless these cancer warriors. Each and every one. Thank you Joe Tippens❤️

    1. Marsha

      Today I received my order. Thank you.
      I have been told that cancer killed my husband, but he told me to tell everyone that chemo killed him. He had metastasized cancer that started as a small spot on the top of his head. He had surgery to remove that and then radiation. He said that is what baked it into the rest of his body. They removed his ear and half his face. Evevtually after so much more radiation and chemo it went to his lungs. He basically starved to death.
      Last week I was told I need chemo for a form of blood cancer.. I am taking your protachol instead.

      1. Caroline Poole

        Hi Marsha, I am new to this post and to this topic. Just heard about Fenbendazole this evening. I am horrified by your story and wish I could offer more than some kind of moral support. Your brand of courage is rare; I would very much like to know how you’re doing in this battle. My very best wishes, Marsha. Beat the hell outta this thing.

        1. Ray Pafford

          I weigh 250 lbs but why dies the dosage up up so high to 444mg, 6 days a week ? That’s 4 times the regular dose.

          1. fenbendazole

            Hello Ray,
            Based on your weight, you need a daily dose of 444 mg of Fenbendazole. You should take this amount each day for 6 days, followed by one day off. This dosage is carefully calibrated to be effective while minimizing harm to your body. It is appropriate for your weight, but if you have concerns, you can start with a lower dose and gradually increase it. Additionally, regularly check blood tests and monitor your well-being to ensure the treatment is proceeding smoothly.

      2. Tara

        How are you Marsha? I hope the protocol is working for you. May God bless you. I will pray for you.

      3. George Wynns

        Good for you, Marsha! Sorry about your husband.

        Hi Marsha
        I was diagnosed with multiple myeloma in January this year. My treatments have been going well and I’m really close to remission but they want me to do this stem cells transplant that’s very very risky and dangerous.
        Do you have the same blood cancer?

        My 75 year old brother was hospitalized for extreme pain. After 4 biopsies they gave him a bag of morphine and sent him home to die with stage 4 pancreatic cancer. I started praying for Yahuah Elohai to please send him help! He was too far away and living alone. The next day a friend came to his house with dog wormer (Fenbendazole) and cbd oil. He started using it March 23 and today, Nov 23 he is going strong and helping his pastor plant another church. Halleluyah! Thanks for this info! My husband, my sister and I are now using it as a preventative. We have also added DMSO and MMS to the cleanding.

    1. Christine Blubaugh

      Can this be used for a child age 2 that was recently diagnosed with B-ALL leukemia.. ? And should it be in conjunction with the chemo protocol they have for pediatric patients or can it be used alone. Her spleen is enlarged , and she required two platelet transfusions and a blood transfusion before chemo was started to have a hemoglobin that was 7 move to 12 and the platelets were 34,000 then went to 63,000. Thank you for your help

      1. fenbendazole

        Dear Christine,
        Fenbendazole is explored for its potential to treat various cancers, including B-ALL leukemia. However, given your child’s age, using it could be particularly risky. We advise against using Fenbendazole for young children, especially those who are already undergoing the intense stress of chemotherapy and experiencing low blood counts.

  343. Michele Thomas

    Can you take all this as precaution

    1. fenbendazole

      Dear Michele, yes you can take fenbendazole for prophylactic purpose. And we do have a dosage guide that is for it.

      Preventing cancer relapse – prophylactic protocol
      Fenbendazole 222 mg. Take 1 capsule three times a week, once a day after a fatty meal. Then take no fenbendazole for four days. Repeat this cycle every week.
      Bio-Available Curcumin 600 mg. Take 1 capsule two times a day after breakfast and lunch with no pauses.
      CBD oil 25 mg. Take 1-2 drops (total ~25 mg) under the tongue every day before sleep.
      Tumor marker regular checks every couple of months, regular yearly cancer imaging tests. If there is no cancer relapse after 5 years, decrease the frequency of tests.

      Preventing cancer for someone who was always cancer-free – prophylactic protocol.
      Fenbendazole 222 mg. Take 1 capsule three times a week, once a day after a fatty meal. Then take no fenbendazole for four days. Repeat this for 10 weeks. Stop for 10 weeks. Then repeat the cycle again.

    Do I need a prescription from my vet! Lol!
    Direct shipment information from the source you trust please. Or do I go to the local feed store? I’ve used it on my dog the kind with a horse on the box. Same?

  357. Jack Hobson-Dupont

    Each dose of Panacur® is 1 gram, of which 222 mg. is actually fenbendazole. The rest is inactive ingredients/filler.

    Fenbendazole is sold throughout the world to treat livestock, farm animals, captive animals, pets, etc. Typically, the fenbendazole is provided to manufacturers by a chemical company and is then packaged as a commercial product. One package of pharmaceutical grade 99% pure fenbendazole can be purchased from a amazon or internet, it typically includes shipping to the U.S.

  358. David W. Edwards

    You suggest that some side effects may occur in patients with kidney disease. What is the recommended protocol for someone with kidney disease — with creatinine at 3.5? Urine flow is excellent in this patient.

    1. Fenbendazole.org

      Dear David,
      thank you for your question. Well, kidney disease for one person is not the same for the second person. First stage kidney disease is not the same as stage five kidney disease. We recommend that people with stage 5 renal disease restrict their fenbendazole intake to 111~150 mg per day. Patients with less severe renal failure may continue to take fenbendazole as normal.

      1. Becky

        Just wondering how long people started feeling better after taking fenben

        1. fenbendazole

          Hello Becky,
          The time it takes for individuals to experience improvement after starting fenbendazole treatment varies due to several factors. These include the type and stage of cancer, the individual’s overall health and immune function, genetic factors influencing drug metabolism, the specific dosage and treatment regimen used, and any concurrent therapies being administered.
          Typically, fenbendazole is administered over an extended period, often several months. Patients commonly begin to notice results within 1 to 4 months of consistent use. However, responses can be highly individualized, with some individuals experiencing benefits earlier or later than others.

    On the Vitamin E what was the one that had 2 things inside of this for it to work properly I the bought 400 one from Holland Barrett brand in the UK should I buy another one instead? thanks so much

    1. Fenbendazole.org

      Dear, Aidan.

      The current protocol does not need Vitamin E to be effective in cancer treatment. We were unable to choose a single brand as the finest. What matters is that the Vitamin E capsules have the required amount of the vitamin. Nonetheless, Vitamin E is not necessary or advised in the updated protocol since it has no measurable effect for treating tumors.

    2. AL

      Hi Aidan –

      I do know that Clif High says you must also take vitamin E with tocotrienols in it. There are many forms of vitamin E. This one activates the fenben. Not sure myself just passing this on.

      Thanks so much…. And thank God for a friend of mine that shared this information regarding the Fenbendazole….
      I will be ordering it later today for the first time ….I have metastasized ovarian cancer and mild kidney disease now due to a tumor blocking my urinary tract that the doctors have put a stent in to keep it flowing…. I was wondering if this is OK to do the regimen suggested…thank you Nina

  360. Goerge Garcia

    Hi, are there any new revisions to the original protocols. Thank you

    1. Fenbendazole.org

      Dear George,

      yes. We kept the original protocol, which is the lighter one and has you take fenbendazole less often. It works best for people who don’t have advanced illness and metastasized tumors. It’s also a good choice if the tumor hasn’t grown too much.
      In the new version of the protocol, fenbendazole is taken every day without any breaks. However, we believe that skipping fenbendazole every Sunday is good because it gives the liver a chance to rest. Finally, there are the preventive regimens. One is for those who have had cancer in the past but are now NED and want to stay that way. The second is for people who have never had cancer but have a family history of cancer or other significant risks. This population may take fenbendazole to avoid developing cancer.

    2. Diana Slo e

      I had cancer on my tongue which was cut out along with lymph on that side of .y neck. Will this treatment benefit me by preventing recurrence or it showing up elsewhere in my body?

      1. fenbendazole

        Hello Diana,
        Yes, fenbendazole can be used as a preventative measure against cancer recurrence or spreading. It works by disrupting the formation of microtubules, essential components of a cell’s structure necessary for cell division. By interfering with microtubules, fenbendazole inhibits the proliferation of cancer cells, preventing them from dividing properly.
        Additionally, fenbendazole has been shown to induce apoptosis in cancer cells, helping to eliminate them. It can also interfere with glucose uptake and metabolism in cancer cells, leading to energy depletion and cell death. Some research suggests that fenbendazole can inhibit tumor growth by targeting cancer stem cells, which are believed to be responsible for tumor formation and recurrence.
        Furthermore, fenbendazole can inhibit angiogenesis, thereby starving tumors of the necessary blood supply.
        To find the right dosage and schedule, we recommend using our dosage calculator. Be sure to select “Cancer prevention protocol” in the “Protocol” section to get accurate recommendations.

    What do you consider a “fatty meal” if we are whole food plant based with limited oil low salt and no sugar? Maybe salad dressing with olive oil and or sometimes we have can of sardines in olive oil. Or would avocado or nuts be considered fatty enough?

    1. Fenbendazole.org

      Dear Kathy,
      that’s a great question. You may eat anything you like since it slows down the motility of the intestines and gives fenbendazole more time to enter the circulation. To achieve the most, you can mix fenben with olive oil, fish, avocado, nuts, yogurt, a sandwich, or a peanut butter sandwich.

      1. Judith

        Yes I have hepatic cellular carcinoma of the liver, so is it safe for me to take fenbendazole, , and what doses should I take. Thank you!

        1. fenbendazole

          Hello Judith,
          Generally, the use of Fenbendazole does not cause any side effects. However, depending on the nature of your illness, we advise closely monitoring your overall condition and checking your liver enzymes every few months. Regular blood tests are also recommended to ensure the treatment is proceeding smoothly.
          To support liver function, we suggest adding Milk Thistle to your regimen.

  362. Mel

    Fenbendazole 222 mg. Take 1 capsule three times a week after a fatty meal

    If it comes in grams, what’s the dosage to capsule? If I have the 1pound jar, how do I measure a capsule?

    1. Fenbendazole.org

      Dear Mel, we assume you have pure fenbendazole powder and are having trouble figuring out how to measure a single dose. You should get a digital pocket scale and a spoon that will make it easy to measure about 222 mg of fenbendazole each time. Some fenben suppliers will even provide a clean 200~222 mg spoon with your purchase of their powder so you can easily measure each dosage.

      1. Laura Berry

        I weigh 230lb should I stick to the 222mg recommended dose or use the 444mg instead?

      2. Gloria

        Hi! Thanks for sharing all you do. I have a question about the absorption. My little brother was rushed in for emergency surgery yesterday. They removed a portion of colon. Now has permanent colostomy. He has done so well the last 3 yrs between treatments and radiation. Nodules now seen liver and lungs. Oncologist came in today said no more options and discharging him on hospice with a 3 month prognosis. He is 40 😪 He doesn’t even feel sick with the exception of the bowel issue. Im wondering with the surgery he had if it will affect how his body would absorb the fen ben. I understand what’s been said about watching his liver. We’re aware about that. Thanks for any input, guidance or thoughts you can provide. From all the information shared and personal stories that are shared on platforms like this brings a glimmer of hope in times of complete darkness. I thank you!!! Much love to all who are going through this or watching their loved one going through it🧡

        1. fenbendazole

          Hello Gloria,
          Given your brother situation, it is understandable to be concerned about how past surgeries and current medical conditions may affect the absorption and effectiveness of fenbendazole.
          Fenbendazole is primarily absorbed in the gut, so any significant gastrointestinal changes or surgery can impact its absorption. Since he had part of his colon removed and now has a permanent colostomy, it is possible that this could affect fenbendazole absorption. However, absorption issues are generally more significant when large portions of the small intestine are involved, as this is where most nutrients and drugs are absorbed. Given that fenbendazole is mainly absorbed in the small intestine, and if the surgery was only in the large intestine, the impact on absorption may be less significant.
          Considering nodules are seen in the liver, it is crucial to factor in liver function when using any drug, including fenbendazole, as the liver plays a significant role in drug metabolism and clearance.
          Regular blood tests and health monitoring are essential to assess how his body is responding to fenbendazole and to check for any potential side effects or interactions.

      3. Ronald van leeuwen

        I bought the 444mg..
        How should I take it,and how long?
        I just want to take it to get rid of possible parasites..
        Smoker for 35 years,so I don’t know that.

        1. fenbendazole

          Hello Ronald,
          We recommend using our dosage calculator to determine the exact dosage of Fenbendazole you need based on your body weight, as well as the appropriate consumption schedule for parasite cleansing. Without knowing your weight, we can not provide a precise dosage, but the typical protocol for parasite cleansing involves taking Fenbendazole once a day for 5 consecutive days. This treatment may need to be repeated after three weeks.
          For precise dosing and scheduling, please refer to our dose calculator available at the following link:

  363. Fred Weber

    Has anyone used Safe-Guard Fenbendazole liquid dewormer for goats? The liquid in suspension yields 100 mg / ml. Tastes a little chalky but is easier to swallow than the powdered version for dogs. I have noticed no ill effects taking half teaspoon (2.5ml) per day (7 days a week) along with vitamin E (Solaray Bio E Gamma Plex), Solgar Full Spectrum Curcumin, and CBD oil. I am fighting a recurrence of very aggressive prostate cancer.

    1. Fenbendazole.org

      Dear Fred, you can pour too much fenbendazole into one dose of the Safe-Guard liquid dewormer, which makes it hard to figure out how much to use. We suggest trying to get the powdered version (Panacur) or trying fenbendazole in capsules or tablets.

      1. Marta Jimenez

        My vet prescribed Fenbendazole for my 78 pound dog. How should I adjust the dosage for her?

      2. Allie

        The dosage for parasites is 222mg (1gram of panacur) in 155 pound human but much higher in dogs…4 grams for. 40 pound dog I’m confused by what to take

    2. Bea

      Yes I’ve been using the Fen. for Goats liquid, it’s the same thing as used for dogs, horses, etc. As for dosage I’m not going to say different than what has been said but as for the act of dosing I purchased the small bag of oral push syringes [no needles just straight thru] so i can easily pull and exact dose using the syringe. Note: Amazon keywords ’10 Pack of 10ml 10cc 2 Tsp. Oral Medication Syringes’

      This is the SUPERIOR manner to handle the liquids and I just wash and reuse the syringes, this is a non-toxic drug. Everyone is very different, but I don’t exaggerate to say that the first week that I started dosing, first with powders. The pain in my turmor areas decreased noticeably and hardly believed it but the bulk of my background baseline pain in my back almost totally disappeared and I did not expect that on week one.

      Needless to say I’m still on the Fen. Train and don’t plan on getting off until my day has come. I am very very enthused two months into my journey. I only have one thing to add about dosing that I have not read a single comment on, not once in all the sources I’ve read. I am a large person, the good thing is I’m not very large from obesity, I’m just a very big person and all the dosing I’ve read makes not comment or explanation as to whether the dosing stated for ‘everyone’ is relevant when a person like me is in the mid 220 lbs. Face it, my lymph sys., liver, blood, muscular system, etc is bigger than the average person so I do make my own adjustment but I don’t want to share because i have no knowledge as to the veracity of my dosage

    3. Beatriz

      Fred if you are still out there please tell if the protocol has been successful or not for prostate cancer. and yes the liquid works just as well just make sure you take the time do calculate your liquid in ml compared to 228 grams of pure per day powder/capsule. I started 43 months ago with the canine packets Pancur and then I switched to the liquid goat dewormer product for two full months until just recently when I got my bulk order in from the laboratory. I bought enough for two full years of treatment since I live in the Oceana Region and delivery can be problematic on short notice.

    4. Beth

      Hi is fenbendazole treats also liver cancer pls answer and how do it takes is it 1capsule a,day

      1. fenbendazole

        Dear Beth,
        Yes, Fenbendazole can be effective in treating liver cancer. However, because Fenbendazole is metabolized in the liver, and the liver of a patient with liver cancer may not function as well as a healthy liver, caution should be exercised. We recommend regular blood tests and frequent monitoring of your health and liver enzyme levels while taking Fenbendazole.
        For dosage and scheduling, we suggest using our dosage calculator, which will determine the best schedule and dose for you. Fenbendazole should be taken once a day after or during a meal.
        You can find the dose calculator here: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/

  364. Dave

    For the original version of the cancer treatment. How long would one stay on this protocol and continue taking this medication to fight cancer?
    2 months or 6 months or ?

    1. Fenbendazole.org

      Mr. Dave, Thank you for your insightful question. It totally depends on how you respond to it. Some individuals only experience the first results after 2 months, therefore stopping fenbendazole right away would be a bad idea. Your best option would be to take fenbendazole on a continuous basis while also monitoring tumor sizes with PSA or CEA blood tests or imaging every 3 to 6 months with a CT scan or ultrasound. After the tumors shrink or disappear, many people continue to take fenbendazole for an indefinite amount of time in order to keep the cancer at bay. Unfortunately, the therapy does not finish after the tumors are removed. They often regrow and should so be treated whenever feasible.

  365. Teresa B.

    Has Fenben ever been used for non-melonoma skin cancers? Can it be used topically and orally at the same time for skin cancers?

    1. Fenbendazole.org

      Dear Teresa,
      glad you asked that. Yes, fenbendazole can be taken by mouth and put on the skin at the same time to make the anti-cancer effect even stronger. Taking it orally is strong enough, though. Fenbendazole has been used to treat non-melanoma skin cancers, like squamous cell carcinoma and basal cell carcinoma. It does have an effect, but if the cancer hasn’t spread yet, you should have a dermatologist look at it. They might be able to give you a quick, local treatment to get rid of it.

          Hello, thank you for your question about the use of fenbendazole for kidney cancer.
          Yes, there have been positive testimonies regarding the use of fenbendazole in treating kidney cancer. You can read about one such case of a patient with renal cell carcinoma who experienced significant improvements here: https://www.fenbendazole.org/renal-cell-carcinoma/
          Many patients have reported encouraging results when using fenbendazole as part of their treatment regimen.

      I took 222mg capsule once a day 3 days a week. I had Basel cell carcinoma. After a few weeks, the spot swelled slightly then drained a clear liquid, then healed and disappeared. I did follow up with the dermatologist. Only a small scar that can not be seen without a magnifier remains. I have a very large scar from when they cut off the first one. It has been over a year. I am still cancer free.

      1. Lori

        Hi Susan,
        Interested in Your protocol for treating skin cancers, How much and how many days did you takeache pills orally? I have been struggling with squamous and want to try with fenben.

      2. Donna K

        Exactly how many weeks did it take to see an improvement of the spot? I am considering superficial radiation therapy to treat my basal cell skin cancer. I have been on fenben 1 week. I would like to hold off on radiation until I see if fenben helps. When can I expect to notice it working? This would help me decide to wait with radiation.

      3. Pam

        I appreciate your comment. I had one cut out on my face in 2011. It is now coming back. I’m starting the protocol. No more cutting.

  366. Pat Webb

    is it true that your protocol is now 7 days a week ? and 222 mg per day ?

    I have just been told I have lung cancer via my Oncologist, being a senior on a fixed income, seeing all my friends pass away from cancer.. my oncologist said without treatment I had 5 yrs… I would be close to 75 yrs old by then and I am good with that. I’m not going to rush it, but I will be okay when my number is up! (so to speak) I was wondering if you know of any Studies going on in my area , (southern) North Carolina I did a Study in 2009/2010 For Hep C, and they have a cure now. So I am up for it. My email is [email protected]. Thank You for your time.

    I use the liquid and mix it with fruit juice…..I did this everyday along with the rest of the instructions. I was diagnosed in early 17 as my PSA # was16. I brought it down to 11 and it stated there for these last 4 years. BUT I ran out of the liquid fenbendazole 6/8 months ago and a test last week put my PSA at18. I’m no doctor but I did order another liter last night…..the plan is to knock back down…at least under 16 as it was in 2017.

    1. Lorne Droneck

      I as well had elevated PSA, 16,now down to 7,only bin taking Fenben for 2 weeks, prostate size 63cc,normal should be 30cc,haven’t done second ultra sound yet

  368. Gretchen

    Are these dosages per day or per capsule? For instance does one take a Vit. E 800 I/U capsule after every meal or does one take enough 200 and 400 I/U capsules to total 800 for the day? Same with Curcumin- is it two 600 mg per day or 600 mg total split into two 300 mg capsules? Thank you for clarifying.

    1. Fenbendazole.org

      Dear Gretchen,
      thanks for asking such a good question. All of these amounts are for one day. The supplements are taken every day, without breaks (in contrast to fenbendazole, which is taken with periodic weekly breaks).  Depending on what you can get your hands on, you can split the dose in half if that works better for you. You should take 800 I/U of vitamin E and 600 mg of curcumin each day, and this can be taken in parts.

      1. Buck A

        I’ve looked above and don’t see the reference to vitamin E. Did I miss something? Thanks so much.

        I am just getting ready to start Fenben. Prostate cancer reoccurrence after a radical prostatectomy in Nov 2021. PSA dropped to .02 post surgery but started to creep up last June. PSA is still very low at only .2, but it’s moving up. They want me to endure chemical castration with a Lupron like daily pill for 4 months and then 35 sessions of radiation. Not my cup of tea after reviewing all the side effects!! I’ve seen a number of the success stories, like Joe’s. I just received my Fenben today and I hope I can knock my PSA down to where we can do watchful waiting. Any success stories on Prostate Cancer?

        1. fenbendazole

          Dear Buck,
          Thank you for your question. Vitamin E is indeed a powerful antioxidant, but it also has blood-thinning properties. Given that cancer is more common in older individuals, many of whom are already taking blood thinners, adding vitamin E to the protocol could potentially increase the risk of excessive bleeding. For this reason, vitamin E has been removed from the protocol for safety reasons.
          The current protocol does not require vitamin E to be effective in treating cancer. Research has shown that vitamin E does not have a measurable impact on tumor treatment when used with fenbendazole. While some studies suggest that vitamin E might enhance the effectiveness of fenbendazole, these studies are limited and inconclusive. If you decide to take vitamin E, please be aware of its blood-thinning properties and ensure that you regularly monitor your health through blood tests.
          Regarding your prostate cancer, we understand your concerns about chemical castration and radiation therapy. There have been success stories of patients using fenbendazole to manage and reduce their PSA levels. While individual results can vary, many patients have reported positive outcomes using fenbendazole for prostate cancer.

          1. Chris

            Where to get fenbendazole?

          2. Fenbendazole.org

            We are not affiliated with any fenbendazole distribution company, so we do not share any company names. However, we suggest taking the time to look at product reviews from verified customers, such as trustpilot, scam adviser or similar. Nowadays, even social networks are teeming with people interested in sales, so it is better to look for companies with the most real customer reviews that have at least their own official website.

      I know this is from 2020…. what a nightmare of a year! Anyway, I wondered how your husband made out. God bless.

  369. Melissa

    Good morning Joe. I just ran across your protocol and I am very interested in it. My husband was diagnosed with stage 4 small cell cancer last December. He has done chemo iv, been on immunology and now on Termadar, which he is doing three weeks on and one off and we go back to get scans again in a month. He has done so very good on all of his chemo, had very little effects, but now seems to be slowing down and his back is hurting him more. Anyhow, I was wandering if you had any further help, if you would please send me the information?
    My email for home is [email protected].
    Thank you so much for sharing this with everyone and giving them a second chance. It is so wrong of the doctors that have had information on this but never shared. There are so many individuals that have cancer and could benefit from it, and all because someone doesn’t want their money source to come to a holt.

    Thank You again!

    1. Gee

      Hi 👋 Don’t know if you still follow this thread. If so did your husband use the protocol.
