    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

      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.

    Thanks for your reply regarding my dog and Fenbendazole, great information.
    What happen to the Supplier Tab? Listing high quality, good and safe suppliers is really appreciated. I thought I saw that Tab before, now its gone or I can’t now find ………. Thanks

    1. fenbendazole

      Dear Ted,
      We regret to inform you that the “Suppliers” section is temporarily unavailable due to technical difficulties. We apologize for any inconvenience this may cause and are working diligently to resolve the issue as soon as possible.
      In the meantime, we recommend visiting Amazon, where you can find a variety of Fenbendazole suppliers and select the one that best suits your needs.

    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.

  5. 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.

    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.

  7. 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.

  8. 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!

    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.

  9. 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.

  10. 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.

  11. 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.

    Sziasztok. 69 éves vagyok. Végeztettem PSA vizsgálatot kétszer. Az eredmény magas volt. Először 4,5 másodszor 5,5. Az fpsa 18. Kérdezném, melyik protokolt javasolja, és esetleg mit tanácsol. Előre is köszönöm.

    1. fenbendazole

      Hello Ferenc,
      Fenbendazole can be highly effective in treating prostate cancer. To determine the appropriate dose and administration schedule, we recommend using our dose calculator. This tool will help you find the best dose and schedule for your specific situation.
      You can access the dose calculator by clicking on this link:
      Additionally, it is important to regularly check blood tests and liver enzymes. We also suggest conducting monthly PSA tests during treatment, which can provide timely information about the body’s response to fenbendazole. Frequent monitoring helps detect any rapid changes or trends.

  13. 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:
      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.

  14. Nameera

    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.

  15. 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,

    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/

  16. 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,

    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.

  17. Andrey

    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.

  21. 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.

  22. Christina

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

  23. Alexandra

    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.

  24. 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.

  25. 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.

    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.

  28. 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.

    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:
      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.

    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.

    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.

  32. 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.

  33. 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:
      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.

  34. 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?

    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.

  35. Max

    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.

  36. 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.

  37. 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.

  38. 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.

  39. Virgulino


    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.

  40. 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!!

  41. Michelle

    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.

  42. 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.

  43. 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?

    Hi Stephanie,

    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.

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


  46. 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.

  47. 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.

  48. Hugo

    have I got to take 444mg daily for parasites if I am a 120 kg person ?

  49. Margaret Midkiff

    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.

  50. Tyler

    Curious if this will help with Multiple Myeloma.

    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.

  51. 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.

  53. 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!

  54. 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.

  55. 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.

    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.

  61. 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.

  62. 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.

  63. Tom

    I just purchased 100G of Fenbendazole powder. It’s 99 % pure. What dosage is recommended for patients with cancer? The animal dewormer is only 22% Fenbendazole.

  64. 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.

    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.

      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/

    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.

    I have the same question as Kathy Brink above. My MDS has been identified as “low risk”. Will the Fenben protocol help eradicate this? Thanks!

    1. fenbendazole

      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.

      Hello Tracy,
      Fenbendazole frequently demonstrating compatibility with various medications, supplements, and conventional cancer treatments, including chemotherapy, immunotherapy, and radiotherapy. However, it is recommended to discontinue fenbendazole use a few days before, during, and after chemotherapy sessions. Additionally, it is crucial to closely monitor the patient’s overall health and conduct regular blood tests to verify that the treatment is both safe and effective.

  75. Tom

    Thank you so much for this great website with all this detailed information. Many blessings.

  76. 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.

  77. 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.”

  78. 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,


    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.

  79. 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.

  80. 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.

  81. 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.

  82. 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.

    Hi I had a full leg body scan and it shows that I have cancer everywhere what are my best options. I need help with the right dose big please I want to do it right* God bless you for sharing this info.

    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.

    My dog which is a Black lab has a massive cyst on her neck two sizes of a grapefruit the Vet says it’s up to me weather to take it out or not she’s at risk because her throat my close up and not reopen do to a disease some dogs get and she’s 12yrs old he suggests not doing anything until it bothers her. 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.

  87. 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.

  89. 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.

  90. Peggy

    Hello, Can I take this protocol with targeted therapy drugs for lung cancer? I am taking Afatinib

    1. fenbendazole

      Hello Peggy,
      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.

  91. Mary Jo

    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.

  94. 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.

      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.

    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.

    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.

    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.

  102. Alex

    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.

    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.

  104. 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.

  105. Lane

    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.

  107. Wilfried

    Hello Friends,

    I am confused by the dosage of Fenbendazole. The calculator on this site says:
    92kg = 444mg

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

    Regards from Germany

    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.

  108. 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.

    Hello- I have a epenymoma brain tumor. I am taking the granuel form in the safe-guard packet,[2grams] twice a day.Do not know long to keep taking it? Also a bit cofused about taking it before a meal or with a meal ? Thanks Tracy

    1. fenbendazole

      Dear Tracy,
      If your body weight requires a daily dose of 444 mg of Fenbendazole, you have selected the correct amount with the Safe-Guard packets. We recommend taking the entire dose at once with or after food to enhance absorption. For more detailed information on dosage and usage guidelines, please visit the following link:

  112. Stephanie

    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.

  113. 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.

  115. 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.

  116. Mary

    Can you really not use this on someone who is 22 pounds? Why not just lessen the dose?

    1. fenbendazole

      Dear Mary,
      Administering any off-label medication to a child weighing 22 lbs is highly risky and unsafe. We strongly advise against attempting to treat a baby of this weight on your own. Our dosage calculator is designed with safety in mind and includes age and weight restrictions to prevent harm.
      For pets, Fenbendazole can be prescribed to animals of this weight.
      To determine the correct dosage, choose “Animal” under “Protocol for” and then select the appropriate species for your pet.

  117. David W W

    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.

  118. 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.

  119. Dragos

    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

  121. 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.

  122. 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.

  123. Brigitte

    I am wondering why a 100 lb. dog requires 11 times the amount as myself and 5 consecutive days instead of 3.

    1. fenbendazole

      Dear Brigitte, thank you for the wonderful question.
      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.

  124. Vivian

    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.

  125. 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:

    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:
      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.

  128. 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.

  129. 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.

    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.

    Hello, my grandmother was just diagnosed with pancreatic cancer. In 2007 she had her left kidney removed due to cancer. Can I start her on fenbendazole, if so how many mg?

    1. fenbendazole

      Dear Cynthia,
      Fenbendazole should be used cautiously, considering your grandmother’s medical history and current condition. It is crucial to evaluate how her body will process the medication and any potential impact on her remaining kidney.
      To determine the appropriate dosage and schedule, please use our dosage calculator available at this link: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
      Ensure that your grandmother’s health is closely monitored for any side effects or interactions with her existing medications. If she begins taking fenbendazole, regular blood tests and check-ups are essential to ensure safety and track the treatment’s effectiveness.


    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.

    What is recommended protocol for this?

  134. 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.

  136. 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.

    I had bladder cancer for the last year and a half fighting with bcg treatments finally I found out about Fenbendazole I take one 222mg capsule a day along with berberine,curcumin,quercetin vitamins twice a day vitamin d 10000 iu a day and vitamin e 1 a day then cbd oil half gram a day and most important is stick to an alkaline diet many foods are acidic which feeds cancer I got checked after 2 1/2 months CANCER FREE this worked for me but many testimonies at Fenbendazole for cancer online talk about CURING ALL KINDS OF CANCER one man had 4th stage cancer cured within 5 months even though I got a cancer free diagnoises I still take a maintanance set of half the vitamins and 3 Fenbendazole a week

  138. W.J.H.

    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

      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.

  139. 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/

  140. Mily

    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.

  142. 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.

  143. 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:
      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.

  144. 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.

  145. Bernie Morrell

    Is taken the 444mg to much to take for a 240 pound man thanks.

  146. 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.

  147. 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.

  148. 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.

  149. 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.

  150. 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.

  151. 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?

  152. 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.

  153. 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:
      The second report details the treatment of an 83-year-old female with metastatic breast cancer, available here:
      These reports offer valuable information on the use of fenbendazole in breast cancer treatment.

  154. 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.

  155. Todd

    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.

  156. Tami

    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.

  157. 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.

      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.

  163. 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!

    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.

    Filling lot better blood test better than perfect.

    1. fenbendazole

      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!

  169. 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.

  170. 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.

      4. JH

        So disheartening. How did this protocol work for you?

      5. Kate

        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?

      6. Ellon Morgs

        Marsha, I’m so sorry to hear about what your husband went through, and you as well.
        Did you use this protocol? What were the results?
        Thank you and prayers

      7. Ann

        How are you doing now, Marsha?

      8. Sara

        Marsha. I hope you reply and that you are feeling amazing. I would love to hear how you’re doing.
        My husband was just diagnosed with PTCL non Hodgkins and I have received the order for him.
        Than you so much! Sara

      9. Gloria

        Heartbreaking. Hope you are doing well and having success 🧡

      10. Mary Janis

        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.

    2. Caroline Poole

      Hi Deborah – many hugs and blessings to you, warrior woman! How are you doing since you wrote in August?

    Thank you so very much !!!

    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.

  173. 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.
      Bio-Available Curcumin 600 mg. Take 1 capsule two times a day after breakfast and lunch with no pauses.

      Dear Peter, thank you for the comment.
      It is really hard to find fenbendazole in capsules, because it is mostly used as a dog deworming agent. You can find capsule form at online stores. We have a list of reputable suppliers, that are known worldwide. Please visit our page section called “SUPPLIERS”.

  184. Kevin Brown

    Thank you so much for this. The cancer community shares so generously.
    I have been using Rife frequencies, without success, for a year on a colon tumour. Possibly the addition of Fenbendazole will do the trick. Thank you. KB

      Dear Beth,

      Thank you for your question. Fenbendazole is readily available for purchase through various channels. For example, you can conveniently order it online from reputable suppliers listed in our “Suppliers” section. Alternatively, if you prefer, you can also find Panacur at local retailers such as Walmart or veterinary supply stores.

      Best regards

  186. Donny Wheeler

    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?

  187. 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.

  188. 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.

    2. Ionut Ciprian

      My mother has lung cancer.she is 50 kg .what’s the best dosage for her.she also have chronic pancreatic and diabetes. Thank you.

      1. fenbendazole

        Dear Ionut,
        Depending on your mother’s weight and treatment goal, she should take 222mg of Fenbendazole, 6 days a week. You can find more information using our dose calculator:
        It is also crucial to monitor your mother’s overall health. Regular blood tests and blood sugar level checks are important, as well as checking liver enzymes every few months. This ensures the safe use of Fenbendazole and helps achieve the best results with minimal harm.

  189. Aidan

    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.

    3. Nina Kay Mackey

      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

  190. 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.

    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:

  193. 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.

    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 ?

      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.

    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.

        Has there been any positive testimonies on using this with kidney cancer?

          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.

  196. 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

  198. 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.

      I know this is from 2020…. what a nightmare of a year! Anyway, I wondered how your husband made out. God bless.

  199. 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.
