What Is Fenbendazole and How Can It Affect Cancer Treatment?

  • Post comments:63 Comments

If you have animals, then you’ve definitely heard of Fenbendazole. Fenbendazole is a drug used for parasite and anti-worm treatments in animals. It is a common drug for veterinary use. The primary use of this particular drug is to destroy worms such as hookworms, roundworms, tapeworms, parasites, and whipworms.

So, what does this drug have to do with cancer treatment? Plenty of different studies show that this drug can do much more than that. It can:

  • Destroy cancer cells
  • Interrupt the sugar uptake in these particular cells
  • Help with drug resistance caused by cancer
  • Reduce the size of a tumor.

Here, we will focus on one particular study conducted in 2008. We will talk about this drug in detail. What makes it so good, and could it really have these potential benefits studies say they do. Let’s delve deeper into the often-overlooked drug called Fenbendazole.

Why Are Vitamins Important for an Effective Cancer Treatment with Fenbendazole?

Fenbendazole has always been the go-to drug for treating rodent pinworm. It is easy to use, and there aren’t any scary side effects. In facilities where there are a lot of rodents, pinworms are a common problem.

In this study, Fenbendazole was used as a part of a diet because of how safe it is. There are rarely any side effects. But, the drug showed unexpected positive results.

To test the effects of the drug on cancer cells, researchers used xenografts. These are experimental cancer cells implanted in animals for testing. They were tested on mice. According to the statistics, the cancer cells failed to grow. The main reason was the Fenbendazole.

  • Mice received a pre-treatment of Fenbendazole, which proved effective for preventing tumor growth.

When the Fenbendazole was combined with vitamin supplements, it showed potent anti-tumor properties. The vitamins included in this particular study were E, B, D, K, and A. All of these vitamins are known for their antioxidant properties.

 

The statistics show that Vitamin E has powerful anti-metastatic and anti-tumor effects in animal studies. The main purpose of this vitamin is to suppress the tumor. Based on the same research, consuming plenty of vitamin B and dietary folate can be effective for reducing colorectal cancer in women.

The drug alone doesn’t have the same beneficial properties. In fact, it doesn’t even affect tumor growth. But, when combined with the vitamins, it is a completely different story. As a result, the combination of vitamins with Fenbendazole seems promising. Without these vitamins, the drug wouldn’t be that effective.

However, more research and substantial evidence are necessary to analyze the cell types. Depending on the substances used during testing, the results can differ.


Fenbendazole Against Lymphoma Cancer

 

Fenbendazole can be effective against different types of cancer cells, including Lymphoma. The main reason being the size of the tumor. Since the drug blocks the glucose in the cancer cells, it deprives them of their main source of fuel – sugar.

In this particular graph, you can see the results of the treatments for reducing tumor volume. There were four different diets. The mice first received lymphoma cell injections and then a specific treatment based on their group. One group received Fenbendazole, other just vitamins, and a third group received a combination of both. All of them were compared with the controlled group. As you can see, the group that received a combination of Fenbendazole and vitamins had far more significant results compared to the rest of the groups. This proves how effective a diet with vitamins and Fenbendazole can be for reducing tumor volume.

Fenbendazole works in a similar way to colchicine (a known destabilizing agent). But, it can’t compete with Taxol or other Vinca alkaloids. It adds anti-cancer properties in its own way. In other words, this drug could be efficient for supporting metabolic therapies, radiotherapy, and chemotherapy.

What About Using this Drug on Humans?

Even though this drug is typically used in veterinary medicine, humans can still tolerate it. According to the European Medicines Agency, humans can tolerate a specific dose of Fenbendazole. More precisely, for ten consecutive days, a human can handle 500 mg. But, if it’s a single dose, it can be up to 2,000 mg.

Conclusion

Despite the current primary use of Fenbendazole, this drug has a lot more potential. It could be a valuable anti-cancer drug. This study focused on tumor growth and how the drug affects it. Since cancer cells use sugar as their main source of fuel, researchers tested the Fenbendazole drug to see how it will affect the sugar uptake. When combined with vitamins, this drug showed positive results. The size of the tumor significantly reduced more than compared to other controlled groups. Since this drug interferes with glucose metabolism, it can be effective for cancer therapy.

This drug is often ignored because we use it on animals. But, humans too can handle it. It is a safe drug with little side effects. What is important is the strategy used to make the most of its benefits. Repurposing this drug for cancer treatment not only could be beneficial, but it can also be cost-effective.

It could reduce the cost necessary for developing new and expensive drugs.

    My husband will be starting chemo therapy
    in 3 days for tumor and some lymph nodes in lung.Can fenbendazole be used while doing chemo?

    1. Dip

      Looks like people have been using it …Check Joe Tippens My cancer story rocks and see his viedeo so you can see how he used Fenben…

      My prayers and good luck

    2. Steve Sevek

      Yes. Fenbendazole can be used while taking chemotherapy.

    3. Ben

      Hi,
      This article states that it can help when combined with chemo, it also recommends taking the vitamins listed.

  2. Joseph clark

    Your saying Fenbendozol without vitamins will have very little affect is a lie without any real study! I had stage 4 kidney cancer that had spread to my IVC, right atrium of my heart, both lungs, pancreas, hip and spine.
    In April of 2019 I was deemed terminally ill with six months to live. Last ditch treatment was immunotherapy. I was given 3 half doses and it was determined that I became highly toxic from the treatment which caused pancolitis. Treatment was terminated. Now first week of August started taking Fenbendozol NO vitamins no CBD. Now second week of October 2019 MRI scans at Stanford shows my largest tumor in my left kidney was GONE! All other tumors shrinking considerably! Now January 2020 Stanford MRI scans show no evidence of disease!! (NED) all cancer gone! I’m still taking Fenbendozol 3 days on four days off consistently. No vitamins at all!!! STANFORD now producing Fenbendozol in there lab for human study ! I’m living proof of Fenbendozol treatment with no vitamins. It doesn’t mean they won’t help but they aren’t needed to kill cancer cells either. All my records are proof positive and can be reviewed.
    Joe

    1. Chris Andrew

      Wondering if you can elaborate a bit more? What dosage did you take starting in August? Now that you are healed, are continuing to take Fenbendozol? If so, what dosage and frequency?

      I also started taking it as I began my radiation and chemo treatment for rectal cancer. I took a dose of 200 mg/day for 3 days, with 4 days off.

      I am now taking that same dose, but only for 1 week/month.

    2. Jaime

      Hi Joe, so glad to hear of such success. Congrats! So do you need to keep taking fenbendazole for the rest of your life? Have you noticed any negative side effects especially regarding liver or kidney function? Eagerly awaiting your reply.

    3. JAIME ABADIE

      Hi Joseph, Congrats on your success! Do you know the name of the study that Stanford is doing? How did you take the fenbendazole? Did you take it with some type of fat or water? Did you take it in the morning or at night? Thanks for the info.

    4. Bobbie

      Joe, that’s amazing. What is your daily dose in your 3 days on and 4 days off regimen??

    5. Hazel Mears

      That is fantastic I’m so pleased for you. I wish I knew about Fenbendazole a couple of years ago when my mum was dying of Bile duct cancer! People are so sceptical about putting a dog dewormer in to their body but quite happy to put a toxic poison in there! Strange.

    6. Mary

      where do you get this? Most doctors won’t prescribe.

    7. Shelly

      Are you taking just the powder form of panacur or safequard for dogs?

    8. Tiffany

      Hi, I’m glad to hear this worked for you. May I ask what dose regime you were using?
      Thank you,
      Tiffany

    9. Nik

      Congratulations! What was the dose you took? And did you take 3 days on 4 days off? What did you eat and what did you refrain from eating during that time?

    10. chip

      How are you doing today? And how did you get started with Fen? My dog has lymphoma

    11. vicky

      how much fenben did you take Joseph

    12. Deborah

      That is very encouraging, and the first report I’ve heard specifically from someone who had renal carcinoma. Thank you for sharing this info.

    13. Paula Orr

      Are you still doing well?

    14. Rebecca

      Awesome what was your dosage if you dont mined me asking..iam 188 lbs just wondering did you take whole pack or just go by weight??

    15. Dave Long

      Hello Joseph, Congratulations on your cure, that is wonderful news. I am wondering what dose you were taking and is it available over the counter? Where can I buy it without a prescription as a preventative measure?

    16. Angel B

      Wow! First, congratulations! Second, thank you for sharing your story. I think it is interesting that you came across this blog and we’re able to share your story, it will help so many like me. I have friends and family members suffering from different types of cancer and in different stages. I will be passing this information and your experience to them so they can reach their conclusion on it. I will be looking into taking it as a preventive measure. Thank you again for sharing your experience and again, congratulations on your health!

    17. Heidi

      That’s great news Joe! Congratulations!

      I’ve been giving it to my dog who has 4 tumors in the liver and spleen and a stage 4 heart murmur. I also add 3-4 drops of DMSO to the mix with vitamins. He takes it orally in raw food and his swelling has gone down tremendously. I’ll also rub the DMSO on his belly at night before he goes to bed.

    18. Worried Friend

      Hello Joe I have a friend who has cancer and her doctor told her that 97% of the time his patients who did this end up dying. What do you think? When she told me that my first thought was how much money is her doctor getting for here having cancer. I could be wrong but you never know.

    19. Jeff

      Just Curious Joseph my wife has ESS IV which is endometrial Stromal Sarcoma and I ask the Dr about taken the fenbendazole and they knocked it down instantly. Just curious if there are more stories with facts

    20. Alex McDougall

      Hi Joseph I was wondering what dosage were/ are you taking please? Any help or advice would be hugely appreciated

    21. Cherree

      Hi Joe

      I’d just like to know how you are doing? Are you still cancer free?

      I have a friend with Lymphoma cancer, and I’d like to send him something positive…if that is indeed the case.

      Best regards
      Cherree

    22. Warren Church

      Clark, I just started taking Fenbendazole one 222mg tablet once a day for three days and then three days off and then three days on again. I want to kill and intestinal parasites and worms. What amount of Fenbendazole (MG) are you taking for your cancer? Thank you

    23. Christina A Kinne

      Thank You Joe for sharing your success! Yes, I looked up this drug as I had heard another similar story to yours on curing cancer with this medicine! Bravo!

    24. Ali

      What were you taking? Goat or horse dewormer?

    25. Ben

      Hi Joseph,

      This is great news, I’m glad that you are recovering. I think that this article says that with a combination of vitamins that the tumor will shrink more. The Fenbendazole still stops the tumor from growing bigger, but you actual get more reduction with the vitamins combination.

    26. Tom

      Amazing journey Joe, thanks so much for writing it here. You’re a human phoenix!
      All the best and congratulations.
      Tom

    27. Amanda Burns

      Can I ask what the dosage was that you took initially? And what was the maintenance dosage.

    28. Amy B

      Brilliant! About to try for my dog’s lymphoma. Well wishes to you!

    29. Nancy

      Dear Joe,
      I would love to know how you’re doing. This is so amazing. I’ve been paying attention to Fenbendozol as a cancer treatment. Would you please update us to let us know how you’re doing? I hope everything is great for you. I have a very good friend who has stage four cancer in many areas including breasts and spine.
      Please let me know. I hope you see this!

    30. Suzie

      Joe, how much are you taking?

    31. Cheryl McDuff

      Hi Joe. Just wondering how you are getting on.

      Hopefully you are still showing NED

      Joe may I get in contact with you?
      Thank you
      Shawn

    33. Amanda K.

      Joseph can you tell me your regimine for taking it? My dog was diagnosed Fri with aggressive cancer and given “a week or so” to live. Today is day 3 of the Fenbendazole. I have read in several places that you give 3 days on/4 days off. Is this what you did? if he only has a week or so will this even be effective?

  3. Orion

    Thank you for shating this.what protocol did you use?

  4. Nick

    Thats great omg…
    Congratulations for you and will pray for your long healthy life.
    Are you still NED?
    When was your last MRI/PET SCAN?
    Can you please tell me how many days cancer patient should take Fenbendozol?
    I believe god is there for us.

  5. Ruth dirse

    thanks Joe wanted to know if you would release your medical records but have not received an answer also would like to know about Stanford research Ruth

  6. Gary Wright

    Joe. Thank you for your post of 22 May 2020. I was diagnosed with Stage IV cancer in my right lung in Jun 2019 with a life expectancy of 6 to 12 months. The side effects of Chemo was literally killing me and I declined treatment after the 3rd session. Since then I have been on immunotherapy, Keytruda, every 3 weeks with limited success. I found your post very encouraging and am on my 5th round of 3 on 4 off of fendendazole. My next CT and MRI is in 4 weeks and I am excited for the results. Thank you again for your post, it provided me with hope and motivation.

  7. Debbie

    That is incredible Joe. Congratulations and keep fighting! What dosage are you taking and at what frequency? I see the dosage suggestion of the 10 days but what after that? Do you know?
    Thank you in advance

  8. Colleen

    Joe Clark, can you tell me what dosage of Fenbendazole you are using? I have a 23 year old family member battling brain cancer for a second time. Thank you so much!

  9. Rudy

    That’s awesome. How many mg did you take in each of them three days?

  10. Jeff Wacker

    Joe how much Fenbendozol are you consuming on you 3 days on 4 days off..

  11. Dominique

    Mr Clark
    What kind of dosing were tou taking? What was your weight and height. Can you share the name of the Dr. overseeing your Fenbendozol treatments?

  12. Dawn Denise Babilon

    Hi Joseph. I know this is a very old post and I hope you get this message. Please tell me the fenben protocol you used as treatment. Thank you.

  13. Janice Hafen

    Janice H. I was diagnosis with Rt Breast cancer in Feb. 2021. Scan showed tumor size of 5.3cm on 2/3/21. I heard of Fenbendazole a few days afterward and started taking 222mg for dog de wormer. I had surgery to remove the tumor on 3/17/21. The tumor size was 2.3cm with flat edges a good sign. I also was taking Vit A,B,D,E and K without even knowing this would help. I will be taking radiation for 6 weeks but did not need Chemo. I an very happy I miraculously heard about this product. Thank You.

  14. Liz lichtnet

    Dear Mr Clark
    My husband Jeffrey has stage 2 of pancreatic cancer he was give his first dose of chemo too strong than the lowered it in the mean I should mention he had whiple surgery before given chemo he ended up with sepsis cellulitis was in and out of rehab and hospitals he had an inferior vena cava inserted to stop clots long story short he is in hospice now😞 was given possibly 6 months
    How does one go about getting this fenbendazole?? I am desperately in need of all the help I can he was healthy no underlying illnesses no drinking or smoking or drugs please respond to my email 🙏 liztennis@comcast.net
    I beg you to reach out 🙏

  15. Allan

    Thanks for your post Joe . Hope you continue to do well. Also another medicine for animals IVERMECTIN works very well against COVID. but big pharma doesn’t want you to know it!

    Joseph Clark can you please contact me at hope4trin@gmail.com. I would very much like to arrange to receive a copy of your clinical records. Thank you.

  19. Val Pain

    Hi Joe want a amount did you take per day? Thanks Val

  20. A. Gwen Baldwin

    Thank you. You have given a lot of us some hope!!

  21. Diana

    Amen brother, glad to read your results. I was wondering if Vitamins really make it or break it combined with Fenbendazole. Thank you for your response. And also glad you had such success. I am now trying to kill my Lymphoma. But I believe the dose, 3 days on, 4 days off is really for the life cycle of the worm. 3 days to kill the adults, 4 days to wait for the eggs to hatch then another 3 days to kill the hatched baby worms, etc….so I’m going to take 222mg (1 packet) once a day. According to the weight graph I should take more mg. But we’ll see. Thank again

  22. Catherine Nelms

    Joe, I was recently diagnosed with HCC with liver primary, staging yet to be done but thought to be in early stage. Should I start treating myself with Fenbendozol and at what MG? Thank you for your thoughts!

  23. Ky

    Joe,
    This information is flooring me! I’d love to know how much you took, how often. Your testimony is truly amazing. Since I was diagnosed (stage 3 larynx), I decided can heal without destroying my body with chemo/radiation. Thank you so much for sharing this, It gives me hope.
