Hello and thank you for your informative website. I have read many pages and Q&A and also searched online so thought I would ask here….. have you had any patients or experience with uterine fibroids (non cancerous) being elliminated or even just reduced in size with fenben use? I am currently doing a parasite cleanse 222mg for five days and will repeat in a few weeks but wonder if that would be enough for fibroids or if I should do it more rigorously. Would love to hear your thoughts. Many thanks
Hello Janelle,
Thank you so much for your kind words about the website. It means a lot that you took the time to read so many pages and Q&A before writing.
Regarding your question: at the moment there are no solid, published human data showing that fenbendazole can reliably eliminate or shrink non cancerous uterine fibroids. Most of the research and reports around fenbendazole focus on cancer, and fibroids are benign growths with a very different biology and with their own set of standard treatment options like hormonal therapies, embolization, or surgery when needed. Because of that, there is not a clear evidence base to say that a parasite cleanse‑type course of fenbendazole will reduce fibroid size.
Your current plan of 222 mg for five days is in line with short parasite protocols, but such a brief pulse is usually designed for deworming rather than long‑term changes in tissue like fibroids. Whether a more rigorous, longer schedule would actually affect fibroids is simply unknown at this point – there are no good studies to guide how to dose fenbendazole specifically for benign uterine fibroids, so anything in that direction would be experimental and based more on theory and extrapolation than on direct proof.
If you decide to continue, it may help to think of fenbendazole as one small, unproven piece in a much bigger picture: overall hormone balance, diet, stress, iron levels, and the well‑studied options that are known to help with fibroid symptoms or size. Keeping track of your symptoms and any imaging over time is the best way to see whether what you are doing is making a meaningful difference for you personally.
Thank you so much for your detailed reply and for being so easily reachable. Yes it will be interesting if what I am doing will help along with high dose vitamin d & k supplements. I will be sure to update here if I have success!
Hello, I recently got diagnosed with Papillary Thyroid Cancer, I read the book Cancer is a Parasite, but can’t find any evidence on fenbendazole helping with my type of cancer, even though it helps on way more agressive cancers. I just want to know if it will actually erradicate my 2 malign nodules. Thank you!
Dear Paola,
At the moment there is no clinical research showing that fenbendazole has been specifically tested in papillary thyroid cancer or proven to eradicate malignant thyroid nodules in humans. Most of the data we have are laboratory studies and small case series in other tumor types, where fenbendazole acts as a microtubule‑interfering and metabolism‑modulating agent, but these results cannot be directly translated into a guarantee for your cancer type or for complete nodule clearance.
For thyroid cancer specifically, the strongest experimental signals actually come from a related benzimidazole drug, mebendazole, which has shown activity against papillary and anaplastic thyroid cancer cell lines in preclinical models, but even there human trial data are still missing. Because of this, we cannot say that fenbendazole will eradicate your two malignant nodules; at best, its potential role in papillary thyroid cancer remains theoretical and should be considered only as a possible adjunct to standard care.

I’m taking Merck Panacur C (fenbendazole) 222 mg granules 1 pack a day and it says each packet is for 10lbs. My question is I weigh 80lbs so do I need to just take the one packet for 10lbs or take 8 packets for my 80lbs body weight?
Hello, Ethel.
You need 1 packet a day. It is written “for 10 lbs” because Panacur C (and its single-packet 222 mg format) was originally designed and labeled for animals as a deworming product, where the standard dose is calculated as 1 packet per 10 lbs of animal body weight. The label reflects veterinary antiparasitic dosing rules, not human cancer adjunct use.
I your case you may need 1 packet (222mg), and if you feel fine after a few weeks (no side effects, liver enzyme levels not changed) you may increase dosage a bit (one and a half to two packets). But 222mg is a good dosage for 80lbs person. ALSO take care of your liver health and immune system with supplements like: milk thistle, magnesium, zinc, Vitamin D3 + K2, Omega-3, TUDCA.
Hi, is fenben good for HPV 16?
Dear Lisa,
Thank you for your question. At this time, there is no established evidence that fenbendazole specifically targets HPV-16 or clears human papillomavirus infections in general. Fenbendazole is being explored for its potential metabolic and anti-proliferative effects, but these mechanisms are not known to directly affect viral persistence.
Some individuals choose to use fenbendazole as part of a broader wellness approach, yet it should not be considered a proven therapy for HPV-16. Monitoring your overall health and following appropriate medical screening guidelines remain important.
Does ivermectin or fenbendazole work on herpes virus? If so what is the protocol?
Dear Lucretia,
While Ivermectin has shown some antiviral properties in laboratory studies, including limited effects against certain herpes viruses, clinical evidence in humans remains minimal. Fenbendazole, although originally developed as an antiparasitic, is now also used off-label as an anticancer compound due to its ability to disrupt cellular microtubules and support immune responses. While neither is considered a primary treatment for herpes, both are sometimes used in off-label protocols aimed at supporting overall health and immune function. Ivermectin is typically taken at 0.2 mg per kilogram of body weight once or twice per week on an empty stomach, while Fenbendazole is often used at 222 mg per day for six days on and one day off. Supportive care like liver supplements and proper hydration is also recommended.
Can Fenben be used in humans for parasite elimination in humans?
Hello Nan,
Yes, Fenbendazole can be used in humans for parasite elimination. It has been shown to be effective against certain parasitic infections in humans as well. If you are considering this treatment, it is important to follow the correct dosage. You can use the dosage calculator available here to find the appropriate amount: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
can Fenbendazole be used to rid the body of molds and mycotoxins?
Hello Katherine,
Fenbendazole is not typically used for mold or mycotoxin exposure. Molds and mycotoxins are better managed with antifungal treatments, detox protocols, and environmental controls to reduce exposure.
If you are dealing with mold and mycotoxin issues, it is crucial to consult a healthcare professional for proper treatment and personalized recommendations.
