Ivermectin/Fenbendazole dosage for cancer?

My wife has advanced (3C) ovarian cancer, diagnosed in 2023. She has had extensive surgery and just completed her second course (six infusions) of Paclitaxel/Carboplatin.

She has been taking 18mg/day Ivermectin, plus D3, vit. C and some other supplements, for around one year. I have ordered some Fenbendazole tablets too, which we hope to receive tomorrow.

May I ask what the current wisdom is for dosage when taking BOTH IVM and Fenb?

Hi @stevesp I am sorry to hear about your wifes cancer.

Please have a look though all our free cancer resources, $14 Billion Later, Cancer Is Worse Than Ever. Where Did the Money Go?

The Approach to Repurposed Drugs Protocol will be helpful.

Many cancers can be slowed—or even reversed—by targeting cancer stem cell (CSC) pathways using existing drugs in novel combinations. The protocol emphasizes:

Ivermectin, doxycycline, curcumin, and mebendazole (among others, including lifestyle interventions)

Two core strategies:

Limited therapy: Conservative use with conventional care

Aggressive therapy: High-dose, multi-agent support for aggressive tumors

I highly recommend McLelland’s book: How to Starve Cancer: …and Then Kill It With Ferroptosis: McLelland, Jane: 9780951951743: Amazon.com: Books

I have had one patient who completely cured her stage 4 uterine cancer with her protocols. Her website is helpful. I have a summary of what she and her partner used in a Word doc. Reach out to me privately if you would like this: hello@aimedicine.life

Wishing you the best on your journey.

Hi, I just recently saw an ad on TV that advertised the use of a parasite detox, and I noticed that its contents included mainly ivermectin and febendazole. And later this morning I looked it up online and found a formulation by Jase Medical for the same thing, but it contained ivermectin and mebendazole, in a ratio of 25 mg ivermectin to 250 mg mebendazole. So, the ratio is about 10 to 1, mebendazole to ivermectin. Wishing your wife a swift recovery!

I have seen both Febendazole and Menbendazole mentioned in various protocols but never both with an ‘or’ in the middle. I know that they are from the same family of drugs with similar functions/effects but are these drugs simply interchangeable or are they cancer/COV19 specific?

Hi shortstop - here the AI info, but in the IMA protocols/guides you’ll only find human use drugs. Thus nothing so far for Fenbendazole. Menbendazole is in the Cancer Guide.


AI question: The difference between Febendazole and Menbendazole?

AI answer:

Both drugs share a benzimidazole core but differ in side chains: Menbendazole has a carbamate group, while Febendazole has a thioether linkage with a phenyl ring.

  • Both act by binding to β-tubulin in parasitic cells, disrupting microtubule formation and leading to parasite death.

Medical and Veterinary Use

  • Menbendazole is primarily used in human medicine for roundworms, pinworms, hookworms, and whipworms, and is FDA-approved for human treatment.
  • Febendazole is mainly used in veterinary medicine—dogs, cats, horses, and livestock—and is not approved for human use by the FDA.
  • Menbendazole is prescribed for human use; Febendazole is available over-the-counter for animals but should be administered with veterinary guidance.

Effectiveness and Spectrum

  • Menbendazole is most effective against roundworms, pinworms, hookworms, and whipworms.
  • Febendazole has a broader spectrum in animals, targeting lungworms, tapeworms, liver flukes, and some protozoans.
  • Febendazole’s higher affinity for nematode tubulin may explain its broader efficacy in certain species.

Safety and Availability

  • Menbendazole: Well-studied in humans, generally safe, requires a prescription.
  • Febendazole: Safety in humans is less established, risk of liver damage, typically inexpensive for animal use.
  • Interchangeable use is not recommended due to regulatory and safety differences.

Notable Research and Off-Label Uses

  • Both are being studied for anti-cancer effects, though Menbendazole has more human data and established research.
  • Febendazole is gaining popular interest for potential cancer therapy, but human safety data is limited.

In summary, Menbendazole is used for human parasitic infections and is FDA-approved, while Febendazole is a veterinary drug not approved for human use, with broader use in animals and ongoing research into potential new therapies.

Well there is now an update about **Fenbendazole from one of our Senior Fellows, **Michael Turner M.D.

We restacked his substack Cancer Fighters: Fenbendazole and Mebendazole

And it’s well worth a read.
