Ivermectin Access and Controversies

Expert Opinion: Dr. William Makis

Dr. Makis emphasizes that Ivermectin has shown anti-cancer activity against over 20 types of cancer. However, due to its low cost and off-patent status, clinical trials remain unlikely. Studies in mice have demonstrated effectiveness in breast, colon, glioblastoma, glioma, and leukemia, but more research is needed for lymphoma, testicular cancer, and sarcomas.

IVERMECTIN acts on Cancer mainly by inhibiting signaling pathways involved in cancer proliferation (Akt, Wnt, mTOR) and also by inhibiting CANCER STEM CELLS.

Access to Ivermectin

In many countries, Ivermectin is available over the counter. However, regulatory bodies often impose restrictions, as seen in cases where physicians were penalized for prescribing it. Advocates argue that such restrictions deny patients access to potentially life-saving treatments.


Fenbendazole: Key Resources

Fenbendazole, another antiparasitic, exhibits at least 12 anti-cancer mechanisms. Studies indicate its effectiveness against triple-negative breast cancer, colon cancer, glioma, and leukemia. The ketogenic diet may enhance its therapeutic effects.


Oct.3, 2023 - FENBENDAZOLE and CANCER - at least 12 Anti-Cancer mechanisms of action. Not approved by FDA. Cheap. Safe. Kills aggressive cancers. Why no Clinical Trials? Nine research papers reviewed.

Experimental Cancer Protocols

For aggressive cancers, high-dose Fenbendazole (444-888mg/day) or Mebendazole (up to 4g/day) may be considered. Clinical trials support Mebendazole’s safety at high doses.
  • You can look at fenbendazole.org for suggested dosing and dose calculator
  • Dr.Tom Rogers, Founder of “Performance Medicine” has similar protocols.
  • For anyone COVID-19 mRNA Vaccinated diagnosed with cancer (Turbo Cancer), I’d probably be looking at starting at 444 mg a day.
  • For particularly aggressive Turbo Cancers or bad cases, I’d even consider pushing towards 888 mg/day (444 mg twice a day) or 1000 mg/day.
  • Highest dosing I’ve seen is 30-50mg/kg/day for 5 days, based on the “Merck Manual”, however very few claim to have taken this dose.
  • Fenbendazole can elevate liver function tests, so it would be a good idea to have a family doctor monitor those

Mebendazole: Key Resources

    Here are the references for this dosing schedule:

  • For Maximum dose of 4g/day being safe, that’s from a Phase 2 Clinical Trial for Gastrointestinal Cancer: (2021 Mansoori et al)

  • (2021 Chai et al) - summarizes the various studies that have looked at Mebendazole in Cancer and the doses used.

  • So far, several studies in the literature have used 200mg/day with some success, however given that it is safe to go up to 4g/day, when we’re dealing with aggressive mRNA Induced Turbo Cancers, 200mg/day is probably not sufficient.

  • Why Mebendazole over Albendazole (2021 Chai et al):

    “However, because of the toxicity of albendazole, for example, neutropenia due to myelosuppression, if high doses are used for a prolonged time, mebendazole is currently more popularly used than albendazole in anti-cancer clinical trials.”

New & Improved Joe Tippens Protocol

The holy grail turbo cancer treatment may just be the synergistic combination therapy of Fenbendazole AND Ivermectin as follows:

  • Fenbendazole (300mg, 6 days a week) or in the case of severe turbo cancers up to 1 gram/day.

  • Ivermectin* (24mg, 7 days a week) or in the case of severe turbo cancers up to 1mg/kg/day (Find a Doctor)

  • Bio-Available Curcumin (600mg per day, 7 days a week).

  • Vitamin D (62.5 mcg [2500 IU] seven days a week).

  • Lifestyle: Eliminate sugar (BMJ 2023), adopt a whole-food diet, avoid ultra-processed foods (BMJ 2024), prioritize sleep, and manage stress.

Please note that this protocol now includes the vital Vitamin D addition, with the one day off for the fenbendazole administration. This protocol represents the most comprehensive and cutting edge repurposed drug and vitamin treatment approach to date.

*Note: If you are already taking ivermectin and mebendazole, you may not need to add fenbendazole. Always consult your doctor before making any changes to your treatment plan.

Fenbendazole and Mebendazole Cost

Fenbendazole is cheap. If big pharma is going to make money (especially in cancer treatment), they need an expensive compound and Fenbendazole isn’t it.

Dr. William Makis’s Take on Fenbendazole & Mebendazole

While research on Fenbendazole and cancer continues, scientists are increasingly focusing on other compounds in the Benzimidazole family, including Mebendazole, Albendazole, and Parbendazole. 

If I were diagnosed with mRNA-induced turbo cancer as a male in my 40s, I would strongly consider a combination of Ivermectin (1mg/kg/day) and Fenbendazole (444mg/day). This decision would be based on numerous peer-reviewed studies, ongoing clinical trials, and existing research.

"Everyone’s situation is different, but it is crucial to arm yourself with medical knowledge that oncologists may not provide, either due to a lack of awareness or fear of professional risk."

Research Gaps and Future Directions

We recognize that double-blind, prospective, randomized controlled trials (RCTs) remain the gold standard in medical research. However, alternative study designs, such as N=1 trials, open-label studies, and real-world data analysis, provide practical insights—especially for rare or advanced cancers where large-scale RCTs may be impractical due to cost and time constraints. While these methods lack the rigorous controls of RCTs and are more susceptible to bias and confounding factors, they still offer valuable evidence that should not be overlooked.

For patients with Stage 4 or aggressive cancers, considering all available treatment options is essential, given the high-risk, high-reward nature of their condition. In such life-threatening scenarios, patients should have the "right to try" experimental or off-label treatments if standard options have been exhausted.

While clinical guidelines are informed by research, real-world patient care is not always dictated by clinical trials alone. Personalized treatment can be seen as a series of N=1 trials, where multiple interventions are carefully tested on an individual basis. By combining empirical evidence, clinical expertise, and real-time assessments—including cancer markers and PET scans—physicians can closely monitor treatment responses and adapt strategies quickly to maximize both effectiveness and safety.


Conclusion

Ivermectin, Fenbendazole, and Mebendazole show promise as experimental cancer treatments, supported by emerging research across multiple cancer types. However, clinical trial data remain limited. Patients should consult healthcare professionals before pursuing these protocols.

Fenbendazole vs Ivermectin for Cancer: Differences and Which Is Better?

By Editorial Team
Image
Cancer patients are increasingly inquiring about the use of the anthelmintic drugs Fenbendazole (FenBen) and Ivermectin (IVM) as potential treatments for cancer. Notably, these patients typically fall into two distinct groups, neither of which represents the usual stage 1 or 2 cancer cases where conventional therapies often show promise. The first group consists of older men whose lung or prostate cancer has recurred. Having undergone conventional treatments previously without success, they express skepticism about its effectiveness this time around. The second, larger group comprises younger patients under 40 dealing with aggressive breast cancer, colorectal cancer, or lymphoma—forms of early-onset cancers that appear to lack the typical mutations observed in traditional cases. This article aims to delve into the differences between Fenbendazole and Ivermectin by examining their mechanisms of action, approved uses, and the latest research on their efficacy across various medical con...

Fenbendazole Dosage for Cancer in Humans: Benefits, Risks, and Guidelines (2025)

By Editorial Team
Image
What is Fenbendazole? Fenbendazole is an anthelmintic drug commonly used to treat parasitic infections in animals. However, recent research and anecdotal reports suggest it may have potential anticancer properties in humans. How Does Fenbendazole Work for Cancer? Fenbendazole is believed to work by disrupting microtubules in cancer cells, leading to cell cycle arrest and apoptosis (cell death). Some studies suggest it may also modulate glucose metabolism, limiting cancer cell energy supply. Recommended Fenbendazole Dosage for Cancer in Humans The commonly referenced Joe Tippens Protocol suggests the following dosage: Potential Side Effects of Fenbendazole in Humans While generally considered safe, potential side effects may include: Gastrointestinal discomfort (nausea, diarrhea, bloating) Liver enzyme elevation (rare) Bone marrow suppression (rare) Safety and Precautions Medical Supervision: Always consult with a doctor, especially if combining with other treatments.

What is the "Stanford Fenbendazole Protocol"? I bet you've never heard of the "Stanford Fenbendazole Protocol" for treating Cancer. Yet, it exists. But it's heavily suppressed by search engines and mainstream Oncology, especially in the United States and Canada. In 2021 a group at Stanford University Medical Center, Department of Medicine, published a Case Series (Clin. Oncol. Case Rep 2021)* on a "forbidden" repurposed drug, Fenbendazole. *Note: Clinical Oncology Case Reports is a peer-reviewed International clinical and medical oncology and cancer research Journal. Clinical Oncology Case Reports (COCR) is a high-impact multidisciplinary journal focus on the area of clinical and medical investigation. They wrote about 3 cases of Stage 4 Cancer patients who self-treated and cured their cancers.   Case 1: 63 year old man with a Stage 4 Renal Cell Carcinoma (clear cell) , a 5.3cm mass and mets to pancreas and bone, failed 3 lines of chemo.

Eat These Foods to Starve Cancer Cells to Death (2025)

By Editorial Team
Image
Some people may not realize this, but many people have cancer cells in their bodies without presenting much danger. Fortunately, there are some common foods that can cut off cancer cell’s nutrient supply and starve them to death. Autopsies of individuals who died of trauma often reveal microscopic colonies of cancer cells , also known as in situ tumors. Some people call them “disease-free cancers.” For instance,  researchers  in Denmark performed autopsies on women aged 40 to 50, who  never  had cancer during their lifetime, and found that 39 percent of them had small cancerous lesions in their breasts. Only 1 percent of women in this age group would be diagnosed with breast cancer. Examination  of some men in their 60s showed that 46 percent of them had histological evidence of prostate cancer, which is consistent with the findings of the autopsy study. However, the prevalence of prostate cancer in men aged 60 to 70 is actually around 1 percent....

Ivermectin to Treat Cancer in Humans (2024)

By Editorial Team
Image
Ivermectin is a widely used antiparasitic drug that's listed on the World Health Organization's essential medicines list 1   and approved by the U.S. Food and Drug Administration. In low- and middle-income countries, ivermectin is commonly used to treat parasitic diseases including onchocerciasis (river blindness), strongyloidiasis and other diseases caused by soil-transmitted helminthiasis, or parasitic worms. 2 The drug is also used to treat scabies and lice. It's estimated that the total number of ivermectin doses distributed is equal to one-third of the world's population and, as such, "ivermectin at the usual doses (0.2–0.4 mg/kg) is considered extremely safe for use in humans." 3 Ivermectin also has demonstrated antiviral and anti-inflammatory properties and made headlines for its potential role in treating COVID-19 4  — although much of the positive press has been censored and falsely labeled misinformation. 5  Now researchers are highlighting another p...
