Mebendazole vs Fenbendazole for Cancer Treatment

Mebendazole vs Fenbendazole have both garnered online interest for purported cancer-curing properties. Social media and patient forum posts have raised expectations for these medications as cancer cures.

 Initial lab studies on these drugs have produced exciting results, however, it is essential to evaluate the existing evidence.

It is also worth noting that both drugs were developed to treat infections from parasitic worms. Even in the absence of sufficient evidence, current studies are exploring the effects of both of these drugs on cancer therapy.

However, neither of these drugs is approved for use in cancer treatment. It is very important that you analyze the current scientific research before prioritizing either of these drugs.

What Is Mebendazole vs Fenbendazole?

 Mebendazole vs Fenbendazole are both parasitic medications that come from a class of drugs called benzimidazoles.

Fenbendazole is predominantly used in veterinary medicine. Even in this case, fenbendazole is not used to treat cancer in humans.

Mebendazole is also safe for humans and is now used to treat a variety of infections from intestinal worms in humans. It also has a long history of being a safe prescription for these infections.

While both drugs are similar in chemistry and are similarly used in the treatment of parasitic infections, their anti-cancer properties remain to be investigated.

Why has the cancer community shown interest in Mebendazole vs Fenbendazole

Since early 2020, the cancer community has shown great interest in both Fenbendazole and Mebendazole. There have been rapid developments regarding the cancer community’s interest in both of these drugs.

The initial interest in these drugs accelerated following several studies that hypothesized both Fenbendazole and Mebendazole might inhibit the proliferation of certain types of cancer cells.

Subsequently, several cancer patients who had been undergoing the gold standard chemotherapy and/or radiotherapy cancer protocols began posting their personal anecdotes online stating that they had been experiencing a sort of cancer remission while they were taking Fenbendazole in combination with the aforementioned treatments.

How do Mebendazole vs Fenbendazole work?

 Mebendazole vs Fenbendazole both disrupt structures called microtubules, which play an important role in the division of cells.

With respect to parasites, Mebendazole vs Fenbendazole inhibit the absorption of nutrients to the parasites, thereby leading to the death of the parasites.

Cancer cells are also dependent on the microtubules that aid in their growth and division. Under certain experimental conditions, laboratory studies have shown that Fenbendazole and Mebendazole may interact with microtubules in cancer cells and may aid in slowing the growth of cancer cells and/or inducing the death of the cancer cells.

It has been noted that there may be other effects of these medications, such as affecting the metabolism of glucose within cancer cells, as well as the disruption of certain cellular pathways that may be involved in the proliferation of cancer.

Mebendazole vs Fenbendazole: Key Differences

Fenbendazole is mainly a vet drug and has not received approval as a human drug in many countries. Mebendazole is a human drug, and its safety profile is well defined for the approved indications of treatment of parasitic infections.

Mebendazole is extensively studied in human cancer research compared to fenbendazole since mebendazole is an already approved human drug.

Fenbendazole has gained attention on the internet due to patient testimonials, while the evidence-based medicine for the drug is lacking. Both are being researched, but neither is used in routinely prescribed oncology.

What the Research Says About Fenbendazole For Cancer

It has been shown that fenbendazole has the potential to inhibit the propagation of a limited number of cancer cell lines. This has also been observed in research conducted on animals.

Unfortunately, the number of high standard clinical trials has been very limited. Because of this, there is no way for medical professionals to know whether fenbendazole even works, what an appropriate dose would be, or if the possible negative effects of the drug could be justified by its benefits.

Fenbendazole is not a recommended drug for the treatment of cancer at this time.

What the Research Says About Mebendazole For Cancer.

Mebendazole has been studied more than fenbendazole since it is an already approved drug for humans.

Research on the activity of mebendazole has been conducted with various cancer cell lines including, but not limited to, brain cancer, colon cancer, lung cancer, breast cancer and melanoma cancer cells.

Some preliminary studies have examined the combination of mebendazole and conventional therapies for cancer. These studies have had modest success, although generally, the studies have had small sample sizes.

Mebendazole may find its place in the future of cancer therapies. More studies, specifically larger clinical studies, will be necessary to bring mebendazole to the forefront of cancer treatment.

Is Fenbendazole More Effective than Mebendazole for Cancer?

Currently, there are no studies to support that fenbendazole is a better choice than mebendazole when treating cancer.

Because of the difference in study design, laboratory techniques, and the variety of cancer studied, it is difficult to compare the available studies directly.

Fenbendazole is primarily supported by laboratory studies and anecdotal evidence, while mebendazole has more documented studies involving humans.

Until there are better-designed clinical studies to evaluate the two medications, the efficacy of both will remain unknown.

Mebendazole vs Fenbendazole Benefits

The low cost of mebendazole and fenbendazole, compared to other cancer treatments on the market today, combined with the fact that their chemistry is well-known, makes both medications good candidates to repurpose.

Animal and laboratory studies suggest that both medications can impact the rate of cancer cell proliferation.

Of course, there are some barriers to using both medications.

The current studies involving mebendazole and fenbendazole have primarily been animal and laboratory studies, rather than large studies with human participants.

Additionally, researchers have no way of knowing if any given cancer would respond to treatment with either medication, what the optimal dosing of either medication would be, how long treatment would be required, or if either medication would result in a meaningful increase in survival.

The lack of proof of the efficacy and safety of both medications leaves the use in cancer treatment entirely investigational.

Side Effects and Safety Considerations

Fenbendazole and mebendazole may cause side effects like any other drugs.

Mebendazole side effects are usually mild and indicate that it is well tolerated. They are:

• Nausea
• Pain in the abdomen
• Diarrhea
• Headache
• Mild rash

Safety studies for fenbendazole in humans have not been conducted. There are no potential side effects caused by oral fenbendazole in humans that have been established. There are many anecdotal reports regarding the potential of fenbendazole in humans.

There is the potential for serious side effects caused by oral fenbendazole. Veterinary medicines are for animals and are subject to very different regulations, standards, and manufacturing practices.

Patients undergoing chemotherapy should not self-prescribe or combine other drugs, including fenbendazole or mebendazole, without the guidance of their doctor.

Can Mebendazole vs Fenbendazole Be Used With Cancer Treatment?

Fenbendazole and mebendazole should not be used with cancer drugs without the guidance of an oncologist.

In combination, several drugs can potentially interact with cancer treatment, worsen liver function, and increase the side effect profile of the cancer therapy. This also applies to the most benign looking over-the-counter and herbal preparations.

The safest approach is to discuss any and all potential drug combinations with your medical doctor.

Mebendazole vs Fenbendazole to Treat Cancer?

If you or someone you know has been diagnosed with cancer, it is natural to be on the lookout for treatment options.

Although research on fenbendazole and mebendazole is ongoing and encouraging, neither drug has been proven to cure or treat human cancer effectively.

Choosing to replace conventional cancer therapy with either of these drugs may only serve to delay the use of treatments known to be effective in improving survival.

If you are seriously thinking about the use of either of these drugs, your best option is to discuss them with your oncologist. Your oncologist will be able to put the research into the proper context and evaluate the drugs in the proper context so that you can make a decision that is truly informed.

Bottom Line

Fenbendazole and mebendazole are antiparasitic drugs that have generated interest and buzz based on early research and the potential for anti-cancer properties.

Although laboratory studies have generated interest, and studies are ongoing, neither drug is sanctioned as a conventional cancer treatment, and the research to support either drug as a safe and effective cancer treatment is lacking.

Your best option is to use the treatment that your oncologist has recommended while being open to the research. Prior to these studies being completed, it is uncertain if these drugs can be used in the field of cancer research.
