fenbendazole for humans cancer is an anthelmintic, a drug that kills parasites in animals. Though anthelmintics have been studied as potential anti-cancer treatments, no peer-reviewed studies have found evidence that they can cure cancer in humans.
Posts and TikTok videos have been circulating on social media that claim that a man with cancer went into remission after taking fenbendazole. We take a look at the science behind this claim.
What is fenbendazole?
Fenbendazole is a benzimidazole with broad-spectrum anthelmintic activity. It is used to treat a variety of parasites including roundworms, hookworms, whipworms, lungworm, flukes, Giardia and certain types of tapeworm (Taenia genus). It also has antitumor activity in vivo.
In this study, we examined the effects of fenbendazole on EMT6 tumor growth and radiation sensitivity in BALB/c mice. Intensive treatments of fenbendazole produced dose-response curves that were superimposed on the survival curves for radiation and docetaxel, indicating additive cytotoxicity.
While fenbendazole is not a chemotherapeutic agent, it has been found to prevent tumor cell proliferation by inhibiting mitotic spindles and inhibiting cell division. In addition, it may enhance the effectiveness of other agents such as irradiation. Although anthelmintics are not currently listed as cancer treatments, there are indications that animal anthelmintics could be developed into viable human drugs. However, no peer-reviewed studies have confirmed that they can cure cancer. Research into these medications is ongoing.
How does fenbendazole work?
Fenbendazole was initially developed as a parasite treatment for animals, mainly dogs. The drug works very well to kill parasites and has a low level of toxicity. Animal research has also found that fenbendazole inhibits tumor growth in mice.
In experiments using cell cultures, fenbendazole caused a dose-dependent reduction in the number of viable cells, with a steep decrease at lower drug concentrations and a plateau at higher concentrations. The drug interferes with glucose metabolism, starving cancer cells of the fuel they need to grow and multiply.
In addition, fenbendazole is able to stabilize the p53 protein in cancer cells, allowing it to effectively destroy them. These effects, combined with the fact that fenbendazole inhibits cellular respiration and mitochondrial activity, make it a very effective cancer treatment. As a result, fenbendazole is often used in combination with other natural remedies to fight cancer. The Joe Tippens protocol recommends taking 222 mg of fenbendazole every day, seven days a week, with food.
What are the side effects of fenbendazole?
Fenbendazole is a very safe drug at appropriate dosages for most animals and humans. It is a broad-spectrum anthelmintic that effectively treats giardia, roundworms (including hookworms and whipworms), hookworms of the Taenia genus of tapeworms, pinworms, aelurostrongylus, and strongyloides. It does not, however, treat heartworms.
It has been shown to inhibit the growth of cancer cells by disrupting microtubules that provide structure for all cell types including normal body cells and cancer cells. It also interferes with glucose metabolism, starving cancer cells of their energy source and promoting their death both in lab settings and in living patients.
Studies have also shown that fenbendazole suppresses tumors in animal models when combined with radiosensitizers or taxanes. It is also effective as a single therapy. In a mouse model of allergic airway disease induced by ovalbumin, fenbendazole reduced the number of eosinophils in bronchoalveolar lavage fluid.
Is fenbendazole safe?
Fenbendazole has a long track record of safe use and is well tolerated even when administered in high doses for extended periods. It has also shown promising anti-cancer activity in lab experiments. However, it is still a long way from laboratory discovery to becoming a cure for cancer in humans.
The growth of EMT6 tumors in BALB/cRw mice was compared between groups randomized to receive either three daily i.p. injections of fenbendazole alone, irradiation with 10 Gy, or fenbendazole plus x-rays. The results showed that neither fenbendazole alone nor irradiation significantly affected the growth of the tumors, but that the combination of both drugs remarkably reduced the number of survivors.
Veterinary veterinarians prescribe fenbendazole (also known as Panacur) to treat giardia, roundworms, hookworms, lungworms, whipworms, and the tapeworm genus Taenia. Like other anthelmintic medications, it is effective when given once daily for several days in cats and dogs. Typically, veterinarians will recommend testing a fecal sample 2-4 weeks after finishing the medication to ensure it was effective.
