Over the past few months, posts on Facebook and TikTok have gained traction claiming that a dog deworming medicine cured cancer in people. The stories are based on an anecdotal account of Joe Tippens, a man who claims that his lung cancer went into remission after he started taking fenbendazole (methyl [5-(phenylsulfanyl)-1H-benzimidazol-2-yl] carbamate), which is commonly prescribed as a parasitic medication.
Fenbendazole is a broad spectrum anthelmintic drug that is used to treat several parasites in humans and animals. The mechanism of action involves binding to beta-tubulin and disrupting its formation, thereby destabilizing microtubules and inhibiting cellular activities. Studies on the effect of fenbendazole on cancer cells have shown that it has the potential to exert antitumor activity in human non-small cell lung cancer cells and mouse xenografts.
In these experiments, fenbendazole interfered with the ability of cancer cells to take in glucose for their energy needs, which caused them to die. These results are promising but further research is needed to establish if this compound can act as a treatment for cancer in humans.
A healthcare professional can assess whether a patient may benefit from fenbendazole and can recommend the right dosage. They will take a detailed medical history and review the patient’s current medications to ensure that it is safe for them to begin the treatment. They can also develop a protocol to help maximize the benefits and minimize any negative side effects. It is important to note that there is no evidence that fenbendazole can cure cancer in any way, as conventional treatments are generally the only way to achieve complete remission. fenbendazole cancer treatment
