Researchers have discovered that a dewormer used to treat parasites in dogs may also kill cancer cells. They found that fenbendazole inhibits glucose uptake in cancer cells and can kill tumors without damaging healthy tissue.

The drug hasn’t been approved for treating cancer and must undergo clinical trials to prove it is safe and effective. But the claims have garnered significant attention on social media, including on TikTok.


Fenben is a broad-spectrum antiparasitic drug that is used to treat parasitic worms in animals. It has recently come into the spotlight because of a story about a man who used it to cure his cancer. The story has prompted many people to try it for themselves. Some have even been able to keep their cancer from coming back for a long time. However, there is not enough evidence that fenben will help everyone with their cancer.

The anthelmintic activity of fenbendazole is based on its binding to b-tubulin microtubule subunits and disrupting their polymerization. It has also been shown to have cytotoxic properties and inhibit cell growth. These properties make it a promising candidate for a chemotherapeutic agent. In addition, it has a high safety profile in humans, with few reported side effects.

In the laboratory, fenbendazole has been shown to reduce tumor size and suppress recurrence in a variety of animal models. It has also been shown to enhance the efficacy of other drugs, such as radiation, surgery, and berberine. It also has the potential to reactivate the p53 gene, which functions as a tumor suppressor.

It is important to work with an integrative healthcare professional before trying fenben for cancer. This person will take a complete medical history and review your lab reports to determine the best dosage for you. It will also be essential to determine the right schedule for fenbendazole.


Fenbendazole, also known as fenben, is an antihelmintic drug used to treat parasites and worms in dogs and cats (commonly sold under the brand names Pancur and Safe-Guard). It has recently come into the spotlight because of an anecdotal story about a man named Joe Tippens who claimed that his cancer went into remission after taking fenbendazole. This claim sparked numerous social media posts and TikTok videos, but the FDA has warned that this drug isn’t effective in treating cancer.

The repurposing of medicines is an increasingly common practice in modern medicine. Many drugs that aren’t used to treat cancer can kill tumor cells by disrupting cellular mechanisms, such as depolymerizing MTs and inducing cell cycle arrest. However, it’s important to note that these drugs are not tested in randomized clinical trials, so they don’t necessarily have the same efficacy as other cancer treatments.

Several studies have investigated the efficacy of fenbendazole for humans with varying results. However, the most recent study found that fenbendazole inhibited the growth of human ovarian cancer cells and induced apoptosis in the tumors. The authors believe that the apoptosis effect is caused by a disruption of cellular metabolism and an inhibition of glucose uptake in cancer cells. In addition, the apoptosis caused by fenbendazole was specific to tumor cells that were actively growing and did not affect normal tissues.

Side effects

Social media are popular platforms for disseminating complex medical information. However, this information can spread fast and misguide people. In this case, a patient with non-small cell lung cancer obtained information on the antitumor activity of fenbendazole online and self-administered it, leading to severe liver injury. This is a serious warning to all individuals not to take medical advice online.

A number of studies have reported that fenbendazole has in vitro and in vivo anticancer effects. This effect is attributed to its ability to disrupt the microtubule network and induce apoptosis in tumor cells. Additionally, fenbendazole also inhibits the uptake of glucose by tumor cells, starving them of their main source of energy.

The benzimidazole family of drugs has been used as an animal anthelmintic for many years. It is effective against tapeworms and hookworms, as well as roundworms and whipworms. It is also safe for humans who come into contact with the treated animal. It is absorbed by the digestive tract and is excreted mainly in feces, with a small amount of drug being secreted in urine. Salivation is the most common side effect.

In a study conducted in the laboratory, researchers found that fenbendazole had a moderate MT depolymerizing activity and exhibited antitumor effects in various cancer cell lines. It also disrupted proteasomal interference and induced apoptosis in tumor cells. It also interfered with the appearance of GLUT4 protein in cell membranes, thus impairing insulin-fueled glucose uptake. fenben for humans
