When Joe Tippens was diagnosed with late-stage lung cancer and told he only had months to live, he refused to accept his fate. He contacted MD Anderson and was put on a trial of chemotherapy, which shrunk a tumor in his lungs. But his miracle treatment, which he credits to dog dewormer for cancer, has left scientists scratching their heads and people around the world raising their eyebrows.
Several Facebook posts and TikTok videos have claimed that dog dewormer, or fenbendazole (also known by the brand names Panacure, Safe Guard and Pro Sense), can treat cancer in humans. Some peer-reviewed studies have found potential in fenbendazole treating human cancer, but further research is needed.
The fenbendazole claim has gained traction because of the story of Joe Tippens, an Oklahoma man who claims his cancer went into remission after he started taking fenbendazole on a veterinarian’s recommendation. He followed a regimen that included the drug and CBD oil, curcumin, vitamin E and other supplements.
The claims have been met with skepticism by medical experts and the federal government, which tells PolitiFact that it has no evidence of the anticancer effects of fenbendazole or any other animal medicine in humans. But some people are continuing to buy fenbendazole online and following dosage advice from unproven sources on social networking sites like TikTok. This is problematic because patients who self-administer veterinary drugs while participating in a clinical trial could alter the results of that trial, potentially costing them time and money and possibly putting their lives at risk. dog dewormer for cancer
