Fenbendazole

Fenbendazole is a broad-spectrum antiparasitic medication commonly used in veterinary medicine to treat intestinal worms in dogs, cats, horses, and livestock. It effectively targets roundworms, hookworms, whipworms, some tapeworms, and even Giardia. Fenbendazole works by blocking the parasites' ability to absorb glucose, eventually starving and killing them. It's typically given once daily for several days, depending on the type of infection. Though it's for animal use, some off-label interest exists in human medicine, especially for potential anti-cancer effects, though not officially approved.
