Fenbendazole is a benzimidazole class of antiparasitic drugs that targets a range of intestinal parasites, such as roundworms, hookworms, whipworms, and tapeworms. It works by inhibiting the parasites’ ability to absorb glucose, which leads to their death. Initially developed for veterinary use, Fenbendazole has since garnered attention for potential use in humans, especially in off-label treatments.
