Fenbendazole 150 mg Tablet is an antiparasitic medication originally developed for veterinary use but increasingly discussed for its potential benefits in humans. It belongs to the benzimidazole class of drugs and works by disrupting the energy metabolism of parasitic organisms.

Specifically, Fenbendazole binds to the protein tubulin, which is essential for forming microtubules—structures that parasites use for nutrient absorption, cell division, and mobility. By preventing microtubule formation, Fenbendazole stops the parasites from absorbing glucose, effectively starving them to death. This mechanism makes it effective against a range of intestinal parasites, including roundworms, hookworms, whipworms, and Giardia.

The 150 mg dosage is considered a low-to-moderate dose, often used as part of a short-term treatment regimen, usually taken over 3 to 5 days. Some individuals, under medical supervision, explore Fenbendazole for off-label uses such as cancer support, due to its reported effects on disrupting cancer cell growth—but more clinical research is needed in that area.
