Mebendazole is an antiparasitic medicine used to treat various worm infections by preventing the worms from absorbing sugars that they need to survive, which helps to kill them over time.
This action, known as the mebendazole mechanism of action, makes it effective against several intestinal worms such as pinworms, roundworms, whipworms, and hookworms by killing them gradually through nutrient starvation.
