mebendazole over the counter is an antiparasitic medication commonly used to treat a variety of intestinal worm infections. It is effective against pinworms (Enterobius vermicularis), roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura), and hookworms. Mebendazole works by inhibiting the parasites’ ability to absorb glucose, leading to their eventual death and elimination from the body. It is often prescribed as a single dose or a short course, depending on the type of infection. The medication is considered safe for both adults and children over two years old, with minimal side effects when taken as directed by a healthcare provider.
