Mebendazole 100mg is an anthelmintic medicine widely used to treat intestinal worm infections such as pinworm, roundworm, whipworm, and hookworm. It works by blocking the parasites’ ability to absorb glucose, gradually causing them to lose energy and die, allowing the body to naturally eliminate them. In Australia, it is commonly prescribed or recommended for parasitic infections, especially in children and adults with confirmed worm infestations.
