Mebendazole 100mg is an anthelmintic medicine commonly used in Australia for the treatment of intestinal worm infections such as pinworm, roundworm, whipworm, and hookworm. It works by preventing parasites from absorbing glucose, leading to their gradual death and elimination from the body. This medication is often prescribed for both adults and children and is typically taken as a single dose or short course depending on the infection type.
