Mebendazole 100mg in Australia is an anthelmintic medication commonly used to treat intestinal worm infections such as pinworm, roundworm, and whipworm. It works by preventing the parasites from absorbing glucose, leading to their gradual elimination from the body. In Australia, mebendazole is typically available in tablet or chewable form and is often used for both adults and children under medical guidance. The dosage depends on the type of infection and patient condition. While generally well tolerated, some users may experience mild side effects like stomach pain or nausea.
