Mebendazole over the counter in Australia is an antiparasitic medicine used to treat intestinal worm infections such as pinworm, roundworm, and whipworm. In Australia, access to mebendazole may be limited, and it is often supplied through pharmacies with pharmacist advice rather than open shelf purchase. It works by stopping worms from absorbing nutrients, helping clear the infection from the body effectively. Dosage depends on age and infection type, and household treatment may be needed for pinworm control. It is generally well tolerated but should be used cautiously during pregnancy or liver conditions. Always follow pharmacist or healthcare advice before using this medication for safe and effective treatment.
