Mebendazole 100mg Australia is an antiparasitic medicine used to treat intestinal worm infections, particularly threadworm (pinworm). In Australia, 100 mg mebendazole tablets are available through pharmacies and are listed for treating threadworm, while treatment of roundworm, hookworm, or whipworm may require medical advice. Mebendazole works by interfering with the worms’ ability to survive and grow.
