Uses For thiabendazole

Thiabendazole belongs to the family of medicines called anthelmintics. Anthelmintics are medicines used in the treatment of worm infections.

Thiabendazole topical preparations are used to treat a skin disease called cutaneous larva migrans (creeping eruption). Cutaneous larva migrans is caused by dog and cat hookworm larvae. These larvae cause slowly moving burrows or tunnels in the skin. This may result in itching, redness, or inflammation around the end of the burrows or tunnels.

Thiabendazole is available only with your doctor's prescription.
