Treatment of trichinosis with mebendazole.

Prolonged oral high-dose mebendazole therapy provided an effective anthelmintic regimen for trichinosis unresponsive to steroid therapy in one patient. Side effects were limited to a Herxheimer-like reaction. Serum mebendazole levels documented gastrointestinal absorption. Repeat muscle biopsies and fluorescein angiography substantiated objective improvement.
