Breaking-Out Bad: A Case of Levamisole-Induced Vasculitis

The addition of harmful adulterants to cocaine has become widespread in recent years and constitutes a novel etiological agent for disease. One agent in particular, the veterinary anthelmintic “levamisole,” has been increasingly used, owing to its potentiating effects of cocaine and its ability to pass crude methods of detection. Levamisole has been shown to cause a vasculitic syndrome of retiform purpura and skin necrosis, as well as leukopenia and autoantibody formation.
