Levamisole is an antihelminthic drug with immunomod- ulatory properties. Recent estimates suggest the majority of the cocaine in the United States is adulterated with levamisole. Le- vamisole-induced necrosis syndrome (LINES) is characterized by vasculitis, neutropenia, and purpura that progresses to skin necro- sis. ⋯ Patients with LINES can have a wide variety of outcomes; thus, this syndrome must be aggressively managed. Psychotherapy should also be utilized to help patients with further cocaine use. Levamisole-induced necrosis syndrome incidence is expected to in- crease, and all providers should be aware of this patient population.
