AbstractCocaine is often "cut" with various additives to increase the profitability of the drug. One of the most common additives on today's market is levamisole, an anthelmintic medication used to destroy and expel parasitic worms in animals. The use of levamisole-contaminated cocaine can result in agranulocytosis and vasculitis (inflammation and constriction of small blood vessels). The resulting clotting and decrease in peripheral blood flow lead to cutaneous lesions, particularly on the ears, face, hands, and feet, and in severe cases can cause generalized tissue necrosis throughout the entire body. Treatment is generally supportive, and symptoms typically abate with complete cessation of cocaine use. However, symptoms may recur with subsequent cocaine use and, as this case illustrates, severe neutropenia and extensive vasculitis may lead to overwhelming sepsis and death.©2017 American Association of Critical-Care Nurses.
