Successful desensitization for treatment of an exfoliative dermatitis to allopurinol

Abstract

Allopurinol is widely used for chronic tophaceous gout as a uric acid lowering agent. Hypersensitivity to allopurinol occurrs in about 10% of patients, which limits the usage of allopurinol. The successful oral and intravenous desensitization of allopurinol has been reported worldwide since 1976. We recently experienced a 51-year-old male patient with gouty arthritis and hyperuricemia, who had previously experienced skin rash after allopurinol treatment. When allopurinol was retried, erythematous and foliative skin rash developed on entire body. Because allopurinol was essential in controlling hyperuricemia, the oral desensitization of allopurinol was tried. We report successful rapid oral allopurinol desensitization in the patient with chronic tophaceous gout, who exhibited exfoliative dermatitis as allopurinol hypersensitivity.
