Hepatitis associated with allopurinol.
When adverse reactions occur, it is important to identify the etiologic drug. We describe a case of hepatitis associated with allopurinol. A 66-year-old female was admitted for rehabilitation of a cerebral hemorrhage on September 11, 1981. Allopurinol, clofibrate, and baclofen were administered. Severe hepatitis developed on November 13. The clinical laboratory data returned to normal on November 30. Challenge tests were conducted on clofibrate, allopurinol, and baclofen. The challenge test was positive after the administration of allopurinol. Allopurinol hepatitis is most likely a hypersensitivity reaction, as is suggested by the symptoms of eosinophilia and rash. Renal dysfunction may predispose one to develop hepatitis associated with allopurinol.
