摘要：Allopurinol is a drug used primarily to treat hyperuricemia and its complications including chronic gout. It causes DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) syndrome as a hypersensitivity reaction as a rare side effect of it. We report a case of 62 year old female presented with complaints of fever, jaundice, dyspnea, and generalized rash after 3 months of allopurinol treatment for hyperuricemia. She was diagnosed as a case of DRESS syndrome. Allopurinol treatment was stopped and steroid treatment was started. Patient was discharged after 4 weeks in a satisfactory condition.
