How to identify DRESS, drug reaction with eosinophilia and systemic symptoms?

Abstract

DRESS (drug reaction with eosinophilia and systemic symptoms) is a rare, severe multiorgan adverse drug reaction. Antiepileptic age's and antibiotics are the most frequently reported causative agents. Compared with other drug reactions, DRESS demonstrates a long latency period thus complicating recognition and diagnosis. DRESS is defined as presence of fever, skin eruption, hematologic abnormalities and systemic involvement, especially liver injury. Withdrawal of the culprit drug, commencement of systemic corticosteroid and supportive care are the mainstay of treatment. The majority of patients recover completely after drug withdrawal and appropriate therapy. Some patients suffer from chronic sequelae or even death.
