RESUMO
Allopurinol is widely used drug for patients of hyperuricemia and gout. The few adverse drug reactions related to allopurinol are diarrhea, fever, hepatotoxicity, Steven Johnson Syndrome- Toxic Epidermal Necrolysis (SJS-TEN), congestive heart failure and renal failure. In this article we have described eleven cases to evaluate the causality, cause and management of this syndrome. In this study eleven retrospective cases were selected from the ADR reports. The full details of the cases were collected from Christian Medical College from the period of 2012 to 2016. Causality was established using Naranjo scale and classi?cation was done based on severity and resolution of ADR. It was observed that cases presented with mild to severe reactions of allopurinol, which is the suspected offending agent. Cases were resolved with supportive treatment while ?ve case had a prolong hospitalization and two cases had a life threatening drug reaction. Early detection and management of this severe form of systemic reaction is very important for better will be the prognosis.
