A Case of Dapsone Overdose Induced Methemoglobinemia

Abstract

Dapsone is a drug with potent anti-inflammatory and anti-parasitic activities, which waspreviously used almost exclusively for the treatment of leprosy. Dapson rarely induce oxidationof haemoglobin which overwhelms the activity of intrinsic red cell methaemoglobin reductaseresulting in significant methaemoglobinaemia. Methylene blue and hemodialysis are consideredas treatment options of metheamoglobinemia together with supportive treatment. Here in wepresent a case of methemoglobinemia due to intentional ingestion of 4 gr dapson
