Abstract

Increase in levels of methemoglobin is termed as methemoglobinemia which leads to organ level hypoxia. It can be congenital or acquired. In this case report we present a case of a middle-aged female with methemoglobinemia due to dapsone overdose and how immediate introduction of ascorbic acid, oxygen therapy and dapsone discontinuation cured the patient.
