ABSTRACT

Dapsone is a commonly prescribed leprostatic agent for the treatment of patients with leprosy, malaria, and a variety of skin diseases. Methemoglobinemia, a potentially life threatening when the oxygen carrying capacity of blood in the body tissues is reduced, is a known adverse effect of dapsone use. We report a case of dapsone induced Methemoglobinemia observed in the Emergency Service of Hospital General, Centro Médico Nacional la Raza, in a patient with vitiligo treated with dapsone and taking this for purposes of attempting suicide. The pathophysiological mechanisms, diagnosis, and treatment of dapsone-induced methemoglobinemia will be discussed.
