Methemoglobinemia is a rare but life-threatening clinical condition which has to be rapidly diagnosed and treated to have a favorable outcome. There are multiple known causes for Acquired Methemoglobinemia of which pesticides are rare and less reported. We report a case series of Methemoglobinemia due to pesticide consumption, who had a varying response to treatment modalities. We discuss about the various treatment options for methemoglobinemia from conventional Methylene blue to novel treatments like Exchange transfusion and Hyperbaric Oxygen Therapy. We found that monitoring Methemoglobin levels may be required for a longer duration due to the possibility of relapse. For refractory cases not improving with Methylene blue, exchange transfusion is an effective alternate treatment.
