Methylene blue is employed as a medication for the treatment of methemoglobinemia. This can arise from ingestion of certain , toxins, or broad beans. Normally, through the NADH or NADPH dependent methemoglobin reductaseenzymes, methemoglobin is reduced back to hemoglobin. When large amounts of methemoglobin occur secondary to toxins, methemoglobin reductases are overwhelmed.
