{Abstract}: In many developing nations like India, the majority of the labor force comprises farmers. Therefore, there is a raised frequency of farmer suicides using pesticides. Toxin-induced methemoglobinemia is otherwise called toxic methemoglobinemia. It is a hematologic disorder attributed to exposure to toxic oxidizing agents and is most commonly seen in cases of poisoning. Methemoglobinemia is a condition in which there is an altered state of hemoglobin, resulting in reduced oxygen delivery to tissues. This case report represents a case of methemoglobinemia with acute kidney injury and hypoxic brain injury seen in a 23-year-old male patient. He was a farmer by occupation and was admitted due to ingestion of a pesticide named HUNT with suicidal intentions. He has had no previous history of psychiatric or neurologic disorders. The patient initially presented with a pulse rate of 110/min and room air saturation of 98% when he was brought to the casualty out patient department (OPD). Unfortunately, it worsened over the next 24 h, after which there was a sudden drop in SpO2 to 78% with oxygen support. Upon further examination and assessment, he was diagnosed with methemoglobinemia, leading to complications such as acute kidney failure and cerebral edema. He was then treated with hemodialysis, methylene blue, and ascorbic acid with viable improvement. This led to his complete recovery after eight days of treatment and support.
