Isobutyl nitrite is widely abused as a sexual stimulant and enhancer of discotheque dancing. Though the usual route of administration by inhalation has not resulted in any toxicologically verified deaths, there may be fatal toxic methemoglobinemia if the chemical is orally ingested. A second case of death following ingestion is discussed.

D008708	Methemoglobinemia	The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait).
