Jul 15, 2023 · Sodium nitrite is a powder used in some foods and other products. It can be deadly if too much is taken by mistake or on purpose. Learn the symptoms, causes, safety measures, and treatment of sodium nitrite poisoning from WebMD.
Clinical manifestations can include cyanosis, hypoxia, altered consciousness, dysrhythmias, and death. The majority of reports on sodium nitrite poisonings have been the result of unintentional exposures. We report a case of an intentional fatal overdose of sodium nitrite.

Toxicity. Sodium nitrite is toxic. The LD 50 in rats is 180 mg/kg and in humans LD Lo is 71 mg/kg. The mechanism by which sodium nitrite causes death is methemoglobinemia. The oftentimes severe methemoglobinemia found in sodium nitrite poisoning cases results in systemic hypoxia, metabolic acidosis, and cyanosis.

The most sensitive and widely-recognized toxic effect of nitrate and nitrite is that of nitrite-induced methemoglobinemia in which nitrite (ingested as nitrite, formed via bacterial reduction of ingested nitrate, and/or produced as an endogenous product of the nitric oxide oxidation) reacts with ferrous (Fe 2+) hemoglobin (which transports ...
Abstract. Introduction: Sodium nitrite is an oxidizing agent capable of producing profound methemoglobinemia. Large quantities of sodium nitrite can be purchased online, and recent literature has identified several cases of intentional self-poisoning, including multiple cases of mortality.
