Sodium nitrite is used as a medication together with sodium thiosulfate to treat cyanide poisoning.[2] It is only recommended in severe cases of cyanide poisoning.[3] In those who have both cyanide poisoning and carbon monoxide poisoning sodium thiosulfate by itself is usually recommended.[4] It is given by slow injection into a vein.[2]
Side effects can include low blood pressure, headache, shortness of breath, loss of consciousness, and vomiting.[2] Greater care should be taken in people with underlying heart disease.[2] People's levels of methemoglobin should be regularly checked during treatment.[2] While not well studied during pregnancy, there is some evidence of potential harm to the baby.[5] Sodium nitrite is believed to work by creating methemoglobin that then binds with cyanide and thus removes it from the mitochondria.[5]
Sodium nitrite came into medical use in the 1920s and 1930s.[6][7] It is on the World Health Organization's List of Essential Medicines.[8] The cost in the United States together with sodium thiosulfate is about US$110.[9]
