Intravenous sodium bicarbonate, also known as sodium hydrogen carbonate, is a medication primarily used to treat severe metabolic acidosis.[2] For this purpose it is generally only used when the pH is less than 7.1 and when the underlying cause is either diarrhea, vomiting, or the kidneys.[3] Other uses include high blood potassium, tricyclic antidepressant overdose, and cocaine toxicity as well as a number of other poisonings.[2][4][5] It is given by injection into a vein.[3]
Side effects may include low blood potassium, high blood sodium, and swelling.[2][5] It is not recommended for people with low blood calcium level.[6] Sodium bicarbonate is in the alkalinizing family of medications.[6] It works by increasing blood bicarbonate, which buffers excess hydrogen ion and raises blood pH.[6]
Commercial production of sodium bicarbonate began between 1791 and 1823.[7] Intravenous medical use began around the 1950s.[5] It is on the World Health Organization's List of Essential Medicines.[8] Sodium bicarbonate is available as a generic medication.[6]
