Sodium Bicarbonate

Drug Information

Sodium bicarbonate (baking soda) is used as an antacid for short-term relief of stomach upset, to correct acidosis in kidney disorders, to make the urine alkaline during Reference bladder infections, and to minimize uric acid crystallization during Reference gout treatment. A prescription sodium bicarbonate product is given by injection to treat metabolic acidosis and some drug intoxications. Sodium bicarbonate is available as a nonprescription drug alone (sodium bicarbonate tablets) or in combination with other nonprescription drugs for short-term treatment of various conditions to treat fever and mild to moderate pain.

Reference Folic Acid

Folic acid is needed by the body to utilize Reference vitamin B12. Antacids, including sodium bicarbonate, inhibit folic acid absorption.¹ People taking antacids are advised to supplement with folic acid.
Reference Iron

In a study of nine healthy people, sodium bicarbonate administered with 10 mg of iron led to lower iron levels compared to iron administered alone.² This interaction may be avoided by taking sodium bicarbonate-containing products two hours before or after iron-containing supplements.
