Sodium bicarbonate, also known as baking soda, is used to relieve heartburn, sour stomach, or acid indigestion by neutralizing excess stomach acid. When used for this purpose, it is said to belong to the group of medicines called antacids. It may be used to treat the symptoms of a stomach or duodenal ulcers. Sodium bicarbonate is also used to make the blood and urine more alkaline in certain conditions.

Antacids should not be given to young children (up to 6 years of age) unless prescribed by their doctor. Since children cannot usually describe their symptoms very well, a doctor should check the child before giving this medicine. The child may have a condition that needs other treatment. If so, antacids will not help and may even cause unwanted effects or make the condition worse.
