How does it work?
Sodium bicarbonate is a salt that breaks down in fluids, including blood and urine, to form sodium and bicarbonate. This breakdown makes the fluid alkaline, meaning it is able to neutralize acid. This ability to neutralize acid helps treat conditions related to high acidity in bodily fluids, such as indigestion, which is caused by too much acid in the stomach. 
Side Effects
Sodium bicarbonate is LIKELY SAFE when taken by mouth appropriately in the short-term and when used intravenously (by IV) and appropriately with proper medical supervision. Over-the-counter antacid products containing sodium bicarbonate are considered safe and effective by the U.S. Food and Drug Administration (FDA). The FDA suggests a maximum daily dosage of 200 mEq sodium and 200 mEq bicarbonate in people up to 60 years old , and maximum daily dosage of 100 mEq sodium and 100 mEq bicarbonate in people over 60 years old for up to 2 weeks.
