Sodium bicarbonate is an antacid used to relieve heartburn and acid indigestion. Your doctor also may prescribe sodium bicarbonate to make your blood or urine less acidic in certain conditions.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Sodium bicarbonate comes as a tablet and powder to take by mouth. Sodium bicarbonate is taken one to four times a day, depending on the reason you take it. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sodium bicarbonate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you are using sodium bicarbonate as an antacid, it should be taken 1 to 2 hours after meals, with a full glass of water. If you are using sodium bicarbonate for another reason, it may be taken with or without food. Do not take sodium bicarbonate on an overly full stomach.
Dissolve sodium bicarbonate powder in at least 4 ounces (120 milliliters) of water. Measure powdered doses carefully using a measuring spoon.
Do not use sodium bicarbonate for longer than 2 weeks unless your doctor tells you to. If sodium bicarbonate does not improve your symptoms, call your doctor.
Do not give sodium bicarbonate to children under 12 years of age unless your doctor tells you to.
This medicine increases the amount of sodium in your body. If you are on a sodium-restricted diet, check with your doctor before taking sodium bicarbonate.
If your doctor has told you to take sodium bicarbonate on a certain schedule, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
