WHY is this medicine prescribed?
Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. Calcium is needed by the body for healthy bones, muscles, nervous system, and heart. Calcium carbonate also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach. It is available with or without a prescription.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
HOW should this medicine be used?
Calcium carbonate comes as a tablet, chewable tablet, capsule, and liquid to take by mouth. It is usually taken three or four times a day. Follow the directions on your prescription or package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take calcium carbonate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. When using this medicine as a dietary supplement, take it with food or following meals.
Chewable tablets should be chewed thoroughly before being swallowed; do not swallow them whole. Drink a full glass of water after taking either the regular or chewable tablets or capsules. Some liquid forms of calcium carbonate must be shaken well before use.
Do not take calcium carbonate as an antacid for more than 2 weeks unless your doctor tells you to.
What SPECIAL PRECAUTIONS should I follow?
Before taking calcium carbonate,
- tell your doctor and pharmacist if you are allergic to calcium carbonate or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially digoxin (Lanoxin), etidronate (Didronel), phenytoin (Dilantin), tetracycline (Sumycin), and vitamins.
