How should this medicine be used?
Tums comes as a tablet, chewable tablet, capsule, and liquid to take by mouth. It usually is 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 Tums 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 Tums as an antacid for more than 2 weeks without concerning your doctor first.

What special precautions should you follow?

  • 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. Your doctor will be able to tell you whether you can take antacids with these medications, and if so, whether you can do so at the same time, or take the medications at a different time. The time delay is usually at least 2 hours of taking an antacid.

  • Tell your doctor if you have or have ever had kidney disease or stomach conditions.

  • Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking calcium carbonate, call your doctor.

What side effects can this medication cause?
Although side effects from Tums are not common, they can occur. Tell your doctor if any of these symptoms are severe or do not go away:

  • upset stomach
  • vomiting
  • stomach pain
  • belching
  • constipation
  • dry mouth
  • increased urination
  • loss of appetite
  • metallic taste
