Drug Overview

TUMS is an antacid that helps relieve discomfort from heartburn, acid indigestion, sour stomach, and upset stomach associated with these symptoms. It contains calcium carbonate, which works quickly to neutralize stomach acid, providing fast relief when you need it.

Available in assorted fruit flavors, TUMS comes in a convenient package of 72 chewable tablets, making it easy to take whenever you experience digestive discomfort. With its ultra strength formulation, TUMS is designed to go to work in seconds, helping you feel better quickly.

Uses

If you're experiencing discomfort from heartburn, acid indigestion, or a sour stomach, this medication can help relieve those symptoms. It is also effective for soothing an upset stomach that may be associated with these issues.

You can feel confident using this medication, as there are no known teratogenic effects (which means it doesn't cause birth defects) or nonteratogenic effects reported. This makes it a safe option for managing your digestive discomfort.

Dosage and Administration

When you need relief from certain symptoms, adults and children aged 12 and older can chew 2 to 3 tablets as needed. It's important to chew or crush the tablets completely before swallowing them to ensure they work effectively.
