Drug Overview

Children’s Antacid Chewables are chewable tablets that contain 400 mg of calcium carbonate, designed to help relieve common stomach discomforts. These include heartburn, acid indigestion, sour stomach, and upset stomach associated with these symptoms. With a pleasant bubble gum flavor, they are easy for children to take, providing a gentle solution for digestive relief.

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 an upset stomach that comes along 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 associated with it.
