These tablets come in a pleasant assorted fruit flavor, making them a convenient option for those seeking quick relief from occasional stomach upset. With a total of 150 chewable tablets in each package, they are a practical choice for managing digestive discomfort at home or on the go.

Uses

If you're experiencing discomfort from heartburn, sour stomach, or acid indigestion, this medication can help relieve those symptoms. It’s 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.

Dosage and Administration

When you need relief from certain symptoms, adults and children aged 12 and older can chew 2 to 4 tablets completely as the symptoms occur, or follow your doctor's instructions. It's important not to swallow the tablets whole, as they need to be chewed to work effectively.
