Drug Overview

Extra Strength Antacid Tablets contain 750 mg of calcium carbonate, which is a medication that helps relieve symptoms such as heartburn, sour stomach, acid indigestion, and upset stomach. These chewable tablets are designed to provide fast relief from these common digestive discomforts, making them a convenient option for managing occasional stomach issues.

With a pleasant assorted berries flavor, these tablets are easy to take and are available in a pack of 250. They work similarly to the active ingredient found in Extra Strength Tums®, offering you a reliable choice for soothing your stomach when you need it most.

Uses

If you're experiencing discomfort from heartburn, sour stomach, or acid indigestion, this medication can help relieve those symptoms. It is also effective for upset stomachs that are 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 4 tablets completely as the symptoms occur. It's important not to swallow the tablets whole, as they need to be chewed to work effectively.

If your symptoms last longer than 2 weeks, you should consult a doctor before continuing to take the medication. Always follow your healthcare provider's advice for the best results.
