Drug Overview

Calcium Carbonate is an extra strength chewable tablet designed to provide fast relief from upset stomach, heartburn, acid indigestion, and sour stomach. With a pleasant tropical fruit flavor, these gluten-free tablets are easy to take and can help alleviate discomfort associated with these common digestive issues.

This medication works by neutralizing stomach acid, which can help soothe your stomach and reduce the symptoms of heartburn and indigestion. Each bottle contains 96 chewable tablets, making it a convenient option for managing occasional digestive discomfort.

Uses

If you're experiencing discomfort from heartburn, acid indigestion, or a sour stomach, this medication can help relieve those symptoms. It’s 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) associated with it. This makes it a safer option for those who may be concerned about such risks.

Dosage and Administration

If you are an adult or a child aged 12 years and older, you should chew 2 to 4 tablets completely whenever you experience symptoms, or follow your doctor's instructions. It's important not to swallow the tablets whole, as they need to be chewed to work effectively.

Be mindful that if your symptoms last longer than 2 weeks, you should consult with a doctor before continuing to take the medication. This ensures that you receive the appropriate care and guidance for your health.

What to Avoid

You can feel reassured that there are no specific contraindications, controlled substance classifications, or risks of abuse or misuse associated with this medication.

Additionally, using the maximum dosage for more than two weeks should only be done under a doctor's guidance.
