Drug Overview

Extra Strength Smooth Antacid Tablets are chewable tablets that contain 750 mg of calcium carbonate, which is a common ingredient used to relieve various stomach discomforts. You can take these tablets to help alleviate heartburn, sour stomach, acid indigestion, and upset stomach associated with these symptoms. They come in an assorted fruit flavor and are packaged in a convenient bottle of 60 tablets.

These antacid tablets work by neutralizing stomach acid, providing quick relief from discomfort. They are comparable to the active ingredient found in Extra Strength Tums® Smoothies™, although they are not manufactured or distributed by the same company.

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.

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 arise. It's important not to swallow the tablets whole, as they need to be chewed for proper effectiveness.

If your symptoms last longer than 2 weeks, you should consult with a doctor before continuing to take the medication. Remember, it's best to follow your doctor's advice regarding how often to take the tablets based on your specific situation.

What to Avoid

Always prioritize open communication with your doctor about any concerns or questions you may have regarding your treatment.

Side Effects

When using this product, it's important to be aware of potential side effects and interactions. You should consult with a doctor or pharmacist if you are taking any prescription medications, as antacids can interact with them.
