Drug Overview

Walgreens Ultra Strength Antacid is a chewable tablet that contains 1000 mg of calcium carbonate, which is a common ingredient used to relieve various stomach discomforts. This antacid is designed to help alleviate heartburn, acid indigestion, sour stomach, and upset stomach associated with these symptoms.

In addition to its effectiveness, Walgreens Ultra Strength Antacid is naturally flavored with peppermint and sweetened with stevia, making it a pleasant option for those seeking relief. Each package contains 72 gluten-free tablets, ensuring that you have plenty on hand when you need it.

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 soothing an upset stomach that may be associated with these issues.

Dosage and Administration

When you need relief from certain symptoms, adults and children aged 12 and older can chew 2 to 3 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 use the medication.

Always follow your doctor's advice regarding dosage and frequency. Taking the right amount at the right time is crucial for your safety and well-being.

You should not use it if the printed seal under the cap is torn or missing, as this could indicate that the product is compromised.

For your safety, avoid using the maximum dosage for more than 2 weeks unless your doctor has advised and is supervising you. Following these guidelines will help you use the medication effectively while minimizing the risk of misuse or dependence (a condition where your body becomes reliant on a substance).

Side Effects

It's important to be aware of potential side effects when taking medication. If you are currently on a prescription drug, be cautious as antacids may interact with certain medications, which could affect how well they work or increase the risk of side effects.
