Why is this medication prescribed?

Aluminum hydroxide and magnesium hydroxide are antacids used together to relieve heartburn, acid indigestion, and stomach upset. They may be used to treat these symptoms in patients with peptic ulcer, gastritis, esophagitis, hiatal hernia, or too much acid in the stomach (gastric hyperacidity). They combine with stomach acid and neutralize it. Aluminum hydroxide and magnesium hydroxide are available without a prescription.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Follow the directions on the package label or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
