Maalox is an antacid containing aluminium hydroxide and magnesium hydroxide. These help neutralize or reduce stomach acid (antacid). Some formulas also contain simethicone, which helps treat the gassy, bloated feeling (antigas). Maalox has been used in relief of indigestion, heartburn, gastroesophageal reflux disease (GERD), and stomach or duodenal ulcers.

    How should this medicine be used?
    This medication comes as a chewable tablet and liquid to take by mouth. Chew tablets thoroughly; do not swallow them whole. Drink a full glass of water after taking the tablets. Shake the oral liquid well before each use to mix the medicine evenly. The liquid may be mixed with water or milk.

    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. Take aluminum hydroxide and magnesium hydroxide antacids exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Do not take antacids for more than 1-2 weeks unless prescribed by your doctor.

    What special precautions should you follow?

    • Tell your doctor and pharmacist if you are allergic to calcium carbonate or any other drugs.
    • Tell your doctor and pharmacist what prescription and nonprescription medications you are taking. Your doctor will be able to tell you whether you can take antacids with these medications, and if so, whether you can do so at the same time, or take the medications at a different time. The time delay is usually at least 2 hours of taking an antacid.
    • Tell your doctor if you have or have ever had kidney disease or stomach conditions.
    • Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking calcium carbonate, call your doctor.
