This medication is used to treat occasional heartburn, acid indigestion, sour stomach, and general stomach discomfort caused by excess stomach acid. It may also help with symptoms of gastroesophageal reflux disease (GERD) when used as directed.
Both aluminum hydroxide and magnesium hydroxide are bases that neutralize hydrochloric acid in the stomach, raising the pH and reducing acidity. Aluminum hydroxide provides a longer-lasting effect while magnesium hydroxide acts more quickly, and together they balance gastrointestinal side effects.
Take as directed on the label or by your healthcare provider, typically after meals and at bedtime. May interact with other medications by affecting their absorption, so spacing doses is recommended. Those with kidney disease, constipation, or on sodium-restricted diets should consult a doctor before use. Not intended for long-term daily use without medical supervision.
