This medication treats symptoms associated with excess stomach acid, including heartburn, acid indigestion, sour stomach, and upset stomach, particularly when these conditions are accompanied by mild to moderate pain, headache, or fever.
The antacid components (calcium carbonate, magnesium carbonate, and magnesium oxide) neutralize stomach acid to provide relief from acid-related discomfort. Acetaminophen works centrally in the nervous system to reduce pain perception and fever.
Do not exceed the recommended dose, as this medication contains acetaminophen which can cause liver damage in high doses. Antacids may interfere with absorption of other medications—take other drugs at least 2 hours apart. Those with kidney problems, liver disease, or on a magnesium-restricted diet should consult a healthcare provider before use. Not intended for severe stomach pain.
