Treats symptoms of gastroesophageal reflux disease (GERD), heartburn, acid indigestion, sour stomach, and conditions where stomach acid flows back into the esophagus causing discomfort.
Aluminum hydroxide and magnesium carbonate work as antacids by neutralizing stomach acid, while alginic acid reacts with sodium bicarbonate to form a protective foam or raft that floats on top of stomach contents, preventing acid from reaching the esophagus.
May interact with other medications by affecting their absorption; take doses at least 2 hours apart from other drugs. Use with caution in patients with kidney disease. Aluminum-containing antacids may cause constipation while magnesium-containing ones may cause diarrhea. Consult a healthcare provider before use during pregnancy or breastfeeding.
