Gaviscon (alginates) (Sodium alginate with antacids (commonly sodium bicarbonate and calcium carbonate)) — Uses, Dosage, Side Effects & Safety

Drug class: Antacid and reflux suppressant

Overview

Gaviscon (alginates) is an over-the-counter medication used to relieve symptoms of heartburn, acid indigestion, and gastroesophageal reflux disease (GERD). It works by forming a protective barrier (or 'raft') on top of the stomach contents, which helps prevent stomach acid from flowing back into the esophagus and causing discomfort. This medication acts quickly, often within minutes, and provides symptomatic relief for mild to moderate reflux. It is suitable for adults and children (with age-specific formulations), and is often recommended for use after meals and at bedtime. Key points for patients: Gaviscon does not prevent acid production but physically blocks acid from rising. It is generally well-tolerated, but should not be used as a substitute for prescription medications in severe or persistent reflux. Always follow the dosing instructions and consult your healthcare provider if symptoms persist.
