Gaviscon (alginates/antacid) (Sodium alginate, sodium bicarbonate, calcium carbonate) — Uses, Dosage, Side Effects & Safety

Drug class: Antacid, Alginates (Gastroesophageal Reflux Suppressant)

Overview

Gaviscon (alginates/antacid) 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 acid from flowing back into the esophagus. The antacid components neutralize excess stomach acid, providing quick relief from discomfort. Gaviscon is commonly used after meals and at bedtime to manage symptoms such as burning in the chest, sour taste in the mouth, and regurgitation. It is suitable for adults and children over a certain age, but dosing may vary. Patients should be aware that while Gaviscon provides symptomatic relief, it does not treat the underlying causes of acid reflux or ulcers.
