Overview
Gaviscon Double Action Chewable Tablets are specially formulated to tackle the causes and symptoms of acid reflux and indigestion. The tablets work in two ways: they neutralise excess stomach acid to reduce irritation, while also forming a protective “raft” that floats on top of stomach contents, helping to prevent acid from flowing back into the oesophagus.
The chewable format allows for quick absorption and easy use without water, making them ideal after meals, at bedtime, or whenever symptoms strike. With a refreshing mint flavour, Gaviscon Double Action offers reliable relief that fits easily into daily life.
