Gaviscon Double Action Mixed Berry - 24 Tablets

Gaviscon Double Action Mixed Berry 24 Tablets are a dual action chewable antacid formulation designed to deliver fast and long-lasting relief from symptoms associated with excess stomach acid such as heartburn, acid reflux, acid regurgitation and indigestion. Each tablet uses a combination of sodium alginate, sodium bicarbonate and calcium carbonate to both neutralise stomach acid and form a protective barrier (“raft”) over stomach contents, helping to keep acid where it belongs and soothe irritation.

The mixed berry flavour makes these tablets a pleasant option for adults and children over 12, offering a convenient way to manage discomfort after meals or at bedtime without the need for water. These chewables are part of the trusted Gaviscon range, a leading over-the-counter brand for heartburn and indigestion relief in the UK.
