Gaviscon Advance Liquid Aniseed - 250ml

Gaviscon Advance Liquid Aniseed 250 ml is an extra-strength oral antacid suspension formulated to provide fast and long-lasting relief from troublesome symptoms associated with excess stomach acid, including heartburn, acid reflux, acid regurgitation and indigestion. Its advanced formulation contains a high concentration of sodium alginate and potassium hydrogen carbonate, which work together to form a protective barrier (or “raft”) on top of stomach contents, helping prevent acid rising into the oesophagus and soothing irritation at the root of discomfort.

The pleasant aniseed flavour makes this liquid a good alternative for those who prefer non-mint tastes. Gaviscon Advance is widely stocked in UK pharmacies and recommended for occasional use to rapidly ease symptoms and support digestive comfort.
