Gaviscon Advance Syrup is a specialized formulation designed to provide relief from heartburn and acid reflux. This 300ml bottle contains sodium alginate and potassium bicarbonate that work together to create a protective barrier on top of stomach contents, preventing acid reflux and providing long-lasting relief. The liquid formulation comes in a convenient 300ml bottle with a measuring cap for accurate dosing. When taken, the ingredients react with stomach acid to form a protective raft that floats on top of stomach contents, helping prevent reflux of acid into the esophagus. The medicine starts working quickly upon ingestion and can provide relief for several hours. As with all medications, it should be taken according to the recommended dosage instructions and stored at room temperature away from direct sunlight. Keep out of reach of children.
