Gaviscon Double Action 10ml Liquid Antacid Sachets provide fast and long-lasting relief from heartburn and indigestion. With their convenient mint flavor, these sachets deliver up to four hours of comfort. The dual-action formula combines two antacids-calcium carbonate and sodium bicarbonate-with alginate to work effectively in two ways: it neutralizes excess stomach acid to alleviate pain and discomfort, and it forms a protective barrier over stomach contents to soothe burning sensations in the chest. Gaviscon Double Action Liquid Sachets are ideal for treating symptoms of gastro-oesophageal reflux, including acid regurgitation, heartburn, and indigestion, which can occur after meals or during pregnancy, as well as for addressing symptoms of excess stomach acid (hyperacidity). Common symptoms alleviated include burning in the chest, bloating, and a sour taste in the mouth.
