Gaviscon Double Action Sachets offer quick and long-lasting relief from heartburn and indigestion. With their simple mint flavor, these sachets provide 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, relieving pain and discomfort, and it forms a protective barrier over stomach contents, soothing burning sensations in the chest. Gaviscon Double Action Liquid Sachets are effective for treating gastro-oesophageal reflux symptoms such as acid regurgitation, heartburn, and indigestion that can occur after meals or during pregnancy, as well as symptoms of excess stomach acid (hyperacidity). Common symptoms relieved include burning in the chest, bloating, and a bad taste in the mouth.
