Gaviscon Advance Oral Suspension 300ml is a trusted solution that quickly and effectively relieves digestive problems like heartburn and indigestion. It contains sodium alginate, calcium carbonate, and sodium bicarbonate that work together. This mixture forms a protective barrier in the stomach, stopping acid from flowing up into the food pipe and causing discomfort. The liquid is easy to swallow and provides fast relief from common symptoms such as heartburn, acid reflux, and bloating. It can be used by both adults and children aged 12 and older. The medicine also helps people with a long-term condition called gastroesophageal reflux disease (GERD), which causes frequent acid reflux.
