Gaviscon provides long lasting relief for heartburn and indigestion.

How Does Gaviscon Work? Gaviscon forms a 'raft' over the stomach contents which helps prevent acid coming back up into the esophagus (food pipe). The raft acts as a strong physical barrier and helps keep all the components of the stomach contents in the stomach where they work, not letting them seep back up into the oesophagus where they hurt It works in 3 minutes to provide long lasting relief of up to 4 hours!
