It belongs to a group of medicines called \'reflux suppressants\'. Gaviscon Original Peppermint contains three active ingredients which work together as reflux suppressants.

Heartburn is a common symptom that lots of people deal with at one point or another, and it’s caused by acid reflux. Acid reflux is when your stomach acid moves up from your stomach through your food pipe or oesophagus, irritating its delicate lining and causing annoying symptoms like heartburn. Some of the other symptoms you may experience if you have acid reflux include: A sore throat, bad breath, an unpleasant taste in the mouth, bloating and feeling sick.
