Gaviscon Aniseed Advance Liquid has been specifically formulated for the treatment of gastro-oespophageal reflux. These symptoms include acid regurgitation, heartburn & indigestion which may occur following meals or during pregnancy, & in those who display symptoms of oesophagitis. This oral suspensionbelongs to a group of medicines called reflux suppressants which form a protective 'raft' on top of the stomach contents to prevent stomach acid from escaping into the oesophagus (food pipe) which causes pain & discomfort. As Gaviscon Advance works physically (rather than by entering the bloodstream) it is suitable for use in pregnancy too.
