Features
Gaviscon Double Action contains calcium carbonate and its unique formulation helps provide effective relief that is up to x2 longer than regular antacids. Gaviscon Double Action gets to work instantly in two different ways: 1. Through its antacid component, it neutralises excess stomach acid to help relieve discomfort. 2. Through the alginate (refined from seaweed), it forms a protective barrier over the stomach contents to soothe the burning sensation in your chest and help prevent reflux.
