1. What Gaviscon Instants Oral Powder is and what is it used for

Gaviscon Instants Oral Powder forms a protective layer which floats above the contents of the stomach. This layer prevents stomach acid escaping from the stomach into the food pipe, thus relieving the burning feeling of heartburn and the feeling of discomfort in the throat and mouth. Heartburn may occur following meals (e.g. when eating fatty or spicy food) or during pregnancy or in patients with symptoms related to an inflammation in the wall of the food pipe (e.g. difficult and / or painful swallowing, mouth sores, vomiting).

Gaviscon Instants Oral Powder is used for the treatment of symptoms of gastro-oesophageal reflux such as acid regurgitation, heartburn and indigestion (related to reflux), for example following meals or during pregnancy, and in patients with symptoms related to oesophagitis.
