Contents of the pack and other information
1. What Gaviscon Fizzolve Oral Powder is and what is it used for.
Gaviscon Fizzolve 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 Fizzolve Oral Powder is used for the treatment of symptoms of gastrooesophageal 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.
