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 gastrooesophageal reflux such as acid regurgitation, heartburn and indigestion (related to
