What this product is and what is it used for?
Gaviscon Extra Strength 500 Lemon Tablets belong to a group of medicines called
“reflux suppressants”, which form a protective layer on top of the stomach contents to
prevent stomach acid escaping from the stomach where it works into the food pipe
causing pain and discomfort.
They are 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.
