1. What is Gaviscon Duo and what is it used for

Gaviscon Duo is a combination of alginate and two acid-neutralizing agents (calcium carbonate and sodium hydrogen carbonate) and works through two mechanisms:

• Neutralizes excess stomach acid and relieves pain and discomfort;
• Creates a protective barrier over the stomach contents to soothe the burning sensation in the chest, which can last up to 4 hours. This medicine is used to treat symptoms of gastroesophageal reflux, such as heartburn, acid reflux, and indigestion (associated with reflux), for example, after meals or during pregnancy.
