How Gaviscon Double Strength Works

Our Double Strength formula is designed to relieve the pain and discomfort of heartburn and indigestion. The sodium alginate in Gaviscon Double Strength acts as a ‘raft’ that forms over the contents of your stomach to help relieve reflux.

It’s called Gaviscon Double Strength for a reason, as it contains double the concentration of sodium alginate compared with Gaviscon Original so you only need to take half as much.

For fast-acting relief of heartburn and indigestion, Gaviscon Double Strength will take care of you.

Always read the label. Follow the directions for use. If symptoms persist, talk to your health professional.
