What is Gaviscon Double Action Tablets?
Gaviscon Double Action Tablets are chewable mint-flavoured tablets for heartburn and indigestion, including symptoms linked to acid reflux. They offer relief from both excess acid and the burning sensation of reflux.
How does it help?
The alginate forms a protective raft that floats on top of the stomach contents to help stop acid rising into the gullet, while the antacids (sodium bicarbonate and calcium carbonate) neutralise excess stomach acid.
Key benefits
- Relieves heartburn and acid indigestion
- Alginate raft helps block acid reflux
- Antacids neutralise excess stomach acid
- Convenient chewable tablets to take anywhere
- Mint flavour
