Description
What is Gaviscon Advance Liquid?
Gaviscon Advance Liquid is an oral suspension used to relieve the symptoms of gastro-oesophageal reflux, acid regurgitation and heartburn. It contains a high-strength sodium alginate formula which reacts with stomach acid to form a protective gel “raft”. This raft floats on top of the stomach contents, reducing acid reflux into the oesophagus.
As a result, it provides long-lasting relief, particularly after meals and at night.
Who is it suitable for?
- Adults and children over 12 years
- Individuals experiencing acid reflux, heartburn or regurgitation
- Patients diagnosed with gastro-oesophageal reflux disease (GORD)
If unsure whether reflux symptoms require medical review, speak to a pharmacist.
