What are Gaviscon Advance Mint Chewable Tablets?

Gaviscon Advance Mint Chewable Tablets are used to relieve heartburn, acid reflux and indigestion caused by reflux of stomach contents. They provide long-lasting relief by forming a protective barrier on top of the stomach contents to help prevent acid rising into the oesophagus.

What are Gaviscon Advance Mint Chewable Tablets used for?

These tablets are used for the relief of:

  • Heartburn and acid reflux
  • Indigestion after meals or during pregnancy
  • Symptoms of gastro-oesophageal reflux disease (GORD)
  • Discomfort caused by regurgitation of stomach acid

How do Gaviscon Advance Mint Chewable Tablets work?

The tablets contain sodium alginate, which reacts with stomach acid to form a protective gel or “raft” that floats on top of the stomach contents. This raft helps prevent acid from flowing back into the oesophagus. Potassium bicarbonate supports the raft-forming action.

Who are Gaviscon Advance Mint Chewable Tablets suitable for?

These tablets are suitable for adults and children over 12 years.
They may not be suitable if you:

  • Are allergic to sodium alginate, potassium bicarbonate, or any other ingredients
  • Are on a strict low-sodium or low-potassium diet
  • Have kidney or heart problems
  • Are under 12 years unless advised by a doctor

  2. Do not exceed 8 tablets in 24 hours.
