Gaviscon Advance Peppermint – Extra Strength Heartburn & Acid Reflux Relief

Gaviscon Advance Peppermint is specially formulated to provide powerful protection against the discomfort of heartburn, acid reflux, and indigestion. The extra-strength formula creates a strong protective barrier that helps keep stomach acid where it belongs – in your stomach – providing up to four hours of relief.

The fresh peppermint flavour makes it pleasant to take, while the smooth, soothing liquid works quickly to calm irritation and ease discomfort. Alternatively, you can also buy Gaviscon Advance with an aniseed flavour.

What is Gaviscon Advance Peppermint used for?

Gaviscon Advance Peppermint is designed to relieve and prevent symptoms caused by excess stomach acid, including:

  • Heartburn (acid reflux)
  • Indigestion (dyspepsia)
  • Discomfort after eating or during pregnancy
  • Acid regurgitation, particularly at night

How does Gaviscon Advance work?

Gaviscon Advance contains two active ingredients: sodium alginate and potassium bicarbonate. When swallowed, sodium alginate reacts with stomach acid to form a thick, protective layer on top of your stomach contents. This ‘raft’ acts as a physical barrier, preventing acid from rising into the oesophagus, while potassium bicarbonate helps neutralise excess acid.

Who can use it?

Most adults and children over 12 can take Gaviscon Advance Peppermint. Speak to your pharmacist or doctor before use if you are on a low-sodium diet or have kidney problems.

How to take Gaviscon Advance Peppermint

Take 5–10ml after meals and at bedtime, up to four times a day. Shake well before use. Do not exceed the recommended dose.
