Description

Gaviscon Advance is specially formulated to provide stronger and longer-lasting reflux protection compared to standard antacids. It creates a thick protective raft that sits on top of the stomach contents, helping to soothe irritation and reduce discomfort. Gaviscon Advance is suitable for adults and children over the recommended age who experience frequent heartburn or acid reflux.

  • Forms a protective barrier to prevent acid reflux
  • Provides long-lasting relief from heartburn
  • Suitable for use after meals and at bedtime
  • Available in liquid and sachet forms

Directions

Take Gaviscon Advance after meals and at bedtime, or as directed by your doctor or pharmacist. The usual dose for adults and children over twelve years is five to ten millilitres after meals and before going to bed. Shake the bottle well before use and measure the dose carefully using a spoon or dosing cup. Do not exceed the recommended dose, and consult a healthcare professional if symptoms persist after several days of use.

Ingredients

Gaviscon Advance contains sodium alginate and potassium bicarbonate as its active ingredients. Sodium alginate forms the protective raft barrier, while potassium bicarbonate helps neutralise excess stomach acid. Gaviscon Advance also contains flavourings and other excipients to stabilise the formulation.

Always check the packaging for the full ingredient list, especially if you are monitoring sodium intake or have allergies.

Warnings

Do not take Gaviscon Advance if you are allergic to any of its ingredients. Consult your doctor before using Gaviscon Advance if you have kidney problems, are on a low-sodium diet, or are taking other prescribed medications.

If symptoms worsen or do not improve after seven days, seek medical advice. Keep Gaviscon Advance out of sight and reach of children.

Frequently asked questions

  • What is Gaviscon Advance used for?

    Gaviscon Advance is used to relieve symptoms of acid reflux, heartburn, and indigestion. It works by forming a protective barrier that helps prevent stomach acid from rising into the oesophagus.

     

  • How does Gaviscon Advance work differently from standard antacids?

    Gaviscon Advance creates a thick raft-like layer that floats on top of stomach contents to reduce reflux. In addition, it helps neutralise excess acid to ease burning discomfort.

     

  • Can Gaviscon Advance be taken after meals?

    Yes, it is commonly taken after meals and at bedtime when reflux symptoms are more likely to occur. Taking it as directed helps maximise its protective effect.

     

  • Is Gaviscon Advance suitable during pregnancy?

    Gaviscon Advance is often recommended for heartburn during pregnancy due to its localised action in the stomach. However, pregnant individuals should consult a healthcare professional before use.

     

  • How quickly does Gaviscon Advance provide relief?

    Many people experience relief within minutes of taking Gaviscon Advance. The protective barrier forms rapidly to soothe irritation and reduce further acid exposure.
