Medication like Gaviscon Dual Action contains both an antacid and alginate to help relieve
indigestion in two ways.

  • The antacid – the antacid in Gaviscon Dual Action neutralises excess
    stomach acid to relieve the pain and discomfort of indigestion.
  • The raft – the sodium alginate in Gaviscon Dual Action forms a thick layer
    (think of it like a ‘raft’) on top of your stomach contents. The ‘raft’ then acts as
    a physical barrier that helps keep your stomach contents where they belong–
    in your stomach – and not in your food pipe where they can cause discomfort
    and burning pain.

If your symptoms do not resolve or if your symptoms are troubling or concern you, speak to
your doctor.
