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.11
  • 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 belong11
    in your stomach – and not in your food pipe where they can cause discomfort
    and burning pain4.


Whilst indigestion alone may not lead to serious complications, it can impact your day-to-day life. People suffering from indigestion long term may experience disturbed sleep, which can in turn affect how productive you are at work or school. Lack of sleep can also affect your mental health and wellbeing.12,13

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

Always read the label and follow the directions for use.


Indigestion, or dyspepsia, is discomfort or pain in the middle to upper part of your stomach area (abdomen) that can occur during or after eating or drinking. It is often associated with feeling too full after eating a meal or too full to even finish eating a meal.

Medications that reduce the amount of acid in your stomach can help relieve the pain and discomfort of indigestion. Gaviscon Dual Action contains an antacid that neutralises excess stomach acid and sodium alginate to form a protective layer over the acidic stomach contents – helping to relieve the pain and discomfort of indigestion.

You can help avoid indigestion by watching what you eat and drink – limiting those things that you know can trigger your symptoms. Foods that commonly cause indigestion include fatty, spicy, or acidic foods, alcohol, caffeine, and soft drinks. Eating smaller meals more slowly and waiting a few hours after eating before exercising or lying down can also help reduce indigestion. Other lifestyle changes to help prevent indigestion include maintaining a healthy weight, not smoking, reducing stress, and talking to your doctor about medications that may cause indigestion.

Indigestion may occur once in a while or happen more regularly for weeks or even months. You should speak with your doctor if your indigestion lasts longer than 2 weeks or you have any concerns about your symptoms at any time.

For some people, drinking too much coffee or other drinks that contain caffeine can cause indigestion. In fact, coffee has been shown to stimulate the production of stomach acid regardless of how much caffeine it contains. Everyone is different though – so it’s important to figure out whether that latte is one of your indigestion triggers or not!

The common symptoms of indigestion generally don’t include diarrhoea and indigestion is not typically associated with changes in bowel habits. However, each person’s experience of indigestion is different, so it’s a good idea to discuss your symptoms with your doctor if you are unsure.

People of all ages can get indigestion. So, if your child complains of an upset stomach, it could be indigestion – but if you have any concerns or questions about their symptoms, consult your doctor.
