Heartburn & Indigestion Relief

Have questions about a Gaviscon product? We have answers!

How does Gaviscon work?

Gastro-oesophageal reflux (also known as heartburn or reflux) occurs when the contents of the stomach escape back up into the oesophagus (food pipe). The sodium alginate in Gaviscon acts as a ‘raft’ that forms over the contents of your stomach to help relieve reflux. Gaviscon Original soothes and cools the oesophagus, effectively relieving the classic – and often painful – symptoms of heartburn, so you can feel relief.

Gaviscon Original Liquid and Gaviscon Dual Action Liquid start to provide soothing relief from the symptoms of heartburn from as little as 4 minutes.*

Gaviscon Dual Action works in two different ways to effectively relieve the symptoms of heartburn and indigestion:

  1. The antacid – the antacid in Gaviscon Dual Action neutralises excess stomach acid to relieve the pain and discomfort of indigestion.
  2. The raft – the sodium alginate in Gaviscon Dual Action forms a thick layer (think of it like a soothing ‘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 oesophagus where they can cause discomfort and burning pain.
Our Extra Strength formula is designed to relieve the pain and discomfort of heartburn (gastric reflux) and indigestion. The sodium alginate in Gaviscon Extra Strength acts as a ‘raft’ that forms over the contents of your stomach to help relieve reflux.

Gaviscon Extra Strength contains double the concentration of sodium alginate compared with Gaviscon Original so you only need to take half as much.

Gaviscon Infant mixes with and stabilises stomach contents to prevent reflux and regurgitation.

Gaviscon during pregnancy

Heartburn is a common issue for pregnant women which involves acidic stomach contents being regurgitated back up the individual’s oesophagus, which can cause burning in the throat and chest. Symptoms are often worse immediately after eating or while lying down.

There are a number of everyday recommendations typically given to women who experience heartburn and wish to avoid or alleviate symptoms, including:

  • Eat smaller meals
  • Sleep in a more upright position
  • Avoid food 2-3 hours before bed, especially acidic and spicy food
  • Avoid smoking
  • Drink fluids mostly between meals instead of during the meal

The first line of treatment of heartburn in pregnancy is lifestyle changes. Eating smaller meals, not eating at night, raising your bedhead, and stopping smoking are all key steps to take.

In cases of more troublesome symptoms, or if symptoms persist despite lifestyle changes, you may wish to discuss medications with your doctor. There are a variety of such medications, but antacids are a fast and effective means to alleviate your heartburn and are commonly preferred due to their rapid symptom relief.

Gaviscon Double Strength Liquid has been shown to effectively relieve heartburn in pregnancy, with 90% of pregnant women rating it's efficacy as "good" or "very good".^

Speak to your doctor or healthcare professional if you are concerned about taking Gaviscon when pregnant or breastfeeding.
