Gaviscon is designed to treat heartburn and indigestion. It works by forming a protective layer of gel that floats like a raft on the top of your stomach content. This prevents acid from returning back into your throat. It also contains an antacid which helps neutralise the stomach acids. Gaviscon is the market leader in heartburn and acid reflux medication.

How Effective Is Gaviscon?

Gaviscon is an effective treatment for indigestion and heartburn. In addition to its fast-acting, acid-neutralising properties, Gaviscon is the only antacid product that provides long-lasting relief. The “floating raft” created on the surface of the stomach acid is very effective at preventing acid from going back up the throat.

Adults should take 10-20ml after meals and at bedtime, up to four times a day.

  2. Shake well before use.

  3. Adults take 10-20ml (two to four 5ml spoonfuls) after meals and at bedtime, up to four times a day.

If symptoms persist after 7 days, consult your doctor.

How does Gaviscon work? 

Heartburn and acid reflux are painful conditions that affect the stomach and food pipe. They occur when stomach acid flows back up up the food pipe, causing pain and a burning sensation.

Gaviscon is classified as a reflux suppressant. It works by forming a protective gel layer that floats on top of the stomach contents to prevent acid from returning from the stomach back  into the food pipe. The fluid also helps to neutralise stomach acid.

How long do I need to take Gaviscon before I notice a difference? 

Gaviscon should take effect immediately after consumption. The floating gel “raft” will last around 4 hours before needing replacement. If symptoms continue after 7 days of use then consult your doctor.

What are the side effects of Gaviscon?

Very rarely (less than 1 in 10,000 patients treated) an allergic reaction to the ingredients may occur. Symptoms of this may include skin rash, difficulty in breathing, dizziness, or swelling of the face, lips, tongue or throat. If you experience these or any other side-effects, stop taking the product and consult your doctor or pharmacist.

What is the difference between Gaviscon and Setlers antacid/Maalox?

Gaviscon is a liquid that forms a protective layer over the contents of your stomach and prevents stomach acid from entering the food tube. It also helps to neutralise stomach acid.

Setlers antacid tablets are designed to neutralise the acid in your stomach. They do not provide a protective layer in the way Gaviscon does.
Maalox works similarly to Gaviscon and produces a protective layer over the stomach acids. It also helps to neutralise stomach acid.
