Gaviscon Advance (liquid)

Gaviscon Advance Liquid

Gaviscon Advance is a reflux treatment for heartburn and indigestion, including acid reflux and the burning that comes with it. It carries double the sodium alginate of the original formula, is suitable for day or night use, and is free from sugar and gluten.

How it works

Alginate comes from seaweed, and on contact with stomach acid it sets into a raft that floats on top of the stomach contents. That raft is a physical barrier: it sits at the junction with the oesophagus and blocks acid from rising, which is why alginates suit reflux specifically rather than general stomach discomfort. The antacid component neutralises acid already present, which is what gives the fast soothing relief.

How to use it

Shake the bottle and take the dose stated on the pack after meals and at bedtime, since that is when reflux is most likely. Do not exceed the daily maximum. Alongside it, smaller evening meals, less alcohol and caffeine, not lying down soon after eating and raising the head of the bed all reduce night time reflux.

Who it is for

It is for adults and children as stated on the pack with heartburn, acid reflux or indigestion, including during pregnancy where alginates are commonly chosen. A pharmacist should be consulted if you are on a sodium restricted diet or have kidney problems.

Safety and when to get advice

See a doctor rather than self treating if you have difficulty or pain on swallowing, food sticking, unexplained weight loss, persistent vomiting, vomit that looks like coffee grounds, black tarry stools, or heartburn that is new over the age of 55 or needs treating most days for more than a couple of weeks. Seek emergency help for chest pain with breathlessness, sweating or pain spreading to the arm or jaw. Our UK pharmacy team can answer questions about this product before you buy.

Common questions

When should I take it?
After meals and at bedtime, since the raft works best sitting on top of a full stomach.

How is it different from an antacid?
An antacid neutralises acid. Gaviscon Advance also forms a raft that physically blocks acid from rising.

Can I use it in pregnancy?
Alginates are commonly used in pregnancy, but check with a pharmacist or midwife first.

Always read the patient information leaflet supplied with the pack before use.
