What is Gaviscon Advance Liquid?

Gaviscon Advance Liquid is a remedy for indigestion, acid reflux and heartburn, helping to reduce excess stomach acid and the discomfort it causes. Gaviscon Advance Liquid is available in aniseed or peppermint flavours and is perfect for those who struggle with indigestion or heartburn after eating spicy or fatty foods, or after drinking coffee or alcohol. It can also help those who are suffering from acid reflux due to hiatus hernia.

NOW, what is indigestion?

Indigestion is a common problem affects a lot of people at some point. You’ll experience it after eating or drinking as excess stomach acid irritates your stomach lining. This causes uncomfortable symptoms including:


Burping or farting (wind)

Feeling full

Feeling sick


What about heartburn?

Heartburn is a symptom of acid reflux which occurs when excess stomach acid tries to move back up your food pipe, causing a burning sensation in the middle of your chest. Heartburn is a common problem and many people experience it once in a while, especially if they’ve eaten certain food or drink, are pregnant, or are overweight. Other symptoms you may experience when you have acid reflux include:

Sore throat



Bad breath

An unpleasant taste in the mouth

Bloating or feeling sick

How will Gaviscon Advance Liquid ease my heartburn?

Gaviscon Advance Liquid contains two active ingredients which work together to ease acid reflux and prevent heartburn. These ingredients are sodium alginate and potassium hydrogen carbonate, and they work as reflux suppressants. This means that they form a layer over the contents of your stomach, keeping excess stomach acid from moving up into your food pipe and causing irritation.
