Gaviscon Advance Liquid is a remedy for indigestion, acid reflux and heartburn, helping to keep excess stomach acid under control and keeping irritation at bay. Gaviscon Advance Liquid is available in delicious 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 because of a hiatus hernia or an inflamed food pipe.

What is indigestion?

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

  • Bloating
  • Burping or farting (wind)
  • Feeling full
  • Feeling sick
  • Heartburn

What is heartburn?

Heartburn is a symptom of a condition called acid reflux, and it happens 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
  • Coughs
  • Hiccoughs
  • 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.

Can I take this product if I’m taking other medication?
