All the products in the Gaviscon range are designed to combat heartburn and indigestion. We have been around for more than 45 years, providing treatment for heartburn and indigestion.

Gaviscon is made using all-natural seaweed. Side effects are very rarely reported. If you do experience any side effects they are highly likely to be mild and to go away when you stop taking Gaviscon.

Speak to your doctor if you experience:

  • Constipation
  • Diarrhoea
  • Nausea
  • Stomach Cramps
  • Taste Impairment
  • Vomiting

Always follow the instructions on the back of the product and patient information leaflet

If you ever forget to take a dose of Gaviscon, do not double the dose next time. Just carry on taking the medicine at the recommended dose. If symptoms persist after seven days, always consult your doctor. If you take too much Gaviscon it is unlikely to cause you much harm — although you may feel bloated. Consult your doctor or pharmacist if this feeling does not go away

How Gaviscon Original works

Why change what’s worked for over 45 years? You can enjoy relief from heartburn today with help from Gaviscon’s formulation.

It all starts with sodium alginate. Refined from brown seaweed which is sustainably harvested, this effective formulation acts as a protective barrier against discomfort and provides fast relief.

When the sodium alginate comes into contact with the irritating gastric acid, the alginate forms “raft”, which acts as a protective barrier over your stomach contents, stopping acid from rising and soothing the burning sensation in your chest in the process.

In short? You can get fast relief from those unpleasant sensations that both heartburn and indigestion sufferers know so well.
The Gaviscon formulation does not enter the bloodstream. It’s an effective product that’s free from gluten - with Gaviscon Original Liquid containing no sugar at all.

Sodium bicarbonate and calcium carbonate act as antacids, countering the problematic acid in the process. The protective barrier lasts for up to 4 hours.

For fast and effective aid, Gaviscon Original helps provide relief.

Sodium Alginate

Sodium alginate is extracted from the cell walls of seaweed. It helps the stomach block rising acid, the root cause of the discomfort heartburn and indigestion sufferers know so well.
