Gaviscon Double Strength

Print Friendly, PDF & Email

Generic Name: Calcium carbonate; Potassium bicarbonate; Sodium alginate
Product Name: Gaviscon Double Strength


Gaviscon Double Strength can be used for symptomatic relief of problems caused by reflux of gastric contents:

  • Heartburn (including heartburn of pregnancy)
  • Dyspepsia
  • Reflux oesophagitis
  • Hiatus hernia especially in cases where Gaviscon (normal strength) has been unsuccessful.


The main ingredient in Gaviscon Double Strength, sodium alginate, works as an anti-reflux agent. It reacts with the acid found in the stomach to produce a frothy layer over the stomach contents, which then prevents reflux. The sensitive mucosa of the oesophagus is no longer exposed to gastric acid and the pain associated with these conditions is relieved. Continued use of Gaviscon Double Strength and ongoing prevention of reflux allows the damaged tissues to be repaired.

  • 5-10ml after meals and 30 minutes before bedtime.
  • Dose may be repeated at other times if necessary.

There have been minimal side effects associated with use of Gaviscon Double Strength.
