It belongs to the group of medications known as other agents against peptic ulcers and gastroesophageal reflux.

It acts in two different ways:

1. Sodium alginate, along with sodium hydrogenocarbonate (bicarbonate) and calcium carbonate, form a protective barrier in the stomach to prevent gastric reflux and calm heartburn in the stomach.

2. Sodium hydrogenocarbonate (bicarbonate) and calcium carbonate additionally neutralize excess acid in the stomach.

Gaviscon is indicated for the symptomatic treatment of hyperacidity of the stomach and heartburn caused by acid reflux from the stomach in adults and adolescents over 12 years old.

You should consult a doctor if it worsens or does not improve after 7 days.
