Overview of the medicine
Naviscon 250 mg Chewable Tablet is an antacid and reflux suppressant used for the relief of heartburn, indigestion, and acid reflux symptoms. It forms a protective barrier over the stomach contents.

How to Take
The tablet should be chewed thoroughly before swallowing. Do not swallow whole. Take after meals and at bedtime.
Mechanism of Action
Sodium alginate reacts with gastric acid to form a viscous gel (raft) which floats on top of the stomach contents, preventing reflux. Calcium carbonate and sodium bicarbonate provide immediate antacid action by neutralizing stomach acid.
