What Zantac Syrup is used for

Zantac Syrup belongs to a group of medicines called H2-antagonists.

Zantac Syrup is mostly used to:

  • Treat stomach and duodenal ulcer disease (also known as peptic ulcer),
  • Stop these ulcers from coming back,
  • Treat reflux oesophagitis (also known as reflux or heartburn).

Zantac Syrup is also used to treat:

  • Zollinger-Ellison disease,
  • Scleroderma oesophagitis.

These problems are improved by reducing the amount of acid in the stomach. Zantac Syrup reduces stomach acid to decrease pain and allow the ulcer and reflux to heal.

Your doctor may have prescribed Zantac Syrup for another reason.

Ask your doctor if you have any questions about why Zantac Syrup has been prescribed for you.

Zantac Syrup is not addictive.
