What Zantac oral liquid is used for
Zantac oral liquid belongs to a group of medicines called H2-antagonists.
It 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 oral liquid is also used to treat:
- Zollinger-Ellison disease,
- scleroderma oesophagitis.
These problems are improved by reducing the amount of acid in the stomach. Zantac oral liquid reduces stomach acid to decrease pain and allow the ulcer and reflux to heal.
Ask your doctor if you have any questions about why Zantac oral liquid has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
