This leaflet does not have the complete information available about your medicine. If you have any questions about your medicine, you should ask your doctor or pharmacist (also known as chemist).

What is in my Zantac?

The medicine in your Zantac tablets is called ranitidine (as hydrochloride). This belongs to a group of medicines called H2-antagonists.

What does my Zantac do?

Zantac 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).

These problems are caused, in part, by too much acid in the stomach. This can lead to pain such as heartburn. Zantac works by reducing the amount of acid in the stomach. This reduces the pain and also allows the ulcer and reflux to heal.

Zantac is also used to treat:

  • Zollinger-Ellison disease,
  • scleroderma oesophagitis.
