Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Ranitidine Sandoz.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risk of you taking this medicine against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist. Keep this leaflet with the medicine. You may need to read it again.

What Ranitidine Sandoz is used for

This medicine is used to treat:

  • Treat stomach and duodenal ulcer disease (also known as peptic ulcers). Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out of the stomach. These can be caused in part by too much acid being produced in the stomach. Ranitidine Sandoz is also used to help stop these ulcers from coming back.
  • Stop these ulcers from coming back
  • Treat reflux oesophagitis or reflux disease. This can be caused by “washing back” (reflux) of food and acid from the stomach into the food pipe, also known as the oesophagus. Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn
  • Treat Zollinger-Ellison syndrome, a rare condition where the stomach produces very large amounts of acid, much more than in ulcers and reflux disease.
  • Treat Scleroderma oesophagitis. Scleroderma is a rare condition, and in scleroderma oesophagitis the food pipe is abnormal and reflux occurs.

It contains the active ingredient ranitidine hydrochloride. Ranitidine hydrochloride belongs to a group of medicines called H2 antagonists or H2 blockers.

It works by decreasing the amount of acid made by the stomach. This helps to reduce the pain and also allows the ulcer and/or reflux disease to heal in most people.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

There is no evidence that Ranitidine Sandoz is addictive.
