What Ranitidine Sandoz Injection is used for

The name of your medicine is Ranitidine Sandoz Injection. It contains the active ingredient ranitidine (as hydrochloride).

Ranitidine Sandoz Injection is used to treat a variety of conditions. If you are unsure why you have been prescribed Ranitidine Sandoz Injection, talk to your doctor.

Ranitidine Sandoz Injection is used to treat 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 made in the stomach.

Ranitidine Sandoz Injection is also used to help stop ulcers from coming back.

Ranitidine Sandoz Injection is used to 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.

Ranitidine Sandoz Injection is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces very large amounts of acid, much more than in ulcers and reflux disease.

Ranitidine Sandoz Injection may be used to treat scleroderma oesophagitis. Scleroderma is a rare condition, and in scleroderma oesophagitis the food pipe is abnormal and there is reflux.

Ask your doctor if you have any questions about why Ranitidine Sandoz Injection was prescribed for you. Your doctor may have prescribed it for another reason.

How Ranitidine Sandoz Injection works

Ranitidine Sandoz Injection 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 reduce the pain and also allows the ulcer to heal in most people.

There is no evidence that Ranitidine Sandoz Injection is addictive.
