What this medicine is used for

The name of your medicine is APO-Ranitidine tablets. It contains the active ingredient ranitidine (as hydrochloride).

It is used to treat:

  • Duodenal ulcer
  • Gastric ulcer
  • Reflux oesophagitis
  • Scleroderma oesophagitis
  • Zollinger-Ellison syndrome

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

This medicine is available only with a doctor's prescription.

How it works

Ranitidine belongs to a group of medicines called H2 antagonists or H2 blockers.

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

There is no evidence that this medicine is addictive.

Use in children

Experience with ranitidine preparations in children is limited and such use has not been fully evaluated in clinical studies. It has, however, been used successfully in children aged 8 to 18 years in doses up to 150 mg twice daily.
