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.
