About Ranitidine

Ranitidine is a rapidly-acting histamine H2-antagonist which is used in the treatment of acid reflux/heartburn (gastroesophageal reflux disease). Ranitidine works to reduce the amount of stomach acid released by acting on cells in the stomach. By doing this, symptoms of heartburn are reduced.

NOTE: This medication should be taken for a maximum of 4-5 days. If symptoms persist after this time, please see your GP, as the symptoms require investigation. Acid reflux medications can mask the symptoms of more serious conditions, such as oesophagal cancer.
