About rabeprazole

Rabeprazole reduces the amount of acid your stomach makes. It's widely used to treat heartburn, acid reflux and gastro-oesophageal reflux disease (GORD). GORD is when you keep getting acid reflux.

Rabeprazole is also taken to prevent and treat stomach ulcers.

Sometimes, it is also prescribed for a rare condition caused by a tumour in the pancreas or gut, called Zollinger-Ellison syndrome.

Rabeprazole is only available on prescription. It comes as tablets.
