Aciphex (rabeprazole) belongs to a group of drugs called proton pump inhibitors. Aciphex decreases the amount of acid produced in the stomach.
Aciphex is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome. It is also used to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid).
Aciphex may also be given with an antibiotic to prevent gastric ulcer caused by infection with helicobacter pylori (H. pylori).
Aciphex is not for immediate relief of heartburn symptoms.
Aciphex may also be used for other purposes not listed in this medication guide.
