What is rabeprazole?
Rabeprazole is a proton pump inhibitor that decreases the amount of acid produced in the stomach.
Rabeprazole is used only in adults to treat conditions involving excessive stomach acid, such as Zollinger-Ellison syndrome. Rabeprazole is also used in adults to promote healing of duodenal ulcers or erosive esophagitis (damage to your esophagus caused by stomach acid).
Rabeprazole is not for immediate relief of heartburn symptoms.
Rabeprazole may also be used for purposes not listed in this medication guide.
Rabeprazole can cause kidney problems. Tell your doctor if you are urinating less than usual, or if you have blood in your urine.
Diarrhea may be a sign of a new infection. Call your doctor if you have diarrhea that is watery or has blood in it.
You may be more likely to have a broken bone while taking rabeprazole long term or more than once per day.
