Rabeprazole is used short-term to treat symptoms of gastroesophageal reflux disease (GERD) in adults and children who are at least 1 year old.

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 may also be given with an antibiotic to prevent duodenal ulcer caused by infection with Helicobacter pylori (H. pylori).

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.

Rabeprazole may cause new or worsening symptoms of lupus. Tell your doctor if you have joint pain and a skin rash on your cheeks or arms that worsens in sunlight.

You may be more likely to have a broken bone while taking rabeprazole long term or more than once per day.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.
