What is AcipHex?
AcipHex (rabeprazole) is a proton pump inhibitor that decreases the amount of acid produced in the stomach.
AcipHex is used short-term to treat symptoms of gastroesophageal reflux disease (GERD) in adults and children who are at least 1 year old.
AcipHex 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).
AcipHex may also be given with an antibiotic to prevent duodenal ulcer caused by infection with Helicobacter pylori (H. pylori).
This medicine is not for immediate relief of heartburn symptoms.

You should not use AcipHex if you are allergic to rabeprazole or to similar medicines such as lansoprazole (Prevacid), esomeprazole (Nexium), omeprazole (Prilosec, Zegerid), or pantoprazole (Protonix). AcipHex is not for immediate relief of heartburn symptoms.
Some conditions are treated with a combination of AcipHex and antibiotics. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor’s advice.
Rabeprazole can cause kidney problems, an intestinal infection, or lupus (an autoimmune disorder).
Call your doctor right away if you have new or worsening joint pain, a skin rash that gets worse in sunlight, severe stomach pain, watery or bloody diarrhea, blood in your urine, or little or no urination.
Taking AcipHex may increase your risk of bone fracture in the hip, wrist, or spine, especially if you take the medicine long term or more than once per day.
Before taking this medicine
Heartburn is often confused with the first symptoms of a heart attack. Seek emergency medical attention if you have chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, and a general ill feeling.
You should not use AcipHex if you are allergic to rabeprazole or:
if you also take any medicine that contains rilpivirine, such as Edurant or Complera; or
if you also allergic to medicines like rabeprazole, such as esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec, Zegerid), or pantoprazole (Protonix).
To make sure AcipHex is safe for you, tell your doctor if you have ever had:
osteoporosis or low bone mineral density (osteopenia);
lupus (an autoimmune disorder); or
low levels of magnesium in your blood.
Taking a proton pump inhibitor such as AcipHex may increase your risk of bone fracture in the hip, wrist, or spine. This effect has occurred mostly in people who have taken the medicine long term or more than once per day, and in those who are age 50 and older. It is not clear whether AcipHex is the actual cause of an increased risk of fracture.
It is not known whether AcipHex will harm an unborn baby. Tell your doctor if you are pregnant.
It is not known whether rabeprazole passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
