Antacid preparations such as rabeprazole by suppressing acid mediated break down of proteins, leads to an elevated risk of developing food or drug allergies. This happens due to undigested proteins then passing into the gastrointestinal tract where sensitisation occurs. It is unclear whether this risk occurs with only long-term use or with short-term use as well.
DRUG INTERACTION - Rabeprazole decreases the concentration of ketoconazole in the plasma (in 33%), increases the concentration of digoxin (in 22%), and does not interact with liquid antacids. Rabeprazole is compatible with any medicine metabolized by the CYP450 (theophylline, warfarin, diazepam, phenytoin).
OVER DOSAGE - Studies in mice and rats indicated the symptoms of acute toxicity due to overdose included: hypoactivity, labored respiration, convulsion, diarrhea, tremor, and coma. A study in dogs indicated that a dose of 2000mg/kg was not lethal.

Rabeprazole is in a group of drugs called proton pump inhibitors. Rabeprazole decreases the amount of acid produced in the stomach.
Rabeprazole is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome. Rabeprazole is also used to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid).
Rabeprazole may also be given with an antibiotic to prevent gastric 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.

Taking a proton pump inhibitor such as rabeprazole may increase your risk of bone fracture in the hip, wrist, or spine. This effect has occurred mostly in people who have taken the medication long term or at high doses, and in those who are age 50 and older. It is not clear whether rabeprazole is the actual cause of an increased risk of fracture. Before you take this medication, tell your doctor if you have osteoporosis or osteopenia (low bone mineral density).
