Rabeprazole belongs to a class of anti-ulcer drugs known as proton pump inhibitors. Because the drug inhibits the secretion of gastric acid, it is used to treat gastro-oesophageal reflux disease (GORD), also called heartburn, and to help prevent it from recurring. It may also be used in the treatment of Zollinger-Ellison syndrome (a condition in which the stomach produces extremely large amounts of acid).
Rabeprazole may also be used to treat active duodenal and peptic ulcers by protecting them from the action of stomach acid, allowing them to heal. The drug is also used in combination with antibiotics to eradicate the Helicobacter pylori bacterium in patients with peptic ulcer disease. Rabeprazole is also occasionally prescribed to people who experience the gastrointestinal adverse effects associated with non-steroidal anti-inflammatory drugs (NSAIDs) but need to continue NSAID treatment.

POSSIBLE ADVERSE EFFECTS
Most common adverse effects of rabeprazole are mild and usually clear up without the need to discontinue treatment. They include headache, diarrhoea, abdominal pain, flatulence, and insomnia. Discuss with your doctor if they are severe or if you develop a cough, bronchitis, or sinusitis. Long-term use of rabeprazole increases the risk of intestinal infections and, in women, hip fractures (see Prolonged use).
Itraconazole and ketoconazole Rabeprazole reduces the effects of these drugs.
Digoxin Rabeprazole may increase the effects of digoxin.
Clopidogrel The antiplatelet effect of clopidogrel is reduced by rabeprazole.
Warfarin Rabeprazole increases the anticoagulant effect of warfarin.
Atazanavir Rabeprazole can reduce the blood levels of atazanavir, and the two drugs should not be used together.
Be sure to tell your doctor if:
· You are allergic to other proton pump inhibitors.
· You think you might be pregnant or are breast-feeding.
· You have a history of liver disease.
· You are taking other medicines.
Pregnancy Not prescribed. Safety not established.
Breast-feeding Not recommended. It is not known whether the drug passes into the breast milk. Discuss with your doctor.
Infants and children Not recommended.
Over 60 No special problems.
Driving and hazardous work Do not undertake such activities until you have learned how rabeprazole affects you because the drug can cause drowsiness.
Alcohol Avoid. Alcohol irritates the stomach, which can lead to ulceration and acid reflux.
Long-term use of rabeprazole may increase the risk of certain intestinal infections (such as Salmonella and Clostridium difficile infections) because of the loss of the natural protection against such infections provided by stomach acid. Prolonged use also increases the risk of hip fractures in women.
