Why is this medication prescribed?
Rabeprazole is used to treat gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and possible injury of the esophagus (the tube that connects the throat and stomach). Rabeprazole is used to treat the symptoms of GERD, allow the esophagus to heal, and prevent further damage to the esophagus. Rabeprazole is also used to treat conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome. Rabeprazole is used to treat ulcers (sores in the lining of the stomach or intestine) and is used in combination with other medications to eliminate H. pylori, a bacteria that causes ulcers. Rabeprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.
How should this medicine be used?
Rabeprazole comes as a delayed-release (releases the medication in the intestine to prevent break-down of the medication by stomach acids) tablet to take by mouth. When rabeprazole is used to treat most conditions, it is usually taken once a day. When used to treat ulcers, rabeprazole is taken after the morning meal. When used in combination with other medications to eliminate H. pylori, rabeprazole is taken twice a day, with the morning and evening meals, for 7 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take rabeprazole exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.
Swallow the tablets whole with water; do not split, chew, or crush them.
Continue to take rabeprazole even if you feel well. Do not stop taking rabeprazole without talking to your doctor. If your condition does not improve or gets worse, call your doctor.
