What is this medication for?
Rabeprazole belongs to the class of medications known as proton pump inhibitors (PPIs). Rabeprazole is used to treat and maintain healing of gastroesophageal reflux disease (GERD) in adults. It is also used for short-term treatment in the healing and relief of symptoms associated with duodenal ulcers. Rabeprazole works by reducing the production of acid in the stomach.
When used in combination with antibiotics, it is used to treat and eradicate H. pylori bacteria (the cause of most duodenal ulcers). Rabeprazole is also used for long-term treatment of conditions associated with constant production of excess acid in the stomach, including Zollinger-Ellison syndrome.
For children and adolescents 1 year of age and older, rabeprazole is used in the short-term treatment of GERD.
Most people will experience some improvements in symptoms 1 to 2 weeks after starting rabeprazole. It may take up to 4 weeks for people to experience maximum benefit from this medication.
