What Are the Side Effects of Aciphex?

Achiphex, or rabeprazole, is a drug that helps to decrease gastric secretions by inhibiting the production of hydrogen ions in the stomach. It is classified as a proton pump inhibitor, or PPI.
Achipex is used to treat both moderate and severe gastroesophageal reflux (GERD), duodenal ulcers and other conditions resulting from hypersecretion of stomach acid. It may also be used as part of a combination regimen to treat the Helicobacter pylori bacterium responsible for certain types of ulcers.
