Aciphex is used for treating heartburn or irritation of the esophagus caused by gastroesophageal reflux disease (GERD). It may be used for short-term treatment of ulcers of the small intestine. It may be used with certain antibiotics to treat ulcers of the small intestine and to help prevent them from coming back. It may be used to treat conditions that cause your body to make too much stomach acid (eg, Zollinger-Ellison syndrome). Aciphex is a proton pump inhibitor. It works by decreasing the amount of acid produced in the stomach.
