Why is Aciphex prescribed?
Aciphex is used to treat conditions where the stomach produces too much acid, including ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. Aciphex is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.

How should Aciphex be used?
Aciphex comes as a delayed-release (long-acting) tablet to take by mouth. It is usually taken once a day for 4 to 8 weeks, but it is sometimes taken a for longer time. When taken for ulcers, Aciphex should be taken after the morning meal. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Aciphex exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
