What is ACIPHEX?

ACIPHEX is a prescription medicine called a proton pump inhibitor (PPI). ACIPHEX reduces the amount of acid in your stomach.

ACIPHEX is used in adults:

  • for up to 8 weeks to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE) and to relieve symptoms, such as heartburn pain. If needed, your doctor may decide prescribe another 8 weeks of ACIPHEX.
  • to maintain the healing of the esophagus and relief of symptoms related to EE. It is not known if ACIPHEX is safe and effective if used longer than 12 months (1 year).
  • for 4 weeks to treat daytime and nighttime heartburn and other symptoms that happen with Gastroesophageal Reflux Disease (GERD).
    GERD happens when acid in your stomach backs up into the tube (esophagus) that connects your mouth to your stomach. This may cause a burning feeling in your chest or throat, sour taste, or burping.
  • for up to 4 weeks for the healing and relief of duodenal ulcers. The duodenal area is the area where food passes when it leaves the stomach.
  • for 7 days with certain antibiotic medicines to treat an infection caused by bacteria called H. pylori. Sometimes H. pylori bacteria can cause duodenal ulcers. The infection needs to be treated to prevent the ulcers from coming back.
  • for the long-term treatment of conditions where your stomach makes too much acid. This includes a rare condition called Zollinger-Ellison syndrome.

ACIPHEX is used in adolescents 12 years of age and older:

  • for up to 8 weeks to treat daytime and nighttime heartburn and other symptoms that happen with Gastroesophageal Reflux Disease (GERD).
