Generic Name: rabeprazole (ra-BEP-ra-zole)
Brand Name: Aciphex

Aciphex is used for:

Healing and maintaining healing of irritation of the esophagus. It is also used to treat symptoms of gastroesophageal reflux disease (GERD) (eg, heartburn). 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). It may also be used for other conditions as determined by your doctor.

Aciphex is a proton pump inhibitor. It works by decreasing the amount of acid produced in the stomach.

Do NOT use Aciphex if:

  • you are allergic to any ingredient in Aciphex or to similar medicines (eg, omeprazole)
  • you are taking atazanavir, dasatinib, erlotinib, or rilpivirine

Contact your doctor or health care provider right away if any of these apply to you.

How to use Aciphex:

Use Aciphex as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Aciphex comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Aciphex refilled.
  • Take Aciphex by mouth with or without food.
  • Swallow Aciphex whole. Do not break, crush, or chew before swallowing.
  • Tell your doctor if you cannot swallow tablets whole. You may need a different medicine.
  • You may take antacids while you are taking Aciphex if you are directed to do so by your doctor.
  • Continue to take Aciphex even if you feel well. Do not miss any doses.
  • If you miss a dose of Aciphex, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Aciphex.

Important safety information:

  • Contact your doctor if you have any symptoms of a bleeding ulcer, such as black, tarry stools or vomit that looks like coffee grounds, or if you experience throat pain, chest pain, severe stomach pain, or trouble swallowing.
  • Do NOT change your dose, stop taking Aciphex, or take Aciphex for longer than prescribed without checking with your doctor.
  • Aciphex may increase the risk of a serious form of diarrhea. Contact your doctor right away if stomach pain or cramps, severe or persistent diarrhea or fever, or bloody or watery stools occur. Discuss any questions or concerns with your doctor.
  • Aciphex may increase the risk of hip, wrist, and spine fractures in patients with weak bones (osteoporosis). The risk may be greater if you use Aciphex in high doses, for long periods of time, or if you are older than 50 years old. Contact your doctor if you have any questions about this information.
  • Low blood magnesium levels have been reported rarely in patients taking proton pump inhibitors for at least 3 months. In most cases, this effect was seen after a year of treatment. If you will be taking Aciphex for a long time, or if you take certain other medicines (eg, digoxin, diuretics), your doctor may perform lab tests to check for low blood magnesium levels. Seek medical attention right away if you experience symptoms of low blood magnesium levels (eg, dizziness; fast or irregular heartbeat; involuntary muscle movements; jitteriness or tremors; muscle aches, cramps, pain, spasms, or weakness; seizures).
  • Check with your doctor to see whether you should take a calcium and vitamin D supplement while you use Aciphex.
  • Tell your doctor or dentist that you take Aciphex before you receive any medical or dental care, emergency care, or surgery.
  • Use Aciphex with caution in the ELDERLY; they may be more sensitive to its effects, especially hip, wrist, and spine fractures.
  • Aciphex should be used with extreme caution in CHILDREN younger than 12 years old; safety and effectiveness in these children have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Aciphex while you are pregnant. It is not known if Aciphex is found in breast milk. If you are or will be breast-feeding while you use Aciphex, check with your doctor. Discuss any possible risks to your baby.
