Read this Medication Guide before you start taking PROTONIX and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment.
What is the most important information I should know about PROTONIX?
PROTONIX may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.
PROTONIX can cause serious side effects, including:
- Diarrhea. PROTONIX may increase your risk
of getting severe diarrhea. This diarrhea may be caused by an infection (Clostridium
difficile) in your intestines.
Call your doctor right away if you have watery stool, stomach pain, and fever that does not go away.
- Bone fractures. People who take multiple daily doses of proton pump inhibitor medicines for a long period of time (a year or longer) may have an increased risk of fractures of the hip, wrist or spine. You should take PROTONIX exactly as prescribed, at the lowest dose possible for your treatment and for the shortest time needed. Talk to your doctor about your risk of bone fracture if you take PROTONIX.
PROTONIX can have other serious side effects. See “What are the possible side effects of PROTONIX?”
What is PROTONIX?
PROTONIX is a prescription medicine called a proton pump inhibitor (PPI). PROTONIX reduces the amount of acid in your stomach.
PROTONIX is used in adults:
- for up to 8 weeks to heal acid-related damage to the lining of the esophagus (erosive esophagitis or EE) and to relieve symptoms caused by gastroesophageal reflux disease (GERD). If needed, your doctor may decide to prescribe another 8 weeks of PROTONIX.
- to maintain the healing of acid-related damage to the lining of the esophagus and help prevent return of heartburn symptoms caused by GERD. It is not known if PROTONIX is safe and effective if used longer than 12 months (1 year). 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 the long-term treatment of conditions where your stomach makes too much acid. This includes a rare condition called Zollinger-Ellison syndrome.
PROTONIX is used in children 5 years of age and older for up to 8 weeks to heal acid-related damage to the lining of the esophagus (erosive esophagitis or EE) caused by GERD.
It is not known if PROTONIX is safe if used longer than 8 weeks in children. PROTONIX is not for use in children under 5 years of age.

Before taking PROTONIX, tell your doctor if you:

- Low magnesium levels in your body. This problem can be serious. Low magnesium can happen in some people who take a proton pump inhibitor medicine for at least 3 months. If low magnesium levels happen, it is usually after a year of treatment. You may or may not have symptoms of low magnesium.
