Read this Medication Guide before you start taking pantoprazole sodium 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 pantoprazole sodium?
Pantoprazole sodium may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.
Pantoprazole sodium can cause serious side effects, including:
- A type of kidney problem (acute interstitial nephritis). Some people who take proton pump inhibitor (PPI) medicines, including pantoprazole sodium, may develop a kidney problem called acute interstitial nephritis that can happen at any time during treatment with pantoprazole sodium. Call your doctor if you have a decrease in the amount that you urinate or if you have blood in your urine.
- Diarrhea. Pantoprazole sodium 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 PPI 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 pantoprazole sodium 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 pantoprazole sodium.
- Certain types of lupus erythematosus. Lupus erythematosus is an autoimmune disorder (the body's immune cells attack other cells or organs in the body). Some people who take PPI medicines, including pantoprazole sodium, may develop certain types of lupus erythematosus or have worsening of the lupus they already have. Call your doctor right away if you have new or worsening joint pain or a rash on your cheeks or arms that gets worse in the sun.
Pantoprazole sodium can have other serious side effects. See "What are the possible side effects of pantoprazole sodium?"
What is pantoprazole sodium?
Pantoprazole sodium is a prescription medicine called a proton pump inhibitor (PPI).
Pantoprazole sodium reduces the amount of acid in your stomach.
Pantoprazole sodium 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 pantoprazole sodium.
- 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 pantoprazole sodium 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.
Pantoprazole sodium 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 pantoprazole sodium is safe if used longer than 8 weeks in children. Pantoprazole sodium is not for use in children under 5 years of age.
