What is the most important information I should know about Pantoprazole?

You should take Pantoprazole exactly as prescribed, at the lowest dose possible and for the shortest time needed.

Pantoprazole may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.

Pantoprazole can cause serious side effects, including:

  • A type of kidney problem (acute tubulointerstitial nephritis). Some people who take proton pump inhibitor (PPI) medicines, including Pantoprazole, may develop a kidney problem called acute tubulointerstitial nephritis that can happen at any time during treatment with Pantoprazole. Call your doctor right away if you have a decrease in the amount that you urinate or if you have blood in your urine.

  • Diarrhea caused by an infection (Clostridium difficile) in your intestines. Call your doctor right away if you have watery stools or stomach pain that does not go away. You may or may not have a fever.

  • Bone fractures (hip, wrist, or spine). Bone fractures in the hip, wrist, or spine may happen in people who take multiple daily doses of PPI medicines and for a long period of time (a year or longer). Tell your doctor if you have a bone fracture, especially in the hip, wrist, or spine.

  • 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, 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.

  • Low magnesium and other mineral levels in your body can happen in people who have taken Pantoprazole for at least 3 months. Tell your doctor if you have symptoms of low magnesium levels, including seizures, dizziness, irregular heartbeat, jitteriness, muscle aches or weakness, and spasms of hands, feet or voice.

Talk to your doctor about your risk of these serious side effects.

Pantoprazole can have other serious side effects. See What are the possible side effects of Pantoprazole?”

What is Pantoprazole?

A prescription medicine called a proton pump inhibitor (PPI) used to reduce the amount of acid in your stomach.

In adults, Pantoprazole is used for:

  • up to 8 weeks for the healing and symptom relief of acid-related damage to the lining of the esophagus (called erosive esophagitis or EE). Your doctor may prescribe another 8 weeks of Pantoprazole in patients whose EE does not heal.

  • maintaining healing of EE and to help prevent the return of heartburn symptoms caused by GERD. It is not known if Pantoprazole is safe and effective when used for longer than 12 months for this purpose.

  • the long-term treatment of conditions where your stomach makes too much acid.  This includes a rare condition called Zollinger-Ellison Syndrome.

In children 5 years of age and older, Pantoprazole is used for:

  • up to 8 weeks for the  healing and symptom relief of EE.

    It is not known if Pantoprazole is safe if used longer than 8 weeks in children.
