What is pantoprazole?
Pantoprazole is a proton pump inhibitor that decreases the amount of acid produced in the stomach.
Pantoprazole is used to treat erosive esophagitis (damage to the esophagus from stomach acid caused by gastroesophageal reflux disease, or GERD) in adults and children who are at least 5 years old. Pantoprazole is usually given for up to 8 weeks at a time while your esophagus heals.
Pantoprazole is also used to treat Zollinger-Ellison syndrome and other conditions involving excess stomach acid.
Pantoprazole is not for immediate relief of heartburn.
Pantoprazole may also be used for purposes not listed in this medication guide.
Pantoprazole can cause kidney problems. Tell your doctor if you are urinating less than usual, or if you have blood in your urine.
Diarrhea may be a sign of a new infection. Call your doctor if you have diarrhea that is watery or has blood in it.
You may be more likely to have a broken bone while taking this medicine long term or more than once per day.
