Pantoprazole is used to treat gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and injury of the food pipe (esophagus). It is also used to treat conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome. Pantoprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.

Pantoprazole comes as a delayed-release (long-acting) tablet to take by mouth. It is usually taken once or twice a day with or without food. To help you remember to take pantoprazole, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pantoprazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

SIDE EFFECTS, that may go away during treatment, include headache, dizziness, diarrhea, or nausea. If they continue or are bothersome, check with your doctor. CONTACT YOUR DOCTOR IMMEDIATELY if you experience swelling of hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; hoarseness; or rash. If you notice other effects not listed above, contact your doctor, nurse, or pharmacist.

If overdose is suspected, contact your local poison control center or emergency room immediately.
