Uses For Protonix

Pantoprazole injection is used to treat certain conditions in which there is too much acid in the stomach. It is used for short-term treatment (7 to 10 days) of gastroesophageal reflux disease (GERD) with a history of erosive esophagitis. GERD is a condition in which the acid in the stomach washes back up into the esophagus. This medicine may also be used to treat Zollinger-Ellison syndrome or other conditions (e.g., cancer) in which the stomach produces too much acid.

Pantoprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach.

This medicine is available only with your doctor's prescription.
