Why it’s used
Pantoprazole oral tablet is used to reduce the amount of stomach acid your body makes. It helps treat painful symptoms caused by conditions such as gastroesophageal reflux disease (GERD). With GERD, gastric juices flow upward from your stomach and into the esophagus.
Pantoprazole oral tablet is also used to treat other conditions in which the stomach makes excess acid, such as Zollinger-Ellison syndrome.
How it works
Pantoprazole belongs to a class of drugs called proton pump inhibitors. It works to shut off the acid-pumping cells in your stomach. It reduces the amount of stomach acid and helps to reduce painful symptoms related to conditions such as GERD.
Pantoprazole oral tablet does not cause drowsiness. However, it can cause other side effects.
