Pantoprazole is used to treat certain stomach and esophagus problems (such as acid reflux). It works by decreasing the amount of acid your stomach makes. This medication relieves symptoms such as heartburn, difficulty swallowing, and cough. It helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Pantoprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).

To make sure you take the entire dose, rinse the cup once or twice with apple juice to mix any remaining granules, and swallow the juice. Do not prepare the mixture ahead of time for later use.

If you are giving the granules through a tube into the stomach (nasogastric or gastric tube), ask your health care professional for detailed instructions on how to properly mix and give it.

If you have these symptoms, do not use anti-diarrhea or opioid products because they may make symptoms worse.
