What is pantoprazole?

Pantoprazole is in a group of drugs called proton pump inhibitors. It decreases the amount of acid produced in the stomach.

Pantoprazole is used to treat erosive esophagitis (damage to the esophagus from stomach acid), and other conditions involving excess stomach acid such as Zollinger-Ellison syndrome.

Pantoprazole may also be used for purposes other than those listed in this medication guide.

Precautions

Do not take this medication if you are allergic to pantoprazole. Before taking pantoprazole, tell your doctor if you are allergic to any drugs.

Some conditions must be treated long-term with pantoprazole. The chronic use of pantoprazole has caused stomach cancer in animal studies, but it is not known if this medication would have the same effects in humans. Talk with your doctor about your specific risk of developing stomach cancer.

Long-term treatment with pantoprazole may also make it harder for your body to absorb vitamin B-12, resulting in a deficiency of this vitamin. Symptoms of a vitamin B-12 deficiency may develop slowly and include pale skin, weakness, tired feeling, shortness of breath, and a fast heart rate. Talk with your doctor if you need long-term pantoprazole treatment and you have concerns about vitamin B-12 deficiency.
