Pantoprazole is a proton pump inhibitor that 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 is not for immediate relief of heartburn symptoms.
Important information
You should not use this medication if you are allergic to pantoprazole or to any other benzimidazole medication such as albendazole (Albenza), or mebendazole (Vermox).
Pantoprazole is not for immediate relief of heartburn symptoms.
Heartburn is often confused with the first symptoms of a heart attack. Seek emergency medical attention if you have chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, and a general ill feeling.
Take pantoprazole for the full prescribed length of time. Your symptoms may improve before the condition is fully treated.
Pantoprazole should not be taken together with atazanavir (Reyataz) or nelfinavir (Viracept). Tell your doctor if you are taking either of these medications to treat HIV or AIDS.
Some conditions must be treated long-term with pantoprazole. Chronic use 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. Talk with your doctor if you need long-term pantoprazole treatment and you have concerns about vitamin B-12 deficiency.

This effect has occurred mostly in people who have taken the medicine long term or at high doses, and in those who are age 50 and older. It is not clear whether pantoprazole is the actual cause of an increased risk of fracture.

-
Add 2 more teaspoons of apple juice to the syringe to rinse the granules through. Tap or shake the syringe as the juice empties into the tube.

Rinse with 2 teaspoons of apple juice at least twice more to make sure there are no granules remaining in the syringe or NG tube.
Take this medicine for the full prescribed length of time. Your symptoms may improve before the condition is fully treated.
