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 caused by gastroesophageal reflux disease, or GERD) in adults and children who are at least 5 years old. Pantoprazole is usually given for up to 8 weeks at a time while your esophagus heals.

Pantoprazole is also used to treat Zollinger-Ellison syndrome and other conditions involving excess stomach acid.

Pantoprazole is not for the 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.

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.

Pantoprazole can cause kidney problems. Tell your doctor if you are urinating less than usual, or if you have blood in your urine.

Diarrhea may be a sign of a new infection. Call your doctor if you have diarrhea that is watery or has blood in it.

Pantoprazole may cause new or worsening symptoms of lupus. Tell your doctor if you have joint pain and a skin rash on your cheeks or arms that worsens in sunlight.

You may be more likely to have a broken bone while taking this medicine long term or more than once per day.

Take pantoprazole exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Use the lowest dose for the shortest amount of time needed to treat your condition.

Pantoprazole is taken by mouth (oral) or given as an infusion into a vein (injection). A healthcare provider may teach you how to properly use the injection by yourself.

Pantoprazole tablets are taken by mouth, with or without food. The oral granules should be taken 30 minutes before a meal.

Do not crush, chew, or break the tablet. Swallow it whole.

The oral granules should be mixed with applesauce or apple juice and given either by mouth or through a nasogastric (NG) tube.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you have any questions.

Use this medicine for the full prescribed length of time, even if your symptoms quickly improve.

Call your doctor if your symptoms do not improve or if they get worse while you are using this medicine.

Pantoprazole can cause false results with certain medical tests. Tell the doctor or laboratory staff that you are using this medicine.

Pantoprazole may also affect a drug-screening urine test and you may have false results. Tell the laboratory staff that you use this medicine.

Store this medicine at room temperature away from moisture, heat, and light.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
