Uses for pantoprazole
Pantoprazole injection is used to treat certain conditions in which there is too much acid in the stomach. It is used for short-term treatment (7 to 10 days) of gastroesophageal reflux disease (GERD) with a history of erosive esophagitis. GERD is a condition in which the acid in the stomach washes back up into the esophagus. Pantoprazole may also be used to treat Zollinger-Ellison syndrome or other conditions (eg, cancer) in which the stomach produces too much acid.
Pantoprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach.
Pantoprazole is given only by or under the direct supervision of your doctor.
Before using pantoprazole
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For pantoprazole, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to pantoprazole or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of pantoprazole injection in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of pantoprazole injection in the elderly. However, elderly patients are more sensitive to the effects of pantoprazole than younger adults.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Interactions with medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.

Interactions with food/tobacco/alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur.

Proper use of pantoprazole
A nurse or other trained health professional will give you pantoprazole in a medical facility. It is given through a needle placed into one of your veins.
It may take several days before pantoprazole begins to relieve stomach pain. To help relieve this pain, antacids may be taken with pantoprazole, unless your doctor tells you otherwise.
Tell your doctor if you have had problems with your zinc levels in your body. Your doctor may want you to take zinc supplements.
Your doctor will give you a few doses of pantoprazole until your condition improves, and then switch you to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.
Precautions while using pantoprazole
It is important that your doctor check your progress at regular visits to make sure pantoprazole is working properly. Blood and urine tests may be needed to check for unwanted effects. If your condition does not improve, or if it becomes worse, check with your doctor.
You should not receive pantoprazole together with medicines containing rilpivirine (eg, Complera®, Edurant®, Odefsey®).
Pantoprazole may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing or swallowing, or any swelling of your hands, face, or mouth after you receive the medicine.
Serious skin reactions can occur with pantoprazole. Tell your doctor right away if you have blistering, peeling, or loosening of the skin, red skin lesions, severe acne or skin rash, sores or ulcers on the skin, or fever or chills while you are receiving pantoprazole.
Pantoprazole may cause an injection site reaction called thrombophlebitis. Check with your doctor right away if you notice any of these side effects at the injection site: changes in skin color, pain, tenderness, or swelling of the foot or leg.
Check with your doctor right away if you have a fever, joint pain, skin rash, swelling of the body, feet, or ankles, or unusual weight gain after receiving pantoprazole. These could be symptoms of a serious kidney problem called acute interstitial nephritis.
Pantoprazole may cause diarrhea, and in some cases it can be severe. Do not take any medicine to treat diarrhea without first checking with your doctor. Check with your doctor right away if you have watery diarrhea that does not go away, stomach pain, and fever while receiving pantoprazole.

Pantoprazole may cause hypomagnesemia (low magnesium in the blood). This is more likely to occur if you are using pantoprazole for more than 1 year, or if you are using pantoprazole together with digoxin (Lanoxin®) or certain diuretics (water pills). Check with your doctor right away if you have convulsions (seizures), fast, racing, or uneven heartbeat, muscle spasms (tetany), tremors, or unusual tiredness or weakness.
Cutaneous or systemic lupus erythematosus may occur or get worse in patients receiving a PPI. Call your doctor right away if you have joint pain or a skin rash on your cheeks or arms that gets worse when exposed to the sun.
Pantoprazole may increase your risk for fundic gland polyps (abnormal tissue growth in the upper part of your stomach). This is more likely if you are receiving pantoprazole for more than 1 year. Talk ti your doctor if you have concerns.
Make sure any doctor or dentist who treats you knows that you are using pantoprazole. Pantoprazole may affect the results of certain medical tests.
