Cancer: There is some evidence to suggest that people who take pantoprazole magnesium are at slightly increased risk of developing certain types of cancer, such as liver, thyroid, or stomach cancers. Talk to your doctor if you have concerns.
Infections: Pantoprazole magnesium changes the acidity of the digestive system, particularly the stomach. This increases the risk of certain types of infections in the digestive system. If you experience diarrhea with fever, chills, nausea or severe abdominal cramps, contact your doctor as soon as possible.
Kidney function: The kidneys are responsible for removing pantoprazole magnesium from the body. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: If you have severe liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Severe stomach problems: If you experience recurrent vomiting, difficulty swallowing, blood in the stool (dark stools), significant unintentional weight loss, fatigue, or are coughing up blood, contact your doctor right away. These may be symptoms of other medical problems that should be checked out by your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication may pass into breast milk. If you are a breast-feeding mother and are taking pantoprazole magnesium, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
