Generic name: pantoprazole (taken by mouth or injected) [pan-TOE-pra-zole]
Protonix is the brand name.
Proton pump inhibitors are a type of drug.
What is this drug called?
Pantoprazole is a proton pump inhibitor that lowers how much acid the stomach makes.
Pantoprazole is used to treat adults and children who are at least 5 years old who have erosive esophagitis. This is damage to the oesophagus from stomach acid caused by gastroesophageal reflux disease, or GERD. Most of the time, your doctor will give you pantoprazole for up to 8 weeks at a time while your oesophagus heals.
Pantoprazole is also used to treat Zollinger-Ellison syndrome and other stomach acid problems.
Pantoprazole is not used to get rid of heartburn symptoms right away.
People often think that the first signs of a heart attack are heartburn. Get emergency medical help if you have pain or a heavy feeling in your chest, pain that spreads to your arm or shoulder, nausea, sweating, or a general feeling of being sick.
If you take pantoprazole for a long time, it may also make it harder for your body to absorb vitamin B-12, which could lead to a lack of this vitamin. Talk to your doctor if you need to take pantoprazole for a long time and are worried about not getting enough vitamin B-12.
Pantoprazole can cause kidney problems. Tell your doctor if you’re not going to the toilet as much as usual or if there’s blood in your urine.
If you have diarrhoea, you might have a new infection. If you have diarrhoea that is watery or has blood in it, you should call your doctor.
Pantoprazole may cause or make lupus symptoms worse or bring on new ones. Tell your doctor if you have joint pain and a rash that gets worse in the sun on your cheeks or arms.
If you take this medicine for a long time or more than once a day, you may be more likely to break a bone.
