1. What Pantoprazole is and what it is used for

Pantoprazole contains the active substance pantoprazole (as sodium sesquihydrate). Pantoprazole is a selective “proton pump inhibitor”, a medicine which reduces the amount of acid produced in your stomach. It is used for treating acid-related diseases of the stomach and intestine.

This preparation is injected into a vein and will only be given to you if your doctor thinks pantoprazole injections are more suitable for you at the moment than pantoprazole tablets. Tablets will replace your injections as soon as your doctor sees fit.

Pantoprazole is used for treating:

  • Reflux oesophagitis. An inflammation of your oesophagus (the tube which connects your throat to your stomach) accompanied by the regurgitation of stomach acid.
  • Stomach and duodenal ulcers.
  • Zollinger-Ellison-Syndrome and other conditions producing too much acid in the stomach.

2. What you need to know before you are given Pantoprazole

Pantoprazole must not be given:

  • if you are allergic to pantoprazole or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to medicines containing other proton pump inhibitors.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before you are given Pantoprazole:

  • if you have severe liver problems. Tell your doctor if you ever had problems with your liver in the past. He will check your liver enzymes more frequently. In the case of a rise of liver enzymes the treatment should be stopped.
  • if you are taking a medicine containing atazanavir (for the treatment of HIV-infection) at the same time as pantoprazole, ask your doctor for specific advice.
  • if you have low magnesium levels in your body. This problem can be serious. Low magnesium can happen in some people who take a proton pump inhibitor medicine for at least 3 months. If low magnesium levels happen, it is usually after a year of treatment. You may or may not have symptoms of low magnesium.
  • if you are on pantoprazole for more than three months it is possible that the levels of magnesium in your blood may fall. Low levels of magnesium can be seen as fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness or increased heart rate. If you get any of these symptoms, please tell your doctor promptly. Low levels of magnesium can also lead to a reduction in potassium or calcium levels in the blood. Your doctor may decide to perform regular blood tests to monitor your levels of magnesium.
  • if you have ever had a skin reaction after treatment with a medicine similar to Pantoprazole that reduces stomach acid.

If you get a rash on your skin, especially in areas exposed to the sun tell your doctor as soon as you can, as you may need to stop your treatment with Pantoprazole. Remember to also mention any other ill-effects like pain in your joints.

People who take multiple daily doses of proton pump inhibitor medicines for a long period of time (a year or longer) may have an increased risk of fractures of the hip, wrist or spine. Talk to your doctor about your risk of bone fracture if you take Pantoprazole.

Tell your doctor immediately, before or after receiving this medicine, if you notice any of the following symptoms, which could be a sign of another, more serious, disease:

  • an unintentional loss of weight (not related to a diet or an exercise programme)
  • vomiting, particularly if repeated
  • vomiting blood; this may appear as dark coffee grounds in your vomit
  • you notice blood in your stools; which may be black or tarry in appearance
  • difficulty in swallowing or pain when swallowing
  • you look pale and feel weak (anaemia)
  • chest pain
  • stomach pain
  • severe and/or persistent diarrhoea, because this medicine has been associated with a small increase in infectious diarrhoea.

Your doctor may decide that you need some tests to rule out malignant disease because pantoprazole also alleviates the symptoms of cancer and could cause delay in diagnosing it. If your symptoms continue in spite of your treatment, further investigations will be considered.

Children and adolescents

Pantoprazole is not recommended for use in children and adolescents as it has not been proven to work in children and adolescents below 18 years of age.

Other medicines and Pantoprazole

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

In particular, tell your doctor if you are taking:

  • Medicines such as ketoconazole, itraconazole and posaconazole (used to treat fungal infections) or erlotinib (used for certain types of cancer) because Pantoprazole may stop these and other medicines from working properly.
  • Warfarin and phenprocoumon, which affect the thickening, or thinning of the blood. You may need further checks.
  • Atazanavir (used to treat HIV-infection) and other medicines used to treat HIV.
  • Methotrexate (used to treat rheumatoid arthritis, psoriasis, and cancer) – if you are taking methotrexate your doctor may temporarily stop your Pantoprazole treatment because pantoprazole can increase levels of methotrexate in the blood.

Pregnancy, breast-feeding and fertility

There are no adequate data from the use of pantoprazole in pregnant women. Excretion into human milk has been reported.

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby ask your doctor or pharmacist for advice before taking this medicine.

You should use this medicine, only if your doctor considers the benefit for you greater than the potential risk for your unborn child or baby.

Driving and using machines

If you experience side effects like dizziness or disturbed vision, you should not drive or operate machines.

Pantoprazole contains sodium

This medicine contains less than 1mmol sodium (23mg) per vial, that is to say is essentially ‘sodium- free’.

3. How Pantoprazole is given

Your doctor or nurse will administer the daily dose to you as an injection into a vein over a period of 2 - 15 minutes.

The recommended dose is:


  • For gastric ulcers, duodenal ulcers and reflux oesophagitis: One vial (40 mg pantoprazole) a day.
  • For the long-term treatment of Zollinger-Ellison syndrome and other conditions in which too much stomach acid is produced: Two vials (80 mg pantoprazole) a day.

Your doctor may later adjust the dose, depending on the amount of stomach acid you produce. If you are prescribed more than two vials (80 mg) a day, the injections will be given in two equal doses. Your doctor may prescribe a temporary dose of more than four vials (160 mg) a day. If your stomach acid level needs to be controlled rapidly, a starting dose of 160 mg (four vials) should be enough to lower the amount of stomach acid sufficiently.

Patients with liver problems

If you suffer from severe liver problems, the daily injection should be only 20 mg (half a vial).

Use in children and adolescents

This medicine is not recommended for use in children and adolescents under 18 years.

If you are given more Pantoprazole than you should

These doses are carefully checked by your nurse or your doctor so an overdose is extremely unlikely. There are no known symptoms of overdose.

If you have any further questions about the use of this medicine, ask your doctor or nurse.
