Pantoprazol Alter is a selective proton pump inhibitor, a medication that reduces the amount of acid produced in your stomach. It is used for the treatment of diseases related to stomach acid and intestine.

Pantoprazol Alter is used for:

Adults and adolescents 12 years of age and older:

• Esophagitis caused by reflux. It is an inflammation of your esophagus (the tube that connects your throat to your stomach) accompanied by regurgitation of acid from your stomach.

Adults:

• Infection caused by a bacteria called Helicobacter pylori in patients with stomach and/or duodenal ulcers in combination with two antibiotics (eradication treatment). The goal is to get rid of the bacteria and thus reduce the likelihood of ulcers reappearing.
• Stomach and duodenal ulcers, and
• Zollinger-Ellison syndrome and other conditions in which too much acid is produced in the stomach.

Do not take Pantoprazol Alter

• If you are allergic (hypersensitive) to pantoprazole or to any of the other components of Pantoprazol Alter (see section 6)
• If you are allergic to medications that contain other proton pump inhibitors (e.g., omeprazole, lansoprazole, rabeprazole, esomeprazole)

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Pantoprazol Alter:

• If you have severe liver problems. Inform your doctor if you have ever had liver problems. Your doctor will monitor your liver enzymes more frequently, especially when you are on long-term treatment with pantoprazole. If liver enzyme levels increase, treatment should be interrupted.
• If you have reduced vitamin B12 reserves or risk factors for it and receive pantoprazole treatment for a long period. Like all medications that reduce acid production, pantoprazole may reduce vitamin B12 absorption.
• Consult your doctor if you are taking any medication that contains atazanavir (for HIV treatment) at the same time as pantoprazole.
• Taking a proton pump inhibitor like pantoprazole, especially for more than a year, may increase the risk of fractures of the hip, wrist, or spine.

Inform your doctor if you have osteoporosis (reduced bone density) or if you have been told you are at risk of developing osteoporosis (for example, if you are taking corticosteroids).

• If you take pantoprazole for more than three months, you may experience a decrease in magnesium levels in your blood. Symptoms of low magnesium levels may include fatigue, involuntary muscle contractions, disorientation, dizziness, or increased heart rate. If you experience any of these symptoms, inform your doctor immediately. Low magnesium levels can cause a decrease in potassium and calcium levels in your blood. Your doctor will decide to perform periodic blood tests to monitor magnesium levels.
• If you have ever had a skin reaction after treatment with a similar medication to Pantoprazol Alter for reducing stomach acid.

If you experience a skin rash, especially in sun-exposed areas, consult your doctor as soon as possible, as it may be necessary to interrupt treatment with Pantoprazol Alter. Remember to mention any other symptoms you may notice, such as joint pain.

• If you are scheduled to have a specific blood test (Cromogranin A)

Inform your doctor immediatelyif you notice any of the following symptoms:

-unintentional weight loss

-repeated vomiting

-difficulty swallowing

-blood in your vomit; it mayappear as a dark brown powder in your vomit

-blood in your stools, which may appear black or melena

-difficulty swallowing, or pain when swallowing

-pale appearance and feeling weak (anemia)blood in your stools

• chest pain

• stomach painsevere or persistent diarrhea, as pantoprazole has been associated with a small increase in infectious diarrhea.

Your doctor will decide if you need additional testing to rule out a malignant disease, as pantoprazole may alleviate cancer symptoms and potentially delay diagnosis. If your symptoms persist despite treatment, further investigations will be performed.

If you take pantoprazole for a prolonged period (more than a year), your doctor may regularly monitor you. You should inform your doctor of any new or unexpected symptoms and/or events each time you attend your consultation.
