1. What is Omeprazol Medreg and what is it used for

Omeprazol Medreg contains the active substance omeprazole. It belongs to a group of medicines called "proton pump inhibitors". Their action is to reduce the amount of acid produced in the stomach.

Omeprazol Medreg is used to treat the following diseases:

In adults:

• Gastroesophageal reflux disease. This is when stomach acid flows back into the esophagus (the tube connecting the throat to the stomach), causing pain, inflammation, and heartburn.
• Ulcers in the upper part of the small intestine (duodenal ulcers) or stomach (gastric ulcers).
• Ulcers infected with bacteria called "Helicobacter pylori". In such cases, the doctor may also prescribe antibiotics to cure the infection and allow the ulcers to heal.
• Ulcers caused by medications known as non-steroidal anti-inflammatory drugs (NSAIDs). Omeprazol Medreg can also be used to prevent the development of ulcers when taking NSAIDs.
• Excessive stomach acid due to the presence of a tumor in the pancreas (Zollinger-Ellison syndrome).

In children

Children over 1 year of age and with a body weight of ≥ 10 kg:

• Gastroesophageal reflux disease. This is when stomach acid flows back into the esophagus (the tube connecting the throat to the stomach), causing pain, inflammation, and heartburn.

In children, symptoms of this disorder may include: regurgitation of stomach contents into the mouth (regurgitation, vomiting), vomiting, and insufficient weight gain.

Children and adolescents over 4 years of age:

• Ulcers infected with bacteria called "Helicobacter pylori". If the child has this disease, the doctor may also prescribe antibiotics to cure the infection and allow the ulcers to heal.

2. Important information before taking Omeprazol Medreg

When not to take Omeprazol Medreg:

• If the patient has been diagnosed with an allergy (hypersensitivity) to omeprazole or any of the other ingredients of Omeprazol Medreg (listed in section 6).
• If the patient has been diagnosed with an allergy to medicines containing other proton pump inhibitors (e.g., pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• If the patient is taking a medicine containing nelfinavir (used to treat HIV infection).

Do not take Omeprazol Medreg if any of the above situations apply to the patient. Before starting to take Omeprazol Medreg, discuss this with a doctor or pharmacist.

Warnings and precautions

Before starting to take Omeprazol Medreg, discuss this with a doctor or pharmacist.

In connection with the treatment with Omeprazol Medreg, severe skin reactions have been reported, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash with eosinophilia and systemic symptoms (DRESS syndrome), and acute generalized exanthematous pustulosis (AGEP). In case of noticing any symptoms related to these severe skin reactions described in section 4, stop taking Omeprazol Medreg and seek medical help immediately.

Omeprazol Medreg may mask the symptoms of other diseases. For this reason, if any of the following conditions occur before starting or during treatment with Omeprazol Medreg, contact a doctor immediately:

• Unexplained weight loss and difficulty swallowing.
• Stomach pain or indigestion.
• Vomiting blood or food.
• Passing black stools (stool discolored with blood).
• Severe or persistent diarrhea, as the use of omeprazole is associated with a slight increase in the frequency of infectious diarrhea.
• Severe liver disease.
• If the patient has ever had a skin reaction after taking a medicine similar to Omeprazol Medreg, which reduces stomach acid production.
• Planned specific blood test (chromogranin A levels).

In the case of long-term use of Omeprazol Medreg (longer than 1 year), the patient will most likely remain under close and regular medical supervision. During the visit to the doctor, all new and unusual symptoms and circumstances should be reported.

Taking a proton pump inhibitor, such as Omeprazol Medreg, especially for a period longer than a year, may slightly increase the risk of hip, wrist, or spine fractures. Inform the doctor if there is osteoporosis or if corticosteroids are being taken (which may increase the risk of osteoporosis).

If the patient experiences a skin rash, especially in areas exposed to sunlight, they should inform their doctor as soon as possible, as it may be necessary to stop taking Omeprazol Medreg. They should also report any other side effects, such as joint pain.

During the treatment with omeprazole, kidney inflammation may occur. Symptoms may include decreased urine output or blood in the urine and (or) hypersensitivity reactions, such as fever, rash, and joint stiffness. The patient should report such symptoms to their doctor.

This medicine may affect the way the body absorbs vitamin B12, especially if it needs to be taken for a long time. Inform the doctor if any of the following symptoms are noticed, which may indicate a low level of vitamin B12:

• Extreme fatigue or lack of energy
• Numbness and tingling
• Painful or red tongue, mouth ulcers
• Muscle weakness
• Vision disturbances

Do not take Omeprazol Medreg if you are taking a medicine containing nelfinavir (used to treat HIV infection).

Inform the doctor or pharmacist if the patient is taking any of the following medicines:

• Ketoconazole, itraconazole, posaconazole, or voriconazole (used to treat fungal infections)
• Digoxin (used to treat heart rhythm disorders)
• Diazepam (used to treat anxiety, to reduce muscle tension, or to treat epilepsy)
• Phenytoin (used to treat epilepsy). If the patient is taking phenytoin, the doctor will need to monitor the patient's condition when starting and stopping Omeprazol Medreg.

• Tacrolimus (used in organ transplantation)
• St. John's Wort (Hypericum perforatum) (used to treat mild depression)

Frequency not known (cannot be estimated from the available data)

Low magnesium levels can cause fatigue, involuntary muscle contractions, disorientation, seizures, dizziness, or increased heart rate. If any of these symptoms occur, contact a doctor immediately. Low magnesium levels can also lead to low potassium or calcium levels in the blood. The doctor may recommend regular blood tests to monitor magnesium levels.
• A rash that may be associated with joint pain.

In very rare cases, Omeprazol Medreg may affect the number of white blood cells in the blood, leading to a lack of immunity. If the patient experiences an infection with symptoms such as fever with a significant worsening of general well-being or fever with signs of local infection, such as neck, throat, or mouth pain, or difficulty urinating, they should consult a doctor as soon as possible to rule out a lack of white blood cells (agranulocytosis) detected in a blood test. It is essential for the patient to receive complete information about the medicine.
