1. What is Omeprazole Medreg and what is it used for
Omeprazole 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.
Omeprazole 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). Omeprazole Medreg can also be used to prevent the development of ulcers when taking NSAIDs.
- Excessive stomach acid production due to 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 Omeprazole Medreg
When not to take Omeprazole Medreg:
- If the patient has been diagnosed with an allergy (hypersensitivity) to omeprazole or any of the other ingredients of Omeprazole 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 Omeprazole Medreg if any of the above situations apply to the patient. Before starting to take Omeprazole Medreg, discuss this with a doctor or pharmacist.
Warnings and precautions

In connection with the treatment with Omeprazole 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 Omeprazole Medreg and seek medical help immediately.

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.
- Skin rash that can occur with joint pain.
In very rare cases, Omeprazole 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 a 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.
