1. What Omeprazole Qualigen is and what it is used for
Omeprazole Qualigen contains the active substance omeprazole. It belongs to a group of medicines called “proton pump inhibitors”. These medicines work by reducing the amount of acid produced by the stomach.
Omeprazole Qualigen is used to treat the following conditions:
In adults:
- “Gastroesophageal reflux disease” (GORD). In this condition, acid from the stomach passes into the esophagus (the tube that connects the throat to the stomach), causing pain, inflammation, and heartburn.
- Ulcers in the upper part of the intestine (duodenal ulcer) or in the stomach (gastric ulcer).
- Ulcers infected by a bacterium called “Helicobacter pylori”. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
- Ulcers caused by medicines called NSAIDs (non-steroidal anti-inflammatory drugs). Omeprazole Qualigen can also be used to prevent ulcers if you are taking NSAIDs.
- Excess acid in the stomach caused by a tumor in the pancreas (Zollinger-Ellison syndrome).
In children:
Children over 1 year of age and=10 kg
- “Gastroesophageal reflux disease” (GORD). In this condition, acid from the stomach passes into the esophagus (the tube that connects the throat to the stomach), causing pain, inflammation, and heartburn. In children, the symptoms of the disease can include return of stomach contents to the mouth (regurgitation), vomiting, and insufficient weight gain.
Children over 4 years of age and adolescents
- Ulcers infected by a bacterium called “Helicobacter pylori”. If your child has this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

Low magnesium levels can cause fatigue, muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you experience any of these symptoms, consult your doctor immediately. Low magnesium levels can also cause a decrease in blood potassium and calcium levels. Your doctor may decide to perform periodic blood tests to monitor magnesium levels.
If you are taking proton pump inhibitors like Omeprazol Qualigen 20 mg, especially for a period of more than one year, you may have a slightly increased risk of hip, wrist, and spine fractures. Inform your doctor if you have osteoporosis or if you are taking corticosteroids (which can increase the risk of osteoporosis).
