6.Further information

Omeprazol Normon contains the active ingredient omeprazole. It belongs to a group of medicines called “proton pump inhibitors”. These medicines act by reducing the amount of acid produced by the stomach.

Omeprazole is used to treat the following diseases:

In adults:

• “Gastroesophageal reflux disease” (GERD). In this disorder, stomach acid passes into the esophagus (the tube that connects the throat with the stomach), causing pain, inflammation, and heartburn.
• Ulcers in the upper part of the small intestine (duodenal ulcer) or in the stomach (gastric ulcer).
• Ulcers infected by a bacteria called “Helicobacter pylori”. If you have this disease, it is possible that your doctor will prescribe antibiotics to treat the infection and allow the ulcer to heal.
• Ulcers caused by certain medicines called NSAIDs (nonsteroidal anti-inflammatory drugs). Omeprazole may also be used to prevent the formation of 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” (GERD). In this disorder, stomach acid passes into the esophagus (the tube that connects the throat with the stomach), causing pain, inflammation, and heartburn.
  In children, the symptoms of the disease may include the return of stomach contents to the mouth (regurgitation), vomiting, and inadequate weight gain.

Children over 4 years of age and adolescents

• Ulcers infected by a bacteria called “Helicobacter pylori”. If your child has this disease, it is possible that your doctor will prescribe antibiotics to treat the infection and allow the ulcer to heal.

Do not take Omeprazol Normon

• if you are allergic (hypersensitive) to omeprazole or any of the other components of omeprazole.
• if you are allergic to medications that contain proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• if you are taking a medication that contains nelfinavir (used for HIV infection).

If you are unsure, speak with your doctor or pharmacist before taking omeprazole.

Be especially careful with Omeprazol Normon

Omeprazole may mask the symptoms of other diseases.Therefore, if you experience any of the following symptoms before starting to take this medication or during treatment, consult your doctor immediately:

• You lose weight significantly without apparent reason and have trouble swallowing.
• You have stomach pain or indigestion.
• You start vomiting food or blood.
• Your stools are black (blood-stained stools).
• You have severe or persistent diarrhea, as omeprazole has been associated with a slight increase in infectious diarrhea.
• You have severe liver problems.
• You have had a skin reaction after treatment with a similar medication to omeprazole for reducing stomach acid.

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

If you take omeprazole for a long period (more than 1 year), your doctor will likely perform regular check-ups. You should inform your doctor of any new or unusual symptoms and circumstances whenever you visit.

Like all medications, omeprazole may cause side effects, although not everyone will experience them.

If you experience any of the following rare but serious side effects, stop taking omeprazole and consult your doctor immediately:

• Sudden hissing sounds while breathing (sudden onset of bronchospasm), swelling of the lips, tongue, and throat or body, skin rash, dizziness, or difficulty swallowing (severe allergic reaction).
• Redness of the skin with blistering or peeling. Blisters may also appear on the lips, eyes, mouth, nose, and genitals. This could be "Stevens-Johnson syndrome" or "toxic epidermal necrolysis."
• Yellowing of the skin, dark urine, and fatigue, which may be symptoms of liver problems.

Side effects may occur with certain frequencies, which are defined as follows:

Other side effects are:

Common side effects

• Headache.
• Effects on the stomach or intestines: diarrhea, stomach pain, constipation, and gas (flatulence).
• Nausea or vomiting.
• Benign polyps in the stomach.

Uncommon side effects

• Swelling of the feet and ankles.
• Sleep disturbances (insomnia).
• Dizziness, tingling, drowsiness.
• Sensation of spinning (vertigo).
• Abnormal blood test results that check liver function.
• Skin rash, hives, and itching.
• General feeling of discomfort and lack of energy.

Rare side effects

• Blood disorders, such as a decrease in white blood cells or platelets. This can cause weakness or bruising and increase the risk of infections.
• Allergic reactions, sometimes very severe, including swelling of the lips, tongue, and throat, fever, and wheezing.
• Low sodium levels in the blood. This can cause weakness, vomiting, and muscle cramps.
• Agitation, confusion, or depression.
• Changes in taste.
• Visual problems, such as blurred vision.
• Sudden sensation of difficulty breathing (bronchospasm).
• Dry mouth.
• Inflammation of the inside of the mouth.
• Infection called "candidiasis" that can affect the intestines and is caused by a fungus.
• Liver problems, such as jaundice, which can cause yellowing of the skin, dark urine, and fatigue.
• Hair loss (alopecia).
• Skin rash with exposure to sunlight.
• Joint pain (arthralgias) or muscle pain (myalgias).
• Severe kidney problems (interstitial nephritis).
• Increased sweating.

Very rare side effects

• Blood count abnormalities, such as agranulocytosis (lack of white blood cells).
• Aggression.
• Seeing, feeling, or hearing things that do not exist (hallucinations).
• Severe liver problems that cause liver failure and inflammation of the brain.
• Sudden onset of a severe rash, blistering, or peeling of the skin. This may be accompanied by high fever and joint pain (erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis).
• Muscle weakness.
• Enlargement of the breasts in men.

In very rare cases, omeprazole may affect white blood cells in the blood and cause immunodeficiency. If you have an infection with symptoms such as fever with a general state of deterioration or fever with local infection symptoms, such as neck pain, throat pain, or mouth pain or difficulty urinating, you should consult your doctor as soon as possible to perform a blood test and rule out a lack of white blood cells (agranulocytosis). It is essential to provide information about the medication you are taking at that time.

Side effects of unknown frequency

If you are takingomeprazole 40 mg hard gastro-resistant capsulesfor more than three months, it is possible that magnesium levels in the blood may decrease. Low magnesium levels can cause fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you experience any of these symptoms, see your doctor immediately. Low magnesium levels can also cause a decrease in potassium and calcium levels in the blood. Your doctor may decide to perform periodic blood tests to monitor magnesium levels.

Skin rash, possibly with joint pain.

If you are taking proton pump inhibitors such asomeprazole 40mg hard gastro-resistant capsules, especially for a period of more than one year, you may slightly increase the risk of hip, wrist, or spinal fractures. Inform your doctor if you have osteoporosis or if you are taking corticosteroids (they can increase the risk of osteoporosis).
