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

Omeprazol Normon 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 is used to treat the following conditions:

In adults:

"Gastroesophageal reflux disease" (GERD). In this disorder, 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 intestine (duodenal ulcer) or in the stomach (gastric ulcer).
• Ulcers infected with 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 may also be used to prevent the formation of ulcers if you are taking NSAIDs.

• Excess stomach acid 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 connecting the throat to the stomach), causing pain, inflammation, and heartburn. In children, symptoms of the disease may include regurgitation of stomach contents into the mouth, vomiting, and inadequate weight gain.

Children over 4 years of age and adolescents

Ulcers infected with a bacterium called "Helicobacter pylori". If your child has this condition, the doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

2. What you need to know before starting to take Omeprazol Normon

Do not take Omeprazol Normon:

• If you are allergic to omeprazol or to any of the other components of this medicine (listed in section 6).
• If you are allergic to medicines containing proton pump inhibitors (e.g. pantoprazol, lansoprazol, rabeprazol, esomeprazol).
• If you are taking a medicine containing nelfinavir (used for HIV infection).

Do not take Omeprazol Normon if any of the above apply to you. If you are unsure, talk to your doctor or pharmacist before taking Omeprazol Normon.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Omeprazol Normon.

Serious skin adverse reactions have been reported in association with omeprazole treatment, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). Discontinue omeprazole and consult your doctor immediately if you experience any of these symptoms related to serious skin adverse reactions described in section 4.

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

• You lose weight significantly without apparent reason and have difficulty swallowing.
• You have stomach pain or indigestion.
• You start vomiting food or vomiting blood.
• Your bowel movements 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 ever had a skin reaction after treatment with a medicine similar to omeprazole for reducing stomach acidity.
• You are scheduled to have a specific blood test (chromogranin A).

If you take omeprazole for a long period (more than 1 year), your doctor will likely perform periodic check-ups. You must report any new or unusual symptoms or circumstances during each visit to your doctor.

Taking a proton pump inhibitor such as Omeprazol Normon, especially for more than one year, may slightly increase the risk of fractures of the hip, wrist, or spine.

Inform your doctor if you have osteoporosis or if you are taking corticosteroids (which may increase the risk of osteoporosis).

If you develop a skin rash, especially in areas of skin exposed to sunlight, consult your doctor as soon as possible, as it may be necessary to discontinue treatment with omeprazole. Remember to mention any other symptoms you may notice, such as joint pain.

When taking omeprazole, inflammation of the kidney may occur. Signs and symptoms may include decreased urine volume or blood in the urine and/or hypersensitivity reactions such as fever, skin rash, and joint stiffness. You must report these signs to your treating doctor.

This medicine may affect the way your body absorbs vitamin B12, especially if you need to take it for a long time. Contact your doctor if you notice any of the following symptoms, which could indicate low levels of vitamin B12:

• Extreme tiredness or lack of energy
• Tingling
• Tongue pain or red, sore tongue, mouth ulcers
• Muscle weakness
• Altered vision
• Memory problems, confusion, depression

Children

Some children with chronic conditions may require long-term treatment, although this is not recommended. Do not administer this medicine to children under 1 year of age or weighing <10 kg.

Other medicines and Omeprazol Normon

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription. This is because omeprazole can affect the action of some medicines, and some medicines can affect omeprazole.

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

Inform your doctor or pharmacist if you are taking any of the following medicines:

• Ketoconazole, itraconazole, posaconazole, or voriconazole (used to treat fungal infections).
• Digoxin (used to treat heart problems).
• Diazepam (used to treat anxiety, relax muscles, or in epilepsy).
• Phenytoin (used in epilepsy). If you are taking phenytoin, your doctor will need to monitor you when starting or stopping omeprazole treatment.

• Abnormalities in blood tests used to check liver function.
• Skin rash, hives, and itching.
• General feeling of malaise and lack of energy.

Rare adverse effects (may affect up to 1 in 1,000 people)

• Blood problems, such as decreased white blood cells or platelets. This may cause weakness or bruising and increase the likelihood of developing infections.
• Low sodium levels in the blood. This may cause weakness, vomiting, and cramps.
• Restlessness, confusion, or depression.
• Taste disturbances.
• Visual problems, such as blurred vision.
• Sudden sensation of difficult breathing (bronchospasm).
• Dry mouth.
• Inflammation inside the mouth.
• Fungal infection called “candidiasis” that may affect the intestine.
• Hair loss (alopecia).

• Joint pain (arthralgia) or muscle pain (myalgia).
• Serious kidney problems (interstitial nephritis).
• Increased sweating.

Very rare adverse effects (may affect up to 1 in 10,000 people)

• Blood count abnormalities, such as agranulocytosis (lack of white blood cells).
• Aggressiveness.
• Seeing, feeling, or hearing things that are not there (hallucinations).
• Serious liver problems leading to liver failure and brain inflammation.
• Erythema multiforme.
• Muscle weakness.
• Enlargement of the breasts in males.

Frequency not known (cannot be estimated from available data)

• Inflammation in the intestine (causing diarrhea).
• If you are being treated with omeprazole for more than three months, your blood magnesium levels may decrease. Low magnesium levels may present as fatigue, involuntary muscle contractions, disorientation, seizures, dizziness, or increased heart rate. If you experience any of these symptoms, inform your doctor immediately. Low magnesium levels may also lead to reduced levels of potassium or calcium in the blood. Your doctor may decide to carry out periodic blood tests to monitor your magnesium levels.
• Rash, possibly with joint pain.

In very rare cases, omeprazol may affect white blood cells and cause immunodeficiency. If you develop an infection with symptoms such as fever accompanied by a very poor general condition, or fever with signs of localized infection such as neck, throat or mouth pain, or difficulty urinating, you should consult your doctor as soon as possible for a blood test to rule out a deficiency in white blood cells (agranulocytosis). It is important that you inform your doctor about any medication you are currently taking.
