1. What Omeprazol Davur 10 mg is and what it is used for

Omeprazol Davur contains the active substance omeprazole. It belongs to a group of medicines known as "proton pump inhibitors". These medicines work by reducing the amount of acid produced by the stomach.

Omeprazol Davur 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 a group of 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 flows back 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 poor weight gain.

Children over 4 years of age and adolescents

Ulcers infected with 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.

2. What you need to know before taking Omeprazol Davur 10 mg

Do not take Omeprazol Davur

• if you are allergic to omeprazole 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. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• if you are taking a medicine containing nelfinavir (used for HIV infection).

If you are unsure, talk to your doctor or pharmacist before taking omeprazole.

Warnings and precautions

Talk to your doctor or pharmacist before taking omeprazole.

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

• You lose weight significantly without 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 diarrhoea, as omeprazole has been associated with a slight increase in infectious diarrhoea.
• You have severe liver problems.
• If you have ever had a skin reaction after treatment with a medicine similar to omeprazole used to reduce stomach acid.
• 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 stop treatment with omeprazole. Remember to mention any other symptoms you may notice, such as joint pain.
• You are scheduled to have a specific blood test (chromogranin A).

When taking omeprazole, kidney inflammation 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 should report these signs to your treating doctor.

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

If you are taking proton pump inhibitors such as omeprazole, especially for more than one year, there may be a slight increase in the risk of fractures of the hip, wrist, and spine. Inform your doctor if you have osteoporosis or are taking corticosteroids (which may increase the risk of osteoporosis).

Omeprazole may interfere with certain diagnostic tests (chromogranin A). To avoid such interference, omeprazole treatment should be discontinued at least five days before measurement.

This medicine may affect how 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 vitamin B12 levels:

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

Taking Omeprazol Davur with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines. Omeprazole may affect how some medicines work, and some medicines may 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
• Medicines used to prevent blood clots, such as warfarin or other vitamin K antagonists. Your doctor will need to monitor you when starting or stopping omeprazole treatment
• Rifampicin (used to treat tuberculosis)
• Atazanavir (used to treat HIV infection)
• Tacrolimus (used in organ transplantation)
• St. John’s wort (Hypericum perforatum) (used to treat mild depression)
• Cilostazol (used to treat intermittent claudication)
• Saquinavir (used to treat HIV infection)
• Clopidogrel (used to prevent blood clots (thrombi))
• Erlotinib (used to treat cancer)
• Methotrexate (a chemotherapy medicine used in high doses to treat cancer). If you are taking a high dose of methotrexate, your doctor will need to temporarily stop omeprazole treatment.

If your doctor has prescribed you antibiotics amoxicillin and clarithromycin in addition to omeprazole to treat ulcers caused by Helicobacter pylori infection, it is very important that you inform them about any other medicines you are taking.

• General feeling of discomfort and lack of energy

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

• Blood problems, such as a decrease in white blood cells or platelets. This may cause weakness or bruising and increase the likelihood of developing infections.
• Allergic reactions, sometimes severe, including swelling of the lips, tongue and throat, fever and wheezing.
• Low sodium levels in the blood. This may cause weakness, vomiting and cramps.
• Restlessness, confusion or depression.
• Taste disturbances.
• Vision problems, such as blurred vision.
• Sudden sensation of difficulty breathing (bronchospasm).
• Dry mouth.
• Inflammation inside the mouth.
• Fungal infection called “candidiasis” affecting the intestine.

• Hair loss (alopecia).
• Skin rash upon exposure to sunlight.
• 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 real (hallucinations).
• Serious liver problems leading to liver failure and brain inflammation.
• Erythema multiforme.
• Muscle weakness.
• Enlargement of the breasts in men.

In very rare cases, omeprazole may affect the white blood cells and cause immunodeficiency. If you develop an infection with symptoms such as fever accompanied by a severely unwell general condition, or fever with signs of local 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 medicines you are taking at this time.

Frequency not known (cannot be estimated from available data)

• Inflammation in the intestine (causing diarrhoea).

• If you are taking omeprazole for more than three months, magnesium levels in the blood may decrease. Low magnesium levels can cause fatigue, involuntary muscle contractions, disorientation, seizures, dizziness, and increased heart rate. If you experience any of these symptoms, consult your doctor immediately. Low magnesium levels may also lead to decreased levels of potassium and calcium in the blood. Your doctor may decide to perform periodic blood tests to monitor magnesium levels.

• Skin rash, possibly with joint pain
