1. What Omeprazole Davur 20 mg is and what it is used for

Omeprazole Davur 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 Davur 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 may 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 may include reflux of stomach contents into 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.

2. What you need to know before you take Omeprazole Davur 20 mg

Do not take Omeprazole Davur

• if you are allergic to omeprazole or any of the other ingredients of this medicine (listed in section 6).
• if you are allergic to medicines that contain proton pump inhibitors (e.g., pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• if you are taking a medicine that contains nelfinavir (used to treat HIV infection).

If you are not sure, talk to your doctor or pharmacist before taking omeprazole.

Warnings and precautions

Talk to your doctor or pharmacist before taking omeprazole.

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

• You lose a lot of weight without any reason and have difficulty swallowing.
• You have stomach pain or indigestion.
• You start vomiting food or vomiting blood.
• Your stools are black (blood-stained feces).
• If you have severe or persistent diarrhea, as omeprazole has been associated with a slight increase in infectious diarrhea.
• You have severe liver problems.
• If you have ever had a skin reaction after treatment with a medicine similar to omeprazole to reduce stomach acid.
• If you get a skin rash, especially in areas of the skin exposed to the sun, consult your doctor as soon as possible, as it may be necessary to interrupt 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. The signs and symptoms may include decreased urine output or blood in the urine and/or hypersensitivity reactions such as fever, skin rash, and joint stiffness. You should report these signs to your doctor.

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

If you are taking proton pump inhibitors like omeprazole, 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).

Omeprazole may interfere with some diagnostic tests (chromogranin A). To avoid these interferences, treatment with omeprazole should be stopped at least five days before measurement.

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
• Numbness
• Pain in the tongue or red tongue, mouth ulcers
• Muscle weakness
• Altered vision
• Memory problems, confusion, depression

Taking Omeprazole Davur with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines. Omeprazole may affect the mechanism of action of some medicines, and some medicines may affect omeprazole.

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

Tell 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 you start or stop treatment with omeprazole
• Medicines used to prevent blood clots, such as warfarin or other vitamin K antagonists. Your doctor will need to monitor you when you start or stop treatment with omeprazole
• Rifampicin (used to treat tuberculosis)
• Atazanavir (used to treat HIV infection)
• Tacrolimus (in cases of organ transplantation)

Other adverse effects are:

Frequent Adverse Effects (may affect up to 1 in 10 people)

• Allergic reactions, sometimes very intense, 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.
• Taste disturbances.

• Inflammation of the mouth.

In very rare cases, omeprazole may affect the white blood cells in the blood and cause immunodeficiency. If you have an infection with symptoms such as fever with a severely deteriorated general condition or fever with symptoms of local infection, such as neck, throat, 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 that you provide information about the medication you are taking at that time.

Unknown Frequency (cannot be determined from available data)

• Inflammation of the intestine (which causes diarrhea).

• If you are taking omeprazole for more than three months, it is possible that magnesium levels in the blood may decrease. Low magnesium levels can cause fatigue, muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you have any of these symptoms, go to the 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.
