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

Omeprazole Normon contains the active ingredient omeprazole. It belongs to a group of medications called "proton pump inhibitors". These medications work 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 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 disease, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
• Ulcers caused by medications called NSAIDs (non-steroidal anti-inflammatory drugs).

Omeprazole can 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 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 disease, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

2. Before taking Omeprazole Normon

Do not take Omeprazole 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 to treat HIV infection).

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

Be careful with Omeprazole Normon

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

• Losing a lot of weight without apparent reason and having trouble swallowing.
• Having stomach pain or indigestion.
• Starting to vomit food or vomiting blood.
• Having black stools (stools stained with blood).
• If you have severe or persistent diarrhea, as omeprazole has been associated with a slight increase in infectious diarrhea.
• Having severe liver problems.
• If you have ever had a skin reaction after treatment with a medication similar to omeprazole to reduce stomach acidity.

• If you suffer 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 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 periodic check-ups. You should report any new or unusual symptoms and circumstances whenever you visit your doctor.

Use of other medications

Tell your doctor or pharmacist if you are using or have recently used other medications, including those purchased without a prescription. Omeprazole can affect the mechanism of action of some medications, and some medications can affect omeprazole.

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

Tell your doctor or pharmacist if you are taking any of the following medications:

• Ketoconazole, itraconazole, 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.
• Medications 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).
• 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).

If your doctor has also prescribed the antibiotics amoxicillin and clarithromycin to treat ulcers caused by Helicobacter pyloriinfection, it is very important that you inform them of the other medications you are taking.
