6.Contents of the pack and additional information

Omeprazole cinfa 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).
• Omeprazolemay 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 omeprazole:

• If you are allergic to omeprazole or any of the other components of this medication (listed in section 6).
• 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).

Do not take omeprazole if you fall into any of the above categories. If you are unsure, speak with your doctor or pharmacist before taking omeprazole.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Omeprazole Cinfa 40 mg:

Severe cutaneous reactions have been reported in relation to omeprazole treatment, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized pustular psoriasis (AGPP). Stop taking omeprazole and consult your doctor immediately if you experience any of these symptoms related to severe cutaneous reactions described in section 4.

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

• Unexplained weight loss and difficulty swallowing.
• Abdominal pain or indigestion.
• Starting to vomit food or blood.
• Black stools (blood-stained feces).
• Severe or persistent diarrhea, as omeprazole has been associated with a slight increase in infectious diarrhea.
• Severe liver problems.
• If you have ever had a skin reaction after treatment with a similar medication to omeprazole cinfa for reducing stomach acid.
• If you are scheduled to have a specific blood test (Cromogranin A).

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

Taking a proton pump inhibitor like omeprazole, especially for more than a year, may slightly increase the risk of fractures in the hip, wrist, or spine. Inform your doctor if you have osteoporosis or are taking corticosteroids (which can increase the risk of osteoporosis).

Omeprazole may cause kidney inflammation. 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. Inform your doctor of these signs.

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

Children

Some children with chronic diseases may require long-term treatment, although it is not recommended. Do not administer this medication to children under 1 year of age or <10>

Your doctor may decide to perform periodic blood tests to monitor your magnesium levels.

In very rare cases, omeprazole cinfa may affect white blood cells in the blood and cause immunodeficiency. If you have an infection with symptoms such as fever with a very deteriorated general condition or fever with symptoms of local infection, 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.
