Read this leaflet carefully before you start taking this medicine.

• Keep this leaflet, as you may need to read it again.
• If you have any questions, ask your doctor or pharmacist.

• If you experience any side effects, consult your doctor or pharmacist, even if they are not listed in this leaflet. See section 4.

Dolintol contains the active ingredient 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.

Dolintol 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 burning.
• 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). Dolintol 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 weighing = 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 burning.

In children, 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 Dolintol

• if you are allergic to omeprazole or any of the other ingredients 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 Dolintol if you fall into any of the above cases. If you are unsure, consult your doctor or pharmacist before taking Dolintol.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Dolintol.

Severe skin 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 Dolintol and consult your doctor immediately if you experience any of these symptoms related to severe skin reactions described in section 4.

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

• you lose weight significantly without apparent reason and have trouble swallowing.
• you have stomach pain or indigestion.
• you start vomiting food or blood.
• your stools are black (blood-stained stools).

• you have ever had a skin reaction after treatment with a similar medication to Dolintol for reducing stomach acid.

• you are scheduled to have a specific blood test (Cromogranin A).

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

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

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.

This medication 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 may indicate low vitamin B12 levels:

Low magnesium levels can manifest as fatigue, involuntary muscle contractions, disorientation, seizures, dizziness, or increased heart rate.

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

• Skin rash, possibly with joint pain.

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