1. What Omeprazol Viatris is and what it is used for

Omeprazol Viatris 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 is used to treat the following conditions:

In adults:

• "Gastroesophageal reflux disease" (GERD). In this disorder, stomach acid passes 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 passes into the esophagus (the tube connecting the throat to the stomach), causing pain, inflammation, and heartburn. In children, symptoms of the disease may include return of stomach contents into the mouth (regurgitation), vomiting, and inadequate 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 Viatris

Do not take Omeprazol Viatris

• 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 containing proton pump inhibitors (for example, pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• If you are taking a medicine containing 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 Omeprazol Viatris.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Omeprazol Viatris.

Serious skin adverse reactions have been reported with omeprazole treatment, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). Stop taking omeprazole and contact your doctor immediately if you experience any of these symptoms related to serious skin adverse reactions described in section 4.

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

• Unexplained significant weight loss and difficulty swallowing.
• Stomach pain or indigestion.
• New onset of vomiting food or vomiting blood.
• Black stools (blood-stained faeces).
• Severe or persistent diarrhoea, as omeprazole has been associated with a slight increase in infectious diarrhoea.
• 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 are scheduled to have a specific blood test (chromogranin A).

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

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

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 discontinue omeprazole treatment. Remember to mention any other symptoms you may notice, such as joint pain.

Kidney inflammation may occur while taking omeprazole. Signs and symptoms may include reduced urine volume or blood in the urine and/or hypersensitivity reactions such as fever, rash, and joint stiffness. You should report these signs to your treating doctor.

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
• Blurred vision
• Memory problems, confusion, depression

Children

Some children with chronic conditions may require long-term treatment, although this is not recommended. Do not give this medicine to children under 1 year of age or weighing <10 kg.

Other medicines and Omeprazol Viatris

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines. This includes medicines you obtain without a prescription. This is because omeprazole can affect how some medicines work, and some medicines can 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 the 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.

• Skin rash, hives and itching.
• General feeling of discomfort and lack of energy.

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

• Blood disorders, such as a decrease in white blood cells or platelets. This may cause weakness, bruising and increased risk of infections.
• 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 feeling of difficulty breathing (bronchospasm).

• Serious kidney problems (interstitial nephritis).
• Increased sweating.

Very rare (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).
• Severe liver problems leading to liver failure and brain inflammation.
• Erythema multiforme.
• Muscle weakness.
• Enlargement of the breasts in men.

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, your blood magnesium levels may decrease. Low magnesium levels may present as fatigue, involuntary muscle contractions, disorientation, seizures, dizziness or increased heart rate. If you experience any of these symptoms, inform your doctor immediately. Low magnesium levels may also lead to reduced levels of potassium or calcium in the blood. Your doctor may decide to perform periodic blood tests to monitor your magnesium levels.

• Rash, possibly with joint pain.

In very rare cases, omeprazole may affect white blood cells and cause immunodeficiency. If you develop an infection with symptoms such as fever accompanied by a very poor 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 medication you are taking at this time.
