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

Omeprazole 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” (GORD). In this condition, acid from the stomach escapes into the gullet (the tube which connects the throat to the stomach), causing pain, inflammation, and heartburn.
• Ulcers in the upper part of the intestine (duodenal ulcer) or stomach (gastric ulcer).
• Ulcers caused by a bacteria 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 non-steroidal anti-inflammatory drugs (NSAIDs). Omeprazole may also be used to prevent ulcers if you are taking NSAIDs.
• Too much 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 escapes into the gullet (the tube which connects the throat to the stomach), causing pain, inflammation, and heartburn. In children, the symptoms of the disease can include the return of stomach contents into the mouth (regurgitation), vomiting, and insufficient weight gain.

Children over 4 years of age and adolescents

• Ulcers caused by a bacteria 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 Viatris

Do not take Omeprazole 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 (e.g., pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• If you are taking a medicine that contains nelfinavir (used to treat HIV infection).

Do not take omeprazole if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Omeprazole Viatris.

Warnings and precautions

Tell your doctor or pharmacist before taking Omeprazole Viatris.

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

Omeprazole may mask the symptoms of other diseases. Therefore, if you experience any of the following before or while taking omeprazole, contact your doctor immediately:

• Unintentional weight loss and difficulty swallowing.
• Stomach pain or indigestion.
• Vomiting food or blood.
• Black stools (blood-stained stools).
• If you have 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 medicine similar to omeprazole to reduce stomach acid.
• If you are due to have a specific blood test (Chromogranin A).

If you take omeprazole for a long period (more than 1 year), your doctor will probably keep you under regular surveillance. You should report any new and unusual symptoms to your doctor, especially if you have been taking omeprazole for a long time.

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

If you get a rash on your skin, especially in areas exposed to the sun, you should contact your doctor as soon as possible, as you may need to stop your treatment with omeprazole. Also, remember to mention any other symptoms you might notice, such as joint pain.

When taking omeprazole, kidney inflammation can occur. The signs and symptoms may include decreased urine output or blood in the urine and/or hypersensitivity reactions such as fever, rash, and joint stiffness. You should inform your doctor of these signs.

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 levels of vitamin B12:

• Extreme tiredness or lack of energy
• Numbness
• Pain in the tongue or red tongue, mouth ulcers
• Muscle weakness

Your doctor may decide to perform periodic blood tests to monitor your magnesium levels.
• Rash, possibly with joint pain.

In very rare cases, omeprazole can 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.
