• Low sodium levels in the blood. This can cause weakness, vomiting, and cramps.
• Agitation, confusion, or depression.

• Liver problems, such as jaundice, which can cause yellowing of the skin, dark urine, and fatigue.
• Hair loss (alopecia).
• Skin rash with exposure to sunlight.
• Joint pain (arthralgias) or muscle pain (myalgias).
• Severe kidney problems (interstitial nephritis).
• Increased sweating.

Very Rare Adverse Effects(may affect up to 1 in 10,000 people)

• Blood count alterations, such as agranulocytosis (lack of white blood cells).
• Aggression.
• Seeing, feeling, or hearing things that do not exist (hallucinations).

Frequency Not Known(cannot be estimated from available data)

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

• Skin rash, possibly with joint pain.

In very rare cases, Omeprazol STADA 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.
