If you notice any of the following rare but serious adverse effects, stop taking Nuclosina and consult your doctor immediately:

• Sudden whistling when breathing (sudden wheezing), swelling of the lips, tongue, and throat or body, skin rash, fainting or difficulty swallowing (severe allergic reaction).
• Redness of the skin with blistering or peeling. Intense blisters and bleeding may also appear on the lips, eyes, mouth, nose, and genitals. This could be "Stevens-Johnson syndrome" or "toxic epidermal necrolysis".
• Yellowing of the skin, dark urine, and fatigue, which can be symptoms of liver problems.

Adverse effects can occur with certain frequencies, which are defined as follows:

Other adverse effects are:

Frequent Adverse Effects

• Headache.
• Effects on the stomach or intestine: diarrhea, stomach pain, constipation, and gas (flatulence).
• Nausea or vomiting.
• Benign polyps in the stomach.

• Feeling that everything is spinning (vertigo).
• Abnormalities in blood tests that check liver function.
• Skin rash, hives, and itching.
• Feeling of general discomfort and lack of energy.

Rare Adverse Effects

• Blood problems, such as a decrease in white blood cells or platelets. This can cause weakness or bruising and increase the risk of infection.
• Allergic reactions, sometimes very intense, including swelling of the lips, tongue, and throat, fever, and wheezing.
• Low sodium levels in the blood. This can cause weakness, vomiting, and cramps.
• Agitation, confusion, or depression.
• Taste disturbances.
• Visual problems, such as blurred vision.
• Sudden feeling of difficult breathing (bronchospasm).
• Dry mouth.
• Inflammation of the mouth.
• Infection called "candidiasis" that can affect the intestine and is caused by a fungus.
• 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

• Abnormalities in blood counts, such as agranulocytosis (lack of white blood cells).
• Aggression.
• Seeing, feeling, or hearing things that do not exist (hallucinations).
• Severe liver problems that cause liver failure and brain inflammation.
• Sudden appearance of an intense rash, blistering, or peeling of the skin. This can be accompanied by high fever and joint pain (erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis).
• Muscle weakness.
• Enlargement of the breasts in males.

In very rare cases, Nuclosina 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.

With unknown frequency, it has been reported that:

• If you are taking Nuclosina for more than three months, it is possible that magnesium levels in the blood may decrease. Low magnesium levels can cause fatigue, muscle contractions, disorientation, convulsions, dizziness, and increased heart rate. If you experience any of these symptoms, consult your doctor immediately. Low magnesium levels can also produce a decrease in potassium and calcium levels in the blood. Your doctor may decide to perform periodic blood tests to monitor magnesium and calcium levels.
• Skin rash, possibly with joint pain.

Uncommon:

• If you are taking proton pump inhibitors like Nuclosina, especially for a period of more than one year, you may have a slightly increased risk of hip, wrist, and spine fractures. Inform your doctor if you have osteoporosis or if you are taking corticosteroids (which can increase the risk of osteoporosis).

Do not worry about this list of possible adverse effects. You may not experience any of them.
