Warnings and precautions

Consult your doctor or pharmacist before starting to take this medication::

• if you, or a family member, have or have had any heart problems, such as irregular heart rhythms, heart muscle weakness, or heart inflammation, or if you are taking any medication that may affect your heart rate
• if you have low blood pressure
• if you have had a stroke, especially if you are elderly
• if you have liver problems
• if you have ever had a seizure (convulsion)
• if you have diabetes or are at risk of developing diabetes. Your doctor may monitor your blood sugar levels while you are taking quetiapine
• if you know you have had low white blood cell counts (which may or may not have been caused by other medications)
• if you are an elderly person with dementia (loss of brain function). Do not take quetiapine because the group of medications to which quetiapine belongs may increase the risk of stroke or death in these people
• if you are an elderly person with Parkinson's disease or parkinsonism
• if you or a family member has a history of blood clots, as medications like these have been associated with blood clot formation
• if you have or have had a condition in which your breathing is interrupted for short periods during normal nighttime sleep (called sleep apnea) and are taking medications that decrease normal brain activity (depressants)
• if you have or have had a condition in which you cannot completely empty your bladder (urinary retention), have an enlarged prostate, intestinal obstruction, or high pressure inside your eye. These conditions may be caused by medications (called anticholinergics) that affect how nerve cells work, to treat certain medical conditions
• if you have a history of alcohol or drug abuse
• If you have depression or other conditions treated with antidepressants

The use of these medications with Quetiapina Qualigen Medica may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications and Quetiapina Qualigen Medica").

Inform your doctor immediately if after taking quetiapine you experience any of the following:

• A combination of fever, intense muscle stiffness, sweating, or a decrease in consciousness (a condition called neuroleptic malignant syndrome). You may need immediate medical treatment
• Uncontrolled movements, mainly of your face or tongue
• Dizziness or feeling very drowsy. This may increase the risk of accidental injuries (falls) in elderly patients
• Seizures (convulsions)
• Prolonged and painful erection (priapism)
• Fast and irregular heartbeats, even when at rest, palpitations, respiratory problems, chest pain, or unexplained fatigue. Your doctor should examine your heart and, if necessary, refer you to a cardiologist immediately

These conditions may be caused by this type of medication.

Inform your doctor as soon as possible if you have:

• Fever, symptoms similar to the flu, sore throat, or any other infection, as it may be a consequence of a very low white blood cell count and require discontinuation of quetiapine treatment and/or additional treatment
• Constipation with persistent abdominal pain, or constipation that has not responded to treatment, as it may lead to a more severe intestinal blockage
• Thoughts of suicide and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This may increase at the beginning of treatment, as all these medications take time to take effect, usually around two weeks but sometimes longer. These thoughts may also increase if you stop taking your medication abruptly. You may be more likely to think this way if you are a young adult. Information from clinical trials has shown an increased risk of thoughts of suicide and/or suicidal behavior in adults under 25 with depression.

If you ever think about harming yourself or committing suicide, contact your doctor or go to the hospital immediately. It may help to tell a close family member or friend that you are depressed, and ask them to read this leaflet. You can ask them to tell you if they think your depression is getting worse, or if they are concerned about changes in your behavior.

• Drug reaction with eosinophilia and systemic symptoms (DRESS)

Generalized rash, elevated body temperature, elevated liver enzymes, blood abnormalities (eosinophilia), swollen lymph nodes, and other affected organs (drug reaction with eosinophilia and systemic symptoms, also known as DRESS).

If you develop these symptoms, stop using quetiapine and contact your doctor or seek medical attention immediately.
