• You have low blood pressure.
• You have had a stroke, especially if you are elderly.
• You have liver problems.
• You have had a seizure (convulsion).
• You have diabetes or are at risk of developing diabetes. Your doctor may monitor your blood sugar levels while you are taking quetiapine.
• You know that you have had low white blood cell counts (which may or may not have been caused by other medicines).
• You are an elderly person with dementia (loss of brain function). If so, do not take quetiapine because the group of medicines to which Quetiapina Qualigen belongs may increase the risk of stroke or, in some cases, death in these people.
• You or a family member has a history of blood clots, as medicines like these have been associated with the formation of blood clots.
• You have depression or other conditions that are treated with antidepressants.

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

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

• A combination of fever, intense muscle stiffness, sweating, or a decrease in consciousness (a condition known as “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).
• A prolonged and painful erection (priapism).
• Fast and irregular heartbeats, even when at rest, palpitations, respiratory problems, chest pain, or unexplained fatigue. Your doctor will examine your heart and, if necessary, refer you to a cardiologist immediately.

These conditions may be caused by this type of medicine.

Inform your doctor as soon as possible if you have:

• Fever, flu-like symptoms, sore throat, or any other infection, as it could 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 medicines take time to work, 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 young 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 may ask them to tell you if they think your depression is getting worse, or if they are concerned about changes in your behavior.
