Your doctor may continue prescribing quetiapine even when you are feeling better.

•if you are taking any of the following medicines:

• some medicines for HIV
• azole-type medicines (for fungal infections)
• erythromycin or clarithromycin (for infections)
• nefazodone (for depression).

If you are unsure, consult your doctor or pharmacist before taking quetiapine.

Warnings and precautions

Consult your doctor or pharmacist before starting to take quetiapine

•if you, or a family member, have or have had any heart problems, for example, irregular heart rhythm, heart muscle weakness, or heart inflammation, or if you are taking any medicine that may affect your heart rhythm.

•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 that you have had low white blood cell counts (which may or may not have been caused by other medicines).

•if you are an elderly person with dementia (loss of brain function). If so, do not take quetiapine because the group of medicines to which quetiapine belongs may increase the risk of stroke or, in some cases, 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 medicines 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 sleep (called "sleep apnea") and are taking medicines 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 medicines (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 that are treated with antidepressants. The use of these medicines with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see "Other medicines and Quetiapina Stada").

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).

•a prolonged and painful erection (priapism).

•rapid 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 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 a 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, sometimes you may 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 years old with depression.

If at any time you think about harming yourself or committing suicide, contact your doctor or go to a 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.

Severe skin reactions (SCARs)

Very rarely, with the use of this medicine, severe skin reactions (SCARs) have been reported, which may put your life at risk or be fatal. These usually manifest as:

• Stevens-Johnson syndrome (SSJ), a generalised rash with blisters and skin peeling, particularly around the mouth, nose, eyes, and genitals.
• Toxic epidermal necrolysis (NET), a more severe form that causes extensive skin peeling.
• Drug reaction with eosinophilia and systemic symptoms (DRESS), which consists of flu-like symptoms with a rash, fever, swollen lymph nodes, and abnormal blood test results (including an increase in white blood cell count (eosinophilia) and elevated liver enzymes).

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