Warnings and precautions

Consult your doctor or pharmacist before starting to takeQuetiapina Alter:

• 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 takequetiapinebecause the group of medicines to whichquetiapinebelongs may increase the risk of stroke, or in some cases the risk of death, in these people.
• if you are an elderly person with Parkinson's disease/parkinsonism.
• if you or a family member has a history of blood clots, as medicines like these have been associated with the formation of blood clots.
• if you have or have had a condition in which your breathing is interrupted for short periods of time 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, a bowel 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 Alter").

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

• a combination of fever, intense muscle stiffness, sweating, or a decrease in level of 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, breathing 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, symptoms similar to flu, 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 bowel obstruction.
• Thoughts of suicide and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This may be more likely when you first start taking this medicine, 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 medicine suddenly. 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 behaviour in young adults under 25 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 behaviour.

• Drug reaction with eosinophilia and systemic symptoms (DRESS).

Generalised rash, high body temperature, elevated liver enzymes, blood abnormalities (eosinophilia), swollen lymph nodes, and other organs involved (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.
