1. What is Quetiapine pensa and what is it used for

This medicine contains a substance called quetiapine. It belongs to a group of medicines known as antipsychotics. This medicine can be used to treat several conditions, such as:

• Bipolar depression and major depressive episodes in major depressive disorder: where you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite, or are unable to sleep.
• Mania: where you may feel highly excited, euphoric, agitated, enthusiastic, or hyperactive, or have poor judgment, which may include aggressive or violent behavior.
• Schizophrenia: where you may hear or sense things that are not there, believe things that are not true, or feel abnormally suspicious, anxious, confused, guilty, tense, or depressed.

When this medicine is being used to treat major depressive episodes in major depressive disorder, it will be taken in addition to another medicine you are using for this condition.

Your doctor may continue prescribing this medicine even after you start feeling better.

2. What you need to know before taking Quetiapina pensa

Do not take Quetiapina pensa:

• if you are allergic to quetiapine or to any of the other ingredients of this medicine (listed in section 6)
• 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 have any doubts, consult your doctor or pharmacist before taking this medicine.

Warnings and precautions

Consult your doctor or pharmacist before starting quetiapine:

• if you, or a family member, have or have had any heart problems, for example, heart rhythm problems, weakening of the heart muscle, or inflammation of the heart, or if you are taking any medicine that may affect your heartbeat.
• 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. If so, your doctor may monitor your blood sugar levels while you are taking this medicine.
• if you know you have previously had low levels of white blood cells (which may or may not have been caused by other medicines).
• if you are an elderly person with dementia (loss of brain functions). In this case, you should not take quetiapine, because the group of medicines to which quetiapine belongs may increase the risk of stroke, or in some cases the risk of death, in these individuals.
• 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 such as this have been associated with blood clot formation.
• if you have or have had a condition in which your breathing stops for short periods during normal nighttime sleep (called “sleep apnea”) and you are taking medicines that reduce 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 increased pressure inside your eye. These conditions can sometimes be caused by medicines (called “anticholinergics”) that affect how nerve cells function, used to treat certain medical conditions.
• if you have a history of alcohol or drug abuse.
• If you suffer from depression or other conditions treated with antidepressants. The use of these medicines together with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Quetiapina pensa”).

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

• A combination of fever, severe muscle stiffness, sweating, or decreased level of consciousness (a disorder known as “neuroleptic malignant syndrome”). Immediate medical treatment may be necessary.
• Uncontrollable movements, mainly of your face or tongue.
• Dizziness or feeling very drowsy. This may increase the risk of accidental injury (falls) in elderly patients.
• Seizures (convulsions).
• A prolonged and painful erection (priapism).
• Fast or irregular heartbeats, even at rest, palpitations, breathing problems, chest pain, or unexplained tiredness. Your doctor should examine your heart and, if necessary, refer you immediately to a cardiologist.

These disorders 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 this could be due to a very low count of white blood cells and may require discontinuation of quetiapine treatment and/or additional treatment.
• Constipation together with persistent abdominal pain, or constipation that has not responded to treatment, as this could lead to a more serious intestinal blockage.
• Suicidal thoughts and worsening of your depression.

If you are depressed, you may sometimes think about harming yourself or committing suicide. This risk may increase at the beginning of treatment, as all these medicines take time to work—usually about two weeks, but sometimes longer. These thoughts may also increase if you suddenly stop taking your medication. You may be more likely to have such thoughts if you are a young adult. Data from clinical trials have shown an increased risk of suicidal thoughts and/or suicidal behaviour in young adults under 25 years of age 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 let you know if they think your depression is getting worse or if they are concerned about changes in your behaviour.

• Drug rash with eosinophilia and systemic symptoms (DRESS). Widespread rash, high body temperature, elevated liver enzymes, blood abnormalities (eosinophilia), enlarged lymph nodes, and involvement of other organs (drug rash 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.

Other medicines and Quetiapina pensa

Tell your doctor if you are taking, have recently taken, or might need to take any other medicine.

Do not take this medicine if you are using any of the following medicines:

• Some medicines for HIV.
• Azole-type medicines (for fungal infections).

• Medicines that may cause constipation.
• Medicines (called “anticholinergics”) that affect how nerve cells function, used to treat certain medical conditions.

These medicines may interact with quetiapine and you may experience symptoms such as involuntary rhythmic muscle contractions, including muscles controlling eye movement, agitation, hallucinations, coma, excessive sweating, tremor, exaggerated reflexes, increased muscle tone, and body temperature above 38°C (serotonin syndrome). Contact your doctor if you experience these symptoms.
