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

Quetiapine STADA contains a substance called quetiapine. It belongs to a group of medicines called antipsychotics. Quetiapine STADA can be used to treat several diseases, such as:

• Bipolar depression: where you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite or cannot sleep.
• Mania: where you may feel very excited, elated, agitated, enthusiastic or hyperactive or have poor judgment including being aggressive or violent.
• Schizophrenia: where you may hear or feel things that are not there, believe things that are not true or feel abnormally suspicious, anxious, confused, guilty, tense or depressed.

Your doctor may continue to prescribe Quetiapine STADA even when you are feeling better.

2. What you need to know before you take Quetiapine STADA

Do not take Quetiapine STADA:

• if you are allergic to quetiapine or any of the other ingredients of this medicine (listed in section 6).

• if you are taking any of the following medicines:

or some medicines for HIV

or azole-type medicines (for fungal infections)

or erythromycin or clarithromycin (for infections)

or nefazodone (for depression).

If you are in doubt, consult your doctor or pharmacist before taking Quetiapine STADA.

Warnings and precautions

Consult your doctor or pharmacist before starting Quetiapine STADA:

• if you, or someone in your family, have or have had heart problems, such as problems with the heart rhythm, weakening of the heart muscle or inflammation of the heart, or if you are taking any medicine that may affect your heart beat.
• 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 quetiapine.
• if you know you have had low white blood cell counts in the past (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, you should not take quetiapine because the group of medicines to which Quetiapine STADA belongs 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 have 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 where your breathing stops for short periods of time during normal nighttime sleep (called "sleep apnea") and are taking medicines that reduce normal brain activity ("depressants").
• if you have or have had a condition where you cannot empty your bladder completely (urinary retention), have an enlarged prostate, a blockage in your intestines, or increased pressure within your eye. These conditions may be caused by medicines (called "anti-cholinergics") that affect how nerve cells work to treat certain medical conditions.
• if you have a history of alcohol or drug abuse.
• if you suffer from 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 Quetiapine STADA").

Tell your doctor immediately if, after taking Quetiapine STADA, you experience any of the following:

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

These disorders can be caused by this type of medicine.

Tell 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 may require interruption of treatment with quetiapine and/or additional treatment.
• Constipation along with persistent abdominal pain, or constipation that has not responded to treatment, as it could lead to a more severe bowel obstruction.

Thoughts of suicide and worsening of your depression

If you are depressed, you may sometimes have thoughts of harming or killing yourself. These may be increased when you first start taking this treatment, since these medicines take time to start working, 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 suicidal thoughts and/or suicidal behavior in young adults under 25 years with depression.

If at any time you have thoughts of harming or killing yourself, contact your doctor or go to a hospital immediately. It may be helpful to tell a relative or close friend that you are depressed and ask them to read this leaflet. You can ask them to tell you if they think your depression has got worse, or if they are worried about changes in your behavior.

Weight gain

Weight gain has been seen in patients taking quetiapine. You and your doctor should check your weight regularly.

Children and adolescents

Quetiapine STADA should not be used in children and adolescents under 18 years of age.

Using Quetiapine STADA with other medicines

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

Do not take Quetiapine STADA if you are using any of the following medicines:

• Some medicines for HIV.
• Azole-type medicines (for fungal infections).
• Erythromycin or clarithromycin (for infections).
• Nefazodone (for depression).

Tell your doctor if you are using any of the following medicines:

• Medicines for epilepsy (such as phenytoin or carbamazepine).
• Medicines for high blood pressure.
• Barbiturates (for difficulty sleeping).

• Medicines that affect your heart beat, such as medicines that can cause an imbalance in electrolytes (low potassium or magnesium levels), such as diuretics (medicines to urinate) or certain antibiotics (medicines to treat infections).
• Medicines that can cause constipation.
• Medicines (called "anti-cholinergics") that affect how nerve cells work to treat certain medical conditions.
• Antidepressants. These medicines can interact with quetiapine, and you may experience symptoms such as involuntary muscle contractions and rhythmic movements of the muscles, including the muscles that control eye movement, agitation, hallucinations, coma, excessive sweating, tremors, increased muscle tension, and body temperature above 38°C (serotonin syndrome). Contact your doctor when you experience these symptoms.

If this happens, a more specific test can be performed.
