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

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

• Bipolar depression and major depressive episodes in major depressive disorder: when you feel sad. You may find that you feel depressed, feel guilty, lack energy, lose your appetite, or have trouble sleeping.
• Mania: when you may feel very excited, euphoric, agitated, enthusiastic, or hyperactive, or show poor judgment, including being aggressive or violent.
• Schizophrenia: when 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.

When Quetiapine Qualigen prolonged-release tablets are used to treat major depressive episodes in major depressive disorder, they will be taken in addition to another medication that is being used to treat this condition.

Your doctor may continue to prescribe Quetiapine Qualigen even when you feel better.

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

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

Do not take Quetiapine Qualigen if any of the above applies to you. If you are unsure, consult your doctor or pharmacist before taking Quetiapine Qualigen.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Quetiapine Qualigen if:

• You, or a family member, have or have had any heart problems, such as heart rhythm problems, heart muscle weakness, or heart inflammation, or if you are taking any medication that may affect your heart rhythm.
• You have low blood pressure.
• You have had a stroke, especially if you are elderly.
• You have liver problems.
• You have ever had a seizure (convulsion).
• 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.
• You know that you have had low white blood cell counts in the past (which may or may not have been caused by other medications).
• You are an elderly person with dementia (loss of brain function). If so, you should not take quetiapine, because the group of medicines that Quetiapine Qualigen belongs to may increase the risk of stroke, or in some cases the risk of death, in these people.
• You or a family member have a history of blood clots, as medicines like this one 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 Quetiapine Qualigen may cause serotonin syndrome, a potentially life-threatening condition (see "Other medicines and Quetiapine Qualigen").

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

• A combination of fever, severe muscle stiffness, sweating, or a decrease in the level of consciousness (a disorder called "neuroleptic malignant syndrome"). You may need immediate medical treatment.
• Uncontrolled movements, mainly of your face or tongue.
• Dizziness or feeling very drowsy. This can increase the risk of accidental injuries (falls) in elderly patients.
• Seizures (convulsions).
• A prolonged and painful erection (priapism).
• Fast and irregular heartbeats, even when you are at rest, palpitations, breathing problems, 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 discontinuation 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 intestinal blockage.

Thoughts of suicide and worsening of your depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This can increase when you first start treatment, as all these medicines take time to work, usually around two weeks but sometimes longer. These thoughts can 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 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 family member 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 is getting worse, or if they are worried about changes in your behavior.

Weight gain

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

Children and adolescents

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

Other medicines and Quetiapine Qualigen

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

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

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

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 rhythm, 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.
• Antidepressants. These medicines can interact with Quetiapine Qualigen, 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 if you experience these symptoms.

Before stopping any of your medicines, consult your doctor first.

Taking Quetiapine Qualigen with food, drinks, and alcohol

• Quetiapine Qualigen may be affected by food, and therefore you should take your tablets at least one hour before a meal or before bedtime.

Pregnancy and breastfeeding

If your newborn develops any of these symptoms, you may need to contact your doctor.

Driving and using machines

Quetiapine may cause symptoms such as drowsiness, dizziness, or changes in vision, and may reduce your reaction time. These effects, as well as your own illness, may impair your ability to drive vehicles or operate machinery. Therefore, do not drive, operate machinery, or engage in other activities that require special attention until your doctor assesses your response to this medicine.

Effect on drug tests in urine

If you are undergoing a urine test for drugs, taking quetiapine may produce positive results for methadone or certain antidepressants called tricyclic antidepressants (TCAs) when some analysis methods are used, even if you are not taking methadone or TCAs. If this happens, a more specific test can be performed.
