1. What Quetiapina Qualigen Farma is and what it is used for

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

• Bipolar depression and major depressive episodes in major depressive disorder: in which you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite, or are unable to sleep.
• Mania: in which you may feel highly excited, euphoric, agitated, enthusiastic, or hyperactive, or have poor judgment, including aggressive or violent behavior.
• Schizophrenia: in which 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 Quetiapina Qualigen Farma extended-release tablets are used to treat major depressive episodes in major depressive disorder, they are taken in addition to another medicine you are already using for this condition.

Your doctor may continue prescribing Quetiapina Qualigen Farma even after you start feeling better.

2. What you need to know before taking Quetiapine Qualigen Farma

Do not take Quetiapine Qualigen Farma:

• If you are allergic (hypersensitive) to quetiapine or to any of the other components of Quetiapine Qualigen Farma (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 Farma if any of the above apply to you. If you have any doubts, consult your doctor or pharmacist before taking Quetiapine Qualigen Farma.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Quetiapine Qualigen Farma 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.

• 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 (epileptic fit).

• 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 you have previously had low levels of white blood cells (which may or may not have been caused by other medicines).

• You are an elderly person with dementia (loss of brain functions). If so, you should not take quetiapine, because the group of medicines to which Quetiapine Qualigen Farma belongs may increase the risk of stroke, or in some cases, the risk of death, in these individuals.

• You are an elderly person with Parkinson's disease/parkinsonism.

• You or a family member have a history of blood clots, as medicines like this have been associated with blood clot formation.

• You have or have had a disorder in which you stop breathing for short periods during normal nighttime sleep (called "sleep apnea") and you are taking medicines that slow down normal brain activity ("depressants").

• You have or have had a disorder in which you cannot completely empty your bladder (urinary retention), prostate enlargement, intestinal obstruction, or increased eye pressure. These disorders are sometimes caused by medicines (called "anticholinergics") that affect nerve cell function and are used to treat certain conditions.

• You have a history of alcoholism or drug abuse.

• 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 Quetiapine Qualigen Farma).

Inform your doctor immediately if, after taking Quetiapine Qualigen Farma, 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 excessive drowsiness. This may increase the risk of accidental injury (falls) in elderly patients.
• Seizures (epileptic fits).
• A prolonged and painful erection (priapism).
  • Rapid or irregular heartbeats, even at rest, palpitations, breathing difficulties, chest pain, or unexplained fatigue. 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 white blood cell count and may require discontinuation of quetiapine treatment and/or additional treatment.
• Constipation along 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 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 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 close family member or friend that you are depressed and ask them to read this leaflet. You may also ask them to inform you if they think your depression is worsening or if they are concerned 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 Farma must not be used in children and adolescents under 18 years of age.

• Medicines (called "anticholinergics") that affect nerve cell function and are used to treat certain conditions.
