1. What Quetiapina TecniGen is and what it is used for

Quetiapina TecniGen contains a substance called quetiapine. It belongs to a group of medicines known as antipsychotics. Quetiapine 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 being aggressive or violent.
• 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 quetiapine is used to treat major depressive episodes in major depressive disorder, it is taken in addition to another medicine you are already using for this condition.

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

2. What you need to know before taking Quetiapine TecniGen

Do not take Quetiapine TecniGen

• 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:
  • certain HIV medicines
  • 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 quetiapine.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Quetiapine TecniGen:

• You suffer from depression or other conditions treated with antidepressants. The use of these medicines together with Quetiapine TecniGen may cause serotonin syndrome, a potentially life-threatening condition (see "Use of Quetiapine TecniGen with other medicines").
• If you, or a family member, have or have had any heart problems, for example, irregular heartbeat, weakened heart muscle, or inflammation of the heart, 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 an elderly patient.
• 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 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, as 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 like 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.

Contact 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 required.
• Uncontrollable 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).
• 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 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 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 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 ask them to inform you if they think your depression is worsening or if they are concerned about changes in your behavior.

Serious skin reactions

Very rarely, serious and potentially life-threatening skin reactions have been reported with this medicine. These commonly manifest as:

• Stevens-Johnson syndrome, a widespread rash with blistering and peeling of the skin, especially around the mouth, nose, eyes, and genitals.
• Toxic Epidermal Necrolysis, a more severe form causing extensive skin peeling.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), characterized by flu-like symptoms, rash, fever, swollen lymph nodes, and abnormal blood test results (including increased white blood cells (eosinophilia) and liver enzymes).

Stop using quetiapine if you develop these symptoms and contact your doctor or seek immediate medical attention.

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

Children and adolescents

Contact your doctor if you experience these symptoms.
• Medicines for epilepsy (such as phenytoin or carbamazepine).
• Medicines for high blood pressure.
• Barbiturates (for difficulty sleeping).

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

Taking Quetiapine TecniGen with food, drinks, and alcohol

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

You should not take quetiapine during pregnancy unless advised by your doctor. You should not use quetiapine if you are breastfeeding.

The following symptoms, which may represent withdrawal syndrome, may occur in newborns of mothers who have used quetiapine during the third trimester (last three months of pregnancy): tremor, muscle rigidity and/or weakness, drowsiness, agitation, breathing difficulties, and feeding problems. If your newborn develops any of these symptoms, you may need to contact your doctor.

If your doctor has informed you that you have an intolerance to certain sugars, consult with him before taking this medicine.

Effect on Urine Drug Screening Tests

If you are undergoing a urine drug screening test, taking quetiapine may produce positive results for methadone or certain antidepressants known as tricyclic antidepressants (TCAs) when certain testing methods are used, even though you may not be taking methadone or TCAs. If this occurs, a more specific test can be performed.
