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

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

  • Bipolar depression and major depressive episodes in major depressive disorder: for which you feel sad. You may find that you feel depressed, feel guilty, lack energy, lose your appetite, or cannot sleep.
  • Mania: for which you may feel very excited, euphoric, agitated, enthusiastic, or hyperactive, or show poor judgment, including being aggressive or violent.
  • Schizophrenia: for which 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 is used to treat major depressive episodes in major depressive disorder, it will be taken in addition to another medication used to treat this disease.

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

2. What you need to know before you take 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:
  • some medicines for HIV
  • azole-type medicines (for fungal infections)
  • erythromycin or clarithromycin (for infections)
  • nefazodone (for depression).

If you are in doubt, 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 that are treated with antidepressants. The use of these medications along with Quetiapine TecniGen may cause serotonin syndrome, a potentially life-threatening condition (see "Use of Quetiapine TecniGen with other medications").
  • 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 rate.
  • 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 had low white blood cell counts in the past (which may or may not have been caused by other medications).
  • If you are an elderly person with dementia (loss of brain function). If so, you should not take quetiapine because the group of medications 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 have a history of blood clots, as medications like this have been associated with the formation of blood clots.
  • If you have or have had a condition in which your breathing is interrupted for short periods during normal nighttime sleep (called "sleep apnea") and are taking medications that decrease 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, an obstruction in your intestine, or high pressure inside your eye. These conditions may be caused by medications (called "anticholinergics") that affect how nerve cells work, to treat certain medical conditions.
  • If you have a history of alcohol or drug abuse.

Tell your doctor immediately if after taking quetiapine 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"). 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 injuries (falls) in elderly patients.
  • Seizures (convulsions).
  • A prolonged and painful erection (priapism).
  • Fast and irregular heartbeats, even when 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 medication.

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 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 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 start treatment, as all these medications 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 obtained in 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 close family member or 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.

Severe skin reactions

Very rare but potentially life-threatening skin reactions have been reported with this medication. These are commonly manifested by:

  • Stevens-Johnson syndrome, a widespread rash with blisters and peeling of the skin, especially around the mouth, nose, eyes, and genitals.
  • Toxic Epidermal Necrolysis, a more severe form that causes widespread peeling of the skin.
  • Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), which consists of flu-like symptoms, rash, fever, lymph node inflammation, and abnormal blood test results (including elevated white blood cell count (eosinophilia) and liver enzymes).

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