1. What Quetiapine Teva-ratio is and what it is used for

Quetiapine Teva-ratio contains a substance called quetiapine. It belongs to a group of medicines known as antipsychotics. Quetiapine Teva-ratio can be used to treat several conditions, such as:

• Bipolar depression: when you feel sad. You may feel depressed, guilty, lack energy, lose your appetite, or have trouble sleeping.
• Mania: when you may feel overly excited, euphoric, agitated, enthusiastic, or hyperactive, or show poor judgment, including aggressive or violent behavior.
• Schizophrenia: when 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.

Your doctor may continue prescribing Quetiapine Teva-ratio even after you start feeling better.

2. What you need to know before taking Quetiapine Teva-ratio

Do not take Quetiapine Teva-ratio

• if you are allergic to quetiapine or to 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 have any doubts, consult your doctor or pharmacist before taking Quetiapine Teva-ratio.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Quetiapine Teva-ratio:

• 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 elderly.
• if you have liver problems.
• if you have ever had a seizure (epileptic fit).
• if 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 Teva-ratio”).
• 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). If so, you should not take quetiapine because the group of medicines to which Quetiapine Teva-ratio 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 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.

Inform 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 necessary.
• Rapid or irregular heartbeat, 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.
• Uncontrollable movements, mainly of your face or tongue.
• Dizziness or excessive drowsiness. This may increase the risk of accidental injuries (falls) in elderly patients.
• Seizures (epileptic fits).
• A prolonged and painful erection (priapism).

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 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 around 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 getting worse or if they are concerned about changes in your behavior.

Serious cutaneous adverse reactions (SCARs)

Very rarely, serious skin reactions (SCARs), which can be life-threatening or fatal, have been reported with the use of this medicine. These commonly manifest as:

• Stevens-Johnson syndrome (SJS), a widespread rash with blisters and skin peeling, particularly around the mouth, nose, eyes, and genitals.
• Toxic epidermal necrolysis (TEN), a more severe form causing extensive skin peeling.
• Drug reaction with eosinophilia and systemic symptoms (DRESS), characterized by flu-like symptoms with rash, fever, swollen lymph nodes, and abnormal blood test results (including increased white blood cells (eosinophilia) and elevated liver enzymes).
• Acute generalized exanthematous pustulosis (AGEP), small pustules filled with pus.
• Erythema multiforme (EM), skin rashes with irregular red spots that itch.

If you develop any of these symptoms, stop using quetiapine and contact your doctor or seek immediate medical attention.

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

Taking Quetiapine Teva-ratio with food, drinks, and alcohol

• Quetiapine Teva-ratio can be taken with or without food.

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 antidepressant medicines known as tricyclic antidepressants (TCAs), when certain testing methods are used, even if you are not taking methadone or TCAs. If this occurs, a more specific test can be performed.
