- Schizophrenia: where 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.
Your doctor may continue to prescribe Quetiapine Teva-ratio even when you are feeling better.

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, 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 elderly.
- if you have liver problems.
- if you have ever had a seizure (convulsion).
- if you suffer from depression or other conditions that are treated with antidepressants. The use of these medications with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications 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 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 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 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 stops 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 empty your bladder completely (urinary retention), have an enlarged prostate, a bowel obstruction, or increased 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, and decreased level of consciousness (a disorder called "neuroleptic malignant syndrome"). Immediate medical treatment may be necessary.
- 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.
- 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).
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 may 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 bowel obstruction.
- 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 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 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 be helpful to tell a family member or close friend that you are depressed and ask them to read this package leaflet. You can ask them to tell you if they think your depression is getting worse, or if they are concerned about changes in your behavior.
Severe Skin Reactions (SCARs)
With the use of this medication, very rare but severe skin reactions (SCARs) have been reported, which can be life-threatening or fatal. These are commonly manifested as:
- Stevens-Johnson syndrome (SSJ), a widespread rash with blisters and peeling of the skin, particularly around the mouth, nose, eyes, and genitals.
- Toxic epidermal necrolysis (TEN), a more severe form that causes extensive peeling of the skin.
- Drug reaction with eosinophilia and systemic symptoms (DRESS), which consists of flu-like symptoms with a rash, fever, swollen lymph nodes, and abnormal blood test results (including an increased number of white blood cells (eosinophilia) and elevated liver enzymes).
- Acute generalized exanthematous pustulosis (AGEP), small pus-filled blisters.
- Erythema multiforme (EM), skin rashes with irregular red patches that itch.
If you develop these symptoms, stop using quetiapine and contact your doctor or seek medical attention immediately.
