quetiapina cinfa contains a substance called quetiapina. It belongs to a group of medicines called antipsicotics. Quetiapina can be used to treat several diseases, such as:

• Bipolar depression: when you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite or cannot sleep.
• Mania: when you may feel very excited, euphoric, agitated, enthusiastic or hyperactive or present poor judgment which includes being aggressive or violent.
• Schizophrenia: when 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 prescribing quetiapina even when you are feeling better.

Do not take quetiapina cinfa

If you have any doubts, consult your doctor or pharmacist before taking quetiapina cinfa.

Warnings and precautions

Consult your doctor or pharmacist before starting to take quetiapina cinfa:

• If you, or a family member, have or have had any heart problems, for example, irregular heart rhythm, 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 have depression or other conditions treated with antidepressants. The use of these medications with quetiapina cinfa may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications and quetiapina cinfa").
• If you have diabetes or are at risk of developing diabetes. Your doctor may monitor your blood sugar levels while you are taking quetiapina.
• If you know you have had low white blood cell counts (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, do not take quetiapina because the group of medications to which quetiapina belongs may increase the risk of stroke or, in some cases, death in these individuals.
• If you are an elderly person with Parkinson's disease or parkinsonism.
• If you or a family member has a history of blood clots, as medications like these have been associated with blood clot formation.
• If you have or have had a condition in which your breathing is interrupted by brief periods of time 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, intestinal obstruction, or high pressure inside your eye. These conditions may be caused by medications (called "anticholinergics") that affect how nerve cells function, to treat certain medical conditions.
• If you have a history of alcohol or drug abuse.

Inform your doctor immediately if after taking quetiapina you experience any of the following:

• A combination of fever, intense muscle stiffness, sweating, or a decrease in consciousness (a condition called "neuroleptic malignant syndrome"). You may need immediate medical treatment.
• Uncontrolled 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).
• Prolonged and painful erection (priapism).
• Rapid and irregular heartbeats, even when at rest, palpitations, respiratory problems, chest pain, or unexplained fatigue. Your doctor should examine your heart and, if necessary, refer you to a cardiologist immediately.

These conditions may be caused by this type of medication.

Inform your doctor as soon as possible if you have:

• Fever, symptoms similar to the flu, sore throat, or any other infection, as it could be a consequence of very low white blood cell counts and require discontinuation of quetiapina treatment and/or additional treatment.
• Constipation with persistent abdominal pain, or constipation that has not responded to treatment, as it may lead to more severe intestinal blockage.

Thoughts of suicide and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This may increase at the beginning of treatment, as all these medications take time to be effective, usually around two weeks but sometimes longer. These thoughts may 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 behavior in young adults under 25 years old with depression.

If you ever think about harming yourself or committing suicide, contact your doctor or go to the 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 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 severe skin reactions (SCARs) have been reported, which may put your life at risk or be fatal. These typically manifest as:

• Stevens-Johnson syndrome (SSJ), a generalized rash with blisters and skin peeling, particularly around the mouth, nose, eyes, and genitals.
• Toxic epidermal necrolysis (NET), a more severe form that causes extensive skin peeling.
• Drug reaction with eosinophilia and systemic symptoms (DRESS), which consists of flu-like symptoms, rash, fever, swollen lymph nodes, and abnormal blood test results (including increased white blood cell count and elevated liver enzymes).

If you develop these symptoms, stop using quetiapina and contact your doctor or seek medical attention immediately.

Weight gain

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

Children and adolescents

Quetiapina should not be used in children and adolescents under 18 years of age.

Contact your doctor when you experience these symptoms.

If your newborn develops any of these symptoms, you may need to contact your doctor.

Driving and operating machinery
