1. What is quetiapine cinfa and what is it used for

quetiapine cinfa 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: when you feel sad. You may feel depressed, guilty, lack energy, lose your appetite, or be unable to sleep.
• Mania: when you may feel overly excited, euphoric, restless, enthusiastic, or hyperactive, or have 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 even after you start feeling better.

2. What you need to know before taking quetiapine cinfa

Do not take quetiapine cinfa

• 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 cinfa.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take quetiapine cinfa:

• if you, or a family member, have or have had any heart problems, for example, heart rhythm disorders, weakening of the heart muscle, or heart inflammation, or if you are taking any medicine that may affect your heartbeat.
• 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 treated with antidepressants. Using these medicines together with quetiapine cinfa may cause serotonin syndrome, a potentially life-threatening condition (see “Other medicines and quetiapine cinfa”).
• 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 because the group of medicines to which quetiapine cinfa 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 fully 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 required.
• 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 (convulsions).
• A prolonged and painful erection (priapism).
• 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.

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 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 stop taking your medication abruptly. You may be more likely to have such thoughts if you are a young adult. Clinical trial data 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 adverse reactions (SCARs), which may 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 blistering and peeling of the skin, 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 cell count (eosinophilia) and elevated liver enzymes).

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

Weight gain

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

Children and adolescents

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

Other medicines and quetiapine cinfa

Inform your doctor if you are taking, have recently taken, or might need to take any other medicine.

Do not take quetiapine if you are using any of the following medicines:

• Some medicines for HIV.
• Azole-type medicines (for fungal infections).
• Erythromycin or clarithromycin (for infections).
• Nefazodona (for depression).

Inform your doctor if you are using any of the following medicines:

• Medicines for epilepsy (such as phenytoin or carbamazepine).
• Medicines for high blood pressure.
• Barbiturates (for difficulty sleeping).
• Thioridazine or lithium (other antipsychotic medicines).
• Antidepressants. These medicines may interact with quetiapine cinfa, and you may experience symptoms such as involuntary rhythmic muscle contractions, including those controlling eye movement, agitation, hallucinations, coma, excessive sweating, tremor, exaggerated reflexes, increased muscle tone, and body temperature above 38°C (serotonin syndrome). Contact your doctor if you experience these symptoms.
• Medicines that affect your heartbeat, for example, medicines that may cause an electrolyte imbalance (low levels of potassium or magnesium), such as diuretics (medicines to increase urination) or certain antibiotics (medicines to treat infections).
• Medicines that may cause constipation.
• Medicines (called “anticholinergics”) that affect how nerve cells function, used to treat certain medical conditions.

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

Taking quetiapine cinfa with food, drinks, and alcohol

Quetiapine may be taken with or without food.

• Be cautious about the amount of alcohol you consume. This is because the combined effect of quetiapine and alcohol may make you drowsy.
• Do not drink grapefruit juice while taking quetiapine. It may affect how the medicine works.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine. 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 a 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.

Driving and using machines

Quetiapine may cause symptoms such as drowsiness, dizziness, or vision disturbances, and may reduce reaction ability. These effects, as well as the illness itself, may impair your ability to drive or operate machinery. Therefore, do not drive, operate machinery, or engage in other activities requiring special attention until your doctor has assessed your response to this medicine.

Quetiapine cinfa contains lactose and sodium.

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

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; this is essentially “sodium-free”.

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 analytical methods are used, even though you may not be taking methadone or TCAs. If this occurs, a more specific test can be performed.

3. How to take quetiapine cinfa

Follow exactly the administration instructions for this medicine given by your doctor. If in doubt, consult your doctor or pharmacist again. Your doctor will determine your starting dose. The maintenance dose (daily dose) will depend on your condition and individual needs, but will usually be between 150 mg and 800 mg.

• You will take your tablets once daily at bedtime or twice daily, depending on your condition.
• Swallow your tablets whole with water.
