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

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

• Bipolar depression: where you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite, or have difficulty sleeping.
• Mania: where you may feel very excited, euphoric, agitated, enthusiastic, or hyperactive, or show poor judgment, including being aggressive or violent.
• 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 to you even when you are feeling better.

2. What you need to know before taking quetiapine cinfa

Do not take quetiapine cinfa

• If you are allergic to quetiapine or any of the other components of this medication (listed in section 6).
• If you are taking any of the following medications:
• • some HIV medications
  • azole-type medications (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

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

• 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 cinfa may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications 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 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 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 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 you 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 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 may increase the risk of accidental injuries (falls) in elderly patients.
• Seizures (convulsions).
• A prolonged and painful erection (priapism).
• Rapid 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 may 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 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 when you first start treatment, as all these medications 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 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 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).

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

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 medications and quetiapine cinfa

Tell your doctor if you are taking, have recently taken, or may need to take any other medication.

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

• Some HIV medications.
• Azole-type medications (for fungal infections).

Tell your doctor if you are using any of the following medications:

• Medications for epilepsy (such as phenytoin or carbamazepine).
• Medications for high blood pressure.
• Barbiturates (for difficulty sleeping).
• Thioridazine or lithium (other antipsychotic medications).
• Antidepressants. These medications may interact with quetiapine cinfa, and you may experience symptoms such as involuntary muscle contractions and rhythmic movements of the muscles, including the muscles that control eye movement, agitation, hallucinations, coma, excessive sweating, tremors, increased muscle tone, and body temperature above 38°C (serotonin syndrome). Contact your doctor if you experience these symptoms.
• Medications that affect your heart rate, such as medications that can cause an imbalance in electrolytes (low potassium or magnesium levels), such as diuretics (medications to urinate) or certain antibiotics (medications to treat infections).
• Medications that can cause constipation.
• Medications (called "anticholinergics") that affect how nerve cells work, to treat certain medical conditions.

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

Taking quetiapine cinfa with food, drinks, and alcohol

Quetiapine can be taken with or without food.

• Be careful with the amount of alcohol you drink. 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 medication 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 medication. You should not take quetiapine during pregnancy, unless you have discussed it with your doctor. You should not use quetiapine if you are breastfeeding.

The following symptoms, which may represent a withdrawal syndrome, may appear in newborns of mothers who have used quetiapine in the last trimester (last three months of pregnancy): tremors, muscle stiffness and/or weakness, drowsiness, agitation, breathing problems, and difficulty feeding. 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 changes in vision, and may decrease your reaction ability. These effects, as well as the underlying disease, may impair your ability to drive vehicles or operate machines. Therefore, do not drive, operate machines, or engage in other activities that require special attention until your doctor assesses your response to this medication.

quetiapine cinfa contains lactose and sodium.

This medication contains lactose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.

Effect on urine drug detection tests

If you are undergoing a urine drug detection test, taking quetiapine may produce positive results for methadone or certain antidepressant medications called tricyclic antidepressants (TCAs) when using some analysis methods, even if you are not taking methadone or TCAs. If this occurs, a more specific test can be performed.
