Quetiapina Combix contains a substance called quetiapine. It belongs to a group of medications called antipsychotics. Quetiapina Combix may be used to treat various conditions, including:

• Schizophrenia: for which 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.
• Mania: for which you may feel extremely excited, euphoric, agitated, enthusiastic, or hyperactive, or exhibit poor judgment, including aggressive or destructive behaviors.
• Bipolar depression: for which you feel sad. You may find that you feel depressed, guilty, lack energy, lose your appetite, or are unable to sleep.

Your doctor may continue prescribing Quetiapina Combix even when you are feeling better.

Do not take Quetiapina Combix:

• if you are allergic to quetiapine or any of the other ingredients 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 Quetiapina Combix.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Quetiapina Combix:

• 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 medications 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 diabetes or are at risk of developing diabetes. Your doctor may monitor your blood sugar levels while you are taking Quetiapina Combix.
• if you know that 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 Combix because the group of medications to which it belongs may increase the risk of stroke or, in some cases, death in elderly people with dementia.
• 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 this 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 work to treat certain medical conditions.
• if you have a history of alcohol or drug abuse.
• if you have depression or other conditions that are treated with antidepressants.

The use of these medications with Quetiapina Combix may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications and Quetiapina Combix").

Inform your doctor immediately if after taking Quetiapina Combix 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.
• Seizure (convulsion).
• Prolonged and painful erection (priapism).

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 may be a consequence of a very low white blood cell count and require discontinuation of Quetiapina Combix treatment and/or additional treatment.
• Constipation along with persistent abdominal pain, or constipation that has not responded to treatment, as it may lead to a 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 work, 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 thoughts of suicide and/or suicidal behavior in young adults under 25 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 cutaneous adverse reactions (SCARs)

Very rarely, with the use of this medication, severe cutaneous adverse 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 (TEN), a more severe form that causes extensive skin peeling.
• Drug reaction with eosinophilia and systemic symptoms (DRESS), which consists of flu-like symptoms with rash, fever, swollen lymph nodes, and abnormal blood test results (including increased white blood cell count and elevated liver enzymes).
• Generalized acute pustular psoriasis (AGEP), small pus-filled blisters.
• Multiforme erythema (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.
