1. What Quetiapina Combix is and what it is used for

Quetiapina Combix contains a substance called quetiapine. It belongs to a group of medicines known as antipsychotics. Quetiapina Combix can be used to treat several conditions, such as:

• Schizophrenia: in 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: in which you may feel highly excited, euphoric, agitated, enthusiastic, or hyperactive, or have poor judgment, including aggressive behavior or destructive and aggressive conduct.
• Bipolar depression: in 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 to prescribe Quetiapina Combix even when you are feeling better.

2. What you need to know before taking Quetiapina Combix

Do not take Quetiapina Combix:

• if you are allergic to quetiapine or any of the other ingredients of this medicine (listed in section 6).

• if you are taking any of the following medicines:

• certain HIV medicines

• 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 Quetiapina Combix.

Warnings and precautions

Talk to your doctor or pharmacist before starting Quetiapina Combix:

• if you, or a family member, have or have had any heart problems, for example, heart rhythm problems, weakening of the heart muscle, or inflammation of the heart, or if you are taking medicines that may affect your heart rhythm.
• 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. If so, your doctor may monitor your blood sugar levels while you are taking Quetiapina Combix.
• 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 function). In this case, you should not take Quetiapina Combix, as the group of medicines it belongs to may increase the risk of stroke, or in some cases the risk of death, in elderly patients with dementia.
• 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 may 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.
• if you suffer from depression or other conditions treated with antidepressants.

Using these medicines together with Quetiapina Combix may cause serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Quetiapina Combix”).

Inform your doctor immediately if, after taking Quetiapina Combix, 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 necessary.

• Uncontrollable 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 (convulsions).

• Prolonged and painful erection (priapism).

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 white blood cell count and may require discontinuation of Quetiapina Combix 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 have thoughts of harming yourself or committing suicide. These thoughts 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 suddenly stop taking your medication. 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 have thoughts of 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 also ask them to inform you if they think your depression is worsening or if they are concerned about changes in your behavior.

Serious skin adverse reactions (SCARs)

Very rarely, serious skin adverse reactions (SCARs), which may be life-threatening or fatal, have been reported with 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 cells (eosinophilia) and elevated liver enzymes).
• Acute generalized exanthematous pustulosis (AGEP), small pustules filled with pus.
• Erythema multiforme (EM), skin eruptions with irregular red spots that itch.

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