1. What Quetiapine Pensa is and what it is used for
This medication contains a substance called quetiapine. It belongs to a group of medications called antipsychotics. This medication can be used to treat several diseases, such as:
- Bipolar depression and major depressive episodes in major depressive disorder: for which you feel sad. You may find that you feel depressed, guilty, lack energy, lose appetite, or have difficulty sleeping.
- Mania: for which you may feel very excited, euphoric, agitated, enthusiastic, or hyperactive, or show poor judgment, including being aggressive or violent.
- 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.
When this medication is used to treat major depressive episodes in major depressive disorder, it will be taken in addition to another medication used to treat this disease.
Your doctor may continue to prescribe this medication even when you are feeling better.
2. What you need to know before taking Quetiapine Pensa
Do not take Quetiapine Pensa:
- 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 this medication.
Warnings and precautions
Consult your doctor or pharmacist before starting to take quetiapine:
- 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 have diabetes or are at risk of developing diabetes. If so, your doctor may monitor your blood sugar levels while you are taking this medication.
- 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 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 one have been associated with the formation of blood clots.
- if you have or have had a condition in which your breathing stops for short periods 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 empty your bladder completely (urinary retention), have an enlarged prostate, a bowel obstruction, or increased pressure inside your eye. These conditions may be caused by medications (called "anticholinergics") that affect how nerve cells work, used to treat certain medical conditions.
- if you have a history of alcohol or drug abuse.
- If you have depression or other conditions treated with antidepressants. The use of these medications with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see "Other medications and Quetiapine Pensa").
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).
- Fast 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 severe bowel obstruction.
- Thoughts of suicide 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 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 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 close family member or friend that you are depressed and ask them to read this 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.
- Drug rash with eosinophilia and systemic symptoms (DRESS). Widespread rash, elevated body temperature, elevated liver enzymes, blood abnormalities (eosinophilia), enlarged lymph nodes, and other organs involved (drug rash with eosinophilia and systemic symptoms, also known as DRESS).
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 Pensa
Tell your doctor if you are taking, have recently taken, or may need to take any other medication.
Do not take this medication if you are using any of the following medications:
- Some HIV medications.
- Azole-type medications (for fungal infections).
- Erythromycin or clarithromycin (for infections).

- Medications that can cause constipation.
- Medications (called "anticholinergics") that affect how nerve cells work, used to treat certain medical conditions.

These medications can interact with quetiapine, 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 tension, and body temperature above 38°C (serotonin syndrome). Contact your doctor if you experience these symptoms.
