1. What Quetiapine Laboratori Alter is and what it is used for
Quetiapine Laboratori Alter contains a substance called quetiapine. This substance
belongs to a group of medicines known as antipsychotics. Quetiapine Laboratori Alter can
be used to treat several conditions, such as the following:
- Bipolar depression and major depressive episodes associated with major depressive disorder: you may feel sad. You may notice that you feel depressed, guilty, lack energy, have reduced appetite, or have difficulty sleeping.
- Mania: you may feel highly excited, euphoric, restless, enthusiastic, or hyperactive, or have poor judgment, including aggressive or destructive behaviour.
- Schizophrenia: you may experience hearing or sensing things that are not actually present, believe things that are not true, or feel unusually suspicious, anxious, confused, guilty, tense, or depressed.
When Quetiapine Laboratori Alter is used to treat major depressive episodes
in major depressive disorder, it will be taken in addition to another medicine
used to treat this condition.
Your doctor may continue to prescribe Quetiapine Laboratori Alter even after you start
feeling better.
2. What you need to know before taking Quetiapine Laboratori Alter
Do not take Quetiapine Laboratori Alter:
- 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:
- certain medicines for HIV virus
- azole medicines (for fungal infections)
- erythromycin or clarithromycin (for infections)
- nefazodone (for depression).
If you have any doubts, ask your doctor or pharmacist before taking this medicine.
Warnings and precautions
Talk to your doctor or pharmacist before taking quetiapine:
- You or someone in your family has or has previously had heart problems, such as irregular heart rhythm, weakened heart muscle, or inflammation of the heart, or if you are taking medicines that may affect your heartbeat.
- If your blood pressure is low.
- If you have had a stroke, especially if you are elderly.
- If you have liver problems.
- If you have had seizures (epileptic fits).
- If you have diabetes or are at risk of developing diabetes. In this case, your doctor may monitor your blood sugar levels while you are taking this medicine.
- If you know you have previously had low levels of white blood cells in your blood (whether caused by medicines or not).
- If you are an elderly person with dementia (loss of certain brain functions). In this case, you should not take quetiapine, because this class of medicines, to which quetiapine belongs, may increase the risk of stroke, or in some cases, the risk of death.
- if you are an elderly person with Parkinson’s disease/parkinsonism.
- If you or someone in your family has a history of conditions related to blood clots, as medicines of this type may promote blood clot formation.
- If you have or have previously had a condition (called "sleep apnea") in which you stop breathing for short periods during normal nighttime sleep and you are taking medicines that slow down normal brain activity ("depressants").
- If you have or have previously had a condition in which you are unable to completely empty your bladder (urinary retention), have an enlarged prostate, intestinal obstruction, or increased pressure inside the eye. These conditions are sometimes caused by medicines (called "anticholinergics") that affect how nerve cells function and are used to treat certain medical conditions.
- If you have a history of alcohol or drug abuse.
Inform your doctor immediately if you experience any of the following effects after taking quetiapine:
- A combination of fever, severe muscle stiffness, sweating, or reduced level of consciousness (a condition called "neuroleptic malignant syndrome"). Immediate medical treatment may be required.
- Uncontrolled movements, mainly of the face or tongue.
- Dizziness or feeling very sleepy. This may increase the risk of accidental injuries (falls) in elderly patients.
- Seizures (fits).
- A prolonged and painful erection (priapism).
- Fast or irregular heartbeat, even at rest, palpitations, breathing problems, chest pain, or unexplained tiredness. 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 these could be signs of a very low white blood cell count, which may require that quetiapine be stopped and/or additional treatment be administered;
- Constipation together 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 depression
- If you are depressed, you may sometimes feel the need to harm yourself or to kill yourself. These feelings may be stronger at the beginning of treatment, as these medicines take time to work, usually about two weeks but sometimes longer. These thoughts may also intensify if you suddenly stop taking the medicine. You are more likely to have these types of feelings if you are a young adult. Data from clinical trials have indeed shown an increased risk of suicidal thoughts and/or suicidal behaviour in young adults with depression under the age of 25.
- If at any time you notice that you are having thoughts of self-harm or suicide, contact your doctor or go immediately to the hospital. You may find it helpful to inform a relative or close friend that you suffer from depression and ask them to read this leaflet. You may ask them to alert you if they think your depression is worsening or if they are concerned about any changes in your behaviour.
Weight gain
Weight gain has been reported in patients treated with quetiapine. It is necessary that your body weight be monitored regularly by both you and your doctor.
Children and adolescents
Quetiapine must not be used in children and adolescents under 18 years of age.
Other medicines and Quetiapine Laboratori Alter

- Medicines for epilepsy (such as phenytoin or carbamazepine).
- Medicines for high blood pressure.
- Barbiturates (for sleep disorders).
- Thioridazine or Lithium (other antipsychotic medicines).
- Medicines that affect heart rhythm, for example medicines that can 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 can cause constipation.
- Medicines (called "anticholinergics") that affect how nerve cells function and are used to treat certain medical conditions. Consult your doctor before stopping treatment with any of these medicines.
Quetiapine Laboratori Alter with food, drinks and alcohol
- Quetiapine may be affected by food; therefore, you should take the tablets at least one hour before a meal or before going to bed.
- Be cautious about the amount of alcohol you consume. This is important because the combined effect of quetiapine and alcohol may increase the likelihood of drowsiness.

Pregnancy and breastfeeding

The following symptoms, which may represent withdrawal, have been observed in newborns whose mothers took quetiapine during the third trimester (the last three months of pregnancy):
tremor, muscle stiffness and/or weakness, drowsiness, agitation, breathing problems, and difficulty feeding. If your baby shows any of these symptoms, contact your doctor.
Driving and using machines
The tablets may cause drowsiness. Do not drive or operate any tools or machinery until you know how the tablets affect you.
Quetiapine Laboratori Alter contains lactose
Quetiapine Laboratori Alter contains lactose, a type of sugar. If your doctor has diagnosed you with an intolerance to certain sugars, contact him before taking this medicine.
Effect on urine screening tests
If you need to undergo a urine screening test, taking Quetiapine Laboratori Alter may lead to false positive results for methadone or certain antidepressant medicines called tricyclic antidepressants (TCA), when certain testing methods are used, even if you are not taking methadone or TCAs. If this occurs, more specific tests should be performed.
