Warnings and precautions
Consult your doctor or pharmacist before starting Quetiapine Kern Pharma if:
- You, or a family member, have or have had heart problems, such as problems with your heart rhythm, weakening of the heart muscle or inflammation of the heart, or if you are taking any medicine that may affect your heart beat.
- You have low blood pressure.
- You have had a stroke, especially if you are an elderly patient.
- You have liver problems.
- You have ever had a seizure (convulsion).
- 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.
- You know you have had low white blood cell counts in the past (which may or may not have been caused by other medicines). You are an elderly patient with dementia (loss of brain function). If so, you should not take quetiapine because the group of medicines to which Quetiapine Kern Pharma belongs may increase the risk of stroke, or in some cases the risk of death, in these patients.
- You, or a family member, have a history of blood clots, as medicines like these have been associated with the formation of blood clots.
- You have depression or other conditions that are treated with antidepressants. The use of these medicines with quetiapine may cause serotonin syndrome, a potentially life-threatening condition (see "Using Quetiapine Kern Pharma with other medicines").
Tell your doctor immediately if, after taking Quetiapine Kern Pharma, you experience any of the following:
- A combination of fever, severe muscle stiffness, sweating or a decrease in consciousness level (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 injury (falls) in elderly patients.
- Seizures (convulsions).
- A prolonged and painful erection (priapism).
- Rapid and irregular heartbeats, even when at rest, palpitations, breathing difficulties, 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 medicine.
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 bowel obstruction.
Thoughts of suicide and worsening of your depression
If you are depressed, you may sometimes think of harming or killing yourself. This may increase at the beginning of treatment, as all these medicines 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 of harming or killing yourself, contact your doctor or go to a hospital immediately. It may help to tell a relative or close 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 worried about changes in your behavior.
