Take special care with Quetiapine Teva
Before you take your medicine, tell your doctor if:
- You, or someone in your family, have or have had any heart problems, for example heart rhythm problems or if you are taking any medicines that may have an impact on the way your heart beats.
- You have low blood pressure.
- You have had a stroke, especially if you are elderly.
- You have problems with your liver.
- You have ever had a fit (seizure).
- You have diabetes or have a risk of getting diabetes. If you do, your doctor may check your blood sugar levels while you are taking Quetiapine Teva.
- You know that you have had low levels of white blood cells in the past (which may or may not have been caused by other medicines).
- You are an elderly person with dementia (loss of brain function). If you are, Quetiapine Teva should not be taken because the group of medicines that Quetiapine Teva belongs to may increase the risk of stroke, or in some cases the risk of death, in elderly people with dementia.
- You or someone else in your family has a history of blood clots, as medicines like these have been associated with formation of blood clots.
Tell your doctor immediately if you experience:
- Fever, severe muscle stiffness, sweating or a lowered level of consciousness (a disorder called “neuroleptic malignant syndrome”). Immediate medical treatment may be needed.
- Uncontrollable movements, mainly of your face or tongue.
- Dizziness or a severe sense of feeling sleepy. This could increase the risk of accidental injury (fall) in elderly patients.
- Fits (seizures).
- A long-lasting and painful erection (Priapism).
These conditions can be caused by this type of medicine.
Thoughts of suicide and worsening of your depression
If you are depressed you may sometimes have thoughts of harming or killing yourself. These may be increased when first starting treatment, since these medicines all take time to work, usually about two weeks but sometimes longer. These thoughts may also be increased if you suddenly stop taking your medication.
You may be more likely to think like this if you are a young adult. Information from clinical trials has shown an increased risk of suicidal thoughts and/or suicidal behaviour in young adults aged less than 25 years with depression.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away. You may find it helpful to tell a relative or close friend that you are depressed, and ask them to read this leaflet. You might ask them to tell you if they think your depression is getting worse, or if they are worried about changes in your behaviour.
Weight gain has been seen in patients taking quetiapine. You and your doctor should check your weight regularly.
Taking other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription and herbal medicines.
Do not take Quetiapine Teva if you are taking any of the following medicines:
- Some medicines for HIV.
- Azole medicines (for fungal infections).
- Erythromycin or clarithromycin (for infections).
- Nefazodone (for depression).
Tell your doctor if you are taking any of the following medicines:
- Epilepsy medicines (like phenytoin or carbamazepine).
- High blood pressure medicines.
- Barbiturates (for difficulty sleeping).
- Thioridazine (another anti-psychotic medicine).
- Medicines that have an impact on the way your heart beats, for example, drugs that can cause an imbalance in electrolytes (low levels of potassium or magnesium) such as diuretics
(water pills) or certain antibiotics (drugs to treat infections).
Before you stop taking any of your medicines, please talk to your doctor first.
Taking Quetiapine Teva with food and drink
- Quetiapine Teva can be affected by food and you should therefore take your tablets at least one hour before a meal or prior to bedtime.
- Be careful how much alcohol you drink. This is because the combined effect of Quetiapine Teva and alcohol can make you sleepy.
- Do not drink grapefruit juice while you are on Quetiapine Teva treatment. It can affect the way the medicine works.
Pregnancy and breast-feeding
If you are pregnant, trying to get pregnant, or breast-feeding, talk to your doctor before taking Quetiapine Teva. You should not take Quetiapine Teva during pregnancy unless this has been discussed with your doctor. Quetiapine Teva should not be taken if you are breast-feeding.
The following symptoms may occur in newborn babies, of mothers that have used quetiapine in the last trimester (last three months of their pregnancy): shaking, muscle stiffness and/or weakness, sleepiness, agitation, breathing problems, and difficulty in feeding. If your baby develops any of these symptoms you may need to contact your doctor.
Driving and using machines
Your tablets may make you feel sleepy. Do not drive or use any tools or machines until you know how the tablets affect you.
Effect on Urine Drug Screens
If you are taking quetiapine and have a urine drug screen, some test methods may cause positive results for methadone or TCAs (drugs for depression called tricyclic antidepressants), even though you may not be taking methadone or TCAs. If this happens, a more specific test can be performed.
