1. hat Seroquel is and what it is used for
Seroquel contains a medicine called quetiapine. This belongs to a group of medicines called anti-psychotics.
Seroquel can be used to treat several illnesses, such as:
• Schizophrenia: where you may hear or feel things that are not there, believe things that are not true or feel
unusually suspicious, anxious, confused, guilty, tense or depressed.
• Mania: where you may feel very excited, elated, agitated, enthusiastic or hyperactive or have poor judgment
including being aggressive or disruptive.
• Bipolar depression: where you may feel sad all the time or you may find that you feel depressed, feel guilty,
lack energy, lose your appetite or can’t sleep.
Your doctor may continue to prescribe Seroquel even when you are feeling better.
2. Before you take Seroquel
Do not take Seroquel if:
• you are allergic (hypersensitive) to quetiapine or any of the other ingredients of Seroquel (see Section 6:
Further information).
• you are taking any of the following medicines:
- protease inhibitors, such as nelfinavir (for HIV infection)
- azole medicines (for fungal infections)
- medicines for an infection (like erythromycin or clarithromycin)
- nefazodone (for depression).
Do not take Seroquel if the above applies to you. If you are not sure, talk to your doctor or pharmacist before
taking Seroquel.
Take special care with Seroquel
Before you take your medicine, tell your doctor if:
• You, or someone in your family, have or have had any heart problems such as a very fast heart beat or
prolonged QT on an ECG (heart tracing), 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 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 have diabetes or have a risk of getting diabetes. If you do, your doctor may check your blood sugar
levels while you are taking Seroquel.
• You are an elderly person with dementia. If you are, Seroquel should not be taken because the group of
medicines that Seroquel 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:
• A combination of 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 feeling very drowsy. 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
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 Seroquel. You and your doctor should check your weight
Taking other medicines
Please tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines because
it may affect the way the medicines work. This includes medicines that you buy without a prescription and

• High blood pressure medicines.
• Rifampicin (for tuberculosis).
• Barbiturates (for difficulty sleeping).
• Thioridazine (another anti-psychotic medicine).
• Medicines that affect the heart, for example, drugs that can cause an imbalance in some of the chemicals
in your blood such as diuretics (water pills) or certain antibiotics.
Before you stop taking any of your medicines, please talk to your doctor first.
If you have a urine drug screen, taking Seroquel could cause positive results for methadone or drugs for
depression called tricyclic antidepressants (TCAs), even though you may not be taking methadone or TCAs.
The result will need to be confirmed by a more specific test.
Taking Seroquel with food and drink
• Seroquel can be taken with or without food.
• Be careful how much alcohol you drink. This is because the combined effect of Seroquel and alcohol can
make you feel sleepy.
• Do not drink grapefruit juice while you are taking Seroquel. It can affect the way the medicine works.

The following symptoms may occur in newborn babies of mothers that have used Seroquel in the last

agitation, breathing problems and difficulty in feeding. If your baby develops any of these symptoms you may

3. How to take Seroquel
Always take Seroquel exactly as your doctor has told you. You should check with your doctor or pharmacist if
you are not sure. Your doctor will decide on your starting dose and may gradually increase it. When you are

illness and needs.
• You will take your tablets once a day, at bedtime or twice a day, depending on your illness.
• Swallow your tablets whole with a drink of water.

one 300 mg tablet (white) or two 150 mg tablets (pale yellow).
