Seroquel XL contains a medicine called quetiapine. This belongs to a

treat several illnesses, such as:

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
 Bipolar depression and major depressive episodes in major depressive
disorder: 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
When Seroquel XL is being taken to treat major depressive episodes in
major depressive disorder, it will be taken in addition to another drug
being used to treat this illness.
Your doctor may continue to prescribe Seroquel XL even when you are
feeling better.
Do not take Seroquel XL if:
 you are allergic (hypersensitive) to quetiapine or any of the other
ingredients of Seroquel XL (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 XL if the above applies to you. If you are not sure,
talk to your doctor or pharmacist before taking Seroquel XL.
Take special care with Seroquel XL
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.
 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 XL.
 You are an elderly person with dementia. If you are, Seroquel XL
should not be taken because the group of medicines that Seroquel XL
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
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 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 Seroquel XL. 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 because it may affect the way the medicines work. This
includes medicines obtained without a prescription and herbal medicines.
In particular, tell your doctor or pharmacist if you are taking any of the
following medicines:
 Epilepsy medicines (like phenytoin or carbamazepine).
 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
or pharmacist first.
If you have a urine drug screen, taking Seroquel XL 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 XL with food and drink
 Seroquel XL should be taken without food, at least one hour before a
meal or at bedtime.
 Be careful how much alcohol you drink. This is because the combined
effect of Seroquel XL and alcohol can make you sleepy.
