1. What Seroquel is and what it is used for
Seroquel contains a substance called quetiapine. This belongs to a
group of medicines called anti-psychotics. Seroquel can be used to
treat several illnesses, such as:
Bipolar depression: where you feel sad. You may find that you feel
depressed, feel guilty, lack energy, lose your appetite or can’t sleep.
Mania: where you may feel very excited, elated, agitated,
enthusiastic or hyperactive or have poor judgment including being
aggressive or disruptive.
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.

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 or Lithium (other anti-psychotic medicines).
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).
Medicines that can cause constipation.
Medicines (called ‘anti-cholinergics’) that affect the way nerve cells
function in order to treat certain medical conditions.
Before you stop taking any of your medicines, please talk to your doctor
first.

Your doctor may continue to prescribe Seroquel even when you are
feeling better.
2. What you need to know 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).
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).
Do not take Seroquel if the above applies to you. If you are not sure,
talk to your doctor or pharmacist before taking Seroquel.
Warnings and Precautions
Talk to your doctor or pharmacist before taking Seroquel if:
You, or someone in your family, have or have had any heart
problems, for example heart rhythm problems, weakening of the
heart muscle or inflammation of the heart 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
Seroquel.
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, 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.
You have or have had a condition where you stop breathing for short
periods during your normal nightly sleep (called ‘sleep apnoea’) and
are taking medicines that slow down the normal activity of the brain
(‘depressants’).
You have or have had a condition where you can’t completely empty
your bladder (urinary retention), have an enlarged prostate, a
blockage in your intestines, or increased pressure inside your eye.
These conditions are sometimes caused by medicines (called ‘anticholinergics’) that affect the way nerve cells function in order to treat
certain medical conditions.
Tell your doctor immediately if you experience any of the following after
taking Seroquel:
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 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.
Tell your doctor as soon as possible if you have:
A fever, flu-like symptoms, sore throat, or any other infection, as
this could be a result of a very low white blood cell count, which
may require Seroquel to be stopped and/or treatment to be given.
Constipation along with persistent abdominal pain, or constipation
which has not responded to treatment, as this may lead to a more
serious blockage of the bowel.
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.

Seroquel with food, drink and alcohol
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 sleepy.
Do not drink grapefruit juice while you are taking Seroquel. It can
affect the way the medicine works.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or
planning to have a baby ask your doctor for advice before taking
Seroquel. You should not take Seroquel during pregnancy unless this
has been discussed with your doctor. Seroquel should not be taken if
you are breast-feeding.
The following symptoms which can represent
withdrawal may occur in newborn babies of mothers that have used
Seroquel 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.
Seroquel contains lactose
Seroquel contains lactose which is a type of sugar. If you have been
told by your doctor that you have an intolerance to some sugars, talk to
your doctor before taking this medicine.
Effect on Urine Drug Screens
If you are having a urine drug screen, taking Seroquel may cause
positive results for methadone or certain drugs for depression called
tricyclic antidepressants (TCAs) when some test methods are used,
even though you may not be taking methadone or TCAs. If this
happens, a more specific test can be performed.
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. The maintenance dose (daily dose)
will depend on your illness and needs but will usually be between
150mg and 800mg.
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.
You can take your tablets with or without food.
Do not drink grapefruit juice while you are taking Seroquel. It can
affect the way the medicine works.
Do not stop taking your tablets even if you feel better, unless your
doctor tells you.
Liver problems
If you have liver problems your doctor may change your dose.
Elderly people
If you are elderly your doctor may change your dose.
Use in children and adolescents
Seroquel should not be used by children and adolescents aged under
18 years.
If you take more Seroquel than you should
If you take more Seroquel than prescribed by your doctor, you may feel
sleepy, feel dizzy and experience abnormal heart beats. Contact your
doctor or nearest hospital straight away. Keep the Seroquel tablets with
you.
If you forget to take a dose of Seroquel
If you forget to take a dose, take it as soon as you remember. If it is
almost time to take the next dose, wait until then. Do not take a double
dose to make up for a forgotten tablet.

If you stop taking Seroquel
If you suddenly stop taking Seroquel, you may be unable to sleep
(insomnia), or you may feel sick (nausea), or you may experience
headache, diarrhoea, being sick (vomiting), dizziness or irritability. Your
doctor may suggest you reduce the dose gradually before stopping
treatment.

doctor or pharmacist.
