What this medicine is used for
The name of your medicine is APO-Quetiapine. It contains the active ingredient quetiapine (as quetiapine fumarate).
It is used to treat:
the symptoms of schizophrenia, an illness which affects the way people think, feel and act.
Bipolar 1 disorder, an illness in which there are sustained mood swings, either up (mania) or down (depression).
During mania patients experience episodes of overactivity, elation or irritability. During depression patients may feel depressed

from recurring.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed
this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Quetiapine belongs to a group of medicines called antipsychotics.
It helps to correct chemical imbalances in the brain.
There is no evidence that this medicine is addictive.
Use in children
Do not give quetiapine to children or adolescents unless recommended by your doctor.
The effects of quetiapine have only been studied in children aged between 10 and 17 years with bipolar mania and in children
aged between 13 and 17 years with schizophrenia. There is not enough information on its effects in children to recommend use
in other age groups or for other conditions.

How to take this medicine
Follow carefully all directions given to you by your doctor or pharmacist. Their instructions may be different to the information
in this leaflet.
How much to take
Your doctor or pharmacist will tell you how much of this medicine you should take. This will depend on your condition and
whether you are taking any other medicines.
Quetiapine fumarate is usually taken once or twice a day.
If you are elderly or if you have liver problems your doctor may prescribe a lower dose.
Do not stop taking your medicine suddenly or change your dosage without first checking with your doctor.
How to take it
Swallow your tablets whole with a full glass of water.
When to take it
Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also
help you remember when to take it.
It does not matter if you take it before, with or after food.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
Quetiapine helps control your condition, but does not cure it. Therefore you must take it every day.
Do not stop taking it suddenly unless your doctor tells you to - even if you feel better.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose (within 6 hours), skip the missed dose and take your next dose at the usual time.
Otherwise take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
If you take too much (overdose)
If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons
Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your
nearest hospital.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much quetiapine, you may feel drowsy, sleepy, and dizzy or have fast heart beats.
While you are taking this medicine
Things you must do
Tell your doctor that you are taking this medicine if:
you are about to be started on any new medicine
you are pregnant or are planning to become pregnant (tell your doctor immediately).
There have been some reports of side effects such as shaking, muscle stiffness, breathing difficulty and problems feeding
in newborn babies whose mothers have taken quetiapine during the third trimester of pregnancy.
you are breast-feeding or are planning to breast-feed.
Quetiapine is generally not recommended to be taken if you are breast feeding, as the medicine passes into the breast milk.
you are about to have any blood or urine tests
you are going to have surgery or an anaesthetic or are going into hospital.
Your doctor may do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for
a check-up.
If you or someone you know is demonstrating any of the following warning signs of suicide while taking quetiapine, contact
your doctor or a mental health professional immediately or go to the nearest hospital for treatment:
Thoughts or talk of death or suicide
Thoughts or talk of self-harm or harm to others
Any recent attempts of self-harm
Increase in aggressive behaviour, irritability or agitation
Worsening of depression
Occasionally, the symptoms of depression may include thoughts of suicide or self-harm. These symptoms may continue or get
worse during the early stages of treatment until the effect of the medicine becomes apparent.
All mentions of suicide or violence must be taken seriously.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
Things you must not do
Do not:
Give this medicine to anyone else, even if their symptoms seem similar to yours.
Take your medicine to treat any other condition unless your doctor or pharmacist tells you to.
Stop taking your medicine suddenly, or change the dosage, without first checking with your doctor.
If your doctor decides that you need to stop taking quetiapine then he/she will reduce the dose gradually over one to two
weeks.
Things to be careful of
Be careful while driving or operating machinery until you know how quetiapine affects you, as it may impair judgement, thinking
or reactions.
If quetiapine makes you feel light-headed, dizzy or faint, be careful when getting up from a sitting or lying position. Standing
up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood
pressure. If this problem continues or gets worse, talk to your doctor.
Be careful when drinking alcohol while you are taking quetiapine. Combining your medicine and alcohol can make you more sleepy
or dizzy.
Your doctor may suggest you avoid alcohol while you are being treated with this medicine.
Make sure you keep cool in hot weather and warm in cool weather. Take care also if doing strenuous exercise, and be certain
to maintain your fluid levels. Quetiapine may affect the way your body reacts to temperature changes.
Avoid drinking large quantities of grapefruit juice. This medicine may be affected by grapefruit juice.
