What this medicine is used for
The name of your medicine is Terry White Chemists Quetiapine tablets. 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 behave.
- 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 or guilty, lack energy, lose their appetite and have trouble sleeping. Quetiapine may both treat and prevent bipolar disorder 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 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. Their instructions may be different to the information in this leaflet.
How much to take
Your doctor 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. Your doctor will monitor your condition and may change your dose depending on how you respond to it.
Do not stop taking your medicine 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
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, 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)
- you are breastfeeding or are planning to breast-feed
- 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 occasionally 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
- 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 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.
- Take any other medicines that cause drowsiness while you are taking quetiapine, unless recommended by a doctor.
Things to be careful of
Be careful when driving or operating machinery until you know how this medicine 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.
