What is in this leaflet

This leaflet answers some common questions about this medicine. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.

What this medicine is used for

Quetiapine is used to treat conditions such as:
schizophrenia, an illness with disturbances in thinking, feelings and behaviour
bipolar 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 whilst during depression, patients may feel depressed or guilty, lack energy, lose their appetite and have trouble sleeping
Quetiapine belongs to a group of medicines called antipsychotics. It helps to correct chemical imbalances in the brain.
Ask your doctor if you have any questions about why it has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
You may find it helpful to tell a friend or relative that you are suffering from these symptoms and ask them to read this leaflet. You might ask them to tell you if they think your symptoms are getting worse, or if they are worried about any other changes in your behaviour.
This medicine is not addictive.
This medicine is available only with a doctor's prescription

Before you take this medicine

When you must not take it

Do not take this medicine if you have an allergy to:
any medicine containing quetiapine
any of the ingredients listed at the end of this leaflet
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, itching or hives on the skin
Do not give this medicine 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 mania, and in children aged between 13 and 17 years with schizophrenia. There is not enough information on its effects in children to recommend its use in other age groups or for other conditions.
Do not give this medicine to elderly patients unless recommended by your doctor.
Quetiapine, as with other anti- psychotic medicines, is recommended for use with caution in the elderly and is not approved for treatment of dementia and behavioural disturbances. Clinical studies with this group of medicines for the treatment of dementia and behavioural disturbances in the elderly have suggested an increased risk of cardiovascular adverse events (including stroke) and an increased mortality risk for elderly patients.
Do not take this medicine if you are pregnant.
It is not known if it is safe for you to take quetiapine while you are pregnant as it may affect your developing baby. However, if you need to take it during your pregnancy, your doctor will discuss the risks and benefits of taking it with you.
Do not breastfeed if you are taking this medicine.
It is recommended that you do not breastfeed while taking it, as quetiapine may pass into breast milk and there is a possibility that your baby may be affected.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have or have had any of the following medical conditions:
heart or blood vessel problems or a family history of heart or blood vessel problems including low blood pressure, stroke, problems with the way your heart beats, a history of heart attack, problems with your circulation or any condition that affects blood flow to the brain
liver problems
diabetes or a family history of diabetes – patients with diabetes, or who have a higher chance of diabetes should have their blood sugar checked before and during treatment with quetiapine
epilepsy (seizures or fits)
dementia or related behavioural disorders (especially in elderly patients)
low white blood cell count
sleep apnoea – a condition where you stop breathing for short periods during your normal nightly sleep
urinary retention – a condition where you can't completely empty your bladder
an enlarged prostate
a blockage in your intestines
increased pressure inside your eyes or glaucoma
history of alcohol or drug abuse
Tell your doctor or mental health professional if you have any mental/mood changes or suicidal thoughts.
Depression and other mental illnesses can increase the risk of suicide. It is important to discuss all the risks of treating depression and mental illness as well as the risks of not treating it. You should discuss all treatment choices with your doctor, not just the use of antidepressants.
Patients (and caregivers of patients) need to monitor for any signs of worsening condition and/or the emergence of thoughts of suicide, suicidal behaviour or thoughts of self-harm and to seek medical advice immediately if these symptoms present.
Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding.
Your doctor can discuss with you the risks and benefits involved.
Tell your doctor if you are lactose intolerant.
This medicine contains lactose.
If you have not told your doctor about any of the above, tell them before you start taking this medicine.
Before starting on quetiapine your doctor may want to take some tests (such as blood tests, blood pressure, weight or height measurements). These tests may help to prevent side effects.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and quetiapine may interfere with each other. These include:
medicines used to treat anxiety, depression, mood swings, attention deficit hyperactivity disorder (ADHD) or other mood disorders
lorazepam, used to help you sleep
phenytoin or carbamazepine, used for epilepsy
medicines for high blood pressure (including diuretics/fluid tablets) or heart conditions
some antibiotics such as rifampicin and erythromycin
medicines used for fungal infections such as ketoconazole
medicines for Human Immunodeficiency Virus (HIV)
thioridazine, an antipsychotic medicine
medicines used to treat Parkinson's disease
stimulants such as amphetamines
glucocorticoids, used to treat inflammation.
medicines that have anticholinergic (muscarinic) effects
These medicines may be affected by quetiapine or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the directions, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you how many tablets you will need to take each day and how long you need to take it.
This depends on your condition and whether you are taking any other medicines.
Quetiapine is usually started as a low dose that will be gradually increased by your doctor. Your doctor will recommend a dose especially for you. This will depend on various factors including your age, condition being treated, other medical conditions (e.g. liver problems), other medicines you are taking and how you may react to quetiapine. Your doctor will monitor your condition and may change your dose depending on how you respond to it. Your doctor will use the lowest dose for the least amount of time to keep you well.
Quetiapine is taken once or twice a day depending on your condition.

How to take it

Swallow the tablets whole with a full glass of water.

When to take it

Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take this medicine before or after food.

How long to take it

Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your condition but does not cure it. It is important to keep taking your medicine even if you feel well.

If you forget to take it

If it is almost time to take your next dose (within 6 hours), skip the dose you missed and take your next dose when you are meant to.
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 the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too many quetiapine tablets you may feel drowsy, sleepy, dizzy or have fast heart beats.

While you are taking this medicine

Things you must do

Tell your doctor or mental health professional immediately, or go to the nearest hospital, if you have any of the following suicidal thoughts or other mental/mood changes:
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.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.
It may affect other medicines used during surgery.
If you become pregnant or start to breastfeed while taking this medicine, tell your doctor immediately.
If you are about to have any urine or blood tests, tell your doctor that you are taking this medicine.
It may interfere with the results of some tests.
Keep all your doctor's appointments so that your progress can be checked.
Your doctor may do some tests from time to time (e.g. blood tests, blood pressure, weight or height measurements) to make sure the medicine is working and to prevent unwanted side effects.

Things you must not do

Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.
If you stop taking quetiapine suddenly, your condition may worsen or your chance of getting an unwanted side effect may increase. To prevent this, your doctor may gradually reduce the amount of quetiapine you take each day before stopping completely.
Do not take any medicines that cause drowsiness while you are taking this medicine, unless recommended by your doctor.

Things to be careful of

Be careful driving or operating machinery until you know how this medicine affects you.
This medicine may cause dizziness, or drowsiness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous. Children should be careful when riding bicycles or climbing trees.
Be careful when drinking alcohol while you are taking this medicine.
If you drink alcohol, the symptoms of dizziness and drowsiness may be worse. Your doctor may suggest you avoid alcohol while you are being treated with quetiapine.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
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.
Avoid getting over-heated or dehydrated.
Do not over-exercise. In hot weather, stay inside in a cool place (stay out of the sun), do not wear too much or heavy clothing and drink plenty of water. Keep warm in cool weather.
Quetiapine may affect the way your body reacts to temperature changes.
Avoid drinking large quantities of grapefruit juice.
Quetiapine may be affected by grapefruit juice. Talk to your doctor or pharmacist if you have any concerns.
