1. Why am I using TEVATIAPINE XR?

TEVATIAPINE XR contains the active ingredient quetiapine fumarate. TEVATIAPINE XR belongs to a group of medicines called antipsychotics.

TEVATIAPINE XR is used to help correct chemical imbalances in the brain. It is used to treat conditions such as:

  • Bipolar disorder, an illness of 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.
  • Recurrent major depressive disorder, an illness where depression is longer lasting and/ or more severe than the “low moods” everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, being unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up early, loss of sex drive, lack of energy and feeling guilty over nothing.
  • Generalised anxiety disorder, where patients have excessive anxiety and worry.
  • Schizophrenia, an illness with disturbances in thinking, feelings and behavior.

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.

4. How do I use TEVATIAPINE XR?

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 or not you are taking any other medicines.
  • Quetiapine modified release tablets are usually started as a low dose that will be 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 (eg liver problems), other medicines you are taking and how you may react to quetiapine modified release tablets. 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.
  • Your doctor may have switched your treatment from quetiapine immediate release tablets to quetiapine modified release tablets. Your doctor will generally prescribe you a once daily dose of quetiapine modified release tablets, which is equivalent to your total daily dose of quetiapine immediate release tablets. Your doctor will tell you how many tablets you will need to take each day.
  • Follow the instructions provided and use TEVATIAPINE XR until your doctor tells you to stop.


  • TEVATIAPINE XR should be taken once a day, at approximately the same time each day.
  • It should be swallowed whole with a full glass of water. Do not split, chew or crush the tablets.
  • It should be taken without food

If you forget to use TEVATIAPINE XR

TEVATIAPINE XR should be used regularly at the same time each day. If you miss your dose at the usual time, take it as soon as you remember, and then go back to taking your medicine as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If you use too much TEVATIAPINE XR

If you think that you have used too much TEVATIAPINE XR, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    by calling 13 11 26, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using TEVATIAPINE XR?

Things you should do

  • Patients (and caregivers of patients) need to monitor for any worsening of their condition and/or the emergence of thoughts of suicide or suicidal behaviour or thoughts of harming themselves and to seek medical advice immediately if these symptoms present.
  • Before your doctor starts you on quetiapine modified release tablets your doctor may want to take some tests (eg blood tests, blood pressure, weight or height measurements). These tests may help to prevent side effects.
  • If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking it.
  • If you become pregnant while taking it, tell your doctor immediately.
  • If you need to have any medical tests (including urine drug screening) while you are taking it, tell your doctor. It may affect the results of some tests.
  • Be sure to keep all of your doctor’s appointments so that your progress can be checked.

Call your doctor straight away 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.

Remind any doctor, dentist or pharmacist you visit that you are using TEVATIAPINE XR.

Things you should not do

  • Do not stop using this medicine suddenly.

  • Do not give this medicine to anyone else, even if their symptoms seem similar or they have the same condition as you.
  • Do not take any medicines that cause drowsiness while you are taking it, unless recommended by your doctor.

Things to be careful of

  • If it 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.
