What this medicine is used for
The name of your medicine is APO-Olanzapine. It contains the active ingredient olanzapine.
Olanzapine belongs to a group of medicines called antipsychotics. It helps to correct chemical imbalances in the brain, which may cause mental illness.
It is used:
- to treat symptoms of schizophrenia and related psychoses
- alone, or in combination with lithium or valproate, for the short-term treatment of acute manic episodes associated with Bipolar I Disorder.
- as a mood stabiliser that prevents further occurrences of high and low (depressed) extremes of mood associated with Bipolar I Disorder
Schizophrenia is a mental illness with disturbances in thinking, feelings and behaviour. Bipolar I Disorder is a mental illness with symptoms such as feeling “high”, having excessive amounts of energy, needing much less sleep than usual, talking very quickly with racing ideas and sometimes severe irritability.
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.
This medicine may affect your ability to drive a car or operate machinery.
There is no evidence that this medicine is addictive.
Use in children
Olanzapine is not recommended for use in children under the age of 18 years.

How to take this medicine
Follow all directions given to you by your doctor carefully. Their instructions may be different to the information in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much of this medicine you will need to take each day. This will depend on your condition and whether you are taking any other medicines.
The dose your doctor will prescribe for you will usually be in the range of 5 mg to 20 mg per day.
Your doctor may increase or decrease your dose in order to find the appropriate dose for your condition.
A lower starting dose may be prescribed for elderly patients over the age of 65 years
How to take it
Do not handle the orally disintegrating tablet with wet hands. It should be handled carefully with dry hands.
Put the orally disintegrating tablet in your mouth. It will dissolve directly in your mouth, so that it can be easily swallowed.
You can also place the orally disintegrating tablet in a full glass or a cup of water, orange juice, apple juice, milk or coffee, and stir.
Drink it straight away.
With some drinks, the mixture may change colour and possibly become cloudy.
The orally disintegrating tablet should not be placed in cola drinks.
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 it before, with or after food.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
Olanzapine 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, 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 experiencing unwanted side effects.
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 have taken too much olanzapine, the most common signs are fast heartbeat, agitation/ aggression, difficulty speaking, uncontrollable movements and sedation.
While you are taking this medicine
Things you must do
It is important that you remember to take olanzapine daily and at the same dose prescribed by your doctor.
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 become pregnant or start to breastfeed while taking this medicine, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are taking this medicine. Olanzapine may interfere with the results of some tests.

Tell your doctor if you are female and your monthly periods are absent for six months or more.
Keep all of your doctor’s appointments so that your progress can be checked. 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.
Your doctor should monitor you particularly closely in the first weeks that you start taking this medicine.
Your doctor should also monitor your weight while you are taking olanzapine.
Patients with diabetes or who have a higher chance of developing diabetes should have their blood sugar checked often.
If you are over 65, your doctor may measure your blood pressure from time to time.
Things you must not do
Do not stop taking your medicine, or change the dosage, without first checking with your doctor. If you stop taking it suddenly, your condition may worsen, or your chance of getting an unwanted side effect may increase. To prevent this, your doctor will gradually reduce the amount of olanzapine you take each day before stopping the medicine completely.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not take this medicine to treat any other condition unless your doctor tells you to.
Do not take any other 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 olanzapine affects you. Olanzapine may cause drowsiness in some people. If you feel drowsy, do not drive, operate machinery or do anything that could be dangerous.
Be careful when drinking alcohol while taking olanzapine. The effects of alcohol could be made worse while taking olanzapine. Your doctor may suggest you avoid alcohol while being treated with this medicine.
Wear sunscreen and protective clothing if outside, as olanzapine may make your skin more sensitive to the sun. Olanzapine may cause your skin to be much more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness or severe sunburn. If your skin does appear to be burning, tell your doctor.
Make sure you keep cool in hot weather and keep warm in cool weather. Olanzapine may affect the way your body reacts to temperature changes
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking this medicine, or if you have any questions or concerns.
