How to take IBRANCE
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 instructions on the label, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you which strength of IBRANCE capsules you need to take. This may depend on your age, your condition and whether or not you are taking any other medicines.
For advanced breast cancer the recommended dose of IBRANCE is one 125 mg capsule taken once daily for 21 days followed by 7 days without taking IBRANCE.
Your doctor may change your dose during treatment.
Taking IBRANCE for 21 continuous days followed by 7 days without taking IBRANCE (total of 28 days) is counted as one treatment cycle.
The 7 day break when you are not taking IBRANCE helps your body recover. It reduces your chance of getting side effects and could stop you getting an infection.
How to take it
Swallow the IBRANCE capsules whole with a glass of water.
When to take it
You should take IBRANCE with food and at the same time each day. Taking it with food and at the same time each day will have the best effect. It will also help you remember when to take it.
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 or vomit after taking a dose
Take your next dose at your regular time.
Do not take a double dose to make up for the dose that you missed.
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 Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764 766) 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 IBRANCE.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are using IBRANCE
Things you must do
Make sure you follow your doctor's instructions and keep all appointments.
You should have a blood test before each treatment cycle. The blood test is done to make sure your blood cells have recovered from the last treatment cycle and to check for side effects.
Tell your doctor immediately if you experience signs or symptoms of an infection such as fever and chills. IBRANCE may reduce the number of your white blood cells and weaken your immune system. You may be at greater risk of getting an infection while you are taking IBRANCE.
Use contraception (birth control) to prevent pregnancy while you are being treated with IBRANCE. Women who could become pregnant or men who could father a child must use a reliable method of contraception during treatment with IBRANCE. Women should continue using contraception for at least a month after taking their last dose of IBRANCE and males should continue using contraception for 14 weeks after the last dose of IBRANCE.
Tell your doctor immediately if you become pregnant while taking IBRANCE.
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.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking IBRANCE.
Things you must not do
Do not eat grapefruit or drink grapefruit juice while you are being treated with IBRANCE. Grapefruit and grapefruit juice may change the amount of IBRANCE in your body.
Do not take IBRANCE to treat any other complaints unless your doctor tells you to.
Do not give IBRANCE to anyone else, even if they have the same condition as you.
Do not stop taking IBRANCE or lower the dosage without checking with your doctor.
Things to be careful of
Be careful driving or operating machinery until you know how IBRANCE affects you. This medicine may cause fatigue and blurred vision in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Like all medicines, IBRANCE can cause side effects.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking IBRANCE.
Do not be alarmed by the list of side effects. You may not experience any of them.

- hair loss
- loss of appetite
- nose bleed

The above side effects may be serious. You may need urgent medical attention or hospitalisation.
Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may also occur in some people.
Some side effects can only be found when your doctor does tests to check your progress. These tests could show a reduction in white blood cells, red blood cells or platelets. These tests could also show a change in liver enzymes.
After using IBRANCE
Keep your capsules in the pack until it is time to take them. If you take the capsules out of the pack they may not keep well.
Keep your capsules in a cool dry place where the temperature stays below 30°C.
Do not store IBRANCE or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor tells you to stop taking this medicine or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
