It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

What AZASTROLE is used for

AZASTROLE is used to treat breast cancer in women who no longer have their menstrual periods either naturally, due to their age or after surgery, radiotherapy or chemotherapy.

AZASTROLE is a non-steroidal aromatase inhibitor, which reduces the amount of oestrogen (female sex hormone) made by the body. In some types of breast cancer, oestrogen can help the cancer cells grow. By blocking oestrogen, AZASTROLE may slow or stop the growth of cancer.

Follow all directions given to you by your doctor. They may differ from the information contained in this leaflet.

Ask your doctor if you have any questions about why AZASTROLE has been prescribed for you. Your doctor may have prescribed AZASTROLE for another reason.

AZASTROLE is only available with a doctor's prescription.

AZASTROLE is not addictive

Do not take AZASTROLE if you have an allergy to:

  • Anastrozole, the active ingredient of AZASTROLE.

Before you start to take it

Tell your doctor if you have any allergies to the following:

  • Liver problems;
  • Kidney problems; or

Aromatase inhibitors may decrease bone mineral density (BMD) in women who have been through menopause, with a possible increased risk of fractures. Your doctor should discuss with you, your treatment options for managing this possible increased risk of fractures.

If you have not told your doctor about any of the above, tell him/her before you start taking AZASTROLE.

How to take AZASTROLE

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

Your doctor or pharmacist will tell you how many tablets you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

The usual dose is one tablet every day.

When to take it

Take AZASTROLE 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.

Swallow AZASTROLE tablets whole, with a glass of water.

It does not matter if you take AZASTROLE before, with or after food.

How long to take it

Continue taking AZASTROLE for as long as your doctor or pharmacist tells you. AZASTROLE helps to control your condition, but does not cure it. Therefore you must take AZASTROLE every day. Do not stop taking it unless your doctor tells you to – even if you feel better.

If you forget to take it

If you miss a dose, take it as soon as you remember, as long as it is 12 hours before the next dose is due. If it is less than 12 hours to the next dose, do not take the dose you have missed.

Do not double the 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 when 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 (Australia 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 AZASTROLE. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
