About anastrozole
Some breast cancers need the hormone oestrogen to grow. In women who have had their menopause, the main source of oestrogen is through the change of androgens (sex hormones) into oestrogens. Anastrozole works by preventing this change therefore reducing the amount of oestrogen in the body..

Before taking anastrozole
Before taking anastrozole make sure your doctor or pharmacist knows:.

If you are pregnant, trying for a baby or breast-feeding.
If you suffer from liver or kidney problems.
If you have not gone through the menopause.
If you have a family history of osteoporosis (bone thinning).
If you are taking oestrogen-containing medicines, for example hormone replacement therapy.
If you are taking tamoxifen.

Anastrozole should not be given to children

How to take anastrozole
Take your medication exactly as directed by your doctor. Try to take your tablet at the same time each day. Swallow the tablet whole with a drink of water. If you miss a dose don't worry, just wait until the next dose is due.

Getting the most from your treatment
Do not stop taking anastrozole even if you are feeling well, unless your doctor tells you to.

Before having any kind of medical treatment, including dental or emergency treatment, tell the doctor, surgeon, dentist, or other medical professional, that you are taking anastrozole.

Keep your regular appointments with your doctor so your progress can be monitored.
