1. What Anastrozole SUN is and what it is used for
Anastrozole SUN contains a substance called anastrozole and belongs to a group of medicines called 'aromatase inhibitors'. Anastrozole is used to treat breast cancer in women who are post-menopausal.
Anastrozole works by reducing the amount of hormones called oestrogens that your body makes, by blocking a natural substance (an enzyme) called 'aromatase'.
2. What you need to know before you take Anastrozole SUN
Do not take Anastrozole SUN:
??if you are allergic to anastrozole or any of the other ingredients of this medicine (listed in section 6).
- if you are pregnant or breast-feeding (see the section on 'Pregnancy and breast-feeding').
Do not take anastrozole if you are in any of the above situations. If you are not sure, consult your doctor or pharmacist before taking anastrozole.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting Anastrozole SUN:
??if you are still having menstrual periods and have not yet gone through the menopause.
??if you are taking a medicine that contains tamoxifen or medicines that contain oestrogen (see the section on 'Taking Anastrozole SUN with other medicines').
??if you have ever had a condition that affects the strength of your bones (osteoporosis).
??if you have any liver or kidney problems.
If you are not sure if any of these apply to you, consult your doctor or pharmacist before taking Anastrozole.
If you are going to have an operation, tell the doctor or nurse that you are taking anastrozole.
