6 Contents of the pack and other information.
1. what anastrozole is and what it is used for
Anastrozole tablets contain a substance called anastrozole. This belongs to a group of medicines called ‚aromatase inhibitors‘. Anastrozole tablets are used to treat breast cancer in women who have gone through the menopause.
Anastrozole works by cutting down the amount of hormone called oestrogen that your body makes. It does this by blocking a natural substance (an enzyme) in your body called ‚aromatase‘.
2. what you need to know before you take anastrozole
Do not take Anastrozole:
- if you are allergic (hypersensitive) to anastrozole or any of the other ingredients of this medicine (listed in section 6, Contents of the pack and other information).
- if you are pregnant or breast-feeding (see section called ‚Pregnancy and breast-feeding‘).
Do not take Anastrozole if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Anastrozole.
Warnings and precautions
Talk to your doctor, or pharmacist or nurse before taking this medicine:

- if you have ever had a condition that affects the strength of your bones (osteoporosis)
- if you have problems with your liver or kidneys.

Other medicines and Anastrozole
Please tell your doctor or pharmacist if you are taking or have recently taken any othermedicines, including medicines obtained without a prescription.

If this applies to you, ask your doctor or pharmacist for advice.
Tell your doctor or pharmacist if you are taking the following:
