What Letrozole AN is used for
Letrozole AN is used for the treatment of breast cancer in post-menopausal women i.e. women who no longer have periods, either because of their natural age or following surgery or chemotherapy
Letrozole belongs to a family of medicines called aromatase inhibitors (also referred to as antioestrogens). They function by decreasing the amount of the hormone oestrogen that is produced in your body.
The growth of certain types of breast cancer is promoted by oestrogen.
These cancers are known as “oestrogen-dependent”. Decreasing the production of oestrogen may aid to prevent the cancer from growing.
This might be the first time you are taking an "antioestrogen" such as Letrozole AN or you might have taken another "antioestrogen" such as tamoxifen in the past.
If you have any questions about why Letrozole AN has been prescribed for you, ask your doctor.
You may have been prescribed Letrozole AN by your doctor for another reason.
Letrozole AN is only obtainable with a doctor’s prescription.
Letrozole AN is not addictive.
