What Femara is used for
Femara is used to treat breast cancer in women who are post-menopausal - that is,
women who no longer have periods, either naturally due to their age or after surgery
Femara is available in tablets containing 2.5 mg of the active ingredient, letrozole.
Letrozole belongs to a family of medicines called aromatase inhibitors. They are also
called "antioestrogens" because they act by reducing the production of oestrogen in
Oestrogen stimulates the growth of certain types of breast cancer. These cancers are
called "oestrogen-dependent." Reducing the production of oestrogen may help to keep
the cancer from growing.
This may be the first time you are taking an "antioestrogen" such as Femara or you
may have taken another "antioestrogen" such as tamoxifen in the past.
Ask your doctor if you have any questions about why Femara has been prescribed for
Your doctor may have prescribed Femara for another reason.
Femara is only available with a doctor's prescription. It is not addictive.
