What LETROZOLE FBM is used for
LETROZOLE FBM 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 or chemotherapy.
LETROZOLE FBM belongs to a group of medicines called aromatase inhibitors also called ‘antioestrogens’. These medicines work by reducing the production of oestrogen in your body.
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 LETROZOLE FBM or you may have taken another "antioestrogen" such as femara or tamoxifen in the past.
Your doctor may have prescribed LETROZOLE FBM for another reason. Ask your doctor if you have any questions about why LETROZOLE FBM has been prescribed for you.
LETROZOLE FBM is available only with a doctor's prescription.
There is no evidence that LETROZOLE FBM is addictive.
