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 or chemotherapy.
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 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 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 you.
Your doctor may have prescribed Femara for another reason.
Femara is only available with a doctor's prescription. It is not addictive.

Do not take Femara if you are still having periods. This medicine is only used in women who are no longer having periods.
Women of child-bearing age who recently became postmenopausal or perimenopausal should use a proven method of birth control to avoid pregnancy, until your postmenopausal status is fully established.
Do not take Femara if you are pregnant or breast feeding. It may affect your baby if you take it while you are pregnant or breast feeding.

Tell your doctor if you have severe kidney or liver disease. Your doctor may want to take special precautions while you are taking this medicine.
Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives. Your doctor will want to know if you are prone to allergies.
If you have not told your doctor about any of these things, tell them before you take Femara.
Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop. Other medicines may be affected by Femara or they may affect how well it works.
