Patient leaflet - Femara 2.5 mg film-coated tablets
1. WHAT FEMARA® IS AND WHAT IT IS USED FOR
What Femara® is and how it works
Femara® contains an active substance called letrozole. It belongs to a group of medicines called aromatase inhibitors.
It is a hormonal (or “endocrine”) breast cancer treatment. Growth of breast cancer is frequently stimulated by oestrogens which are female sex hormones. Femara® reduces the amount of oestrogen by blocking an enzyme (“aromatase”) involved in the production of oestrogens and therefore may block the growth of breast cancer that needs oestrogens to grow. As a consequence tumour cells slow or stop growing and/or spreading to other parts of the body.
What Femara® is used for
Femara® is used to treat breast cancer in women who have gone through menopause i.e cessation of periods.
It is used to prevent cancer from happening again. It can be used as first treatment before breast cancer surgery in case immediate surgery is not suitable or it can be used as first treatment after breast cancer surgery or following five years treatment with tamoxifen. Femara® is also used to prevent breast tumour spreading to other parts of the body in patients with advanced breast cancer.
If you have any questions about how Femara® works or why this medicine has been prescribed for you, ask your doctor.
