What is Letrozol Normon and how does it work
This medicine contains the active substance letrozole. It belongs to a group of medicines called aromatase inhibitors. It is a hormonal (or "endocrine") treatment for breast cancer. The growth of breast cancer is often stimulated by estrogens, which are female sex hormones. Letrozole reduces the amount of estrogen by blocking an enzyme (aromatase) involved in estrogen production, and can therefore block the growth of breast cancers that need estrogens to grow. As a result, tumor cells grow more slowly or stop growing and/or spreading to other parts of the body.
What is Letrozol Normon used for
This medicine is used to treat breast cancer in women who have passed the menopause, i.e., the cessation of menstrual periods.
It is used to prevent breast cancer from coming back. It can be used as the first treatment before breast cancer surgery, if surgery is not immediately possible, or it can be used as the first treatment after breast cancer surgery, or after five years of treatment with tamoxifen. Letrozole is also used to prevent the breast tumor from spreading to other parts of the body in patients with advanced breast cancer.
If you have any questions about how letrozole works or why you have been prescribed it, ask your doctor.
Follow carefully all instructions given to you by your doctor. They may differ from the general information contained in this leaflet.
