1. What Letrozole 2.5 mg is and what it is used for
Letrozole 2.5mg 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. Letrozole 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.
Letrozole 2.5mg is used to treat breast cancer in women who have gone through the 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 cases where immediate surgery is not suitable;
• as first treatment after breast cancer surgery;
• following five years treatment with tamoxifen.
Letrozole 2.5mg 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 Letrozole 2.5mg works or why this medicine has been prescribed for you, ask your doctor.
