What is Letrozol STADA and how it works

Letrozol STADA contains an active ingredient called letrozol. It belongs to a group of medicines called aromatase inhibitors. It is a hormone (endocrine) treatment for breast cancer. The growth of breast cancer is usually stimulated by estrogens, which are the female sex hormones. Letrozol reduces the amount of estrogen by blocking an enzyme (aromatase) involved in estrogen production, and therefore can 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 STADA used for

Letrozol is used to treat breast cancer in women who have passed menopause, that is, the cessation of menstrual periods.

It is used to prevent breast cancer from recurring. It can be used as the first treatment before breast cancer surgery, if immediate surgery is not suitable, or it can be used as the first treatment after breast cancer surgery, or after five years of treatment with tamoxifen. Letrozol is also used to prevent breast cancer from spreading to other parts of the body in patients with advanced breast cancer.

If you have any questions about how letrozol works or why you have been prescribed this medicine, consult your doctor.

Follow carefully all the instructions given by your doctor. They may be different from the general information contained in this leaflet.
