How Does Letrozole Work?

By inhibiting the aromatase enzyme, letrozole reduces the amount of estrogen produced by the ovaries and other tissues. This reduction is particularly beneficial for women whose breast cancer is stimulated by estrogen.

Letrozole is primarily prescribed for:
- Adjuvant treatment after surgery for early-stage hormone receptor-positive Letrozol Mylan 2.5mg breast cancer.
