What is exemestane (Aromasin)?

Exemestane lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body.

Exemestane is used to treat breast cancer in postmenopausal women. It is often given to women whose cancer has progressed even after taking tamoxifen (Nolvadex, Soltamox) for 2 to 3 years.

Exemestane may also be used for other purposes not listed in this medication guide.
