Exemestane is used to treat early and advanced breast cancer in women who have already stopped menstruating (postmenopausal). It is usually used in women who have already received a cancer medication called tamoxifen.

Many breast cancer tumors grow in response to estrogen. Exemestane interferes with the production of estrogen in the body. As a result, the amount of estrogen that the tumor is exposed to is reduced, which will limit the growth of the tumor.

Before you begin treatment with exemestane, you and your doctor should talk about the benefits this medicine will do as well as the risks of using it.

This medicine is available only with your doctor's prescription.

  • Adjuvant therapy in premenopausal women, in combination with ovarian suppression.
  • Prevention of invasive breast cancer in postmenopausal women at increased risk.
