Exemestane tablets

What is this medicine?

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 surgery, radiation, or other cancer medications have been tried without success. Exemestane may also be used for purposes not listed in this medication guide.

What should I tell my health care providers before I take this medicine?

You should not use exemestane if you are allergic to it, or:

• if you are pregnant or able to become pregnant; or

• if you have not yet completed menopause, and are still having menstrual periods.

To make sure exemestane is safe for you, tell your doctor if you have:

• liver disease; or

• kidney disease.

Exemestane can decrease bone mineral density, which may increase your risk of developing osteoporosis. Talk to your doctor about your individual risk of bone loss.

Although it is not likely that a postmenopausal woman would be pregnant, exemestane can cause birth defects. Do not take this medicine if you are pregnant or may become pregnant. Use effective birth control if you are not past menopause, and tell your doctor right away if you become pregnant during treatment.

You may need to have a negative pregnancy test before starting this treatment.
