Arimidex

Generic name: Anastrozole

Usage of Arimidex

Arimidex 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.

Arimidex is used to treat breast cancer in postmenopausal women.

Arimidex is often given to women whose cancer has progressed even after taking tamoxifen (Nolvadex, Soltamox).

Hormonal cancer treatment can weaken your bones. You may be more likely to have a broken bone while using Arimidex. Talk with your doctor about ways to keep your bones healthy.

Although it is not likely that a postmenopausal woman would be pregnant, anastrozole may harm an unborn baby. You may need to have a negative pregnancy test before starting this treatment. Use effective birth control if you are not past menopause. Keep using birth control for at least 3 weeks after your last dose of Arimidex. Tell your doctor if you become pregnant.
