Anastrozole (an-ASS-troh-zole ) is a medicine that is used to treat breast cancer. Many breast cancer tumors grow in response to estrogen. Anastrozole interferes with the production of estrogen in the body. As a result, the amount of estrogen that the tumor is exposed to is reduced, limiting the growth of the tumor. Anastrozole is available only with your doctor's prescription, in the following dosage form(s): Oral Tablets (U.S. and Canada)
Anastrozole is used to treat advanced breast cancer in postmenopausal women who have failed to respond to therapy with other drugs, such as tamoxifen (Nolvadex). Anastrozole works by decreasing the amount of estrogen your body makes, so that breast cancers which require estrogen for growth may decrease in growth rate and size. Anastrozole is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. Anastrozole comes as a tablet to take by mouth. It usually is taken once a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Anastrozole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Continue to take Anastrozole even if you feel well. Do not stop taking Anastrozole without talking to your doctor.
