A healthcare provider may prescribe Arimidex® (anastrozole) to treat breast cancer in postmenopausal women. There is only one form and strength of this medication available.
Available in the form of 1-mg tablets (pills), Arimidex works to slow down the growth of breast cancer by decreasing the amount of estrogen produced by the body. Many breast cancers are sensitive to estrogen and need it in order to grow.
Although most people tolerate this medication well, Arimidex is not suitable for everyone. Possible side effects of the medication include nausea, hot flashes, and headaches. Also, you may not be able to safely use these pills if you have osteoporosis or have not yet gone through menopause.
