A healthcare provider may prescribe Arimidex® (anastrozole) to treat breast cancer in postmenopausal women. This medication, which is taken by mouth (orally) works by blocking certain enzymes in the body that produce estrogen. Because many types of breast cancer need estrogen to grow, Arimidex can help slow down the growth of these cancers.
As an oral medication, Arimidex comes in the form of a tablet, and is typically taken once a day. Your dosage will depend on several factors, such as the severity of your breast cancer and other medications you are taking.
Although most women tolerate this medication well, it is not suitable for everyone. Possible side effects include nausea, hot flashes, and headaches.
