Arimidex Overview

Arimidex (generic: anastrozole) is a prescription medication used to treat breast cancer in postmenopausal women. It specifically treats hormone receptor-positive tumors that are fueled by estrogen. Arimidex belongs to a group of drugs called aromatase inhibitors. These medications work by blocking an enzyme called aromatase that helps your body make estrogen. 

Arimidex comes in tablet form and is usually taken once a day, with or without food.
Common side effects of Arimidex include hot flashes, weakness, joint pain, headache, and swelling.
