Fulvestrant is used to treat hormone receptor-positive breast cancer in women who have experienced menopause.
Fulvestrant is an estrogen receptor antagonist. Some types of breast cancer cells depend on estrogen to grow. Fulvestrant blocks the activity of estrogen on cancer cells. This impact can stop or slow the growth of breast cancer that requires estrogen.
A liquid solution, fulvestrant is injected into a muscle in the buttocks. Usually, fulvestrant is given once a month. The dose may be given all at once, or it may be divided into two injections.
