It is also used with palbociclib or abemaciclib in women whose disease got worse after treatment with hormone therapy. It is also being studied in the treatment of other types of cancer.

Fulvestrant blocks these proteins and may keep cancer cells from growing. It is a type of antiestrogen. Also called Faslodex and ICI 182780.
