What is Faslodex?

Faslodex is an anti-estrogen medication. It works by blocking the actions of estrogen in the body. Certain types of breast cancer use estrogen to grow and multiply in the body.

Faslodex is used in postmenopausal women with hormone-related breast cancer that is advanced or has spread to other parts of the body (metastatic).

Faslodex is used alone or in combination with another medicine called ribociclib (Kisqali) to treat HR-positive, HER2-negative breast cancer in:

• women with no prior treatment; or

• women whose cancer has progressed after treatment with anti-estrogen medication.

Faslodex is used in combination with palbociclib (Ibrance) or abemaciclib (Verzenio) when the cancer has progressed after treatment with anti-estrogen medication.
