What is Faslodex?
Faslodex (fulvestrant) 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 to treat some hormone-related breast cancer.
Faslodex is also used in postmenopausal women whose breast cancer has progressed after treatment with other anti-estrogen medication.
You should not receive Faslodex if you are pregnant.
Before you receive Faslodex, tell your doctor if you have liver disease, a bleeding or blood-clotting disorder, or thrombocytopenia (a low level of platelets in the blood). Also tell your doctor if you are taking a blood thinner such as warfarin (Coumadin, Jantoven).
Call your doctor for instructions if you miss an appointment for your injection.
