US Brand Names
Fulvestrant injection is used to treat metastatic breast cancer (cancer that has spread) that is hormone-receptor positive in women who have already stopped menstruating (postmenopausal). It is used for women who have breast cancer that has not improved after using other cancer medicines.
Many of the breast cancer tumors will grow when estrogen is available in the body. This medicine blocks the effects of the estrogen hormone in the body. As a result, the amount of estrogen that the tumor is exposed to is reduced, which will limit the growth of the tumor.
This medicine is available only with your doctor's prescription.
