US Brand Name
Fulvestrant injection is used to treat hormone-receptor positive metastatic breast cancer (cancer that has spread) in postmenopausal women that have received other cancer medicines that did not work well. This medicine is also used in combination with palbociclib to treat HR positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer in women who have received hormonal therapy.
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 to be given only by or under the direct supervision of your doctor.
