Brand name: Zoladex
Chemical name: Goserelin
How it works: LHRHs shut down the ovaries and stop them from producing estrogen so there is less estrogen to fuel the growth of hormone-receptor-positive breast cancer.
Uses: Zoladex typically is used to reduce the risk of early-stage, hormone-receptor-positive breast cancer coming back in premenopausal women after surgery and other treatments.
How it's given: Zoladex is given as an injection once a month for several months or every few months.
Additional information: Once you stop receiving Zoladex, the ovaries begin functioning again. The time it takes for the ovaries to recover can vary from woman to woman.
