Trelstar

Brand name: Trelstar

Chemical name: Triptorelin

Class: LHRH (luteinizing hormone-releasing hormone) agent hormonal therapy. Zoladex and Lupron are also LHRHs.

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: Trelstar typically is used to reduce the risk of early-stage, hormone-receptor-positive breast cancer coming back in pre-menopausal women after surgery and other treatments.

How it's given: Trelstar is given as an injection once a month.

Side effects:

• hot flashes
• mood swings
• loss of libido
• osteoporosis
