Ganirelix Acetate (Antagon)

Description: Ganirelix Acetate (Antagon) is a gonadotropin releasing hormone with antagonistic (blocking) activity. It is indicated for the inhibition of premature LH (luteinizing hormone) surges in women undergoing controlled ovarian hyperstimulation. Ganirelix Acetate is available as a prefilled syringe containing 250mcg/0.5ml.

How It Works: Ganirelix Acetate is an injectable medication administered subcutaneously. Antagon is administered once daily. It is initiated a few days after FSH (follicle stimulating hormone) therapy and should be continued until the day of HCG administration. Ganirelix Acetate works immediately by suppressing LH and FSH secretion. This allows for eggs to reach the level of development needed for fertilization.  For additional information on administering Ganirelix click here
