Cetrorelix is used in women having certain fertility treatments (controlled ovarian stimulation). This medication prevents eggs from being released too early (premature ovulation) by blocking the hormone (gonadotropin-releasing hormone-GnRH) that causes eggs to be released from the ovaries. This gives the eggs time to develop properly.
This medication must not be used if you are already pregnant. Your doctor may order a pregnancy test before your first dose.

Your doctor may direct you to inject a single dose or to inject a smaller dose once daily for several days. The timing of your injection, your dosage, and your length of treatment is based on your medical condition and response to treatment. When an ultrasound shows that you are ready, a second medication (hCG) is usually injected to cause the eggs to mature and release (ovulation).
Be sure to keep all medical appointments so your doctor can closely monitor your response to determine the dosage that is right for you and the time you should use the next medication.
