What is Cetrotide?


Cetrotide® (cetrorelix) is a gonadotropin-releasing hormone (GnRH) antagonist drug that can be used in the treatment of infertility. Infertility is described as the inability to conceive a baby within one year of trying. Cetrotide® is a synthetic (man-made) hormone that inhibits early luteinizing hormone (LH) surges in females undergoing a fertility procedure called ovarian hyperstimulation. An LH surge normally causes ovulation (release of the egg), but it is stopped by Cetrotide® until the conditions are right for the fertilization procedure to begin.

Cetrotide® side effects

Side effects of Cetrotide® include injection site redness, itching, swelling, bruising; headache; and nausea. You should notify your doctor immediately if you experience more serious side effects such as severe abdominal pain, nausea and vomiting, rapid weight gain, bloating, swelling, or shortness of breath. If you are having difficulty becoming pregnant, be sure to talk to your doctor about what the best treatment is for you.
