Ganirelix is used in the treatment of female infertility and prostate cancer.
How Ganirelix works In females undergoing treatment for infertility, premature ovulation can sometimes lead to the release of eggs that are not ready for fertilization. Ganirelix blocks the action of a natural hormone, preventing the premature release of eggs from the ovary.
Common side effects of Ganirelix include abdominal pain, headache, ovarian hyperstimulation syndrome, vaginal bleeding, injection site reaction, nausea, and death.
