Ganirelix Acetate is a daily subcutaneous (under the skin) injection that is prescribed to women undergoing ovarian stimulation during IVF. Ganirelix belongs to a class of medications called "GnRH antagonists” which are used to block the production of Luteinizing Hormone (LH). Because LH is the hormone that triggers ovulation, Ganirelix injections prevent the eggs that are growing in the ovaries from ovulating (releasing) prior to the egg retrieval, called “premature ovulation". Ganirelix is typically started in the middle of ovarian stimulation (day 5 or 6) and taken until the day of the trigger shot.
Ganirelix Acetate comes in a disposable, ready-to-use prefilled syringe that requires no mixing before injection.

Tell your doctor if you have a latex allergy before you start using this medicine. A serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms such as: rash, swelling of the face, lips, tongue, or throat, severe dizziness, or trouble breathing. This is not a complete list of side effects that may occur. If you are concerned about side effects, discuss the risks and benefits of this medication with your doctor. You may report side effects to the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Some women using Ganirelix Acetate develop ovarian hyperstimulation syndrome (OHSS) during or shortly after treatment. OHSS can be life threatening.
