Ganirelix belongs to a group of medicines called “antigonadotrophin-releasing hormones. It is used in women undergoing certain fertility treatments. It acts by blocking the release of luteinizing hormone (LH) thus preventing the early release of eggs and giving them the time to grow properly. It is usually used in combination with other medicines.

It is given as an injection, only at a hospital or clinic by a medical healthcare professional. The patient may be monitored regularly for the follicular development. The treatment duration depends on the ovarian response of the patient.

If these persist consult your doctor. In addition, conditions like ovarian hyperstimulation syndrome (OHSS), and multiple births or birth defect may also be associated with the use of this medicine.
