Goserelin is injected into the fat tissue of the belly.
Leuprolide is given as a shot under the skin or as a shot in the muscle.
Nafarelin is a nasal spray.
Gonadotropin-releasing hormone agonist (GnRH-a) medicines reduce the amount of estrogen in the body and prevent the release of eggs from the ovaries (ovulation). This stops the monthly menstrual hormonal cycle and results in a condition similar to menopause.
On the rare occasion that a woman is considering removal of the ovaries (oophorectomy), GnRH-a treatment is used beforehand. If GnRH-a treatment relieves symptoms, then removal of the ovaries is likely to provide complete relief from PMS. But even if symptoms improve during GnRH-a treatment, it is possible that the medicine is not the reason for the improvement.
A GnRH-a may be used only for short periods of time (3 to 6 months).
When effective, GnRH-a treatment almost completely ends physical and psychological PMS or PMDD symptoms. (The effectiveness of the nafarelin nasal spray can be hard to predict.) But GnRH-a side effects are usually severe.
