How does ORILISSA work?
ORILISSA is a gonadotropin-releasing hormone (GnRH) receptor blocker. It works in the pituitary gland (located at the base of your brain). By blocking GnRH receptors, ORILISSA decreases signals to your ovaries to produce estrogen. This leads to reduced estrogen levels. Your level of estrogen reduction will depend on the dose of ORILISSA you take.
