Fibroids / endometriosis (GnRH antagonist)

Relugolix (Relumina, Orgovyx)

Relugolix · レルミナ

Relugolix was developed by Takeda and launched first in Japan as Relumina 40 mg for fibroid and endometriosis pain, taken for up to 6 months. Abroad it is sold combined with add-back hormones (Myfembree, Ryeqo); the Japanese single-agent form is different, so bring your own if mid-course.
