MYFEMBREE medication information: Relugolix (40 mg) acts by lowering estrogen and progesterone, reducing bleeding from uterine fibroids and pain from endometriosis. Estradiol (1 mg, an estrogen) lowers the risk of bone loss. Norethindrone acetate (0.5 mg, a progestin) lowers the risk of irregular thickening of the womb lining and is necessary when women with a uterus take estrogen.
