Myfembree (Relugolix/Estradiol/Norethindrone Acetate)

Drug:Myfembree (Available Soon)
Dosage:40 mg/1 mg/0.5 mg

Myfembree (Relugolix/Estradiol/Norethindrone Acetate) is a prescription medication used to treat heavy menstrual bleeding associated with uterine leiomyomas (fibroids). It is also effective in managing moderate to severe pain in women diagnosed with endometriosis. Endometriosis is a condition in which endometrial tissues are found outside the uterus, resulting in painful menstruation, heavy menstrual flow, and postcoital bleeding. The active ingredients in Myfembree are Relugolix, Estradiol, and Norethindrone Acetate. Myfembree belongs to the class of medication called gonadotropin-releasing hormone antagonists (GnRH antagonists). It works by binding and blocking GnRH receptors in the anterior pituitary gland. As a result, it decreases the release of gonadotropins (i.e., luteinizing hormone, follicle-stimulating hormone), thereby decreasing the downstream production of estrogen and progesterone by the ovaries in women.

Estradiol and norethindrone may decrease breast milk production. A small amount of estradiol and norethindrone passes into breast milk and may have undesirable effects on a nursing infant.

Your doctor will conduct a pregnancy test for you before starting you on Myfembree tablets.

Use a barrier contraceptive such as a condom while using Myfembree tablet and a week after stopping it. It is often recommended not to use Myfembree for more than 2 years due to the risk of continued bone loss that may not be reversible. Inform your doctor if there is no improvement in your condition.
