Norgestrel in combination with ethinyl estradiol is used for the prevention of pregnancy in women who elect to use this product as a method of contraception.

Norestra is also used to associated treatment for these conditions: Abnormal Uterine Bleeding, Endometriosis, Hypermenorrhea, Menstrual Distress (Dysmenorrhea), Polycystic Ovarian Syndrome, Emergency Contraception, Oral Contraceptives

How Norestra works

Norgestrel (and more specifically the active stereoisomer levonorgestrel) binds to the progesterone and estrogen receptors within the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like levonorgestrel will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge. Loss of the LH surge inhibits ovulation and thereby prevents pregnancy.
