Norgestrel is primarily used in hormonal contraceptives, often combined with estrogen, to prevent pregnancy by inhibiting ovulation, altering the cervical mucus, and changing the endometrial lining. It is also utilized in hormone replacement therapy to manage symptoms of menopause, such as hot flashes and vaginal dryness. Additionally, norgestrel can be prescribed to treat menstrual disorders, including irregular periods and severe menstrual pain, as well as endometriosis to reduce symptoms. It is effective in emergency contraception when taken shortly after unprotected intercourse and for managing abnormal uterine bleeding. Its progestogenic properties make it valuable in regulating hormonal imbalances and supporting reproductive health.
