Patient Education

Estrogen and Progestin (Transdermal Patch Contraceptives)


Estrogen and progestin transdermal (patch) contraceptives are used to prevent pregnancy. Estrogen (ethinyl estradiol) and progestin (levonorgestrel or norelgestromin) are two female sex hormones. Combinations of estrogen and progestin work by preventing ovulation (the release of eggs from the ovaries) and by changing the cervical mucus and the lining of the uterus. The contraceptive patch is a very effective method of birth control, but it does not prevent the spread of human immunodeficiency virus (HIV; the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.
