This medication is used to prevent pregnancy. It is often referred to as the "mini-pill" because it does not contain any estrogen. Norethindrone (a form of progestin) is a hormone that prevents pregnancy.
While the "mini-pill" is more effective than certain other methods of birth control (such as condoms, cervical cap, diaphragm), it is less effective than combination hormone (estrogen and progestin) birth control because it does not consistently prevent ovulation. It is usually used by women who cannot take estrogen. To reduce the risk of pregnancy, it is very important to take this medication exactly as prescribed.
Using this medication does not protect you or your partner against sexually transmitted diseases (such as HIV, gonorrhea, chlamydia). View More Info
