What is the difference between emergency contraception and medication abortion?
There is considerable public confusion about the difference between emergency contraception and medication abortion because of misinformation disseminated by anti-choice groups. Emergency contraception helps prevent pregnancy; medication abortion terminates pregnancy. According to general medical definitions of pregnancy that have been endorsed by many organizations including the American College of Obstetricians and Gynecologists and the United States Department of Health and Human Services, pregnancy begins when a pre-embryo completes implantation into the lining of the uterus (ACOG, 1998; DHHS, 1978; Hughes, 1972; “Make the Distinction…,” 2001). Hormonal methods of contraception, including emergency contraception, prevent pregnancy by inhibiting ovulation and fertilization (ACOG, 1998). Medication abortion terminates a pregnancy without surgery.
