How effective is medication abortion?
EC is very effective at reducing the risk of pregnancy. Studies have shown EC reduces the risk of pregnancy when taken up to 120 hours after unprotected intercourse, but the sooner the dosing begins, the more effective the treatment. When taken within 72 hours of unprotected intercourse, EC that contains both estrogen and progestin reduces the risk of pregnancy by 75 percent. Within the same time frame, progestin-only regimens, such as Plan B, reduce the risk of pregnancy by 89 percent. When initiated within 24 hours of unprotected intercourse, progestin-only EC was found to reduce the risk of pregnancy by 95 percent (Ellertson et al., 2003; Rodrigues et al., 2001; TFPMFR, 1998; Van Look & Stewart, 1998). Medication abortion regimens are highly effective at ending very early pregnancies. Complete abortion will occur in 9296 percent of women receiving the methotrexate regimen. Complete abortion will occur in 9697 percent of women receiving the mifepristone regimen.

ECPs are very effective at reducing the risk of pregnancy. Studies have shown ECPs reduce the risk of pregnancy when taken up to 120 hours after unprotected intercourse, but the sooner the dosing begins, the more effective the treatment. When taken with 72 hours of unprotected intercourse, ECPs that contain both estrogen and progestin, such as Preven, reduce the risk of pregnancy by 75 percent. Within the same time frame, progestin-only regimens, such as Plan B, reduce the risk of pregnancy by 89 percent. When initiated within 24 hours of unprotected intercourse, progestin-only ECPs were found to reduce the risk of pregnancy by 95 percent (Ellertson, et al, 2001; Rodrigues, et al, 2001; TFPMFR, 1998; Van Look & Stewart, 1998) .
