The recent availability of 2 new hormonal regimens for postcoital
emergency contraception (EC) is significant for patients who have
unintended unprotected intercourse. While the recently FDA-approved
abortifacient mifepristone (Mifeprex) ends pregnancy, EC probably
prevents pregnancy from occurring. The precise mechanism of action
of EC drugs is not fully understood, but they could inhibit or
delay ovulation, prevent union of sperm and ovum, or alter the
endometrium, making it inhospitable to a fertilized ovum. The
copper-bearing intrauterine device (IUD) is also an EC option.
*The treatment schedule is one dose within 72 h after
unprotected intercourse and another dose 12 h later.
ÝThe progestin in Lo/Ovral, Low-Ogestrel, Ogestrel, Ovral,
and Ovrette is norgestrel, which contains 2 isomers, only 1 of
which (levonorgestrel) is bioactive; the amount of norgestrel
in each dose is twice the amount of levonorgestrel.
¦Plan B and Preven are the only products specifically FDA-approved
for emergency contraception (EC). Alesse, Levlen, Levlite, Levora,
Lo/Ovral,
Low-Ogestrel, Nordette, Ogestrel, Ovral, Tri-Levlen, Triphasil,
and Trivora have been declared safe and effective for use as EC
medications by the FDA.
