JCP, Didn't the whole "Plan B" plan come out of the fact that doctors were just advising their patients to take an "overdose" of birth control pills following intercourse to prevent unwanted pregnancies? en.wikipedia.org (under "Types of ECPs") Emergency hormonal contraception is available in two main forms: the original version is the combined or Yuzpe regimen which uses large doses of both estrogen and progesterone taken as two doses at 12 hour intervals. This technique is believed to be approximately 75% effective depending on how soon it is taken after unprotected intercourse. With this regimen being less effective, and causing more side effects, than the more recently introduced progesterone-only method, specific products are being withdrawn (Preven (United States, Schering PC4 (United Kingdom) and Tetragynon (France). The progesterone-only method uses the progesterone levonorgestrel in a dose of 1.5 mg, either as two 750 microgram doses 12 hours apart, or more recently, as a single dose. This method is now known to be more effective (up to 89 percent) and better tolerated (less nausea or vomiting) than the Yupze method [1], and is available in the U.S. and Canada as Plan B, in the UK as Levonelle, and in France as NorLevo. "Dedicated products" such as Plan B and Levonelle are specifically designed and marketed as emergency contraceptive pills. It is also possible to obtain the same dosage of hormones, and therefore the same effect, by taking a number of normal Progesterone only pills. ECPs are most effective the sooner they are taken[2]. The limit of 72 hours is based on a study by the WHO[3]. A subsequent WHO study has suggested reasonable effectiveness continues for up to 120 hours (5 days)[4], however many doctors (particularly in the UK) advise alternative methods for between 72 and 120 hours. These are covered below. By the way, here's a little interesting tidbit as well: The phrase "morning-after pill" is a misnomer that is falling out of use due to the fact they are licensed for use up to 72 hours after sexual intercourse. Emergency contraception or "emergency contraceptive pills" is the phrase preferred by the medical community. Tenchusatsu
