let me be the 3rd person (including the other thread) to point out that the drug that was legalized in Canada is levonorgestrel (better known as "Plan B", or the "morning after pill")... it is
NOT RU486 (aka Mifepristone)
you might want to read the last few lines of this web page... if I'm reading it correctly, it's currently available without a prescription in 6 states.
http://www.go2planb.com/...ion/about/index.html Is Plan B safe? When used as directed, Plan B is safe for most women. There have been no serious complications associated with Plan B. Common side effects include nausea, abdominal pain, fatigue, headache, and menstrual changes. Women who are pregnant, have undiagnosed vaginal bleeding, or have an allergy to the product should not use Plan B.
Plan B cannot terminate an established pregnancy. How effective is Plan B? Taken within 72 hours of unprotected intercourse, Plan B can, when used correctly, reduce the risk of pregnancy by 89 percent after a single act of unprotected sex. Effectiveness declines as the interval between intercourse and the start of treatment increases.
Dosage and administration? Each Plan B packet includes a single course of treatment and consists of two tablets; each tablet contains 0.75 mg levonorgestrel. The first tablet should be taken orally as soon as possible within 72 hours (three days) of unprotected intercourse. The second tablet must be taken 12 hours later. Plan B is not a substitute for routine methods of birth control. Plan B does not provide protection from HIV (the virus that causes AIDS) and other sexually transmitted infections.
How important is the timing of treatment to efficacy? The sooner Plan B is taken after unprotected intercourse, the more effective it is. Effectiveness of Plan B declines as the interval between intercourse and the start of treatment increases. The decline in efficacy from a delay in treatment is why a broad range of health professionals believe that barriers to more timely access to Plan B should be removed, including making the product broadly available without prescription.
How does Plan B work (mechanism of action)? Plan B is believed to act as an emergency contraceptive principally by preventing ovulation or fertilization (by altering tubal transport of sperm and/or ova). In addition, it may inhibit implantation by altering the endometrium. Plan B is not effective if a woman is pregnant. Plan B is a contraceptive and cannot terminate an established pregnancy.
Will Plan B harm an unborn fetus? There is no evidence that Plan B would harm a pregnant woman or a developing fetus if the product were accidentally taken during early pregnancy. Studies involving women who have inadvertently taken combined oral contraceptives containing levonorgestrel during early pregnancy suggest that these drugs do not have an adverse effect on the fetus.
Is Plan B the same as RU486 (abortion pill)? No, Plan B is not an abortifacient. It is an emergency contraceptive and should not be confused with RU486 or any other abortifacient. Plan B is not effective if a woman is pregnant.
Can pharmacists provide Plan B without a prescription? Plan B is currently available by prescription only.
However, emergency contraception is currently available in a limited number of pharmacies in six U.S. states (Alaska, California, Hawaii, Maine, New Mexico, and Washington State) without an advance prescription from a physician.
