Intrauterine contraceptive devices and antigestagens as emergency contraception.
Although the Yuzpe regimen of emergency contraception is the one most commonly used, there are alternatives. Copper-containing intrauterine devices are very effective and can be inserted for at least 5 days after unprotected intercourse and sometimes longer. They may, however, transmit pre-existing infection into the upper genital tract and cause discomfort when being fitted. Progestogen-only emergency contraception appears, from WHO studies, to be a useful adjunct to current therapies. Mifepristone has been studied in various doses and has been shown to be very effective but is not yet commercially available. Health services should provide a full range of methods including emergency contraception by appropriately trained people in an acceptable environment.
