ABSTRACT
PIP: There are several contraceptive methods that can be used to prevent pregnancy after unprotected intercourse. US women rarely use them, however. Nurse-midwives should become familiar with postcoital contraceptive methods and consider providing them through their practice. The most common postcoital contraceptive method in the US is the Yuzpe regimen. The IUD can be been used but its high cost and restrictions to multiparous, monogamous women at low risk of sexually transmitted diseases limit its use as a postcoital contraceptive method. The Yuzpe regimen includes two doses of two oral contraceptive (OC) pills, each containing 50 mcg ethinyl estradiol and 0.5 mg norgestrel. Its failure rates range from 0.2% to 1.9%. No serious or long-term complications have been reported. Two common side effects are nausea and vomiting. Possible modes of action of the Yuzpe regimen are: blockage of the midcycle luteinizing hormone surge, alteration of corpus luteum function, or alteration of the endometrium resulting in implantation suppression. Two possible new drugs for postcoital contraception are mifepristone (RU-486) and danazol, a synthetic hormone resembling testosterone. Possible reasons why postcoital contraception is not used more widely include: lack of information about it among women and health care providers; lack of approval by the US Food and Drug Administration, which prohibits OC manufacturers from advertising the OC for postcoital use, and federally funded family planning services cannot use drugs for non-approved indications; adverse social attitudes toward sexuality and abortion; the fact that it is considered an early form of abortion; and limited evidence of its actual effectiveness. Nurse-midwives could follow a conservative approach when prescribing the Yuzpe regimen; for example, its use should only be voluntary and based on a woman's certainty she does not want to become pregnant.
