OBJECTIVES: This study examined the cost-effectiveness of emergencycontraceptive pills, minipills, and the copper-T intrauterinedevice (IUD) as emergency contraception. METHODS: Cost savingswere modeled for both (1) a single contraceptive treatment followingunprotected intercourse and (2) emergency contraceptive pillsprovided in advance. RESULTS: In a managed care (public payer)setting, a single treatment of emergency contraception afterunprotected intercourse saves $142 ($54) with emergency contraceptivepills and $119 ($29) with minipills. The copper-T IUD is notcost-effective as an emergency contraceptive alone, but savingsquickly accrue as use continues. Advance provision of emergencycontraceptive pills to women using barrier contraceptives, spermicides,withdrawal, or periodic abstinence saves from $263 to $498 ($99to $205) annually. CONCLUSIONS: Emergency contraception is cost-effectivewhether provided when the emergency arises or in advance tobe used as needed. Greater use of emergency contraception couldreduce the considerable medical and social costs of unintendedpregnancies.
