The recommended methods of EC that are in common use include the copper-bearing intrauterine device (Cu-IUD) and the oral drugs levonorgestrel (LNG) and ulipristal acetate (UPA). This review presents the available methods of EC, effectiveness of EC, impact on abortion rates, and strategies that might increase the population impact of EC.
Oral EC is so safe and well tolerated that it should not require a prescription.
Oral EC is only effective if ovulation has not yet occurred.
The copper-bearing IUD is much more effective than oral EC, as it can prevent both fertilisation and implantation.
In women with obesity, UPA is a more effective oral EC than LNG.
It is important to commence effective regular contraception after EC.
Hormonal contraception can be started immediately after LNG or five days after UPA.
