See below: Levonorgestrel(Plan B) is not 100% effective in preventing pregnancy. If taken within 72 hours it will reduce the chance of pregnancy by 50%. It is somewhat less effective after 72 hours. You can take a repeat dose at day 5 although not approved for same. The copper IUD is the most effective emergency contraceptive.
