Emergency contraception. Fact sheet.
Emergency contraception can prevent most pregnancies when taken after intercourse. Emergency contraception can be used in the following situations: unprotected intercourse, contraceptive failure, incorrect use of contraceptives, or in cases of sexual assault. There are 3 methods of emergency contraception: emergency contraceptive pills (ECPs), combined oral contraceptive pills or the Yuzpe method, and copper-bearing intrauterine devices (IUDs). A copper-bearing IUD is the most effective form of emergency contraception available when inserted within 5 days of unprotected intercourse. The emergency contraceptive pill regimen recommended by WHO is either: a. 1 dose of levonorgestrel 1.5 mg, or 1 dose of ulipristal 30 mg, taken within 5 days (120 hours) of unprotected intercourse; or b. 2 doses of combined oral contraceptive pills (also known as the Yuzpe regimen).
