Emergency contraception can prevent most pregnancies when taken after intercourse. It provides an important back-up in cases of unprotected intercourse or contraceptive accident (such as forgotten pills or torn condoms), and is especially valuable after rape or coerced sex. This fact sheet refers to levonorgestrel-alone emergency contraception pills (LNG ECPs), which are available in most countries.
