Levonorgestrel is the generic version of Levonelle (Plan B). Levonelle contains the same active ingredient levonorgestrel and works the same way. Levonorgestrel is also used in other forms of birth control, like combined pills, mini-pills and IUDs. These can’t be used as emergency contraception but are helpful for long-term protection from unwanted pregnancies.
EllaOne is the other option and it’s unique in that it’s the only emergency birth control that uses the active ingredient ulipristal acetate, and can be taken up to five days after unprotected sex.
