What is the difference between the two pills After?
The morning-after pill is available with two different active ingredients: Ulipristal acetate and levonorgestrel – both work by postponing ovulation. However, they differ in terms of their effective window.
The morning-after pill with the active ingredient ulipristal acetate can still be taken up to 120 hours – i.e. 5 days – after the contraceptive breakdown. The alternative with the active ingredient levonorgestrel can work up to a maximum of 72 hours (3 days) after the breakdown. Remember: the sooner you take the morning-after pill, the safer it protects you from an unwanted pregnancy1.
