Emergency Hormonal Contraception (EHC)

About this treatment

Hormonal EC (Emergency Contraception) pills, also known as the "morning after pill," are hormonal medications taken after unprotected sex or contraception failure to prevent pregnancy by delaying or preventing ovulation. There are two main types: levonorgestrel (e.g., Levonelle), which is effective for up to 72 hours (3 days) after sex, and ulipristal acetate (e.g., ellaOne), which is effective for up to 120 hours (5 days). The sooner the pill is taken, the more effective it is, and ulipristal acetate is considered more effective overall.
