Emergency Contraception

“The effects on ovarian activity of delaying versus immediately restarting combined oral contraception after missing three pills and taking ulipristal acetate 30 mg” The journal Contraception recently published a study investigating timing of combined oral contraceptive pill (COC) restart after missed pills and use of ulipristal acetate emergency contraception (UPA-EC). The FSRH CEU responds to this study and advises where guidance does—and does not—change.

This statement is a response to a study published in the New England Journal of Medicine, suggests that a 52mg levonorgestrel-releasing intrauterine system (LNG-IUS) is non-inferior to a T380A copper IUD (Cu-IUD) for emergency contraception (EC).
