Ulipristal Acetate mimics and blocks progestin, thereby delaying ovulation; it can be used for emergency contraception up to 5 days after unprotected sex.
Clinicians should counsel patients that starting hormonal contraception immediately after taking ulipristal acetate may make both medications less effective.
