Escapelle contains levonorgestrel, which prevents ovulation and fertilization. A pill taken early enough up to 72 hours after unprotected intercourse prevents pregnancy in 84%.
Available sources state that levonorgestrel can delay the onset of ovulation for up to 5 days. It should be remembered that this is an estimated number of days, each body may react differently to the substance taken.

I encourage you to read the threads about the Escapelle preparation:
