EllaOne is currently the most effective emergency contraceptive product on the market with a 95% success rate even if it is taken up to 120 hours (5 days) after unprotected sex.
EllaOne contains the active ingredient Ulipristal Acetate which prevents or delays ovulation by acting on the receptors for progesterone (the female sex hormone) and preventing the egg from becoming fertilised and hence protecting from pregnancy.
It will not prevent pregnancy if you have had unprotected sex after you have taken it or if you take it after you have ovulated.
Although 95% effective, EllaOne will not completely guarantee you from pregnancy and therefore should not be used as a substitute for regular contraception. If you are engaging in unprotected sex on a regular basis, then you can look at our Contraceptive Pill treatment.
ellaOne will not protect you from sexually transmitted infections (STIs).
