EllaOne Hero

What is EllaOne?

EllaOne® is an oral emergency contraceptive pill (or ‘morning after pill’). It can be taken following unprotected sex, or the failure of your regular contraceptive method to reduce the risk of an unplanned pregnancy. It should be taken as soon as possible – within (at most) 5 days (120 hours) after having unprotected sex to be the most effective.


How does EllaOne work?

After unprotected sex, sperm travels up the fallopian tubes where they wait for an egg to be released. Since sperm has a maximum lifespan of five days, EllaOne® prevents or delays ovulation until all the sperm have died.

It is essential that you take EllaOne® as soon as possible after having unprotected sex in order to maximise its effectiveness.

EllaOne is available at your local pharmacy.
