You can have sex after taking ellaOne®, but you should use a condom if you’re not trying to get pregnant. One dose of ellaOne® is only effective for one incident of unprotected sex, it will not protect you against anything in the future.

ellaOne® delays ovulation for 5 days which is the same as a sperm’s lifespan, so any sperm that enter the female reproductive system after taking ellaOne®, they may still be alive – and able to fertilise an egg – by the time ellaOne® is no longer effective.

If you have taken ellaOne® because of an accident with regular hormonal contraception – like missing a pill – it is still recommended to use a condom until your next period arrives, as your regular contraception may be less effective.
