How does it work?
ellaOne contains ulipristal acetate, a chemical that prevents or delays you from ovulating, thus protecting you against pregnancy.
ellaOne comes as a single tablet, that can be taken up to 5 days after having unprotected sex - but the sooner the better.
If you vomit up to 3 hours after taking ellaOne, you will need to take another tablet.
Does ellaOne protect against anything other than pregnancy?
No. EllaOne will not protect you against any sexually transmitted infections, and should not be used as a regular form of contraception.
If you are worried you might have a sexually transmitted infection, you can visit our sexual health clinic for advice, tests and treatments.
If you need regular contraception, then you might consider getting a prescription for the contraceptive pill from our online clinic.
