Emergency contraception
Levonorgestrel
Before using this medication, read this card and the instruction leaflet inside the box.
Make sure you’ve told us about any allergies or medical conditions you have and any other medicines you take before you take this contraception.
If you throw up (vomit) within 3 hours of taking this tablet, get in touch as you might need another dose.
Take your dose as soon as you can after sex. Check the label on the medication box for the correct dose.
It is not effective if you take it more than 3 days (72 hours) after unprotected sex.
This pill will not work as well if you have taken an emergency contraceptive pill containing ulipristal acetate, like ellaOne, in the last 7 days, as levonorgestrel can interact with this.
Taking regular contraception
If you’re interested in a regular contraceptive method, read about your options.
You can continue to take regular contraception when taking levonorgestrel. The medications will not affect each other.
How do I know it has worked?
Emergency contraception will not work if you have already ovulated. Ovulation is hard to predict, so we recommend you take this medication and do a pregnancy test in 3 weeks.
