Levonelle is a popular morning-after pill, used to prevent pregnancy for up to three days after unprotected sex or when contraceptive methods have failed.
It is most effective when taken immediately after intercourse. Taken as a single dose, Levonelle contains 1500mcg of the active ingredient levonorgestrel.
If taken within the first 24 hours after unprotected sex, this medication is 95% effective at preventing pregnancy.
Please note – you must order before 4:30 pm (Monday – Friday, excluding bank holidays) to receive next-day delivery. The sooner you take the morning-after pill, the more effective it will be.
How long do I have to take Levonelle?

Can Levonelle protect against STIs?
Please note, Levonelle will not protect you against sexually transmitted infections (STIs). Only barrier protection (condoms) will do this.
If you have had unprotected sex and are worried you might have contracted an STI, you should take a test and contact your GP or local GUM clinic.
