You have to take Levonelle One Step® emergency contraceptive pills within 72 hours of having unprotected sex and preferably within 24 hours to be most effective.
The effectiveness of Levonelle One Step® depends on how many hours have passed since you had unprotected sex.
- Within 24 hrs - 95%
- Between 25-48 hrs - 85%
- Between 49-72 hrs - 58%
If you're worried about the possibility of an unplanned pregnancy, it's important to act now rather than waiting till later.
