If you’ve been in a situation where you’ve not used any contraception and have taken emergency contraception after having sex, we would advise you to take Hana on the first day of your period. If you decide to start taking it sooner you’ll need to follow this important advice: Emergency contraception that contains levonorgestrel: You can start taking Hana at the same time as the emergency contraception, but you should use additional contraception, like a condom, for the first 7 days. Emergency contraception that contains ulipristal acetate, such as EllaOne: Wait 5 days, or 120 hours, before you start taking Hana again and use other contraception, like condoms, during this time. After the 5 days, when you start taking Hana again, you’ll need to use extra contraception e.g. condoms for another 7 days. Altogether, you’ll need to use the additional contraception for 12 days after taking emergency contraception that contains ulipristal acetate.
