If intercourse took place without additional protection, there is a risk of pregnancy. The use of ellaOne emergency contraception is most effective within the first 24 hours after improperly secured intercourse. You may use emergency contraception to reduce the risk of pregnancy. After using ellaOne, you will need to use additional contraception, e.g. in the form of condoms, until you start a new pack of Drovelis. After taking the emergency contraceptive tablet, take the next Drovelis tablets at the same time each day. For a prescription for ellaOne, consult your doctor.
