Emergency contraception is used after unprotected intercourse or failed contraception. Two hormonal products for emergency contraception are currently available on our market – Levonorgestrel, effective up to 72 hours after unprotected intercourse, and Ulipristal, effective up to 120 hours. For both products, intake should take place as soon as possible. Their action is related to suppression of ovulation, and it is impossible to accurately determine the day of ovulation. Timely intake of the hormone gives greater reliability. Once ovulation occurs, the effect of these products disappears. Ulipristal can suppress or delay ovulation for up to two days, when the risk of pregnancy is greatest. The dosage for both products is one tablet by mouth as soon as possible after unprotected intercourse. It is important to know that emergency contraception does not protect against sexually transmitted diseases!
