Can oral levonorgestrel emergency contraception be given more than once in a menstrual cycle?
Oral levonorgestrel emergency contraception can safely be given more than once in a menstrual cycle [FFPRHC, 2006b]. • However, the manufacturer advises against repeated administration because of the possibility of disturbance of the menstrual cycle [ABPI Medicines Compendium, 2004a; ABPI Medicines Compendium, 2004b]. • Unprotected sexual intercourse within 12 hours of a dose of oral levonorgestrel emergency contraception does not require further treatment with an emergency contraception [FFPRHC, 2006b]. • Repeated use will not induce abortion if the woman is already pregnant [FFPRHC, 2006b].
