懷孕後誤服緊急避孕藥
醫生您好,我在事先不知自己已經懷孕約半個月的情況下,和先生房事後服食了名為左決諾孕酮片的緊急避孕藥。想請問下這個藥對胎兒是否有害,會不會導致胎兒畸形?大陸這邊的醫生讓我自己看說明書自己決定要不要繼續妊娠。我實在不知道怎麽辦,也不懂這些專業知識,懇請幫我解答壹下,謝謝了。

Hello Daisy,
I think you have used levonorgestrel pills as emergency contraception.
There is very limited information specifically on emergency contraception EC use during pregnancy since it is taken for the prevention of pregnancy, requires only two doses, and will not interrupt an existing pregnancy. A review of the literature on inadvertent use of oral contraceptives OC during pregnancy provides the most information relevant to fetal exposure to sex hormones in early pregnancy. The doses of sex hormones in EC pills are about 2-5 times that that of OC pills containing the same hormones. There are many reported cases of women inadvertently taking OCs, either combination hormonal pills containing an estrogen and a progestin, or progestin-only pills (POPs), for up to several months while pregnant. Comprehensive reviews showed exposure to sex hormones [both combination hormonal products and levonorgestrel-alone pills] in early pregnancy DOES NOT have a teratogenic effect.
