[When is the morning-after pill indicated and which application is preferable?].


 Several questions are posed concerning the optimal time for use of the morning- after pill. In general the rule of thumb is that the pill should be used no earlier than 12 hours before unprotected intercourse, not more than 72 hours afterwards (ideally between 12 and 48 hours after intercourse). Another question concerns the issue of whether the instructions for the 2x2 and the 5x5 methods could be identical. With regard to the situation of forgetting to take the pill, the timeliness or lateness of taking a morning-after pill is explored in relationship to the time of coitus. The last question examines whether the effectiveness of the 5x5 method is identical when it is taken in a regimen of 1 mg 5 times per day to when it is taken in a regimen of 5 mg once a day. The 2x2 method is popular, but increasingly information is also available exclusively about the 5x5 method. The crucial question before buying a suboptimal postcoital contraceptive is whether a dominant follicle could possibly develop. A pause in pill use of 7 days hardly gives the follicle the chance to grow into a dominant follicle. Therefore, the use of pills in principle is a reliable method of contraception. The most available method for the prevention of implantation of the blastocyst is the application of an IUD. According to the literature on the subject, the morning-after IUD is particularly reliable up to 5 days after ovulation. Very high-dose ethinyl estradiol (1 mg 5 times per day for 5 days) is another method; it has a 95% effectiveness rate if taken within 36 hours (and, at the latest, 48 hours) after coitus.
