The first drugs used for emergency contraception were developed in the 60`s. However, they had many side effects, so their use was reduced to a minimum.
A combination of drugs came to replace estrogen-based drugs. Canadian doctor Albert Yuzle was the first to use and promote this method of emergency contraception. According to some data, the effectiveness of this method is about 97%, however, one third of women also complain of side effects.
Since 1993, the most popular means of emergency contraception are drugs based on levonorgestrel (“Escapel”,”Postinor”). They prevent ovulation, and if fertilization has already occurred, interfere with the implantation of the egg. Unfortunately, this method is not as safe as we would like. Nausea, often accompanied by vomiting, is observed in a quarter of women who use this method of emergency contraception. In addition, these tablets significantly change the hormonal background, resulting in a woman may experience acyclic bleeding.
The modern effective drug for interrupting an unwanted pregnancy in the early stages is Mifegin (mifepristone). With his help, a medical abortion is often performed. If the pill is taken within 72 hours of unprotected intercourse, there is a high probability that the pregnancy will not occur. The medicine is sold strictly by prescription, and the dosage and the intake schedule are determined individually depending on the weight and health status of the patient.
An intrauterine device can be used as an emergency contraceptive. This method is especially good for those women who are going to be protected so in the future. The introduction of the spiral should be made no later than 5-7 days after unprotected contact. Some women of the IUD are contraindicated, it is only the specialist who can make a decision about the admissibility of using this tool in your case.
Often, women resort to syringing with various solutions after unprotected intercourse. This method is extremely ineffective and can not be considered a reliable emergency contraceptive.
It should be noted that all methods of postcoital contraception are unsafe, and therefore should not be used more than twice a year.
