Emergency Contraception (Emergency Contraception, Ec)

Emergency contraception frequently used are insertion of a copper IUD (T380A) within 5 days after unprotected sexual intercourse levonorgestrel (0.75 mg po) in 2 doses 12 hours apart within 120 hours after the unprotected intercourse levonorgestrel (1.5 mg po ) once within 120 hours after the unprotected intercourse ulipristal acetate (30 mg po) once within 120 hours after the unprotected intercourse women with regular menses, are at risk of a pregnancy after a single sex of about 5%. This risk is 20-30% when sexual intercourse takes place in the middle of the cycle. When a copper IUD is used as emergency contraception, it must be used according to the presumed ovulation within 5 days after unprotected sexual intercourse or within 7 days. The pregnancy rate for these emergency contraception is 0.1%. Also, the IUD can be left for permanent contraception in situ. In the emergency contraception, the copper-containing IUD affects the implantation of the blastocyst; but it seems not to interrupt an existing pregnancy. The emergency contraception containing levonorgestrel prevents pregnancy by inhibiting or delaying ovulation. The probability of pregnancy is reduced to emergency contraception with levonorgestrel by 85%, which corresponds to a pregnancy rate of 2-3%. However, the reduction of the risk of the following factors depends on: Risk of women for getting pregnant without emergency contraception at the time in the menstrual cycle, is added to the given emergency contraception BMI of the woman (in obese women with a body mass index [BMI]> 30 is the emergency contraception containing levonorgestrel less effective than with ulipristal acetate) Under ulipristal acetate (a progestin receptor modulator), the pregnancy rate about 1.5%; it is therefore more effective than levonorgestrel. Ulipristal acetate, such as levonorgestrel, prevents pregnancy mainly by delaying or inhibiting ovulation. Although ulipristal acetate is more effective than levonorgestrel in women with a BMI> 30, takes his effectiveness with increasing BMI. Therefore, a copper-containing IUD is in overweight women who want to absolutely avoid an unwanted pregnancy, the preferred method of emergency contraception. There are no absolute contraindications for emergency contraception with levonorgestrel or Ulipristal acetate. A levonorgestrel Notfallkontrazeptiv can be purchased at a pharmacy without a prescription. Ulipristal acetate is available only by prescription. Levonorgestrel- and ulipristal Notfallkontrazeptiva should be taken as soon as possible and within 120 hours after unprotected sexual intercourse. A further Regim (the Yuzpe method) consists of 2 tablets, each containing 50 ug of ethinyl estradiol and 0.25 mg of levonorgestrel, followed by further 2 tablets after 12 hours, but within 72 hours of unprotected intercourse. The high amount of estrogen often causes nausea and vomiting. As this Regim is less effective than other methods, it is applied only in women who are not available to those other methods. A Notfallkontrazeptiv can be given if another hormonal contraceptive is given as part of a “Quick Start Protocol”. It is recommended to perform a urine pregnancy test two 2 weeks after the emergency contraception. Summary normally be used hormones (eg ulipristal acetate, levonorgestrel.) For emergency contraception (EC); they be taken as soon as possible within 120 hours after unprotected sexual intercourse. A copper IUD, which is used within 5 days after unprotected intercourse is also effective and can be left in situ for permanent contraception. The pregnancy rates are 1.5% with ulipristal acetate, 2-3% with levonorgestrel and 0.1%, with a copper-containing IUD. The chances of pregnancy by hormonal emergency contraception depends on the risk of pregnancy without emergency contraception, from the time in the menstrual cycle when the Notfallkontrazeptiv is taken, and the BMI of the woman from.
