There exist two methods of emergency contraception:

• installation of a Coil (or Intra-uterine Device) in the five days which follow the sexual relation at the risk.
• the catch of tablets intended for emergency contraception (or " pill of the lendemain") in the five days after the taking risk.

Most accessible is the pill of the following day , or pill for emergency contraception . The Femme can take it in the three days (even five) after the Sexual relations to prevent a possible Grossesse.

It acts by delaying the Ovulation if this one did not take place yet, or by preventing the Fécondation while acting on the mobility of the spermatozoa by effect on the cervical glaire. It was shown that it does not have an action on the Endomètre and that it does not cause an abortion, because it is ineffective once the Nidation started.

The pill of the following day differently acts from abortive pills the such Mifépristone (Mifégyne®) (historically known under the name of RU486).

Types of pill of the following day

Hormonal contraception urgently is available in two principal forms:

• the original version (known as method of Yuzpe) implies high amounts of estrogen S and progestatif in two amounts at 12 hours of interval Estrogen and Progesterone taken ace two amounts At 12 hour intervals. Technical This is believed to Be approximately 75% effective when taken within 24 hours off unprotected free intercourse. Contraceptive Examples off Yuzpe Regimen emergency pills include Preven (the USA), Schering PC4 (the U.K.) and Tetragynon (France). Severe This regimen is known to Be associated with side effects, especially nausea and vomiting, and has largely been superceded by the progesterone-only method. -->

• the method with progestatif only uses an amount of 1,5 Mg of progestatif, the Lévonorgestrel. This drug is available in credits since 2007. This method is known to be more effective (more than 95% if it is taken in time), surer and tolerated better by the organization than the Yupze method, and is available to the the United States and the Canada under name plane B and in Great Britain under the name of Levonelle .

Preven , Norlevo , Plane B and Levonelle are specifically designed and marketed ace emergency contraceptive pills. Possible It is also to obtain the same proportioning off hormones, and therefore the same effect, by taking has off number normal birth control pill S; see Yuzpe Regimen for nap examples. Note: Preven is No to skirt in production intense ace it is less effective and has more side effects than other emergency contraceptive pills. -->

Limits of the pill of the following day

Several studies show that a catch in the 12 hours following the sexual relation not protected removes almost any risk of pregnancy (95% of effectiveness). It would seem that its effectiveness falls to nearly 80% if it is taken in the 72 hours, to 60% between 72 and 120 hours.

The pill of the following day is not on the other hand of any utility if it is taken after the establishment of egg, it is thus appropriate not to exceed the time indicated.

Medical counter-indications

• Over-sensitiveness with the levonorgestrel or one of the Excipients.

Several catches during same a menstrual Cycle can cause important disturbances of the cycle or abnormal bleedings but without gravity.

This pill should not be regarded a means of contraception usual or even occasional, but only as one emergency possibility.

The doctors note that certain people not having regular reports/ratios use this pill like means of contraception, because it is easier to take a pill than to follow a regular contraceptive treatment (contraceptive Pilule) or to use a Préservatif. However, it is important to consider that the pill of the following day is less effective long-term than a regular contraception.
