Emergency contraception (ECPs) can prevent pregnancy if taken after unprotected sex. There are three main types of ECPs: 1. Progestin-only pills containing levonorgestrel (Plan B) work best if taken within 72 hours after sex and are 75% effective. 2. Ulipristal acetate (ELLA) can be taken within 120 hours of sex and has a 60% effectiveness rate. 3. An intrauterine device (IUD) inserted within a week of sex is over 99.9% effective and is the most effective emergency contraception option.

3. ECPs
• Emergency contraception (EC), or
emergency postcoital
contraception, are birth control
measures that, if taken after
sexual intercourse, may prevent
pregnancy.

4. ECPs
• Primary contraceptives >>> ordinary
contraceptive methods
- Oral C P.
- Depo-Provera
- IUD
• Secondary contraceptives >>> emergency
contraceptive methods

5. General concepts :
• Taken after unprotected sexual intercourse or
barrier contraceptive failure.
• contain higher doses of the same hormones
(estrogens, progestins, or both) found in
regular combined oral contraceptive pills.
• ECPs are most effective when used shortly
after intercourse.
• i.e should be taken within 72 – 120 hr after
the intercourse.

6. General concepts :
• combined contraceptives is shown to be less
effective and less tolerated than the
progestin-only method.
• Emergency contraceptive pills (ECPs) are not
to be confused with mifepristone and
Misoprostol , which are used as an "abortion
pills“.

7. Types of ECPs
(1) The progestin-only method uses the
progestin levonorgestrel :
 called : plan B
 in a dose of 1.5 mg.
 either as two 750 μg doses 12 hours apart, or
more recently as a single dose.
 to be taken within 72 hr.
 75 % effective.

8. 
 Note : the strength of levonorgestril in
minipills is usually 30 micgm..and in combined
pills is 150 micgm.
Thus : taking 10 tabs from combined pills that
containing 150 micgm will be equal to 1500
micgm = 1.5 mg = plan b single ECPs.

10. (2) Ulipristal acetate :
was approved as an ECP in Europe in early
2009 and in the US in August 2010.
 called : ELLA
 in dose 30 mg.
 It works for up to 120 hours after intercourse.
 is in the class of progestin's.
 It has shown to prevent about 60% of
expected pregnancies.

12. (3) Intrauterine device (IUD) for
emergency contraception :
 Insertion of an IUD is more effective than use
of Emergency Contraceptive Pills.
 99.9 % effective if used within week after
intercourse.
