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