Emergency Birth Control FAQs
What is Emergency
Birth Control (EBC)?
Emergency birth control (EBC) is a safe
and effective method of preventing pregnancy following unprotected
sexual intercourse. EBC initiated within 72 hours of unprotected
sexual intercourse reduces the chance of pregnancy by 89%, decreasing
the random chance of pregnancy from 8% to 1% after a single act
of unprotected sexual intercourse. It works with the hormones in
your body by interfering with fertilization and implantation of
the egg.

Can I still get pregnant?
Yes. EBC significantly reduces the chance
you will get pregnant, but it does not eliminate the possibility.
By taking EBC you may be at increased risk of ectopic (tubal) pregnancy,
which causes severe abdominal pain and can be life-threatening.
You should call Feminist Women's Health Center immediately if you
have severe abdominal pain and you should return to Feminist Women's
Health Center for a urine pregnancy test (it’s free!) in 3
weeks if you have not had a menstrual period since taking EBC.

How soon can I take it?
EBC is commonly known as the “morning-after
pill,” but that term is misleading; EBC may be taken sooner
than the morning after -- immediately after unprotected intercourse
-- or later -- for up to 5 days (120 hours) after unprotected intercourse.
Use of EBC within 3 days (72 hours) of unprotected intercourse is
the best way to ensure that you do not get pregnant. More recent
studies indicate that the pills continue to be moderately effective
if started between 72 and 120 hours of unprotected intercourse.

What is Plan B®?
The FDA has approved one dedicated emergency
contraception product, Plan B®
which is available at pharmacies and clinics in a 2-pill package.
The pills contain hormones that work in your body to stop the egg
from being fertilized and/or implanted. The FDA has stated that
several brands of Norgestrel or Levonorgestrel containing combined
oral contraceptives (OC) are safe and effective for use as EBC as
well (see the chart below).
top of page
Is EBC safe?
There have been no reports of long or short-term
health risks associated with EBC use. EBC will not end a pregnancy
that has already started and no significant effects on fetal development
have been reported or linked with women who take EBC. Therefore,
pregnancy is a contraindication to EBC use not because of the risk
of fetal harm, but because it will not work in the event of a pre-existing
pregnancy.

What are the side effects?
The most common side effect is nausea.
Plan B ® (because it is Levonorgestrel-only) is not likely to
cause nausea; nausea and vomiting is much more common with the estrogen
and progestin combined pills. To reduce the risk of vomiting the
pills, you should have something to eat before taking the pills
and you may want to take an over the counter anti-nausea medication
(such as Dramamine) before you take the EBC pills.
Repeat dose if either pill is vomited
within 1 hour of swallowing,
Side effects vary widely from woman to
woman, are similar to pre-menstrual type symptoms and depend largely
on where you are in your menstrual cycle when the EBC is taken.
Some women will experience irregular bleeding or spotting, breast
tenderness, cramping, dizziness, headache, backache and a menstrual
period that is either a few days early or a few days late. Please
call if you have any questions about whether a side effect is normal.
There are other more serious side effects
associated with the estrogen and progestin combined method of EBC
(Yuzpe method). These side effects are the same ones associated
with birth control pills (blood clots, stroke, allergic reaction,
etc). All women with: undiagnosed vaginal bleeding, migraines, high
blood pressure, blood clots, cardiac disease or liver disease should
be screened and carefully evaluated by a licensed health care provider
prior to being given any form of medication.

What else should I know?
- You may resume use of your normal birth control
method immediately; you should use it consistently until your
menstrual period resumes.
- You are not protected from pregnancy if repeated
acts of unprotected intercourse occur after EBC use. You will
need to take another dose of EBC to protect yourself in the event
of a separate contraceptive failure.
- Repeated use of EBC is not as effective in
preventing pregnancies as many other contraceptive methods so
ask a health educator about a more reliable contraceptive method
if you need one.
- Either call or return to the Feminist Women's
Health Center immediately if abdominal pain or abnormal bleeding
occurs within a month of taking EBC. It is necessary to rule out
ectopic pregnancy and you must seek emergency care immediately
if such a pregnancy is suspected.
- Call or return to the Feminist Women's Health
Center clinic in 3 weeks if your period has not started. In 75-85%
of cases, menses onset after EBC is within seven days of when
normally expected.

How do I take EBC?
- Plan B®
( Levonorgestrel-only method) – Take both pills at the same
time, or in a divided dose 12 hours apart for a total treatment
dose of 1.5mg levonorgestrel. The package inserts says to take
the pills 12 hours apart, but new studies show that it is slightly
more effective when both pills are taken at the same time.
- Yuzpe method –combination oral contraceptives
containing a total treatment dose of at least 200 mcg of ethinyl
estradiol and 1mg levonorgestrel or 2mg norgestrel. The FDA has
stated that the following combined oral contraceptives are safe
and effective for use as EBC: Ovral, Lo-Ovral, Nordette, Levlen,
Levora, Triphasil, Tri-Levlen, Trivora, Alesse, and Levlite. Taken
in 2 doses 12 hours apart, and initiated within 72 hours of unprotected
sexual intercourse, use of the Yuzpe method reduces the chance
of pregnancy by 75%, decreasing the rate of pregnancy from 8%
to 2% after a single act of unprotected sexual intercourse.
