The Nation’s Best-Kept
Secret: Strategies for Promoting Emergency Contraception
What if ?
|
|
|
A condom broke or slipped off, you had
sex when you didn’t expect to, you didn’t use any birth control that weekend,
you missed several pills, your diaphragm or cap slipped out of place, you
were forced to have sex . . . |
Emergency Contraceptives
|
|
|
Regular contraceptives used in a
different way |
|
Prevent pregnancy after intercourse |
|
Inhibit ovulation, fertilization, or
implantation |
|
Do not cause abortion |
Emergency Contraceptives (cont)
|
|
|
Will not interrupt or harm an
established pregnancy |
|
Are not the same as mifepristone |
|
Do not protect against sexually
transmitted infections (STIs) |
Definition of Pregnancy
|
|
|
|
NIH/FDA |
|
“Pregnancy encompasses the period of
time from confirmation of implantation until expulsion or extraction of the
fetus.” |
|
ACOG |
|
“Pregnancy is the state of a female
after conception and until termination
of the gestation.” |
|
“Conception is the implantation of the
blastocyst. It is not synonymous with fertilization; synonym: implantation.” |

Mifepristone: Prescribing
for EC
|
|
|
FDA approved as abortifacient October
2000 |
|
Can legally be prescribed off label as
EC |
|
Only available in the 200 mg dose (50
mg and 10 mg just as effective as 600 mg for EC with fewer side effects) |
|
Limited prescriber availability (FDA
prescriber agreement required) |
Emergency Contraception:
Rx by Telephone
|
|
|
|
3 questions to ask: |
|
Have you had unprotected sex or a
problem with your birth control (such as condom breakage) during the last 3
days (rule out sexual assault)? |
|
Did your last menstrual period begin
less than 4 weeks ago? |
|
Was the timing and duration of your
last menstrual period normal? |
|
If the patient responds “yes” to all 3
questions, a clinician may prescribe emergency contraception over the
telephone |
Patient Counseling for EC
|
|
|
How to take medication (give written
instructions when possible) |
|
Use of antiemetic (Rx or OTC) 1 hour
prior to first dose of Yuzpe |
|
Expected side effects
(nausea/vomiting/cramping) |
|
When to expect menses (up to 98% bleed
within 21 days of EC) |
|
If no menses after 3 weeks, rule out
pregnancy |
|
May discuss contraceptive needs, STD
protection, follow-up if EC fails |
Emergency Contraception:
Barriers
|
|
|
|
Rx or Pharmacist dispensing creates
delay |
|
Woman must: |
|
Identify the need for EC |
|
Locate a prescriber |
|
Call/visit prescriber |
|
Find a pharmacy that stocks the product
(discuss EC with pharmacist in pharmacy-access states) |
Plan BŌ: Rx Data
|
|
|
|
20,000 Rxs/month for Plan B |
|
5 Pharmacy-access states |
|
Washington, California, Alaska, New
Mexico, Hawaii |
|
Washington: only 26% of pharmacies and
23% of pharmacists participate in the access program |
|
California: only 14% of pharmacies
participate |
|
Albuquerque, NM: 89% of pharmacies did
not carry Plan B; only 47% could access within 24 h |
|
Pennsylvania: only 35% of pharmacies
could get Plan B or PREVEN within 24 h |
Advance Provision of EC
|
|
|
|
|
Glasier and Baird 1998 |
|
553 given advance supply of EC pills |
|
187 (47%) used at least once; 98%
correctly |
|
18 unintended pregnancies |
|
522 told to obtain EC pills when needed
by visiting a physician |
|
87 (27%) used at least once |
|
25 unintended pregnancies |
|
Neither group experienced adverse
events |
|
No difference in use of other
contraceptives |
Advance Provision of EC:
Teens
|
|
|
Gold, et al, 2004, prospective
randomized trial at urban, hospital-based adolescent clinic |
|
301 minority, low-income women age
15-20 years |
|
Advance provision vs. instructions on
how to get EC |
|
At 1 month, the advance Rx group
reported nearly twice as much EC use as control group (15% vs. 8%, p=0.05) |
|
Advance EC group began EC significantly
sooner (11.4 h vs. 21.8 h, p=0.005) |
|
No detrimental effects on condom or
hormonal contraceptive use/no increase in unprotected intercourse |
FDA Rejects Plan B OTC
|
|
|
Reproductive Drugs and OTC Advisory
Committees met Dec 16, 2003 |
|
Voted “Yes” to place Plan B OTC (23 to
4) |
|
Plan B is safe, effective, and easy to
use |
|
FDA sent manufacturer a Non-Approvable
Letter in May 2004 |
|
ACOG and other organizations express
dismay at the FDA’s decision, suggesting political agenda |
The Setting
|
|
|
3.0 million unintended pregnancies each
year in the United States: half (48%) of all pregnancies |
|
Half (48%) of women aged 15-44 have
ever had an unintended pregnancy |
|
Emergency contraception has the
potential to reduce unintended pregnancy significantly |
|
Emergency contraception is highly
cost-effective |
Potential Impact
Actual Impact
|
|
|
In 2000, 1.3% of women having abortions
reported using ECPs to prevent that pregnancy. |
|
35% of those using ECPs had used no
method of contraception in the month they became pregnant; 65% used ECPs for
backup contraception. |
|
Up to 51,000 abortions were averted by
use of ECPs in 2000 |
The Problem:
Why a 25-Year Delay ?
|
|
|
Companies did not market pills or IUDs
for emergency contraception in the U.S. |
|
Clinicians do not routinely counsel
women (or men) about emergency contraception |
|
Women (and men) do not know about
emergency contraception |
The Solution
|
|
|
|
Market EC |
|
marketing promotes awareness |
|
specifically packaged products are less
confusing for users and providers, and may reduce chances of incorrect
prescribing or use |
|
Change provider practices |
|
counsel women and men in advance |
|
provide ECPs in advance |
|
Educate women and men |
|
Change from Rx to over/behind the
counter |

Provider Practice: Bad News
The Clinical Bottleneck
|
|
|
Clinicians overwhelmingly think ECPs
are safe and effective, and the majority have prescribed in the last year |
|
Clinicians are waiting for women to ask
for EC |
|
|
The Clinical Bottleneck (cont)
|
|
|
|
But women do not know to ask |
|
while 76% of women have heard of
ECPs/morning-after pills |

Summary
|
|
|
Unintended pregnancy/induced abortion
are major problems in the United States |
|
Reliable and easy-to-use emergency
contraceptive methods are available (Plan B, PREVEN) |
|
The Alan Guttmacher Institute estimates
that in 2000 EC prevented 50,000 induced abortions |
|
Single dose levonorgestrel first-line
method, followed by two-dose levonorgestrel, then Yuzpe |
|
In May 2004, the FDA rejected its
scientific advisory panel’s recommendation to switch Plan B to OTC |
|
ACOG’s public education campaign,
“Every Woman, Every Visit” will continue to urge Ob/Gyns to provide advance
prescriptions for EC at every office visit |
