2 The New Yorker, July 23, 1999 “Don’t get me wrong. I think the morning after pill is great. It’s just that right now my problem is lining up something for the night before.”
3 Learning Objectives • Understand the history and expanding role of emergency contraception (EC) in pregnancy prevention • Understand the differences between EC regimens and their effectiveness • Identify mechanisms for raising awareness of EC within the client population • Increase awareness of EC resources • Facilitate integration of EC into routine family planning, reproductive health, and primary care activities
4 Why Is Emergency Contraception Needed? • Around 10 million couples have sexual intercourse every night in America • Approximately 27,000 condoms break or slip • Even perfect contraceptors can and do experience contraceptive failure Source:Trussell & Kowal, 1998.
5 Current Proportion of Unintended Pregnancies United States: 49% Washington State: 55% Source:Henshaw, 1998; Schrager, 1997.
6 Definition of Unintended Pregnancy • Pregnancy that is unwanted or mistimed at conception • Does not mean unwanted births/unloved children • Does mean less opportunity to prepare: • Prepregnancy risk identification • Management of preexisting conditions • Changes in diet and vitamins • Avoidance of alcohol, toxic exposure, and smoking
7 The Institute of Medicine Recommends That the Nation Adopt a New Social Norm All pregnancies should be intended–that is, they should be consciously and clearly desired at the time of conception. Source:Institute of Medicine, 1995.

9 Awareness of Emergency Contraception is Limited • Public uninformed about the method • 11% of women know the basic facts about EC • 1% have used it • These data are supported by PATH’s local assessment, which found that most clients have not heard about EC Source: Kaiser Family Foundation, 1997

11 History of EC • mid-1960s: High-dose estrogens in use • early 1970s: Combined OCs (Yuzpe regimen) • 1997: FDA announces that combined oral contraceptives are safe and effective for use as postcoital emergency contraception • 1998: First dedicated product, Preven™, approved by FDA • 1999: Progestin-only dedicated product, Plan B™, approved by FDA Adapted from ARHP, 1999. Source: Federal Register, 1997.
12 What Is Emergency Contraception? • Emergency Contraceptive Pills (ECPs) • Often referred to as “the morning-after pill” • Birth control pill hormones taken in high dose within 3 days (72 hours) of unprotected sex • IUD Insertion • Within 5 days (120 hours) of unprotected sex • Can also be a long-term contraceptive method
13 IUDs as Emergency Contraception • 99% effective in preventing pregnancies • Can be retained for up to 10 years • Screening should follow regular IUD screening criteria plus ascertain unprotected intercourse within 5 days of seeking treatment Source: Trussell & Ellertson, 1995.
Progestin-only Reduces the risk of pregnancy by 89% Side effects Nausea (23%) Vomiting (6%) Estrogen and Progestin Reduces the risk of pregnancy by 75% Side effects Nausea (50%) Vomiting (20%) 14 Two Types of ECPs Both Methods: First dose within 72 hours after intercourse Second dose 12 hours later Source: Task Force on Postovulatory Methods of Fertility Regulation, 1998.

19 Regular Oral Contraceptives Used for Emergency Contraception • In addition to dedicated ECP products, regular birth control pills can be prescribed in special doses for emergency contraception (See table in your packet)
20 Treatment Is More Effective the Sooner It Begins Source: Lancet, 1998
21 ECP Mechanism of Action • Clinical studies have shown that ECPs can inhibit or delay ovulation • Evidence regarding endometrial alterations equivocal • Not clear that changes observed would inhibit implantation • Biologic plausibility regarding inhibition of fertilization • Thickening of cervical mucous • Alterations in tubal transport of sperm or egg Source: Swahn et al., 1996; Ling et al., 1979; Rowlands et al., 1986; Ling et al., 1983; Kubba et al., 1986; Taskin et al., 1994.
22 ECP Mechanism of Action • Timing impacts how ECPs work: • Cycle day on which intercourse occurred • Cycle day on which treatment is used • Statistical evidence suggests there must be an additional mechanism beyond delaying or preventing ovulation Source: Von Hertzen & Van Look, 1996; Trussel & Raymond,1999.
23 Medical Definition of Pregnancy • NIH, FDA, and ACOG all define pregnancy as beginning with implantation • Takes about 6 days for a fertilized egg to begin to implant • Intervention within 72 hours cannot result in abortion • ECPs are not effective if a woman is already pregnant Source: Code of Federal Regulations, 1998; Hughes, 1972.
24 Providing EC Information • For some women, clearly understanding the mechanism of action will be critical to making an informed choice about ECP use.
25 Key Points on Mechanism of Action • ECPs work through various mechanisms • ECPs will not interrupt or harm an established pregnancy • ECPs are not the same as mifepristone (RU486), which is used after pregnancy is already established
26 ECP Safety:Women’s Health • According to the World Health Organization, there are no absolute contraindications for ECPs. • ECPs are believed to have no clinically significant impact on conditions such as cardiovascular disease, angina, acute focal migraine, or severe liver disease. • However, ECPs do not protect against STDs. Source: WHO, 1996.
27 ECP Safety:Health of Fetus • ECPs do not interfere with an established pregnancy. • No evidence that ECP hormones have an adverse effect on fetal development. Source: FDA, 1997.

34 Advance Distribution or Advance-of-Need Prescribing of ECPs • ECPs are more effective when taken sooner • Advance prescription reduces access barrier • Women are not more likely to use ECPs repeatedly • Advance prescription does not decrease the use of other birth control methods Source: Glasier and Baird, 1998.
