Objectives • By the end of this presentation, participants will be able to: • Discuss need for EC among adolescents • Describe clinical components of EC • Understand the challenges and opportunities for increasing EC use at the patient, provider, and health systems level
Adolescents Need EC • The U.S. has one of the highest teen pregnancy rate in the industrialized world. • 82% of teen pregnancies are unplanned
Teen Pregnancy Rates Worldwide, 2000 Per 1000
Female Contraceptive Use at 1st Intercourse by Year of 1st Sex 2002 National Survey of Family Growth

Human Error • Inconsistent contraceptive use • Incorrect contraceptive use • Unplanned intercourse
Method Failure: Patch • Patch off for 24 hours or more during patch-on weeks • More than two days late changing a patch • Late putting patch back on after patch-free week
Method Failure: Ring • Taken out for more than 3 hours during ring-in weeks • Same ring left in more than 5 weeks in a row • Late putting ring back after ring-out week
Method Failure: Others • Condom breaks or slips • 2 or more missed active OCPs • DMPA shot 14 or more weeks ago • Expelled IUD • 3 > = hours late taking a POP • Diaphragm or cervical cap dislodges
Brand Name Levonorgestrel ECPs • Dedicated Product: Plan B One-Step • FDA approved July 2009 • ingle tablet formulation 1.5mg of levonorgestrel • Original Plan B • Two tabs of 750 mcg levonorgestrel • Approved in 1999 • Approved for OTC 18 and older in 2006 • Both are now OTC for 17 and older

Combined Oral Contraceptives as ECPs • Yuzpe method • Combined oral contraceptive pills (OCPs) containing combined ethinyl estradiol and either norgestrel or levonorgestrel
The Copper-T Intrauterine Device • Insert within 5 days • Highly effective: Reduces risk of pregnancy by more than 99% • Rarely used for EC alone • Cannot use levonorgestrel IUD (Mirena) for EC
Clinical Components of EC • Regimens • Efficacy • Mechanism of action
How Long After the Morning After? 2002 WHO Trial of Levonorgestrel-Only EC Regimen Taken in Single Dose p=.16 Von Hertzen H, et al. Lancet 2002;360:1803-1810
Mechanism of Action of Levonorgestrel-Only EC • Disrupts normal follicular development and maturation • Results in ovulation or delayed ovulation with deficient luteal function • May also interfere w/sperm migration and function at all levels of the genital tract
Does Levonorgestrel-Only EC Prevent Implantation? • Studies in animals: Levonorgestrel administered in doses that inhibit ovulation has no post-fertilization effect
Mechanism of Action: Combined ECPs • Can inhibit or delay ovulation • Older studies have shown histologic or biochemical alterations in the endometrium. • More recent studies have found no such effects on the endometrium.
Mechanism of Action: Combined ECPs *No clinical data exist regarding these mechanisms
Side Effects & Complications:Levonorgestrel v. Yuzpe Significant at p<0.01
Challenges and Opportunities • To utilize EC, young women (under 18) must • Be aware of the option • Locate a provider • Obtain a prescription • Find the money to pay for the pills • Fill prescription at a pharmacy that has EC • Take pills at correct time
Challenges and Opportunities • Patient Level • Provider Level • Health Systems and Public Policy Level
Patient Misconceptions Create Barriers to EC Use • Beliefs that EC functions as an abortifacient • Fear that the drug would harm fetus • Confusion over fertility cycle and timing
Other Barriers • Perceived lack of confidentiality • Lack of money and/or insurance • Lack of transportation • Inability to locate a healthcare provider w/in the limited and effective timeframe • Belief that pelvic examination is mandatory • OTC exclusion of minors
Providers Can Remove Clinical Barriers to EC • No pelvic examination or pregnancy test required by ACOG or FDA • Pregnancy test prior to EC treatment is recommended only if: • Other episodes of unprotected sex occurred that cycle • LMP (last menstrual period) was not normal in duration, timing, or flow
Providers Can Facilitate Use • Providers must take into account patient’s: • Knowledge of reproductive physiology • Ability to understand the regimen • Moral perceptions of contraception • Misconceptions about the drug’s mechanism of action • Barriers that may restrict access
Facilitating Use in Practice • Train office staff on EC • Importance of timely appointments • Lack of required exam for prescriptions • OTC for patients over 18
