Emergency Contraception Pill Options
Oral Progestin:
• Plan B One-Step: 1 pill by mouth
• Plan B: 2 pills by mouth
• More effective the sooner it is taken (within 72 hours)
• Over the counter or by prescription
Progesterone receptor antagonist: Ullipristal Acetate
• Current brand name is Ella
• Maintains efficacy over 120 hours
• By prescription only
• More effective for women 155-194 pounds
Emergency Contraception Website:

Improving Contraceptive Management:
Advanced EC Prescription
Key Points:
• Recommended for all sexually active females not on LARC
• Does not increase risk taking behaviors
• Increases EC use and decreases time to EC use after
unprotected sex
• No limit to number of times a patient can use EC
• Not as effective as preventive (before sex) contraception

Improving Contraceptive Initiation:
Quick start
•Key Points:
• Opportunity to provide contraception at times of high
motivation
• No need to wait for menses to begin method
• Initiate contraception immediately regardless of LMP or
recent sex
• Use back-up method for 7 days

Dual Method Use
•What: Use of a condom plus another contraceptive
•Goal: May dramatically reduce the risk of both pregnancy
and STIs
