Emergency Contraception: What You Need to Know

by OB/GYN | Dec 15, 2024 | Women's Health

Emergency contraception (EC) is a safe and effective way to prevent pregnancy after unprotected intercourse or contraceptive failure. At Cary OB/GYN in North Carolina, we understand the importance of providing accurate and timely information about emergency contraception so you can make informed decisions about your reproductive health.

Emergency contraception is not meant to replace regular birth control but can be a crucial option in specific situations, such as:

  • Unprotected sex
  • Condom breakage or slippage
  • Missed birth control pills
  • Sexual assault

Types of Emergency Contraception

There are two main types of emergency contraception available:

  1. Emergency Contraceptive Pills (ECPs)
    • Levonorgestrel-based pills: These over-the-counter pills, like Plan B One-Step, are most effective when taken within 72 hours of unprotected intercourse. They work by delaying ovulation, preventing the release of an egg.
    • Ulipristal acetate pills (Ella): Available by prescription, these are effective for up to 5 days after unprotected intercourse. Ulipristal acetate works by inhibiting or delaying ovulation and is considered more effective than levonorgestrel pills, especially later in the 5-day window.
  2. Copper IUD (Paragard)
    • The copper intrauterine device (IUD) is the most effective form of emergency contraception. When inserted by a healthcare provider within 5 days of unprotected intercourse, it can prevent pregnancy by interfering with sperm movement and fertilization. The copper IUD also provides ongoing birth control for up to 10 years.

How Effective Is Emergency Contraception?

The effectiveness of emergency contraception depends on the method used and how quickly it is taken after unprotected intercourse.

  • Levonorgestrel pills reduce the risk of pregnancy by 75-89% when taken within 72 hours.
  • Ulipristal acetate is about 85% effective, even when taken up to 5 days later.
  • The copper IUD is over 99% effective.

Important Considerations

  • Timing is crucial: The sooner you use it, the more effective it will be.
  • Body weight can impact effectiveness: For individuals with a higher body weight, Plan B may be less effective. Consider using ulipristal acetate or a copper IUD in these cases.
  • Not an abortion pill: Emergency contraception does not terminate an existing pregnancy; it works to prevent pregnancy from occurring.
  • Side effects: Temporary side effects may include nausea, headache, or changes in your next menstrual cycle.
