Emergency Contraception

You get caught up in the heat of the moment, and have sex without contraception. Maybe the condom breaks, you forgot to take your regular birth control, or worst case, you were sexually assaulted.  Regardless how it happens, unprotected sex can cause an unplanned pregnancy. This can be a scary experience, but ESTPH can help with something called emergency contraception (EC).

What is it?

  • EC are pills that women can take to prevent a pregnancy from happening
  • ESTPH stocks a brand of EC called Plan B
  • Plan B is two pills that contain a synthetic hormone called Levonorgestrel
  • Plan B is not an abortion pill
  • Plan B can be used up to 5 days after unprotected sex, but the sooner it is taken the more effective it is
    • 95% effective if taken within the first 24 hours after sex
    • 85% effective if taken 25-48 hours after sex
    • 58% effective if taken 49-72 hours after sex
    • Less than 58% effective if taken between 72-120 hours after sex
    • Effectiveness of ECP is decreased if a woman is over 165 pounds

Where can I get it?


Go to the nearest pharmacy where you can acquire it without a prescription (prices vary). 

Elgin St. Thomas Public Health

Women requiring Plan B can come to the sexual health drop in clinic  to speak with a nurse. Unfortunately, the nurse cannot give these pills to anyone other than the woman who requires them. 

Cost of the Plan B at the Health Unit is $12 (cash/debit).
