You have hours remaining to take plan B®.

Please take it as soon as possible because the sooner you take it, the better it works. plan B® can help prevent pregnancy if taken within 72 hours, and preferably within 12 hours, after a contraceptive accident or unprotected sex.

It has been more than 72 hours since you had unprotected sex or a contraceptive accident.

Please contact a healthcare professional for advice.


Never say never. No one plans on having unprotected sex, but it happens to the best of us.



And remember, the sooner you take it, the more effective it is.

How does the plan B® morning-after pill work?


plan B® comes in a one-pill dose. If taken within 72 hours (3 days) and preferably within 12 hours after a contraceptive accident or unprotected sex, it can prevent pregnancy by doing one of three things:

  • Temporarily stops the release of an egg from the ovary
  • Prevents fertilization
  • Prevents a fertilized egg from attaching to the uterus

plan B® is not an abortion pill—if you take plan B®, you will not be terminating a pregnancy.
