Is 60 Hours Too Long to Take Plan B One Step?

Dear Fuzzy,

You could take Plan B One Step now, but you would be really pushing its ability to be effective. I usually recommend to take Plan B within 12 hours of having unprotected sex; that is when Plan B will have the highest probability of being effective. Each hour you wait your probability for Plan B being effective decreases.

Best luck,
Hannah
