Does taking plan b within the 72 hours completely elimate the chance of getting pregnant?
3 doctors weighed in across 2 answers
No: No matter the medical condition, no treatments are 100% effective. Taken per directions, Plan B is about 90-95% effective in preventing pregnancy. Taken within 72 hours, it's close to 90% effective and within 24 hours, it's about 95% effective.

No - nothing is 100%: Plan B One-Step is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex. It can reduce chance of pregnancy by up to 95% if used within 24 hours. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes.
