What is Plan B™?
Plan B™ is an emergency contraceptive that can prevent pregnancy from occurring after an act of sexual intercourse. It can be taken within 120 hours (5 days*) of unprotected intercourse or a birth control mishap (missed pills, condom breakage, etc.). The sooner Plan B is taken, the more effective it is.
- When Plan B is taken within 24 hours it is 95% effective.
- When Plan B is taken within 24-48 hours it is 85% effective.
- When Plan B is taken within 49-72 hours it is 58% effective.
*Plan B can be taken for up to 120 hours (5 days), however it is recommended to be taken sooner as it is less than 50% effective after 3 days.
How does Plan B™ work?
Plan B™ contains a hormone called levonorgestrel. When taken, Plan B™ can stop or delay ovulation from occurring. If an egg has already been released, it can prevent a fertilized egg from implanting itself in the uterus. Plan B will not end or harm a pregnancy that has already occurred.
