Progestin for Emergency Contraception
Emergency contraception effectiveness varies according to the method used.
- Emergency contraception, such as Plan B, can prevent nearly 75% of pregnancies.1
- Plan B is more effective when used for emergency contraception than combined birth control pills (estrogen and progestin).
The sooner pills are used after unprotected sex, the more likely they are to prevent pregnancy.
