Emergency Contraception
76% Effective, One time use
Brand Names: Plan B, ella, Next Choice
Pills taken after unprotected sex to prevent fertilization and pregnancy. To be effective, must be taken as soon as possible but no more than 5 days after unprotected sex. The sooner you take emergency contraception, the more effective it is at preventing pregnancy. Emergency contraception does not work if you are already pregnant. If you are at least 17 years old, you can go to the drug store and ask the pharmacist for emergency contraception. If you are younger than 17, a provider can write you a prescription.
