The AfterPill label says to take one white pill within 72 hours after unprotected sex. This dose contains 1.5 mg of levonorgestrel. However, research indicates that it can be taken up to 120 hours after unprotected sex. The pill is more effective the sooner it is taken, so take AfterPill as soon as possible after unprotected intercourse.
AfterPill is available online only at www.afterpill.com. It is not intended for emergency use (shipping can take up to a week), but is a good option for anyone who wants to have EC available on hand for future use. The product costs $20 + $5 shipping for one pill, or $60 + $5 shipping for 3 pills.
