|Plan B One-Step|
The morning-after pill is a type of emergency birth control (contraception). The purpose of emergency contraception is to prevent pregnancy after a woman has had unprotected sex. Morning-after pills contain either levonorgestrel (Plan B One-Step, Next Choice) or ulipristal (Ella).
Plan B One-Step, Next Choice and Ella are the only morning-after pills that have Food and Drug Administration approval in the U.S. However, other brands of morning-after pills are available around the world.
Plan B One-Step is available over-the-counter — without a prescription — to women age 15 and older. Next Choice is available over-the-counter for women age 17 and older. Ella is available only with a prescription from your doctor or health care provider.
