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 or after her birth control method has failed.
The morning-after pill is intended for back-up contraception only, not as a primary method of birth control. Morning-after pills contain either levonorgestrel (Plan B One-Step) or ulipristal acetate (ella).
Plan B One-Step is available over-the-counter without a prescription; ulipristal is available only with a prescription from your doctor or health care provider.
