Can I take the morning-after pill at night?

Yes. You can take emergency contraception (a.k.a. the morning-after pill) at any time of day for up to 5 days after unprotected sex. For over-the-counter emergency contraception pills like Plan B One-Step, Next Choice, Next Choice One Dose, and levonorgestrel, the sooner you take them, the more effective they are and work best within 3 days. The prescription emergency contraceptive pill (ella) doesn’t decrease in effectiveness over those 5 days.
