When should I take it?
Plan B One Step is designed to be taken soon after unprotected sex. This includes times when a condom bursts, or if you have had unprotected sex when your contraceptive pill might not have been as effective after a stomach upset.
You can take Plan B One-Step if:
- You didn’t use any contraception at all
- The condom broke or came off
- Your diaphragm slipped out of place
- You realise that you’ve missed at least two or three active contraceptive pills in a row
- You’ve been sick or had an upset stomach, and you think your pill might not have worked.
Plan B and any other types of emergency contraception won’t protect you from pregnancy if if you have unprotected sex again after you’ve taken the pill.
Plan B, along with other brands of levonorgestrel morning-after pill works best the faster you take it. This type of emergency contraception is more likely to be effective if you take it very quickly after having unprotected sex. It works best up to three days (72 hours) afterwards.
