There are two emergency contraceptive pills available in the U.S., and they work a little differently:
- Plan B (levonorgestrel): The most well-known morning-after pill, it works best when taken within 72 hours (three days) of unprotected sex, and is more effective the sooner you take it. Plan B is available over the counter, but a provider can help you confirm it's the right fit and send it to your pharmacy if needed.
- ella® (ulipristal acetate): A prescription emergency contraceptive that remains effective for up to five days after unprotected sex. If it's been more than three days, or you're closer to ovulation, ella® may be the better option. It's also more reliable than Plan B for people with a higher BMI.
The right choice depends on timing, your body, and where you are in your cycle, and a provider can help you figure out which choice makes sense for you.
