Ella® (ulipristal acetate)
Prescription-only Ella can be taken up to 120 hours (five days) after unprotected sex, but the sooner you take it the better. It may be more effective than Plan B for women who weigh 165+ pounds.
Note: If you take birth control pills the medication in Ella might make your birth control pills ineffective, so you should use a back-up method of contraception (like condoms) if you have sex within 7 days of restarting birth control pills. If you are breastfeeding, the CDC recommends recommends pumping and discarding for 24 hours after taking Ella, though there may be trace amounts of Ella in breastmilk for up to 5 days.
