Yes. The morning-after pill aka emergency contraception pills can all fail. You want to take them ASAP after contraceptive failure. You can take them up to 5 days after contraceptive failure, but they might not work. With Plan B and its generics within 72 hrs of contraceptive failure, 12% of those with uteri get pregnant. At 0-72 hrs after a contraceptive accident, Ella is 42% more effective than Plan B and its generics.
Emergency contraceptive pills should be just that, used in case of an emergency, and not instead of a regular birth control method. Regular birth control – such as the IUD with hormone, implant, shot, ring, patch, pill are all more effective than emergency contraception.
And if your BMI is 26 or greater, Plan B and its generics do NOT work as well. If your BMI is 30 or more, Plan B and its generics do NOT work at all. That’s why at Pandia Health, we recommend Ella instead of Plan B and its generics because Ella works better at every time point and up to BMIs of 35.
