Just like birth control, there is more than one type of emergency contraception. Although it’s casually referred to as “morning-after pill,” emergency contraception can work beyond the morning after unprotected sex. One of those types is Ella, which is the most effective emergency contraception pill available. Here are five fast facts about Ella and how it works to prevent pregnancy.

Ella is effective up to five days after unprotected sex

Effectiveness is one of the main differences between Ella and Plan B. The morning-after pill, also known as Plan B, is effective only up to 72 hours after unprotected sex. Plan B is also less effective the later you take it in that 72-hour window. Ella is effective up to five days after unprotected sex and does not lose effectiveness over that time.

Ella requires a prescription from the doctor

Another important difference between Ella and the morning-after pill is that Ella is not available over the counter at the pharmacy. You need a prescription from your doctor or nurse. Fortunately, Ella is available at all Planned Parenthood locations by appointment (including virtual appointments). If you want to know more about picking up EC at the pharmacy, and what’s available and what’s not, check out our emergency contraception FAQ.

Ella is better for those who weigh 155 lbs or more

Between Plan B and Ella, Ella is the emergency contraception that is most effective for people with a Body Mass Index (BMI) of 30 or less. It is not effective for women who have a BMI of 35 and more. In terms of weight, Ella is most effective for those who weigh between 155 to 195 lbs. If you weigh more than 195 lbs and need emergency contraception, please talk to your doctor.

Although they are both types of emergency contraception, they affect people’s bodies differently because Plan B and Ella have different medicines in them. Plan B contains levonorgestrel, which is similar to what’s in the birth control pill but with a higher amount. Ella contains ulipristal, which prevents and delays ovulation like Plan B but can also make it harder for a fertilized egg to embed in the uterus.

Ella can be less effective when used with hormonal birth control

If you use hormonal birth control, such as the pill, shot or ring, taking Ella at the same time can reduce the effectiveness of both Ella and your birth control. If you typically use hormonal birth control to prevent pregnancy, and you need to take Ella, then it’s best to wait at least six days after taking Ella to start or restart using your birth control. If you don’t have to take Ella, then Plan B or the copper IUD are better EC choices if you use hormonal birth control.

In the meantime, make sure to use backup birth control methods like condoms to prevent pregnancy. If you take Ella, and need emergency contraception again before your next period, make sure to take Ella again and not Plan B or any other generics.
