Patient Information for ella
Read this Patient Information Leaflet before you take ella. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment.
What is ella?
ella is a prescription emergency contraceptive that reduces your chance of becoming pregnant if your birth control fails or you have unprotected sex.
ella should not be used as your regular birth control. It is very important that you have a reliable form of birth control that is right for you.
ella will not protect you against HIV infection (AIDS) and other sexually transmitted diseases (STDs).
Who should not take ella?
Tell your healthcare provider about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements.
Using other medicines may affect how ella works. These include St. John’s Wort, phenytoin, rifampin, phenobarbital, and carbamazepine. Talk to your healthcare provider if you are currently using these medications.
Talk to your healthcare provider if you use hormonal birth control. Using ella may make your regular hormonal birth control method less effective. After using ella, you should use a reliable barrier method of birth control (such as a condom with spermicide) during any other times that you have sex in that same menstrual cycle.
Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.
When is it not appropriate to use ella?
How does ella work?

How effective is ella?
If ella is taken as directed, it will reduce the chance that you will get pregnant. ella is not effective in every case. ella is only to be used for a single episode of unprotected intercourse. Be sure to use a regular birth control method the next time you have sex.
ella and other emergency contraceptives may be less effective in women with a body mass index (BMI) > 30 kg/m2.
What if I am already pregnant and use ella?
ella should not be taken if you are already pregnant. There is little information on whether ella would harm a developing baby. Contact your healthcare provider if you think you may be pregnant and have taken ella. ella is not for use to terminate an existing pregnancy.
What should I do if my menstrual period is delayed beyond 1 week or I have severe lower stomach (abdominal) pain?
After taking ella, your next menstrual period may begin a few days earlier or later than expected. If your period is more than 7 days later than expected, you may be pregnant. You should get a pregnancy test and follow up with your healthcare provider.
If you have severe lower stomach (abdominal) pain about 3 to 5 weeks after taking ella, you may have a pregnancy outside of the uterus (womb), which is called an ectopic or tubal pregnancy. An ectopic pregnancy is a serious condition that needs medical treatment right away. Call your healthcare provider or go to the nearest emergency room right away if you think you may have an ectopic pregnancy.
How often can I use ella?
ella is meant for emergency contraception only, and is not to be used frequently or as a regular birth control. If you need to use emergency contraception often, talk to your healthcare provider and learn about methods for birth control and sexually transmitted disease prevention that are right for you.
