What is Ella?
Ella is a prescription-only emergency contraceptive pill designed to prevent pregnancy after unprotected sex or contraceptive failure. It contains ulipristal acetate, which works by delaying or inhibiting ovulation. Ella is effective for up to 5 days (120 hours) after unprotected intercourse, but it's most effective when taken as soon as possible.
How Does Ella Work?
Ella functions by postponing the release of an egg from the ovary, thereby preventing fertilization. It does not terminate an existing pregnancy and is not effective if ovulation has already occurred.
How Effective is Ella?
When taken within 24 hours after unprotected sex, Ella reduces the risk of pregnancy by approximately 85%. Its effectiveness diminishes the longer you wait, so prompt administration is crucial.
Does Body Weight Affect Ella's Effectiveness?
Yes. Ella is more effective than other morning-after pills for individuals weighing over 155 pounds. However, its efficacy may decrease for those over 195 pounds. In such cases, alternative emergency contraception methods, like a copper IUD, might be more reliable.
Can I Take Ella If I'm Already Using Hormonal Birth Control?
Ella can interact with hormonal contraceptives, potentially reducing their effectiveness. It's recommended to wait at least 5 days after taking Ella before resuming hormonal birth control and to use a barrier method, like condoms, during this interval.
What Are the Side Effects of Ella?
Common side effects include:
- Nausea
- Headache
- Abdominal pain
- Dizziness
- Fatigue
- Menstrual changes (e.g., earlier or later periods)
If vomiting occurs within 3 hours of taking Ella, consult a healthcare provider, as another dose may be necessary.

Does Ella Protect Against Sexually Transmitted Infections (STIs)?
No. Ella does not offer protection against STIs. Using condoms is essential to reduce the risk of STI transmission.
Is Ella an Abortion Pill?
No. Ella prevents pregnancy by delaying ovulation. It does not terminate an existing pregnancy and is ineffective if ovulation has already occurred.
Are There Age Restrictions for Using Ella?
Ella is approved for use in individuals aged 18 to 54. It’s not recommended for those over 55 due to potential health risks associated with hormonal changes during menopause.
How Can I Obtain Ella?
In the United States, Ella requires a prescription. You can consult with a healthcare provider or use telemedicine services to obtain a prescription. Once prescribed, Ella can be picked up at a pharmacy.
Can I Take Ella Multiple Times in One Menstrual Cycle?
Ella is intended for single-use per incident of unprotected sex. Taking it multiple times within the same cycle is not recommended, as its safety and efficacy for repeated use in a short period haven’t been thoroughly studied.

What Should I Do If I Vomit After Taking Ella?
If you vomit within 3 hours of taking Ella, its effectiveness may be compromised. Contact your healthcare provider promptly to discuss whether you should take another dose.
Can I Use Ella as Regular Birth Control?
No. Ella is designed for emergency contraception and should not replace regular birth control methods. For ongoing contraception, consider options like daily oral contraceptives, IUDs, or implants.
How Soon Will My Period Return After Taking Ella?
Your next period may come earlier or later than expected and could be lighter or heavier. If your period is more than 7 days late, take a pregnancy test and consult your healthcare provider.
Can I Take Ella If I'm Breastfeeding?
Ella can pass into breast milk. If you’re breastfeeding, discuss with your healthcare provider before taking Ella to understand potential risks and necessary precautions.
What If I Have Unprotected Sex Again After Taking Ella?
Ella does not provide ongoing protection. If you have unprotected sex after taking Ella, you may need another dose or consider other emergency contraception methods. Consult your healthcare provider for guidance.
Is Ella Available Over-the-Counter?
In the U.S., Ella is not available over-the-counter and requires a prescription. However, in some countries, it may be available without a prescription. Always check local regulations and consult with a healthcare provider.
For personalized advice and to determine if Ella is suitable for you, consult with a healthcare provider. They can provide guidance based on your individual health needs and circumstances.
