Understanding Emergency Contraceptive Pills

Emergency contraceptive pills (ECPs) are designed to prevent pregnancy after unprotected sex. They are not a form of regular contraception and should only be used in emergencies. The two primary ECPs available are ellaOne and Levonelle, which contain different active ingredients and have different usage instructions. Both pills work primarily by delaying or preventing ovulation (the release of an egg), which prevents fertilization from occurring.

ellaOne (Ulipristal Acetate)

ellaOne contains ulipristal acetate and is effective for up to 120 hours (5 days) after unprotected sex. It is considered highly effective, with some data suggesting it can be 2.5 times more effective than Levonelle when taken within 24 hours. ellaOne's effectiveness is estimated to be around 85% for the full 120-hour window. Its effectiveness may be reduced in individuals weighing over 195 pounds (approx. 88kg). If breastfeeding, discarding breast milk for 24 hours after taking ellaOne is recommended. Certain medications can reduce its effectiveness.

Levonelle (Levonorgestrel)

Levonelle contains levonorgestrel, a synthetic hormone, and is effective for up to 72 hours (3 days) after unprotected sex. Its effectiveness decreases over time, being most effective within the first 24 hours (around 95% efficacy) and dropping to about 58% by 72 hours. Levonelle's effectiveness is reduced in individuals weighing over 70kg or with a BMI over 26. It is considered safe for breastfeeding, though small amounts pass into breast milk. Some medications can affect Levonelle's efficacy.

Both pills work primarily by preventing or delaying ovulation and share similar common side effects such as nausea and headache. Levonelle is often available over-the-counter, while ellaOne may require a prescription in some areas.

Understanding Side Effects and Interactions

Both ECPs are generally safe with no serious long-term side effects. Common temporary side effects include nausea, headaches, and abdominal pain. They can also affect your next period. If you vomit within three hours of taking ellaOne or within two hours of taking Levonelle, you may need to take another dose. It's vital to discuss any other medications you are taking with a healthcare provider due to potential drug interactions that could reduce the ECP's effectiveness.

Making the Best Choice for You

To determine the best option, consider the time since unprotected sex, your medical history, and consult a healthcare provider. ellaOne is suitable if it has been longer than 72 hours. Levonelle may be preferred if breastfeeding and you wish to avoid a break. If body weight is a concern, ellaOne might be better than Levonelle, but a copper IUD is the most effective choice regardless of these factors.

Conclusion

Both ellaOne and Levonelle are effective emergency contraceptives, but ellaOne offers a longer effective window (up to 120 hours) and is generally more effective, especially after 24 hours. Levonelle is effective for up to 72 hours, but its efficacy declines sooner. Taking either pill as soon as possible maximizes effectiveness. Always seek medical advice to choose the best option for your circumstances. Remember, these pills do not protect against STIs, so condoms are necessary for disease prevention and regular contraception. For more information on emergency contraception, consult resources like Planned Parenthood.
