Are levonelle and ellaone safe to use?

Last Updated on January 17, 2023 by Daniel Cooper

Levonorgestrel and ulipristal acetate, two emergency contraceptive drugs available over the counter and by prescription, are safe to use. 

Emergency contraception is used when other forms of birth control fail or aren’t used at all. Levonorgestrel (brand name: Plan B One-Step) can be taken up to 72 hours after unprotected intercourse to prevent pregnancy. Ulipristal acetate (brand name: ellaOne) can be taken up to 120 hours after unprotected intercourse.


Both levonorgestrel and ulipristal acetate work by delaying ovulation — when an egg is released from the ovaries — which prevents fertilization from taking place. They do not cause an abortion, terminate a pregnancy or affect an established pregnancy.


Levonorgestrel has been studied extensively and is considered very safe, with fewer than one in every 100 women experiencing side effects like dizziness, headache, fatigue and nausea. Ulipristal acetate has also been well studied, but few studies have compared it directly to levonorgestrel. Its safety profile appears to be similar to that of levonorgestrel. Side effects are generally mild and include abdominal pain and nausea. In rare cases, the drugs can cause serious side effects such as blurred vision or chest pain that should be reported immediately to a doctor.


Few examples:

Both medications may interact with certain drugs. It’s important to check with your doctor or pharmacist before taking either levonorgestrel or ulipristal acetate if you take any other medications, including herbal supplements.


It’s also important to remember that emergency contraception is not the same as regular birth control. 

Emergency contraception should only be used in an emergency situation and is not intended for routine use. You can get your Morning After Pill at true medical. You should talk to your doctor about what form of birth control is best for you if you’re sexually active and want to prevent pregnancy. With regular use of effective birth control, you can reduce the need for emergency contraception.


If you become pregnant after taking either drug or don’t experience any adverse reactions to the drug, you can continue the pregnancy.

 Both levonorgestrel and ulipristal acetate are considered safe to use in the short term for emergency contraception. However, if you’re looking for a long-term birth control option, talk to your doctor about other options. You may also want to consider taking Plan B One-Step or ellaOne as soon as possible after unprotected intercourse, even if it has been less than 72 hours since that time, for increased efficacy.


No matter which emergency contraceptive method you choose, it is important to speak with your doctor or pharmacist before using to make sure you understand how and when to take the medication correctly. Your healthcare provider can also answer any questions or concerns you may have.


Overall, both levonorgestrel and ulipristal acetate are safe and effective ways to prevent pregnancy after unprotected intercourse.

 If you think you need emergency contraception, talk to your doctor or pharmacist to decide which option is best for you. They can provide more information about how the medications work and whether they’re right for your individual situation.


Remember, levonorgestrel and ulipristal acetate are safe to use if used as directed. Emergency contraception should not be used as a primary form of birth control, but it can help protect you if other forms of contraception fail or aren’t available. Talk with your healthcare provider to decide which emergency contraceptive method is right for you.
