About Levonelle
-
-
Levonelle is an emergency contraceptive pill, also known as a ‘morning after pill’. You can take Levonelle to prevent pregnancy after having unprotected sex. It is effective for up to 72 hours (3 days) after having sex.
You can take Levonelle if you are on other types of birth control, like the contraceptive pill. Levonelle does not, however, protect you against sexually transmitted infections (STIs).
-
-
Levonelle works by: stopping your ovaries from releasing an egg, a process known as ovulation; making it harder for sperm to fertilise any released egg
Levonelle contains the active ingredient levonorgestrel which is a synthetic version of the natural hormone progesterone, normally produced by the ovaries to delay the release of an egg (ovulation). Ovulation usually occurs about halfway through your menstrual cycle, or roughly 2 weeks before your period. Levonelle is not effective if you’re taking it after ovulation.
Everyone’s menstrual cycle is different, so it’s a good idea to track what stage of your cycle you are in. If you have already ovulated, it’s best to use the copper intrauterine device (IUD) as a form of emergency contraception. You can get this fitted at a sexual health or family planning clinic.
Does Levonelle work if you’ve already ovulated?
No, Levonelle prevents pregnancy by stopping ovulation. If you have already ovulated and an egg has been released, Levonelle will not prevent pregnancy. If you think ovulation may have happened and that you might be pregnant, you should speak to your doctor. They can discuss any further options that are available to you.
How quickly does Levonelle work?
Levonelle gets to work straight away as soon as you take it. It is up to 99% effective if you take it as soon as possible (within 12 to 24 hours of unprotected sex).
It prevents 84% of pregnancies when taken within 72 hours (3 days) after having unprotected sex.
-
-
After unprotected sex or a contraceptive failure take 1 Levonelle tablet:
- by swallowing the tablet whole with water (do not chew)
- with or without food
- even if you are already taking regular contraception (like the contraceptive pill), you can continue to take it at your regular times
How often can I use Levonelle?
If you find yourself needing to take emergency contraception on a regular basis or multiple times a month, you should consider taking a form of regular contraception like the contraceptive pill or alternative non-hormonal birth control options.
If you have questions about how often a morning after pill can be used, you should speak to your doctor.
Should I keep taking my contraceptive pill after taking Levonelle?
Yes, it is recommended that you take your next contraceptive pill within 12 hours of taking Levonelle. You should then take your contraceptive pill as normal going forward.
You should also use alternative contraception, such as condoms, for:
- 9 days if you use the combined pill Qlaira
- 2 days if you take a progestogen-only pill
What should I do if I vomit after taking Levonelle?
Vomiting is one of the known side effects of Levonelle. If you vomit after taking Levonelle and it has been less than 3 hours since you took the tablet, you will need to get another. Speak to a pharmacist, doctor, or sexual health clinic so you can get another dose.
If you vomit after taking Levonelle and it has been longer than 3 hours, your body will have absorbed the medication and it is not recommended to take another tablet unless you have unprotected sex again.

-
The only way to know for sure if Levonelle or any form of emergency contraception has worked is by waiting for your next period. If your period arrives when it should, you are most likely not pregnant. If your period is late, you can take a pregnancy test.

Can you get Levonelle over the counter?
Yes, Levonelle is available over the counter from most pharmacies or reputable online doctors, such as ZAVA. You will still need to answer a few questions for the pharmacist to make sure it’s safe and suitable for you.
How long after taking Levonelle should I do a pregnancy test?
A pregnancy test can normally detect pregnancy 21 days (3 weeks) after unprotected sex. If you want to check whether Levonelle has worked with a pregnancy test, you should wait at least this long.
What is the difference between Levonelle and ellaOne?
Levonelle and ellaOne contain different active ingredients but both work in similar ways. Levonelle contains levonorgestrel, whereas ellaOne contains ulipristal acetate. They can also be taken at different times. Levonelle is effective up to 72 hours (3 days) after unprotected sex, while ellaOne can be taken up to 120 hours (5 days) after.
Can Levonelle delay your period?
Levonelle can affect your period by making it slightly earlier or later than normal. If your period is more than 5 days late or you experience any abnormal vaginal bleeding, speak to your doctor. You should also do a pregnancy test to check if you are pregnant. If you have taken Levonelle and find out you are pregnant, speak to your doctor.
Can you drink alcohol after taking Levonelle?
Yes, you can drink alcohol after taking Levonelle – alcohol is not known to cause any interactions. If you get side effects like nausea and vomiting, it is best to avoid alcohol until you feel better.
Can Levonelle cause spotting?
Yes, a very common side effect of Levonelle is irregular bleeding. This is usually not a cause for concern but speak to your doctor if you are bleeding heavily or your period is very painful.
Is Levonelle safe?
Yes, Levonelle is safe to take if approved by a doctor or pharmacist, but can sometimes cause some mild side effects. As you are only taking Levonelle as a single dose, it is not likely to cause any long term effects. There is no evidence that Levonelle will affect your ability to have a baby in the future.
Will Levonelle affect my fertility in the future?
Taking Levonelle should not affect your fertility in the future, even if it’s been taken more than once in a short period. However, it is safer and much more effective to use condoms or other methods of contraception regularly and to avoid taking Levonelle too often. Levonelle, or any other form of emergency contraception, should only be used in emergencies, and not as a regular form of contraception.
Do you bleed after taking Levonelle?
Some people may experience irregular bleeding after using Levonelle. If you’re unsure whether your bleeding is from your period, you can take a pregnancy test as long as it is at least 21 days (3 weeks) since you had unprotected sex.
Can Levonelle cause mood swings?
Levonelle contains hormones which can affect mood, and a common side effect of the medication is mood swings. They normally go away after a few days, but if they do not then you should speak to your doctor.
Does Levonelle stop sexually transmitted infections (STIs)?
No, Levonelle will only delay ovulation and prevent pregnancy. You are not protected from sexually transmitted infections (STIs) when you take it. You should use alternative contraception such as condoms in order to prevent STIs.
Does Levonelle cause stomach pain?
You may experience some stomach pain after using Levonelle. This is normally mild and will go away within a few days. If the pain becomes unmanageable or does not go away, you should speak to your doctor.
What if I vomit after taking Levonelle?
If you vomit after taking Levonelle and it has been less than 3 hours since you took the tablet, you will need to get another. Speak to a pharmacist, doctor, or sexual health clinic so you can get another dose. If you vomit after taking Levonelle and it has been longer than 3 hours, your body will have absorbed the medication and it is not recommended to take another tablet unless you have unprotected sex again. A known side effect of Levonelle is vomiting, but this should pass within a few days.
Can Levonelle delay your period?
Yes, Levonelle can make your period come earlier or later than usual. Speak to your doctor and take a pregnancy test if your period is delayed for longer than 5 days.
What if I take Levonelle too late?
If you take Levonelle more than 72 hours (3 days) late, it will not be effective. However there are other emergency contraception options like ellaOne that are effective after unprotected sex for up to 120 hours (5 days). ellaOne is available to request with ZAVA online doctor. If you have taken Levonelle too late and have concerns or questions, you should speak with your doctor.
