1. WHAT LEVONELLE ONE STEP IS AND WHAT IT IS USED FOR
Levonelle One Step is an emergency contraceptive that can be used within 72 hours (3 days) of unprotected sex or
if your usual contraceptive method has failed.
Levonelle One Step contains a synthetic hormone like substance called levonorgestrel. It prevents about 84% of
expected pregnancies when you take it within 72 hours of having unprotected sex. It will not prevent a pregnancy
every time and is more effective if you take it as soon as possible after unprotected sex. It is better to take it within
12 hours rather than delay until the third day.
Levonelle One Step is thought to work by:
• stopping your ovaries from releasing an egg;
• preventing sperm from fertilising any egg you may have already released;
• stopping a fertilised egg from attaching itself to your womb lining.
Levonelle One Step can only prevent you becoming pregnant if you take it within 72 hours of unprotected sex. It
does not work if you are already pregnant. If you have unprotected sex after taking Levonelle One Step, it will not
stop you from becoming pregnant.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE LEVONELLE ONE STEP
Do not use Levonelle One Step if:
• you are allergic to levonorgestrel or any of the other ingredients of this medicine listed in section 6.
Warnings and precautions
If any of the following applies to you, talk to your doctor before taking Levonelle One Step as emergency contraception
may not be suitable for you. Your doctor may prescribe another type of emergency contraception for you.
• If you are pregnant or think that you may already be pregnant. This medicine will not work if you are already
pregnant. If you are already pregnant, Levonelle One Step cannot terminate pregnancy, so Levonelle One Step
is not an “abortion pill”.
You may already be pregnant if:
• your period is more than 5 days late, or you have experienced unusual bleeding when your next period is due
• you have had unprotected sex more than 72 hours ago, and since your last period.
Children and adolescents
Levonelle One Step is not recommended for young women under 16 years of age without medical supervision.
The use of Levonelle One Step is not advised if:
• you have a disease of your small bowel (such as Crohn’s disease) that inhibits the absorption of the drug
• you have severe liver problems
• you have a history of ectopic pregnancy (where the baby develops somewhere outside the womb)
• you have ever had a disease called salpingitis (inflammation of the Fallopian tubes).
A previous ectopic pregnancy or previous infection of the fallopian tubes increases the risk of a new ectopic
Your doctor may decide that Levonelle One Step is not suitable for you, or that another type of emergency
contraception would be better for you.
In all women, emergency contraception should be taken as soon as possible after unprotected intercourse. There
is some evidence that Levonelle One Step may be less effective with increasing body weight or body mass index
(BMI), but these data were limited and inconclusive.
Therefore, Levonelle One Step is still recommended for all women regardless of their weight or BMI.
You are advised to speak to a healthcare professional if you are concerned about any problems related to taking
If you are worried about sexually transmitted diseases
If you did not use a condom (or if it has been torn or slid down) during the intercourse, it might be possible that you
have caught a sexually transmitted disease or the HIV virus.
This medicine will not protect you against sexually transmitted diseases, only condoms can do this. Ask your
doctor, nurse, family planning clinic or pharmacist for advice if you are worried about this.
Other medicines and Levonelle One Step
Tell your pharmacist or doctor if you are taking or have recently taken any other medicines, including medicines
obtained without a prescription or herbal medicines.
Some medicines may prevent Levonelle One Step from working effectively. If you have used any of the medicines
below during the last 4 weeks, Levonelle One Step may be less suitable for you. Your doctor may prescribe another
type of (non-hormonal) emergency contraceptive, i.e. a copper intrauterine device (Cu-IUD). If this is not an option
for you or if you are unable to see your doctor promptly, you can take a double dose of Levonelle One Step:
• barbiturates and other medicines (used to treat epilepsy (for example, primidone, phenytoin, and
• medicines used to treat tuberculosis (for example, rifampicin, rifabutin)
• a treatment for HIV infection (ritonavir, efavirenz)
• a medicine used to treat fungal infections (griseofulvin)
• herbal remedies containing St John’s Wort (Hypericum perforatum)
Speak to your pharmacist or doctor if you need further advice on the correct dose for you.
Consult your doctor as soon as possible after taking the tablets for further advice on a reliable form of regular
contraception and to exclude a pregnancy. (See section also 3 “How to take Levonelle One Step” for further advice).
Levonelle One Step may also affect how well other medicines work
• a medicine called ciclosporin (suppresses the immune system).
How often can you use Levonelle One Step
You should only use Levonelle One Step in emergencies and not as a regular method of contraception. If
Levonelle One Step is used more than once in a menstrual cycle it is more likely to upset your menstrual cycle
Levonelle One Step does not work as well as regular methods of contraception. Your doctor, practice nurse or
family planning clinic can tell you about long-term methods of contraception which are more effective in preventing
you from getting pregnant.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or
pharmacist for advice before taking this medicine.
You should not take this medicine if you are already pregnant. If you do become pregnant even after taking this
medicine, it is important that you see your doctor. There is no evidence that Levonelle One Step will harm a baby
that develops in your uterus/womb if you use Levonelle One Step as described. Nevertheless, your doctor may
want to check that the pregnancy is not ectopic (where the baby develops somewhere outside the womb). This is
especially important if you develop severe abdominal pain after taking Levonelle One Step or if you have
previously had an ectopic pregnancy, Fallopian tube surgery or pelvic inflammatory disease.
Very small amounts of the active ingredient of this medicine may appear in your breast milk. This is not thought to
be harmful to the baby, but if you are worried you can take your tablet immediately after a breast-feeding and avoid
nursing at least 8 hours following tablet taking. In this way you are taking your tablet well before the next feed and
reducing the amount of active ingredient your baby may take in with the breast milk.
Levonelle One Step increases the possibility of menstruation disturbances which can sometimes lead to earlier or
later ovulation date. These changes can result in modified fertility date, however there are no fertility data in the
Driving and using machines
Your Levonelle One Step tablet is unlikely to affect your ability to drive a car or use machines. However, if you feel
tired or dizzy do not drive or operate machinery.
Levonelle One Step tablet contains lactose
In case of milk sugar (lactose) intolerance it should be considered that each Levonelle One Step tablet also
contains 142.5 mg lactose monohydrate.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before
taking this medicinal product.
3. HOW TO TAKE LEVONELLE ONE STEP
Always use this medicine exactly as described in the leaflet or as your pharmacist has told you. Check with your
doctor or pharmacist if you are not sure.
Use in children and adolescents
This medicine is not recommended for use in children. If you are under 16, you must visit your doctor or family
planning clinic to get emergency contraception.
• Take the tablet as soon as possible, preferably within 12 hours, and no later than 72 hours (3 days) after you
have had unprotected sex. Levonelle One Step can be taken at any time in your menstrual cycle assuming you
are not already pregnant or think you may be pregnant. Do not chew but swallow the tablet whole with water.
Do not delay taking the tablet. The tablet works best the sooner you take it after having unprotected sex.
• If you are using one of the medicines that may prevent Levonelle One Step from working properly (see section
above “Other medicines and Levonelle One Step”) or if you have used one of these medicines in the past 4
weeks, Levonelle One Step may work less effectively for you. Your doctor may prescribe another type of (nonhormonal) emergency contraceptive, i.e. a copper intrauterine device (Cu-IUD). If this is not an option for you or
if you are unable to see your doctor promptly, you can take a double dose of Levonelle One Step (i.e. 2 tablets
taken together at the same time).
• If you are already using a regular method of contraception such as the contraceptive pill, you can continue to
take this at your regular times.
If another unprotected intercourse takes place after the use of Levonelle One Step (also if this is during the same
menstrual cycle), the tablet will not exert its contraceptive effect and there is again the risk of pregnancy.
What to do if you are sick (vomit)
If you are sick (vomit) within three hours of taking the tablet, you should take another tablet. You will need to
contact your pharmacist, doctor, practice nurse or family planning clinic immediately for one more tablet.
After you have taken Levonelle One Step
After you have taken Levonelle One Step, if you want to have sex, and are not using the contraceptive pill, you
should use condoms or a cap plus spermicide until your next menstrual period. This is because Levonelle One
Step won’t work if you have unprotected sex again, before your next period is due.
After you have taken Levonelle One Step, you are advised to make an appointment to see your doctor about three
weeks later, to make sure that Levonelle One Step has worked. If your period is more than 5 days late or is
unusually light or unusually heavy, you should contact your doctor as soon as possible. If you do become pregnant
even after taking this medicine, it is important that you see your doctor.
Your doctor can also tell you about longer-term methods of contraception which are more effective in preventing
you from getting pregnant.
If you continue to use regular hormonal contraception such as the contraceptive pill and you do not have a bleed in
your pill-free period, see your doctor to make sure you are not pregnant.
Your next period after you took Levonelle One Step
After the use of Levonelle One Step, your period is usually normal and will start at the usual day; however
sometimes, this will be a few days later or earlier. If your period starts more than 5 days later than expected, an
‘abnormal’ bleeding occurs at that time or if you think that you might be pregnant, you should check whether you
are pregnant by a pregnancy test.
If you take more Levonelle One Step than you should
Although there have been no reports of serious harmful effects from taking too many tablets at once, you may feel
sick, actually be sick (vomit), or have vaginal bleeding. You should ask your pharmacist, doctor, practice nurse or
family planning clinic for advice, especially if you have been sick, as the tablet may not have worked properly.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
