Levonelle One Step is an emergency contraceptive that can be used after unprotected sex or where a contraceptive method has failed. This type of contraception is often called 'the morning after pill'.
Each pack of Levonelle One Step contains a complete treatment which is one round, white tablet. The tablet contains 1500 microgram of levonorgestrel, which is the active ingredient.
Levonelle One Step also contains the inactive ingredients: potato starch, maize starch, colloidal silica anhydrous, magnesium stearate (E572), talc (E533b), lactose monohydrate.
Levonelle One Step prevents about 84% of expected pregnancies when it is taken within 72 hours (3 days) of unprotected sex. Levonelle One Step will not prevent a pregnancy in every instance, but the tablet is more effective the sooner after unprotected sex it is taken (it is better to take it within 12 hours rather than delay until the third day).
The Levonelle One Step morning after pill is thought to work by:
So Levonelle One Step stops a pregnancy before it is established. It does not work if you are already pregnant.
Please talk to your pharmacist before you take this medicine because emergency contraception might not be suitable for you. Call us up on 0844 357 0115 if in doubt and ask to speak to one of our pharmacists.
Levonelle One Step contains 142.5 mg lactose. This should be taken into account if you have been told by your doctor that you have an intolerance to some sugars.
If you are under 16, you must visit your doctor or family planning clinic to get emergency contraception.
You can use Levonelle One Step at any time during your menstrual cycle, except if your period is late. If your period is late, you should tell your pharmacist.
Before you take this medicine, your pharmacist may check that you are not already pregnant by asking you questions about your periods or when you had sex. If you or your pharmacist think that you might already be pregnant, you will need to have a pregnancy test.
Do not use Levonelle One Step if:
If any of these apply to you, Levonelle One Step may not be suitable for you, or other types of emergency contraception may be better for you.
You should not take this medicine if you are already pregnant. If you have had unprotected sex which was more than 72 hours ago, and since your last period, you may already be pregnant and the treatment won't work. If your last period was more than 5 days late or was unusually light or unusually heavy, you should check with your doctor that you are not 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 but 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.
If you are breast-feeding
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-feed. 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.
If you are taking any other medicines
Tell your pharmacist if you are taking any of the medicines listed in the section 'You should contact your doctor for advice about emergency contraception...'.
If you are not sure about anything, check with your pharmacist, doctor, practice nurse or family planning clinic.
If you are worried about sexually transmitted diseases
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.
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 (period).
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.
If you are sick (vomit) within three hours of taking the morning after pill, you should take another tablet. You will need to contact your pharmacist, doctor, practice nurse or family planning clinic immediately for advice and another tablet.
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.
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. 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.
Like all medicines, Levonelle One Step can have side effects.
If you should need to store your tablet, keep it out of the reach and sight of children and in its original container.
Do not take the tablet after the use by date, which is printed on the pack.
If you are not sure about anything or you have any questions, please ask your pharmacist, doctor, practice nurse or family planning clinic.
