About this Medication
What the Medication Is Used For
NorLevo is an emergency or backup contraceptive.
NorLevo can prevent pregnancy after a contraceptive accident (such as a broken condom) or when no form of birth control was used. Treatment is most effective if used in the first 72 hours (3 days) following unprotected sex.
NorLevo cannot terminate an existing pregnancy. Although there is no scientific evidence that NorLevo would harm a developing embryo, women who are already pregnant should not use the product.
NorLevo should not be used in place of regular contraception.
What It Does
NorLevo acts as an emergency contraceptive by stopping or delaying the release of an egg from the ovary, thus preventing sperm and egg from uniting (fertilization). NorLevo is not effective once a pregnancy has started, that is once the fertilized egg has attached to the wall of the uterus. It cannot stop a fertilized egg from attaching to the womb.
NorLevo can be used following any unprotected act of sexual intercourse, including:
- when no contraceptive method has been used,
- when a contraceptive method may have failed, such as:
- forgotten, ruptured, misuse or slippage of condom;
- missed oral contraceptive pill;
- expelled intrauterine device (IUD);
- early removal, breakage or dislodgment of a vaginal diaphragm or of a contraceptive cap;
- failure to withdraw before ejaculation ;
- sexual intercourse during the supposedly fertile period when relying on periodic abstinence (temperature method);
- in cases of sexual assault (rape);
- a delay in starting a new packet of oral contraceptives;
- a delay in getting a scheduled contraceptive injection.
NorLevo is not as effective in preventing pregnancy as the use of most other birth control methods (e.g. oral contraceptive pills, IUS’s, IUD’s).

- you have a confirmed or suspected pregnancy;
- you are allergic to it, or to any of the components of its formulation (for list of components, see the section “What the nonmedicinal ingredients are”);
- you have abnormal vaginal bleeding.

Warnings and Precautions
Serious Warnings and Precautions
NorLevo provides no protection against HIV/AIDS and other sexually transmitted diseases (STDs), such as syphilis, gonorrhoea, chlamydia, and herpes. If you are worried about whether you may have been infected with HIV/AIDS, or other sexually transmitted diseases, talk to your health care provider about your concerns and ask how you can protect yourself in the future.
If your period is delayed by more than 5 to 7 days, you should contact your doctor and have a pregnancy test done.
NorLevo is for Emergency Contraceptive Use Only and should not be used on regular basis.
NorLevo provides only short-term protection against pregnancy. Sexual activity that takes place after taking NorLevo can still result in pregnancy if no contraceptive is used. You must abstain from sex or use another barrier method of birth control until your next normal period to make sure you do not get pregnant.
BEFORE you use NorLevo talk to your doctor or pharmacist if:
- you are allergic to levonorgestrel or any component of NorLevo tablet;
- you are pregnant or breast-feeding;
- you have recent unusual vaginal bleeding (during your last cycle);
- known or suspected breast cancer;
- you have active liver disease or tumor
- you weigh 75 kg (165 lbs) or more.
Interactions with this Medication
Drugs that decrease the efficacy of NorLevo include:
- Anticonvulsants (phenobarbital, phenytoin, primidone, carbamazepine)
- Hypericum perforatum (St. John wort)
- Ulipristal acetate
If you are taking one of the above medications, and your period is delayed by more than 5 to 7 days after using NorLevo, you should contact your doctor and/or have a pregnancy test done.
Tell your doctor if you have taken NorLevo within 3 days of a Pap test, as it may affect your results.
Proper Use of this Medication
NorLevo may prevent pregnancy if the two tablets are taken together within 72 hours (3 days) and preferably with 12 hours, after a contraceptive accident or other unprotected sexual intercourse. You should not delay starting treatment. NorLevo is more effective the sooner you start taking the tablets after unprotected intercourse.
Tablets should be taken with a glass of water.
If you vomit within three (3) hours after swallowing the tablets
- If you can see the tablets in the vomit, you should purchase and take a second dose as soon as possible.
- If the tablets are not visible in the vomit, call you doctor or pharmacist as you might need another dose.
NorLevo can be taken at any time during your menstrual cycle.
If you are sexually active and do not wish to become pregnant, you should use a reliable method of contraception on a regular basis. If you want more information about regular contraceptives or if you are having trouble using a method, ask your health professional for help in choosing a method that works for you.
NorLevo is less effective in women weighing 75 kg (165 lbs) or more and not effective in women weighing more than 80 kg (176 lbs). If your weight is 75 kg or more, ask your health professional for advice on alternative methods of emergency contraception.
You should discontinue nursing for at least 8 h, but not more than 24h, after emergency contraception. Any milk expressed during this period should be discarded.
If more than 72 hours (3 days) have passed since unprotected sex occurred, NorLevo may not be effective. See your health care provider as soon as possible to discuss other options.
NorLevo is not as effective in preventing pregnancy as the use of most other birth control methods (e.g. oral contraceptive pills, IUS’s, IUD’s or condoms, etc.). It should not be relied on for routine birth control by sexually active women.
Contact your local poison control center or emergency room immediately. Symptoms of overdose may include nausea, vomiting, vaginal bleeding and may lead to menstrual cycle disturbances.
