Teva-Levonorgestrel: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

What the medication is used for:

TEVA-LEVONORGESTREL is an emergency or backup contraceptive.

TEVA-LEVONORGESTREL 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 .

TEVA-LEVONORGESTREL cannot terminate an existing pregnancy. Although there is no scientific evidence that TEVA-LEVONORGESTREL would harm a developing embryo, women who are already pregnant should not use this product.

TEVA-LEVONORGESTREL should not be used in place of regular contraception. It does not work as well as most other contraceptives used correctly.

What it does:

TEVA-LEVONORGESTREL acts as an emergency contraceptive by preventing the release of an egg from the ovary, or preventing sperm and egg from uniting. In addition, TEVA-LEVONORGESTREL may prevent the fertilized egg from attaching to the wall of the uterus. TEVA-LEVONORGESTREL is not effective once a pregnancy has started, that is once the fertilized egg has attached to the wall of the uterus. TEVA-LEVONORGESTREL does not cause an abortion.

TEVA-LEVONORGESTREL can be used following any unprotected act of sexual intercourse, including:

• When no contraceptive has been used

• When a contraceptive method may have failed, including:

  • Condom rupture, slippage, or misuse

    • Diaphragm or cap dislodgment, breakage or early removal
    • Failure to withdraw before ejaculation
    • Miscalculation of the fertile period by women practising periodic abstinence
    • IUD expulsion
    • Missed oral contraceptives
    • A delay in starting a new packet of oral contraceptives
    • A delay in getting a scheduled contraceptive injection
    • In cases of sexual assault (rape)

WARNINGS AND PRECAUTIONS

Serious Warnings and Precautions

• TEVA-LEVONORGESTREL 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 professional about your concerns and ask how you can protect yourself in the future.
• If your period is delayed more than 1 week, you should contact your doctor and have a pregnancy test done.

TEVA-LEVONORGESTREL is for Emergency Contraceptive Use Only and should not be used on a regular basis. TEVA-LEVONORGESTREL is not as effective in preventing pregnancy as most other birth control methods (e.g. oral contraceptive pills, IUDs, implants or condoms, etc.). It should not be relied on for routine birth control by sexually active women.

TEVA-LEVONORGESTREL provides only short-term protection against pregnancy. Sexual activity that takes place later 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 TEVA-LEVONORGESTREL, talk to your doctor or pharmacist if you have now or have previously had any of the following conditions:

• Unusual vaginal bleeding that has not yet been diagnosed
• Known or suspected breast cancer
• Active liver disease or tumor
• You have diabetes
• You have hypertension (a heart condition)
• You are pregnant or breast feeding
• you weigh 75 kg (165 lbs) or more.

INTERACTIONS WITH THIS MEDICATION

Before you use TEVA-LEVONORGESTREL, talk to your doctor or pharmacist if you are taking any of the following drugs:

Drugs that may decrease the efficacy of TEVA-LEVONORGESTREL include:

• Anticonvulsant drugs (phenytoin, carbamazepine, primidone, phenobarbital)

• rifampicin
• rifabutin
• griseofulvin
• Hypericum perforatum (St. John’s wort)

If your period is delayed more than 1 week and you were taking any of these medications, you should contact your doctor or pharmacist and have a pregnancy test done.

Tell your doctor if you have taken TEVA-LEVONORGESTREL within 3 days of a Pap test, as it may affect your results.

PROPER USE OF THIS MEDICATION

Usual dose:

TEVA-LEVONORGESTREL can prevent pregnancy if the 2 tablets are taken together within 72 hours (3 days) and preferably within 12 hours, after a contraceptive accident or unprotected sex (sex without birth control). Do not delay starting treatment. TEVA-LEVONORGESTREL is more effective the sooner you start after unprotected intercourse.

TEVA-LEVONORGESTREL can be taken with a glass of water.

If you vomit within 2 hours of taking TEVA-LEVONORGESTREL, call your doctor or pharmacist as you might need another dose.

Important: If more than 72 hours (3 days) have passed since unprotected sex occurred, TEVA-LEVONORGESTREL may not be effective. See your health professional as soon as possible to discuss other options.

Although the risk of pregnancy is highest in the middle of the menstrual cycle (possibly as early as day 10 after the beginning of your last period), pregnancy can occur at other times during the menstrual cycle. TEVA-LEVONORGESTREL can be administered anytime during your monthly cycle if you are worried about an unwanted pregnancy.

The treatment does not bring on menstruation. You may experience spotting a few days after taking TEVA-LEVONORGESTREL, but this is not a period. Your next menstrual period should come on time (or a few days early or late). If your period is delayed more than a week or if you have any other cause for concern, talk to a health professional. More than occasional use (more than once in a menstrual cycle or more than once a month) may upset your menstrual cycle (period).

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.

TEVA-LEVONORGESTREL 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.

Overdose:

Symptoms of overdose may include nausea, vomiting, vaginal bleeding, and may lead to menstrual cycle disturbances.
