Overview
Etonogestrel, levonorgestrel, and norethindrone are synthetic progestin contraceptives.
USES: Levonorgestrel is used by women to prevent pregnancy after birth control failure (such as a broken condom) or unprotected sex. This medication is an emergency contraceptive and should not be used as a regular form of birth control. Using this medication will not stop an existing pregnancy or protect you or your partner against sexually transmitted diseases (such as HIV, gonorrhea, chlamydia).
This medication may not work well in women over a certain weight (for example, greater than 164 pounds or 74 kilograms), or if you have used certain other medications within the past month. This effect can result in pregnancy. Talk to your doctor for more details and to see if this medication is right for you (see also Drug Interactions section).

- Postcoital Contraception
Also known as: Emergency Contraception.
Dosing
No dosing information is available for this tab.
Norethindrone is administered orally once daily. The tablets should be taken at the same time each day and continued daily without interruption, including throughout all bleeding episodes. Women should be advised to inform a clinician if prolonged bleeding, amenorrhea, or severe abdominal pain occurs.
Levonorgestrel is administered orally or as a levonorgestrel-releasing intrauterine device.
If vomiting occurs within 2 hours following administration of levonorgestrel (e.g., Plan B One-Step(R), Next Choice One Dose(R)) for postcoital contraception, a clinician should be contacted to discuss the need for repeating the dose. If vomiting occurs within 2 hours following administration of the first or second dose of the levonorgestrel 2-dose regimen for emergency contraception, a clinician should be contacted to discuss the need for taking another dose.
Levonorgestrel-releasing intrauterine system should be inserted into the uterine cavity under strict aseptic conditions following a complete review of the patient's medical and social histories, exclusion of pregnancy, and physical examination (including pelvic examination, Papanicolaou test (Pap smear), and appropriate laboratory tests for other genital diseases (e.g., gonorrhea, chlamydia) as indicated). Special attention should be given to determining whether the woman is at risk for ectopic pregnancy or pelvic inflammatory disease (PID). Patients should be reexamined shortly after the first menstrual period following insertion of the device to verify that the device is properly positioned. The manufacturer's labeling should be consulted for proper methods of inserting and removing the levonorgestrel-releasing intrauterine system and for associated precautions.
Etonogestrel is administered as a nonbiodegradable implant that is inserted subcutaneously in the inner aspect of the upper arm. The manufacturer's labeling should be consulted for the proper method of administration and associated precautions.
