What is Opcicon One-Step?
Opcicon One-Step is used to prevent pregnancy after unprotected sex or failure of other forms of birth control (such as condom breakage, or missing 2 or more birth control pills).
Opcicon One-Step may also be used for purposes not listed in this medication guide.
Opcicon One-Step will not terminate pregnancy if the fertilized egg has already attached to the uterus.
Ask a doctor or pharmacist before taking levonorgestrel if you regularly use medication for seizures, tuberculosis, or HIV/AIDS. Certain other medicines can make levonorgestrel less effective.
Before taking this medicine
Do not use this medicine if you are already pregnant. Opcicon One-Step will not terminate a pregnancy that has already begun (the fertilized egg has attached to the uterus).
Opcicon One-Step is not approved for use by anyone younger than 17 years old.
You should not use levonorgestrel if you are allergic to it.
Ask a doctor or pharmacist before taking levonorgestrel if you regularly use medication for seizures, tuberculosis, or HIV/AIDS. Certain medications can make levonorgestrel less effective as an emergency form of contraception.
Opcicon One-Step is not intended for use as a routine form of birth control and should not be used in this manner. Talk with your doctor about the many forms of birth control available.
Levonorgestrel may slow breast milk production. Tell your doctor if you are breast-feeding.
How should I take Opcicon One-Step?
Use exactly as directed on the label, or as prescribed by your doctor.
Opcicon One-Step must be taken as soon as possible after unprotected sex (no later than 72 hours afterward).
Call your doctor right away if you vomit within 2 hours after taking Opcicon One-Step. Do not take a second dose without first asking your doctor.
Visit your doctor within 3 weeks after taking Opcicon One-Step. A doctor should confirm that you are not pregnant, and that this medicine has not caused any harmful effects.
If your period is late by 1 week or longer after the expected date, you may be pregnant. Get a pregnancy test and contact your doctor if you are pregnant. Opcicon One-Step will not terminate pregnancy if the fertilized egg has attached to the uterus.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Since Opcicon One-Step is used as a single dose, it does not have a daily dosing schedule.
What happens if I overdose?
Because Opcicon One-Step is supplied as a single tablet in an exact strength, an overdose is unlikely to occur when the levonorgestrel is used as directed. Do not take more than one tablet at the same time.
What should I avoid while taking Opcicon One-Step?
Opcicon One-Step will not protect you from sexually transmitted diseases–including HIV and AIDS. Using a condom is the only way to protect yourself from these diseases. Avoid having unprotected sex.
Opcicon One-Step side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor or seek emergency medical help if you have severe pain in your lower stomach or side. This could be a sign of a tubal pregnancy (a pregnancy that implants in the fallopian tube instead of the uterus). A tubal pregnancy is a medical emergency.
Common side effects may include:
mild stomach pain;
breast pain or tenderness;
nausea, vomiting, diarrhea;
feeling tired; or
changes in your menstrual periods.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What other drugs will affect Opcicon One-Step?
Certain other medications can make Opcicon One-Step less effective, which may result in pregnancy. Ask a doctor or pharmacist if Opcicon One-Step is safe to use if you are using any of the following medications:
seizure medication–carbamazepine, felbamate, fosphenytoin, phenobarbital, phenytoin, primidone.
This list is not complete. Other drugs may affect levonorgestrel, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
