What is EContra EZ?
Levonorgestrel is a female hormone that can cause changes in your cervix, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
EContra EZ may also be used for purposes not listed in this medication guide.
This medicine 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
You should not use levonorgestrel if you are allergic to it.
Do not use this medicine if you are already pregnant. EContra EZ will not terminate a pregnancy that has already begun (the fertilized egg has attached to the uterus).
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.
EContra EZ 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.
EContra EZ is not approved for use by anyone younger than 17 years old.
How should I take EContra EZ?
Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
EContra EZ 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 this medicine. Do not take a second dose without first asking your doctor.
Visit your doctor within 3 weeks after taking EContra EZ. 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. EContra EZ 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 EContra EZ is used as a single dose, it does not have a daily dosing schedule.
What happens if I overdose?
Because this medicine 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 EContra EZ?
