What is Plan B One-Step?
Plan B 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.
Plan B 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).
Plan B One-Step is a backup method of preventing pregnancy and should not be used as regular birth control.
Warnings
Do not use Plan B One-Step if you are already pregnant. Levonorgestrel will not terminate a pregnancy that has already begun (the fertilized egg has attached to the uterus).
Plan B 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.
Any person, regardless of age, can purchase Plan B One-Step right off the shelf without a prescription, ID or age requirement at all major retailers in the U.S.
Ask a doctor or pharmacist before taking this medicine if you regularly use medication for seizures, tuberculosis, or HIV/AIDS. Certain other medicines can make levonorgestrel less effective.
