Levonorgestrel is an emergency contraceptive that is used to prevent pregnancy after unprotected sex or after failure of another birth control method. It works by preventing a woman's egg from fully developing. It may also prevent the attachment of the woman's egg to the wall of the uterus (womb).

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective. This medicine should not be used as a regular method of birth control. Discuss your options for birth control with your doctor.

Plan B One-Step® is available as an over-the-counter medicine for any woman of childbearing potential.

WinRho SDF is a sterilized solution made from human blood. Rh is a substance that most people have in their blood (Rh positive) but some people don't (Rh negative). A person who is Rh negative can be exposed to Rh positive blood through a mismatched blood transfusion or during pregnancy when the baby has the opposite blood type. When this exposure happens, the Rh negative blood will respond by making antibodies that will try to destroy the Rh positive blood cells. This can cause medical problems such as anemia (low red blood cells), kidney failure, or shock.

WinRho SDF is used to prevent an immune response to Rh positive blood in people with an Rh negative blood type. This medicine may also be used in the treatment of immune thrombocytopenic purpura (ITP).

WinRho SDF may also be used for purposes not listed in this medication guide.
