title: Emergency contraception.
abstract: The time has come for emergency contraception. It is highly underused worldwide, and especially in the United States, where patient and physician awareness remain low. There are several highly effective, well-tolerated methods that can be used to prevent undesired pregnancy after unprotected intercourse. This article discusses these methods, their method of action, effectiveness, safety, and tolerability.
