title: Emergency contraception, a method whose time has come: an update.
abstract: Unplanned pregnancy is a major public health problem in the United States. Emergency contraception has the potential to significantly decrease the incidence. The Yuzpe regimen is highly effective but woefully underutilized. Mechanisms of action of hormonal emergency contraception will be discussed as well as appropriate indications for use, patient counseling issues, and future methods.
