Objectives: This study was designed to demonstrate the safety and efficacy of providing medication abortion in a primary care site without routine use of pre- and postprocedure transvaginal sonography.

Methods: We performed a retrospective record review of 172 consecutive patients choosing medication abortion at our clinic. Our protocol used sonography only as needed for specific indications.
