[Access to emergency contraception: old barriers and new questions].

Purpose: to compare two strategies of access to emergency contraception: only information and information with previous delivery of this contraceptive method, and its relationship with the use of this method and the regular use of contraceptives.

Methods: from August 2004 to January 2005, 18 to 49-year-old volunteers, attended at reproductive health clinics from six Brazilian towns were recruited. The subjects were randomly distributed in a group getting information about emergency contraception (Control Group), or in a group getting information about this method and previous delivery of the contraceptive (Medicated Group).
