Emergency contraceptive pills (ECPs) are special doses of birth control pills that can be used after unprotected intercourse to prevent pregnancy. Although ECPs offer a safe and effective contraceptive option, with some notable exceptions the method has yet to be widely integrated into developing-country family planning programs. The purpose of this toolkit is to facilitate the integration of ECPs into developing-country family planning and reproductive health programs. It includes resources for ECP advocacy, assessment, service provision, and evaluation. The planning and implementation tools represent best practices and experience that will help programs move through the steps required to make ECP services routinely available through health service delivery systems. The intent of the toolkit is to share widely an array of materials developed by PATH and by other organizations as they worked in a variety of settings to incorporate ECPs into family planning services. It is hoped that by bringing together these resources in a format that facilitates their use, the toolkit can reduce duplication of efforts, redundancy, and unnecessary expense.
