ObjectiveTo determine the benefits and risks of using Mexican pharmacies by better understanding the sociodemographics and medication needs of pharmacy clients in Ciudad Juárez; and to ascertain the role and expertise of pharmacy clerks and their impact on medication use.MethodsCross-sectional study of a convenience sample of 32 pharmacies in Ciudad Juárez conducted in August 2007-January 2008. Medical professionals interviewed 230 pharmacy clients and 25 pharmacy owners and clerks, and observed 152 clerk-client interactions. The cost of the most frequently-purchased medications was compared with pricing at pharmacies in El Paso, Texas, United States.ResultsOf the 311 medications purchased, the most frequent were: antibiotics (54), analgesics (49), fixed drug combinations (29), and blood pressure medications (26). Only 38% were purchased with a prescription; 62% of the prescription drugs bought without a prescription were self-prescribed. Many products purchased were of limited therapeutic value, and others could be harmful when used inappropriately. Pharmacy clerks were poorly trained and did not offer appropriate information on drug use; contraindications were never discussed. Contrary to popular perception, some generic drugs were cheaper in the United States than in Mexico. Conflicts of interest were identified that could be leading to over-medication.ConclusionsWhile the risks are evident, some uninsured, chronically-ill United States residents may benefit from access to medications previously recommended by a physician, without obtaining a new prescription. The authors suggest five steps for reducing the risks and improving pharmaceutical utilization in the border area.
