The National Drug File (NDF) is produced by the U.S. Department of Veterans Affairs, Veterans Health Administration (VHA). NDF is a centrally maintained electronic drug list used by the VHA hospitals and clinics. Facilities use the NDF to check drug interactions, to manage orders, and to send outpatient prescriptions to regional automated mail-out pharmacies. NDF includes information on clinical drugs, drug classes, ingredients and National Drug Code (NDC) Directory codes.
