ABSTRACT OF THE DISCLOSURE Applicators for the electrophoretic and/or electro- osmotic dispensing of a medicament across the skin and into the bloodstream of a patient. Each applicator includes two electrodes in electrical contact with the skin with at least one of the electrodes being a drug reservoir, at least one battery, a flexible, non-conductive substrate having an electrically conductive coating extending to electrical contact with each electrode and to the terminals of the battery, the substrate being folded into at least two layers, and a covering for the drug reservoir. The flexible substrate and the conductive coated areas form a single, substantially flat, flexible member. The applicator can include a plurality of separate drug reservoirs each acting as an electrode. At least one battery is connected in series with the drug reservoir electrodes. The flexible substrate has opposed flat surfaces, the electrically conductive coated areas being electrically coated areas on the flat surfaces. Electrical connection between the conductive coated areas in the vicinity of each reservoir is provided by electrically conductive material extending through a single hole or a plurality of holes that extend between the opposed surfaces of the substrate.
