Applicators for the electrophoretic and/or electro-osmostic 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, a cover adhesively secured to the applicator, and a release liner covering and protecting the drug reservoir or reservoirs until use.
