Abstract
An iontophoresis device including a control module and a disposable electrode module. The control module includes a flexible printed circuit board carrying the battery and other electrical components. The control module is so configured that by trimming it along one of several labeled lines, various current levels may be selected. Trimming the control module provides a simple method for varying the dosage of the drug delivered by the iontophoresis device and simultaneously provides an easily readable visual indicator of the dosage level.
