Abstract
A fail-safe iontophoretic drug delivery apparatus and a corresponding method is provided. The apparatus includes a current generating circuit for sending a current through a patch, error detection circuitry, and a control circuit. The control circuit controls the current generating circuit. When errors are detected in the apparatus, the control circuit stops the current and disables itself.
