An iontophoretic drug delivery device includes a controller normally being in an off or low power consumption state, and a patch including electrodes, a reservoir for holding an ionizable drug for transdermal delivery to a patient and a return reservoir. The patch is removable and electrically connectable to the controller, and delivers the drug to patient when the patch is on the patient's skin and when the controller is switched from the off or low power consumption state to an operational state. This occurs when the patch is connected to the controller and a connector connects a power source to the controller or an activation means signals the controller to switch to the operational state. This feature preserves the battery of the controller.

1. An iontophoretic drug delivery device comprising:a controller having a current generating circuit, said controller having an operational state, a normally off state and being selectively switchable between the states; a power source; a patch attachable to the skin of a subject, the patch comprising at least two reservoirs respectively including an anode and a cathode, one of the reservoirs for holding an ionizable drug for transcutaneous delivery when said controller is in the operational state and said patch is attached the skin, said patch being removably, electrically connectable to said controller; a connector having one end and another end for electrically connecting said power source to said controller, and wherein when said patch is electrically connected to said controller and said connector connects said power source to said controller, said controller is switched to the operational state from the normally off state; and wherein said connector comprises a pull tab comprising a material that is an electrical insulator, said pull tab being inserted between said power source and said controller such that when said pull tab is removed said power source is electrically connected to said controller.
