An iontophoretic drug delivery system including a patch and a controller. The controller and patch include electronics which ensure proper hydration of the patch. If the controller determines that the patch is sufficiently hydrated, the controller applies current to the patch for delivery of the drug through the skin of the patient.

An iontophoretic drug delivery system comprising: a controller for providing a specific current to drive an ionizable substance into the skin of a patient, a patch removably, electrically coupled to said controller, said patch including an electrode assembly, said electrode assembly including an electrode reservoir and a drug reservoir containing an active compound to be delivered to the patient, with said drug reservoir being hydratable, and a resistive network coupled to at least one of said reservoirs; and means for monitoring a voltage of the resistive network and comparing the monitored voltage with a predetermined voltage signature so that the controller will permit current to flow for delivery of the drug if the reservoirs are sufficiently hydrated and prevents current from flowing for delivery of the drug if the reservoirs are insufficiently hydrated.
