1. An electrotransport device for delivering a therapeutic agent comprising:

  • a power source;

    first and second electrodes and reservoirs, at least one of the reservoirs containing the therapeutic agent;

    a current generating and controlling circuit configured to output no current flow when a current signal to the current controlling circuit is low and to generate current flow when the control signal to the current controlling circuit is high;

    a current disabling circuit in communication with the current generating and controlling circuit, the current disabling circuit configured to output only a high signal or a low signal to respectively enable or disable the current generating and controlling circuit from supplying current to the electrodes, the current disabling circuit further including a circuit disabling element configured to provide an automatic, permanent and irreversible function to change the output from a high signal to a low signal and to permanently and irreversibly disable the current generating and controlling circuit from supplying current to the electrodes.
