PROBLEM TO BE SOLVED: To provide a device and a method for delivering therapeutic agents through the skin by electrotransport which is in compliance with established standard of safety for therapeutic delivery and improved efficiency and reliability. SOLUTION: An electrotransport device includes electrodes 30, 32 for coming into contact with the skin 34, a power source 22 for generating electrical current for delivering the agent, a current generating and controlling means 24 and a suspending means for permanently and irreversibly suspending the current. The suspending means may include a timer means 66, a counter means, or a body parameter sensor and limit comparator to effect permanent suspension. The suspending means may be a permanent transition to a disabled logic state, a permanent discharge of a power supply source, or a permanent diversion of electrotransport current from the electrodes, or a combination of the above.
