1. A method for administering an effective amount of a therapeutic agent to a patient in need of such treatment by electrotransport comprising:
- selecting an effective dosage and delivery rate of at least one therapeutic agent for a patient;
providing an electrotransport controller for delivering a pre-selected current output, the controller including a coupler for attaching and communicating to a reservoir containing a therapeutic agent;
selecting a reservoir from a family of reservoirs, each reservoir having at least a predetermined quantity of a therapeutic agent sufficient to achieve the effective dosage of the agent wherein each of the reservoirs has body contacting surface area different from the body contacting surface area of another reservoir in the family, said reservoirs each having a coupler for communicatively attaching to said controller and an electrode;
coupling the selected reservoir to the controller so that said output is in electrical contact with the electrode of the selected reservoir so that the reservoir is communicatively attached to said controller to provide an electrotransport delivery system;
placing the body contacting surface area of the selected reservoir in electrical contact with the skin of the patient to provide the selected effective dosage and delivery rate for the patient; and
activating the electrotransport delivery system to administer the therapeutic agent to the patient through the skin surface.

Abstract
A reservoir and a family of reservoirs are provided which are designed to be used with a single controller to provide a wide range of therapeutic drug delivering regimens while maintaining many of the same reservoir configurations and drug formulations. A method of making a reservoir and a family of reservoirs and incorporating them into an electrotransport system is disclosed.
