1. A system for iontophoretic transdermal delivery of one or more therapeutic agents into a user'"'"'s skin, comprising:

  • a first end comprising a first reservoir adapted to contain one or more therapeutic agents;

    a second end comprising a second reservoir adapted to contain one or more therapeutic agents;

    the first and second reservoirs each comprising;

    a reservoir pad adapted to absorb the therapeutic agents to be delivered to the user; and

    a foam reservoir gasket adapted to help contain the therapeutic agents contained in the reservoir pad;

    a battery for generating electric current, the battery positioned between the first and second reservoirs and comprising a bottom terminal directed toward a bottom surface of the system and a top terminal directed toward a top surface of the system;

    a first substantially flat, substantially straight electrode extending in a first direction from the battery, the first electrode comprising a first end that is electrically coupled to the top terminal of the battery and comprising a second end that is electrically coupled to the one or more therapeutic agents contained in the reservoir pad of the first reservoir, the first electrode operable to conduct electric current between the battery and the first reservoir to promote iontophoretic transdermal delivery of the therapeutic agents contained in the first reservoir into the user'"'"'s skin; and

    a second substantially flat, substantially straight electrode extending in a second direction from the battery, the second electrode comprising a first end that is electrically coupled to the bottom terminal of the battery and comprising a second end that is electrically coupled to the one or more therapeutic agents contained in the reservoir pad of the second reservoir, the second electrode operable to conduct electric current between the battery and the second reservoir to promote iontophoretic transdermal delivery of the therapeutic agents contained in the second reservoir into the user'"'"'s skin;

    the first and second electrodes and the battery positioned along a substantially straight line between the first end and the second end;

    the first and second electrodes lying in substantially the same plane.
