An iontophoresis device may be capable of preventing the generation of gas or ions upon energization, and/or may be capable of preventing the alteration of active agent ions due to an electrode reaction. Energization from an electrode to an active agent reservoir may be performed through an ionic liquid. The ionic liquid may include an anion such as PF6-, BF4-, AlCl4-, ClO4-, a hydrogen sulfate ion, bis-trifluoro-alkyl-sulfonyl-imide, or trifluoro-methane-sulfonate, and a cation such as an imidazolium derivative, a pyridinium derivative, a piperidinium derivative, a pyrolidinium derivative, and a tetra-alkyl-ammonium derivative.
