Film-forming composition containing an antimicrobial agent and methods

A dermatologically acceptable, film-forming composition which comprises a film-forming polymer and, as a broad spectrum antimicrobial agent, iodine which forms a complex with the film-forming polymer. The compositions when applied to skin from a fugitive solvent form a substantially water-insoluble, tack-free, flexible film which adheres to skin, releases the antimicrobial agent when the film is in contact with skin, and exhibits an elongation of at least about 150%.
