摘要

Povidone-iodine is a stable chemical complex of polyvinylpyrrolidone (povidone) and elemental iodine, and is an effective and safe disinfectant agent that is used throughout the world. Povidone-iodine has found many applications in medicine, as a surgical scrub, in surgical drapes, in preoperative and postoperative skin cleansing, and for the treatment and prevention of infections in wounds and ulcers. For these purposes, povidone-iodine has been formulated at concentrations of 7.5-10.0%. There have been a handful of reported cases of allergic contact dermatitis caused by povidone-iodine in the literature, with reactions appearing within 2 days of exposure. Indeed, iodine was contained in early patch test series (1). It is also known to cause irritant reactions.
