Povidone-iodine allergy

There have been only a few reports of contact allergy to povidone-iodine, despite its widespread use. In two cases there were positive patch test reactions on days 2, 3, and 7 to povidone-iodine (5% aqueous) and iodine (0.5% in petrolatum), but negative reactions to povidone itself (34). 

Indwelling catheter kits come prepackaged with povidone iodine (Betadine) to use for cleansing the perineal skin before inserting the catheter. The nurse should assess for allergies to the medication before preparing to cleanse the perineum. Another type of skin cleanser may need to be used.
