The use of povidone-iodine in the mother near term and during breastfeeding increases breastmilk iodine levels and can cause transient hypothyroidism in breastfed infants, especially in geographic areas that are iodine deficient. Maternal exposure to povidone-iodine near term can sometimes interfere with thyroid studies done as a part of newborn screening tests. Although povidone-iodine is minimally absorbed through intact adult skin, exposure of mothers who are or will be breastfeeding to povidone-iodine should be minimized by using lower concentrations of povidone-iodine, applying it to the smallest possible surface areas of the body, shortening contact time, and avoiding repeated applications. Iodine absorption can be extensive with vaginal use; avoid douching with povidone iodine or use of iodine-containing tampons during
