Iodine-free disinfectant which is widely use for skin, mouth, and, obstetric disinfection. It is preferred over iodine-based disinfectants in order to avoid high iodine exposure to the child in the neonatal and breastfeeding period that would pose a higher risk for thyroid dysfunction. Because of pharmacokinetic data (high molecular weight, high capacity for serum protein-binding and poor oral or gut absorption) significant excretion into breast milk is unlikely. Used for obstetrical purposes (vaginal or C-section wounds) even during birth or in the puerperal period, has failed to cause harm neither to the newborn nor the breastfed child. Although use in the nipple may not cause troubles to the breastfed infant (except one reported case in 1989) it is not considered to be a justified practice for prevention of mastitis. Any way, it is preferred to avoid use on the nipple, at least on a long-term basis. If used, wash the nipple thoroughly before nursing.
