Drug Levels and Effects
Summary of Use during Lactation
Carbamide (urea) peroxide has not been studied during breastfeeding. It is unlikely that carbamide peroxide found in ear drops or teeth whiteners is absorbed into the bloodstream. However, if any carbamide peroxide were absorbed, it would be broken down to urea and hydrogen peroxide, both of which are found normally in human milk.[1,2] If carbamide peroxide is used by the mother according to directions, it is not a reason to discontinue breastfeeding and no special precautions are required.
