Is Carbamide Peroxide Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Carbamide Peroxide? Is Carbamide Peroxide safe for nursing mother and child? Does Carbamide Peroxide extracts into breast milk? Does Carbamide Peroxide has any long term or short term side effects on infants? Can Carbamide Peroxide influence milk supply or can Carbamide Peroxide decrease milk supply in lactating mothers?

Hydrogen peroxide and urea in equimolecular proportions.It acts by releasing hydrogen peroxide and oxygen in contact with moist surfaces.It is used as a tooth whitener, for the topical treatment of infections (skin and mucous membranes) and an ear wax softener. Since the last update we have not found published data about its excretion in breast milk. As it is a product which acts locally, the absorption of hydrogen peroxide is zero or minimal since it is metabolized by the peroxides and catalase of the tissues. Furthermore, hydrogen peroxide and urea are natural components of the body and even breast milk (Al-Kerwi 2005, Ross 1985, Atkinson 1980).

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.
