Corticosteroids are commonly found in breast milk at an average concentration of 6-33 micrograms / liter. When used topically, in inhalation, intra-articular or enema: Its low absorption through the skin, nasal or bronchial mucosa, joint or colon, makes it unlikely a excretion into breast milk in significant amount. It has been published a case of decreased milk production after intra-articular injection of corticosteroids. Should you be treated for eczema or dermatitis of the nipple, choose the least potent corticosteroid, make sure to apply it just after the meal to make sure it has been absorbed before the next meal, if necessary remove excess of cream with a gauze and do not used it for more than a week. Mineralocorticoid toxicity has occurred in an infant after continuous application of a corticosteroid in the nipple.Avoid application creams, gels and other paraffin-containing products on the nipple, to avoid ingestion by the infant.
