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

Topical maternal application of Cloruro de benzalconio or benzethonium chloride or their presence as a preservative in pharmaceuticals would not be expected to cause any adverse effects in breastfed infants.

A study in Japan randomized 80 consecutive term patients into 4 groups who received either povidone-iodine or benzethonium chloride as a skin disinfectant before delivery and one of these for postpartum vaginal lacerations. Prepartum doses were about 7 mL and postpartum doses were about 0.5 mL of solution. Infant thyrotropin levels were elevated in the infants whose mothers received topical povidone-iodine pre- and postpartum compared to infants whose mothers received benzethonium chloride.[2]
