I am a breastfeeding mother and i want to know if it is safe to use 4,4-Diaminodifenylsulfon? Is 4,4-Diaminodifenylsulfon safe for nursing mother and child? Does 4,4-Diaminodifenylsulfon extracts into breast milk? Does 4,4-Diaminodifenylsulfon has any long term or short term side effects on infants? Can 4,4-Diaminodifenylsulfon influence milk supply or can 4,4-Diaminodifenylsulfon decrease milk supply in lactating mothers?

One case of hemolytic anemia has been described. Check-up for development of jaundice in the infant. Avoid its use in patients affected of G-6-PD deficiency. American Academy of Pediatrics: Maternal Medication Usually Compatible With Breastfeeding.

4,4-Diaminodifenylsulfon can be used during breastfeeding; however, hemolytic anemia might occur, especially in newborn infants and in those with glucose-6-phosphate dehydrogenase (G6PD) deficiency. The time of greatest risk for hemolysis in fullterm newborns without G6PD deficiency might be as short as 8 days after birth.[1] One source states that use of 4,4-Diaminodifenylsulfon in the treatment of leprosy is advantageous because it kills the organisms in breastmilk.[2] Monitor the infant for signs of hemolysis, especially in newborn or premature breastfed infants. Topical 4,4-Diaminodifenylsulfon gel used to treat acne has not been studied during breastfeeding. According to the manufacturer, topical 4,4-Diaminodifenylsulfon gel results in a blood level of 1% that of a 100 mg oral dose. It is unlikely that the topical gel would affect the breastfed infant, but the manufacturer states that it should not be used during nursing. Until more data are available, an alternative topical agent might be preferred.

A case of mild hemolytic anemia occurred in a 41-day-old breastfed infant whose mother was taking 4,4-Diaminodifenylsulfon 50 mg daily. The hemolysis was probably caused by 4,4-Diaminodifenylsulfon in milk.[3] A woman with leprosy took 4,4-Diaminodifenylsulfon, clofazimine and rifampin during pregnancy and breastfeeding. Her infant developed skin discoloration attributed to clofazimine which reversed 3 months after cessation of breastfeeding.[5]
