Is N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide? Is N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide safe for nursing mother and child? Does N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide extracts into breast milk? Does N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide has any long term or short term side effects on infants? Can N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide influence milk supply or can N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide decrease milk supply in lactating mothers?

Be cautious with those neonates suffering of hyperbilirrubinemia or G-6-P-D deficiency. Not commercially available in SpainBe aware of the possibility of false negative results of bacterial cultures when the mother is on antibiotics.

With healthy, fullterm infants it appears acceptable to use N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide during breastfeeding after the newborn period.[1][2] Until further data are accumulated, alternate agents should probably be used in jaundiced, ill, stressed or premature infants, because of the risk of bilirubin displacement and kernicterus. N(sup 1)-(3,4-Dimethyl-5-isoxazolyl)sulfanilamide should be avoided while breastfeeding a glucose-6-phosphate dehydrogenase (G6PD) deficient infant.
