A short-term action Sulfonamide which is similar to Sulfathiazole (see specific info) that is locally used on vagina, eyes and skin. At latest update relevant published data were not found on excretion into breast milk. Because of the small dose used and poor absorption into plasma of most topical preparations for dermatological and ophthalmological issues, it is unlikely a significant excretion into breast milk. As with other sulfonamides, caution is recommended when using it on preterm infants and newborns with hyperbilirubinemia. Avoid it on patients affected with deficit of Glucose 6-Phosphate Dehydrogenase (6-GPD). Monitor the appearance of jaundice in the infant.
