Only negligible amounts of SSZ were found to transfer into breast milk. [55] SSZ is believed to be safe during nursing, although the American Academy of Pediatrics has cited a reported case of bloody diarrhea in an infant as a reason to use caution with this drug during nursing. [56]

Both EULAR and BSR-BHPR guidelines find SSZ compatible with breastfeeding in healthy, full-term infants. [18, 19]
