Prednisone can be associated with fetal growth impairment in humans. Some glucocorticoids increase oral clefting in experimental animals and might do so in humans as well.

▪ 모유수유부 약물등급(Medication and Mother’s MilK): L2

▪ 모유수유 안전 및 유해성정보 :
When administered to lactating women, small amounts of prednisone and its active metabolite prednisolone will enter milk. For maternal doses of prednisolone larger than 20 mg/day, some clinicians have recommended that mothers wait at least 4 hours before nursing. Even at 80 mg/day, however, the amount secreted in breast milk would be equivalent to less than 10% of a nursing infant`s endogenous cortisol production, and it is unlikely that such a dose would produce clinically significant effects. The American Academy of Pediatrics classified prednisone and prednisolone as compatible with breastfeeding. A 2013 report from The National Transplantation Pregnancy Registry included 124 women with transplants who safely breastfed 169 infants while taking prednisone for as long as 48months. The depot injection of high doses of other corticosteroids in joints for tenosynovitis has been reported to cause temporary reduction of milk supply.
