This information provided for reference purposes only. Prednisone is a steroid. It is known to cause birth defects in animals in high doses. Patients taking prednisone have a higher chance of having a child with low birth weight and may have a higher risk of stillbirth, but many successful pregnancies have been reported in women receiving prednisone. Overall there is not enough data to know how severe these effects are.
Prednisone does appear in breast milk in small amounts.
The American Academy of Pediatrics feels it is acceptable to breastfeed while on prednisone.
