Jessica, according to the American Academy of Pediatrics the "Reported Sign or Symptom in Infant or Effect on Lactation" for prednisone is "NONE." (See table at http://www.aap.org/policy/00026t6.htm ). And Hale's indicates Zyrtec is safe also. Could this mother perhaps talk to her pediatrician to request information on the safety of these drugs while breastfeeding? This strategy has worked for me in the past when I have received calls from mothers who are told by their primary care physician to WEAN or BE SICK (the mother, that is). I know my pediatrician keeps a current copy of Hale's and perhaps this mother would be empowered to take the medication she needs if she can be reassured by her baby's doctor that the medication is safe. Another alternative is to have the mother call a pharmacist since many pharmacists are well informed about the effects of a particular drug, beyond the package insert. Is there a breastfeeding friendly hospital in your area? My guess is that the pharmacy of that hospital would have access to Hale's or perhaps "Drugs in Pregnancy and Lactation" by Gerald G. Briggs, B Pharm, Roger K. Freeman, MD and Sumner J. Yaffe, MD. Good luck with this mom.
