Hi Penny, I would contact Hale's InfantRisk Center about this asap: www.infantrisk.com It has some info on the use of the drug during pregnancy: http://www.infantrisk.com/content/myasthenia-gravis-pregnancy The only guidance that I could find regarding use of this drug during bfing is on his the old Web Forum: http://neonatal.ttuhsc.edu/discus/messages/51/3966.html and http://neonatal.ttuhsc.edu/discus/messages/53/47833.html Also, LACTMED lists the med here: http://toxnet.nlm.nih.gov/cgi-bin/sis/search/f?./temp/~xbWqVQ:1 The docs on this case should recognize the authority of the NIH Toxnet info.
