Norma, << This is a monoclonal antibody, which is given by injection in one dose of 5g per Kg. It is considered to be experimental, and so there is not a whole lot of info about it. The drug company recommendation is that the mother either stops nursing or doesn't take the drug. >> I have a mom who is being given the drug too. Her physician (gastroenterologist) is quite convinced the drug is perfectly compatible w/ breastfeeding. I'm sorry I don't remember the specifics, but she and I sat down together and went over all the drug information. Tom, correct me if I'm wrong, but I'm remembering an extremely short half life, and a very large molecular weight -- something over 1000, if memory serves me. For some reason I'm remembering the 1/2 life as being something like .6 hours, but that might have been something else. (That does seem awfully short). In any case, we talked about it at great length, she talked about it w/ her GI who has worked extensively w/ the drug, and said that if it were HIS wife, he would encourage her to continue breastfeeding!!! Anyway, she also discussed it w/ one of the peds in our group, and the long and the short of it is that she will continue to breastfeed. I recommended that when she get it, she get several samples of breastmilk -- her doc is willing -- nay, EAGER -- to test the milk to see if/what amount of drug is in it at varying times after the infusion. Good luck. I hope Tom responds as well. Jan B, just back from beautiful Madison, WI -- what a pretty town -- where the people are delightfully friendly, and the butterburgers are terrific! *********************************************** The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(TM) mailer for lightning fast mail delivery.
