Thanks to those who have responded to my post about this. However, I am still not clear on something: I realize that the drug itself is ok as far as breastfeeding. However, according to Tom Hale's book ('95 ed.), "Breastfeeding in women positive for herpetic infections is problematic due to possible transmission of virus to infant." This mom is in the midst of an outbreak. So I am assuming this is why she was told to pump and dump. When I talked with her, we both concurred that it sounded like the meds was ok, but the fact that the virus is active is what makes the bfing not ok right now. somehow she is thinking that by Friday is will be ok to resume the bfing(this was Monday that she called me). I think it will have been a week on the meds by then. Can anyone enlighten me more on this?? She sure would like to resume bfing ASAP. I am not assuming that her doc knows anything valid about bfing in this situation. TIA, Ellen Vegh, LLLL, Pittsburgh, PA
