Entex has been discussed on Lactnet previously. It is an
expectorant/decongestant.
There is no problem for the nursing infant. There is a slight chance of
decreased milk volume. The mother should drink extra fluids (or chicken soup!)
while taking an expectorant/decongestant anyway for her own benefit.
