Yes, my hubby uses it through the PEG. If you are on Neudexta make sure you use only the expectorant version, only --the one that is just guaifenesin not the DM version (with dextromethorphan) as that is the same compound that is in Neudexta.

It seems to help my husband--has taken the extended release since diagnosis and then went to the every 4-6 hour variety in the feeding tube. (No extended release meds through feeding tube.) When the saliva and mucus began to build up again, doc added glycopyrrolate and got a handle on it again.
