Welcome to Lactnet, Michelle!! You asked about Entex, and couldn't find
it listed in Hales.
Entex is not an antihistamine. It is a mixture of guiafenisen (a mucus
thinner--expectorant, Robitussin) and phenylpropanolamine (a
decongestant, like Sudafed). Maybe these ingredients will be listed in
Hales. Hope this helps!
