Hi Rocio,

Guaifenisin (Robitussin, Duratuss-G, Humibid) are "mucolytics", work to thin
viscous mucous secretions, and should have no adverse effects on the vocal
cords. Instead, I would expect that, by thinning secretions (with the help
of plenty of hydration), these agents would ease the feeling of needing to
clear one's throat, and thus help relieve cord stress.
