Letâ€™s face it; Robitussin is known as grandparentsâ€™ No. 1 cure forâ€¦wellâ€¦everything! If you have a cold: Robitussin! If you have a sore throat: Robitussin! If you have a headache: Robitussin! The liquid medicine has been the most sought after cure to all things illness since any kid today can remember. The drug is even referenced in Chris Rockâ€™s former sitcom, Everybody Hates Chris. Itâ€™s a global phenomenon in the Black community.
In actuality, the chemicals used in Robitussinâ€”Dextromethorphan HBr (cough suppressant). Guaifenesin (expectorant). Phenylephrine HCl (nasal decongestant)â€” truly do fight many of the symptoms people experience when getting sick. But while many grandparents would like to believe this remedy may be the cure to everything, Robitussin still has its limits.
