Yesterday we were going over some pharm studies and one really shocked me. The conclusion was that Robitussin is no more effective than a placebo. As it turns out, there were several studies conducted proving that, while only Weyth's (maker of Robitussin) studies had shown its effectiveness. And it not only Robitussin, most cough syrups are worthless.
