A member asked:

What are the possible side effects of mucinex (guaifenesin) for congestion and how well does it work?

Drink water instead: Mucinex (guaifenesin) has few side effects, but you can get the same mucus thinning effect from drinking more water. Save the money and drink more water instead.
