Cough and Nasal Congestion
"I read all the information on the previous pages. The box of Mucinex D that I just purchased has a much higher mg of active ingredients than what was reviewed. Mine has 1200 mg guaifenesin and 120 mg pseudoephedrine HCI per pill. The information on the other page was regarding HALF those amounts. So be sure to take the correct dosages into account."
