This item was recommended by my Doctor to calm the symptoms incurred from RSV. I am not coughing through the night and my chest conjestion is getting better. I hughly recommend Mucinex fast Max cough and conjestion. I works!

I've had a nagging cough for a week, and when I take Mucinex DM it feels better within a few minutes. And, it says it's 4-hour dosing but it lasts for me for well over 4 hours.

This Walmart used to be more friendly towards us. Latinos who are almost 90% of your customers yet the new manager decides not to play Latin music anymore. Well, guess what that's a part of our culture . Shopping while singing, add your local Walmart, bring back the music.
