Mucinex is great. I use it all the time and it's great that I could get the hundred count package at a reasonable price and I was surprised because I actually got 120 count instead of just the 100 but it's a great value and I'll continue to buy.

I live in the Allergy Capital of the world....Florida. Without my 12 hour Mucinex the congestion would be intolerable. Fortunately Mucinex works on runny noses, sneezing and hacking coughs .
