Take Mucinex And Feel Better Faster

Mucinex is our go to for colds, sinus, congestion, etc. It works faster than some other brands we've tried through the years. Many times, one dose is all it takes! I don't remember us taking it for more than 2 days except for the two times we had the flu.. IF Mucinex does not work, then it's time to see a doctor! So far that has not happened! . The only thing we don't like is the size of the pill when we have heavy congestion.

GREAT STUFF! IT ACTUALLY WORKS!

It's a bit pricey but IT DOES THE JOB! MOST of the issues with COPD is the mucus build-up and THIS STUFF helps break that up and clear your passages so you can breath better on top of all the other issues you have to deal with!

My father who is 94 could not clear the gunk in his lung even after antibiotic. He had a terrible cough but could not get the phlegm up still The palliative doctor then suggested Mucinex 12 hour max strength expectorant and that finally helped clear him up! So I definitely think it is great!
