Review: Useful to have at hand during flu season! - This is a great product. Though I am not very sure of taking it w/o consulting a doctor first. It loosens up mucus but coughing up and removing it may not always be possible. So other medication may be required if the chest congestion persists like it did in my case. Always consult a doctor first!

Wow! I was so stuffed up, taking flu medicine and cough medicine... nothing seemed to help until mighty Mucinex came home to me from amazon. Excellent product, chased down my congestion and cleared me up quick. I highly recommend and will keep some in the house in case I need again!
