Great for Nighttime. No Need To Get Up For Dose
This product works great for me. Eliminates mucus from colds, flu, and allergies. By day, I use a 4-6 hr product but this 12 hr variety is great for overnight.

Works great for chest congestion
Mucinex works really well at breaking up the phlegm in your chest. I didn’t really need it so much for my nose. I use a saline wash for that.

Works well
Takes a bit to get use to, but only thing I’ve found to help for overnight dry mouth. The price of dry mouth products is ridiculous, which is reason for 4 stars

Controls mucus drainage well without side effects.
I've been using Mucinex for the past 6 months. It has been controlling mucus drainage very well. I have not experienced any abnormal side effects.
