Review: Effective relief for coughing and congestion - This maximum-powered Mucinex DM has helped me a lot when I have a cough with excessive mucus and chest congestion. I like that it is long-lasting and helps clear the airways while controlling coughing. The tablets are easy to take and it is very practical to have them at home for cold season. Good product and delivers on what it promises.
Review: Excellent - When I was a young 'un growing up, I suffered terrible with hay fever. Later on, I must have grown out of it, or at least no more problems with it. Now the allergies are back with a vengeance! Go outside for a while to do whatever and then the allergies hit. I cough, constantly clear my throat; it's a mess! After doing some research, Mucinex has great feedback. Asked the Wife if we had some Mucinex hidden somewhere. Did some looking around and found a half empty box; who knows how long we've had it. Didn't look at the expiration date, just popped one with a glass of water. Within 30 minutes, the coughing, gagging, and other bad problems disappeared. Yeah, this is the good stuff!
