Attack your congestion

CHreviews April 30, 2026

Mucinex time-release guaifenesin tablets are amazing! The guaifenesin ingredient thins mucus and so relieves your sinus and chest congestion. This particular product only has 600 mg so I take 2 if my congestion is really bad. There is also another formulation with 1200 mg. And there are cheaper off-brand versions that work just as well. Just make sure they actually are identical.

Mucinex Works for Upper Respiratory Film and COPD

Victoria May 31, 2026

I have COPD and I have alot of phlegm in my lungs and Upper Respiratory System. Without Mucinex I would suffer every single Day. Mucinex (with 8-12 oz of Water) breaks up Phlegm and Loosens it so it is a product that I have counted on for Decades. I highly recommend anyone with COPD who has issues with Phlegm production to buy the product and drink a Bottle of Water with the Pillow. Mucinex (with water) breaks up the phlegm so that it does not Congest your Lungs and Upper Respiratory System. I take a Mucinex with a Bottle of Water about 30 Minutes before my Bedtime because without it I will not have a restful sleep. HIGHLY RECOMMEND. Have used it for years with Zero side effects. Thank you Mucinex!

Because of my upper respiratory issues, this Mucinex was recommended by my respiratory surgeon. And I tell you, it has truly been a Godsend! Every morning, the mucus is coming up and I'm able to get rid of it, thank God!

Mucinex helps get rid of chest congestion

rmbudrose303 January 11, 2014

Mucinex 600mg Extended-Release tablets help thin mucus so you can cough it up. I've used it several times and it has worked as expected. You feel much better when you can get rid of the mucus. I had no side-effects when I used this product. I would recommend this product to friends and family.

While the Mucinex has eased my cough, it is not completely relieved. I'm waiting to see when I finish the box if my cough goes away.

Not Perfect

Rita January 23, 2026

There's a reason why they are less expensive than their competitors. They do run true to size and they are very absorbent. Every now %26 then, I run across something wrong in the manufacturing. The last bag I had, I had to throw a couple away because there were bare spots in the padding.
