Mucinex ER works quickly & ongoing RELIEF.

Great Product, helps thin mucus in throat & chest to make it easier to swallow & or clear throat & spit it out. I prefer the 600mg bilayered Extended Release tablet, bc it you need 1 or 2 tablets--taking 1 600 mg gives you more flexibility in when & how you can take it without exceeding the maximum tablets that can be taken in 24 hours. As a suggestion please check with your doctor or pharmacist if you aŕe having other symptoms such as fever &/or difficulty swallowing--you may have a chronic condition that needs other medical attention / treatment.

Does eliminate my congestion

I have used Mucinex for years. When I need congestion, I turn to Mucinex for 2 reasons. Mucinex is effective at eliminating congestion and is affordable when purchased at SamsClub.

Mucinex

I have to take mucinex almost everyday per doctors order. I'm thankful it works so good but it's so expensive at the same time. I'm just glad I do save money buying it in bulk
