Works really well. No side effects either. Lasts a fair amount of time too. Overall, we can't do without it. A

i use this everyday, it really helps my breathing. i only wish it was less expensive. thank you Walmart for selling the 120 dose Musinex size.

keeps excessive lung mucus from copd under control

I love this this stuff! Relieves my confession and promotes drainage.

very good product works great

I use mucinex all the time to releave congestion and sinus doctor recommended

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.

As per my dr. it is great for daily usage.

i use this for sinus headache relief Ive always wondered why they don't advertise it this way as well as chest congestion. Its the only thing that breaks my sinus headaches.

I am happy with the product, but I was cheated out of the “Instant Savings” price when I purchased the Mucinrx. I met all requirements to receive the discount, but I was charged full price. I have not been able to get the $6+ returned to me. I expect better from Sam’s Club.
