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.

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.

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

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.

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

Excellent

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.

My doctor recommended I take these every day to help with mucus buildup from my Asthma and COPD. I have been taking these daily for over a year now and they have sure made a difference. I hope Sam's continues to have these in their Instant Savings because it sure helps to afford these with my limited income. I have tried other generic brands but none work as well as these.

This stuff works wonders for my husband who has serious sinus pressure issues and is prone to sinus infections. He had previously been using a similar product for sinus pressure and pain, but it didn't work nearly as well as this product. Guaifenesin for the win!

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.
