Works ok but not great

It works okay to calm a cough but I don't find it helps much for chest congestion.

Mucinex

The product works great for colds and allergies. Having to show ID to buy 1 box is silly.

ddm

the mucinex works great. but I prefer member marks brand. it works the same-but price is so much better. only reason I purchased the mucinex is because you didn't have the member marks available.

Great Over the Counter Medication

Works great for flu and chest congestion. The price. Is better than any retail store for me amount you get. Only need to take 1 capsule every t2 hours.

Feeling "Normal" Again

I bought this a month ago and I'm so glad I did! I felt horrible with cough and congestion. So much phlegm. After taking my first Mucinex, I felt so much better! Cough was gone. Phlegm was gone. I was sick for a week and Mucinex was my lifesaver (because life must go on, even in sickness). Definitely keeping some on-hand from now on! "Thank you Mucinex!"

Mucinex DM Relieves Cough & Congestion Fast

Mucinex DM is the first thing we reach for when we feel congested & start coughing. We keep it in our medicine cabinet at all times. If we can start taking Mucinex DM as soon as our symptoms start it seems to shorten the duration of our cough & congestion. It works faster & better than any non-prescription medication we have tried. I like that if we do happen to run out we can get it shipped from Sam’s & usually get it the next day.

Tampering?

If this is the order that was shipped to me, the box of Mucinex appeared to have been opened, and some of the tablets’ bubble seals were perforated. If the package looked like that in the store, I wouldn’t have bought it. Because it came from the warehouse shipped as it was, I went ahead and used it. If I EVER get another pharmaceutical product in that condition, I will walk it into customer service at my Sam’s Club and request a replacement or refund.

Great Deal on Expectorants

The product was a great cost savings from what I normally see with these meds.

Love that this comes in bulk

My whole family got Covid. This had enough doses to get us all through. It is a very effective product.
