For years this was the medication prescribed by our doctors. As far as I’m concerned if it’s good enough to be prescribed then it’s good enough once it’s became an OTC for me to continue using it.

Can pay for this 2 box supply at Sam's Club for the almost the price of 1 box at other stores.

Though the pills are a big, they are so effective. The pills work fast and helps you cough up the phlegm and get you on the road to feeling better.

Best medicine to help control coughs and thin mucus! Its a must for your medicine cabinet! #DoctorsTrustMucimex #MucinexDoctorAlly

If you need a medicine to help you with congestion and cough, do not hesitate to try Mucinex , it will help you

I recieved this is a vox box at the most ideal time. Absolutely worked so much better on my congestion than anything I had in my medicine cabinet.

Great to control cough especially if you don’t like to drink a liquid medicine. I usually need an expectorant.

The gold standard for any cough! My doctor and I agree the 2 OTC must haves for any cough are humidifier + these pills! Be sure to hydrate

This is a great over the counter medicine. It does what it’s supposed to. It is expensive but much needed.

This product is great, it works but made me drowsy and sleepy. No where on the box does it mention drowsy.
