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.

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!

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.

We highly recommend!!!! It works very well.

Good price

Such a value

This product works. I like being able to get from Sam’s in a large package.

We use mucinex forallergy or colds in winter. Good product and we re-order several times. Good deal on price.

This stuff really works - an hour after I took it I sneezed and it was almost like a demon was being chased exorcised out of my nose. I’ve never been so clear

My doctor recommended that I take Mucinex every day to help control congestion, as I have major lung/breathing issues. Mucinex helps keep my sinuses clear.
