Efficient and effective relief

[This review was collected as part of a promotion.] Mucinex Maximum Strengh Expectorant is the way to go for quick and efficient relief. I was pleasantly surprised overall regarding the positive effects I was able to get from this expectorant. Within a day or so I was seeing an improvement in my symptoms.

Very large pill

These were too large for me to swallow. They start dissolving almost immediately and left an awful taste on my tongue. I tried multiple times, but it would not work for me. I will have to try to the regular ones which are half the size. Wish I would have known how big they were before hand, rather than waste money.

Excellent for chest congestion

[This review was collected as part of a promotion.] Overall the Mucinex Maximum Strength Expectorant exceeded my expectations! I became ill with a seasonal cold which included chest and nasal congestion. The first day I took the product, I was on my feet in a matter of minutes! Not only does thw product work exceptionally, one tablet lasted ALL day. I highly recommend this product for anyone seeking fast relief that truly lasts. I plan to give this to my teen if he comes down with any symptoms.

Breathing Made Easier

[This review was collected as part of a promotion.] I recently tried Mucinex Maximum Strength Expectorant and I am a believer! I run into a lot of issues with my sinuses. The fact that Mucinex is able to clear up the clogs and I am able to breathe makes me extremely happy.
