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.

Good product to clear congestion.

[This review was collected as part of a promotion.] This product works great. It really helped with my congestion. The only thing I wish is that it lasted a little longer. I found that it had begun to stop working before it was time for the next dose.

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.

Relief and protection

[This review was collected as part of a promotion.] The Mucinex Maximum Strength Expectorant is a great pill that really helps to clear up my congestion and get me feeling back to normal so I can make it through the day or sleep through the night. This is great that it has an immediate effect and has extended release as well so that it lasts longer and continue to help protecting me.

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.

Great Product

[This review was collected as part of a promotion.] I would say that I really liked this Mucinex Maximum Strength Expectorant a lot because I was having some chest congestion from a cold that I had and I felt it did a great job at helping thin and loosen the mucus that I had and also making me feel better. I also felt this product was great because it did seem to help me for 12 hours and I felt the tablets were very easy to take.
