I've been using this product for years, as needed, especially at the height of allergy season when allergy meds aren't enough.

I have COPD and take Mucinex every day, can't live without it. Keeps the mucus thinned so I can breathe better.

[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.

[This review was collected as part of a promotion.] The change of seasons has really did a number on me. My chest was very congested and I was seeking immediate relief. Mucinex is an amazing product. I started feeling relief once I took it. It did take some time for me to get better, but Mucinex definitely made it a little easier.

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.

[This review was collected as part of a promotion.] I liked this product, but do not see myself buying it. When I researched it online, it seems to be very expensive and I don't feel that it is worth the cost. It did help and make me feel better-but this was a temporary fix to help with something that needed to run its course.

[This review was collected as part of a promotion.] It really helped clear me up and started working within about 30 minutes. It also worked for a long period of time. I’d say the effects probably lasted at least 12 hours, just as advertised. I definitely recommend.

[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.

[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.

[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.
