It's okay

[This review was collected as part of a promotion.] Like you know pills are mostly bitter. The instructions are very easy to follow. It does help, and mostly does what it says. Will keep using to really see.

Great

[This review was collected as part of a promotion.] This is great for any cold or flu and taking this will knock it completely out of there if taken at the right time and there's no discomfort at all and easy storage and easy absorption

Works like a charm!

[This review was collected as part of a promotion.] This medication really did come in handy when I had a headache the other day. After a while I stopped feeling the throbbing in my head. I was able to go to sleep peacefully.

Good product

[This review was collected as part of a promotion.] The mucinex helped with my cold symptoms immediately. Definitely a must have for those sick days. The pill size was a bit too big for my preference, made it difficult to swallow

Stop the cough 😷 Mucinex

[This review was collected as part of a promotion.] When the seasonal crud hits hard reach for Mucinex. This Mucinex 12-hour multi-symptom is the only thing stopping the cough. The bi-layer extended release is a total game changer. 😷🤧🥴

I was really impressed with how well Mucinex worked for me. Within a few hours, I noticed relief from my chest congestion and was able to breathe more comfortably. It helped loosen mucus and made my cough more productive, which helped me feel better faste
