Perfect for Cold & Flu Season

[This review was collected as part of a promotion.] Great product product for cold and flu season! Medium size pill easy to swallow! No aftertaste or smell I like how it comes in a flat size box so it's easy to store.

Great cold relief

[This review was collected as part of a promotion.] My husband had a summer cold and was able to test this out for me! You know a man cold is the worst 😉 He had significant relief from his symptoms using this medicine and would use again!

Works

[This review was collected as part of a promotion.] I reach for mucinex when I have a stubborn cold and especially congestion. This clears our that stuffy, drippy feeling quickly. I wish the pills were smaller but beggars can't be choosers.

It effectively alleviates discomfort.

[This review was collected as part of a promotion.] Mucinex is very well formulated for fever and cold. A small pill that can be taken as miraculous, with a small dose we will be very relaxed and having the discomfort and bad reaction.

It's awesome

[This review was collected as part of a promotion.] Simple ingredients! It's helps relieve symptoms almost immediately! I like that ita not something that has to be taken every 4-6 hours, it actually lasts 12 hours!
