Very good product.

[This review was collected as part of a promotion.] Such a good cold and Fever medicine. I have been stuffy for quite awhile and this did help me for about a full 24 hours after taking it. Longer than it says, so that's a plus!

Mucinex

[This review was collected as part of a promotion.] I think this worked pretty well! It calmed my symptoms down easily and lasted a long time! They fit well in my medicine cabinet and have the same ingredients as taking several different pills..

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!

Long lasting medicine

[This review was collected as part of a promotion.] Pretty reliable medicine and lasted all day long. The pills itself is a little large for swallowing. Definitely worth the price and the quantity in package.

Medication to keep on hand

[This review was collected as part of a promotion.] Great medication. Quickly relieves from body aches and lowers fever. I love that the package is showing the size of a medication, this way you can determine if the pill is too big for you.

12 hour Relief

[This review was collected as part of a promotion.] Got a cold no problem for this new Mucinex. This cold medicine has always been my go to, but they upped their game with this one. I felt better within 12 hours and was noticeably better within 24.
