MUCINEX helped relieve my cough, congestion, fever, and body aches quickly, and the 12-hour formula made it convenient for all-day relief.

A single medicine for all cold symptoms.”

[This review was collected as part of a promotion.] Excellent for severe colds. Relieves fever, and congestion all at once and lasts 12 hours. You don't need to take several medications - just one is enough.

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
