Move over Robitussin

As a retired pediatric nurse I consider Mucinex one of the most effective OTC medications on the market for cough and congestion, I've never used the generic so I can't compare. But used as directed the results are incomparable, and I am of the Robitussin generation.

Mucinex Cough %26 Chest

Best OTC for chest congestion! I keep this and Mucinex sinus in my cabinet year round. I've been remodeling two homes for years and since a child, dust has never been my friend. Then there's winter months that brings on cold and flu season. Nothing OTC works faster than Mucinex for me and my husband. I recently learned that one of my adult children feels the same and only uses Mucinex also
