I've had a nagging cough for a week, and when I take Mucinex DM it feels better within a few minutes. And, it says it's 4-hour dosing but it lasts for me for well over 4 hours.

Why cough for longer than needed

This has been my households go-to during cold and flu season. Gets the job done, helps shorten the recovery time of those coughs that just seem to want to hang on forever. Works great!
