How guaifenesin addresses mucus

Guaifenesin is an expectorant that helps address bothersome mucus, a cause of chest congestion and cough

Too thick or bothersome mucus can:

  • Obstruct small airways
  • Cause coughs by stimulating the cough reflex in the upper respiratory tract
  • Lead to secondary infections by encouraging bacterial colonization

Guaifenesin is an active ingredient in MUCINEX® products that works to:

  • Thin and loosen excess mucus to make it easier to cough up
  • Make coughs more productive
