Guaifenesin helps loosen phlegm (mucus) and thin bronchial secretions to rid the bronchial passageways of bothersome mucus and make coughs more productive. Guaifenesin works by drawing water into the bronchi-the air passages branching into our lungs. The released water both thins the mucus and lubricates the airway, facilitating the removal of cold and allergy associated mucus from the chest by coughing, and making it easier to breathe. Guaifenesin is also considered helpful for thinning postnasal drainage from the sinuses and reducing nasal congestion, and so may relieve sinus pressure/ headache. As dr. Sarah my hill comments, "whoever designed the human body needs a black mark for putting in sinuses. They are cavities in the bones of the face with only one entry and exit hole which is easily blocked by catarrh or swollen mucus membranes." when this occurs, less oxygen can enter the sinuses, promoting bacterial overgrowth and causing sinusitis. Guaifenesin can help to relieve congestion by increasing the clearance of secretions, helping with the mucus membrane's natural job of washing away invading viruses, bacteria, pollen and other potential allergens-"the first level of immune defense." patients with chronic obstructive pulmonary disease (copd) and asthma may find guaifenesin's thinning and lubricating action helpful at times when they experience particular difficulty coughing up the thick or sticky mucus that can block damaged airways. Importantly, whether used to ease the congestion of colds or rhino sinusitis, or to support healthy vocal folds, guaifenesin works best if one drinks plenty of water, as extra fluids increase the flow of water and mucus.
