Guaifenesin is a substance that helps loosen and liquefy mucus, and as such is a common component of many nonprescription cold and cough remedies. It is derived from a tree bark extract called guaiacum, historically appreciated for its expectorant qualities in the Caribbean region and adopted by European explorers in the 1500's.
Guaiacum was approved for use as an expectorant by the Food and Drug Administration some 400 years later, in 1952. And 20 years ago the extract was synthesized, pressed into tablets, and named guaifenesin.
How Does Guaifenesin Work?
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, flu 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,(1) and so may relieve sinus pressure/ headache. As Dr. Sarah Myhill 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.
Here again, 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."
Guai also enjoys a popular reputation as 'the opera singer's friend.' Terming it their 'wonder drug,' singers have traditionally used guaifenesin to improve the state of their vocal folds in extremes of humidity (very dry or very humid), after flying long distances, and during mild allergies, for its ability to promote 'secondary mucosal secretion' – the thinner, lubricating mucus that occurs on the vocal folds naturally when they are healthy and well hydrated.
Patients with chronic obstructive pulmonary disease (COPD) 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 their damaged airways.
Similarly, guaifenesin can assist by thinning 'sticky' mucus to help expel inhaled particles that can exacerbate asthma symptoms.
Importantly, whether used to ease the congestion of colds, flu, or rhinosinusitis, 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.
As with many complex herbal compounds used in traditional medicine, exactly how guaifenesin encourages healthy mucus flow is not yet completely understood. But based on its long history - if taken as instructed on the package or as suggested by a pharmacist or healthcare provider - guai has at most minor side effects and is generally considered safe for use even by youngsters over 12 years of age.

Guaifenesin FA™ as Effective as Extended Release Guaifenesin 600
Dr. St. Amand has informally tested Guaifenesin FA™ (Fast Acting) with his patients and found it to be just as effective as the Guaifenesin 600mg extended release product. He attributes these positive results to the quick dissolution of the fast acting guaifenesin tablets, which facilitates timely uptake and utilization by the body.
