Improved quality of life associated with long-term use of guaifenesin in a patient with chronic obstructive pulmonary disease (COPD) stable chronic bronchitis: A case report

摘要

We read with interest the recent case reports in this journal on the apparent beneficial effects of long-term, high-dose guaifenesin in patients with chronic respiratory disease. This prompted us to review our own patient database as we also recommend daily guaifenesin to patients who report problems with mucociliary clearance. In our rural primary care practice, we currently have over 20 patients who have taken guaifenesin daily, for more than 3 years as an adjuvant to their prescribed medications for either chronic obstructive pulmonary disease (COPD) and/or stable chronic bronchitis. We report the long-term use of guaifenesin in one such patient with COPD, chronic bronchitis and seasonal allergies who presented with dyspnea and chronic, non-productive cough that impacted his activities of daily living.
