Cough Management Guidelines

Introduction to Cough Management

The American Thoracic Society recommends avoiding manually assisted cough in patients with airflow obstruction, as it may be detrimental, and instead teaching huffing as an adjunct to sputum clearance, with Grade C recommendation 1, 8
The American College of Chest Physicians suggests that albuterol carries Grade D recommendation for acute or chronic cough not due to asthma, and the focus should be on treating underlying asthma with inhaled corticosteroids and bronchodilators as per asthma guidelines, not cough suppressants 1

For chronic bronchitis, the American College of Chest Physicians recommends using peripheral cough suppressants (levodropropizine, moguisteine) or central suppressants (codeine, dextromethorphan) for short-term symptomatic relief, with Grade A and B recommendations respectively 1, 2
Ipratropium bromide is the only inhaled anticholinergic recommended for cough suppression in chronic bronchitis, with Grade A recommendation 2, 3, 4
Hypertonic saline and erdosteine increase cough clearance on a short-term basis, with Grade A recommendation 1, 5

For URI-related cough, the American Academy of Family Physicians recommends avoiding both peripheral and central cough suppressants as they have limited efficacy, and instead using simple home remedies like honey and lemon, adequate hydration, and menthol lozenges 1, 6, 5
Honey and lemon mixtures are effective first-line approaches, with Grade A recommendation 6, 5
Menthol lozenges or inhalation provide short-term suppression through cold and menthol receptors, with Grade B recommendation 6

For nonproductive dry cough, the American College of Chest Physicians recommends dextromethorphan as the first-line treatment due to substantial benefit and favorable safety profile, with maximum suppression at 60 mg doses, and Grade A recommendation 6, 5
First-generation antihistamines with sedative properties are particularly helpful for nocturnal cough, with Grade B recommendation 6, 5

For idiopathic chronic cough, the British Thoracic Society recommends dextromethorphan as the non-specific antitussive of choice, with Grade A recommendation 7, 8
Baclofen and nebulized local anesthetics (lidocaine, mepivicaine) have weak evidence of benefit, with Grade C recommendation 7, 8
Low-dose morphine has recently shown helpfulness, with Grade B recommendation 7, 8

For cough not due to asthma, the American Academy of Allergy, Asthma, and Immunology recommends avoiding albuterol, with Grade D recommendation, and instead focusing on treating underlying asthma with inhaled corticosteroids and bronchodilators as per asthma guidelines, not cough suppressants 1

For COPD-related cough, the Global Initiative for Chronic Obstructive Lung Disease recommends avoiding manually assisted cough, as it may be detrimental, and instead teaching huffing as an adjunct to sputum clearance, with Grade C recommendation 1, 8, 4
Inhaled corticosteroid therapy should be considered for severe airflow obstruction or frequent exacerbations, as it reduces exacerbation rates and cough, with Grade A recommendation 4

For adult CF patients, the Cystic Fibrosis Foundation recommends using amiloride to increase cough clearance, with Grade A recommendation 1
Recombinant DNase improves spirometry but does not increase cough clearance, with Grade D recommendation 1

For pneumonia and bronchiectasis, the American Thoracic Society recommends that cough clearance is important and suppression would be undesirable, with Grade A recommendation 7, 8
Treatment should focus on the underlying infection and airway clearance rather than cough suppression, with Grade B recommendation 7, 8

The American College of Chest Physicians recommends never using albuterol for cough not due to asthma, with Grade D recommendation 1
The American Academy of Family Physicians suggests avoiding antibiotics for nonproductive cough due to viral infections, even when phlegm is present, with Grade D recommendation 6
The American College of Chest Physicians recommends avoiding codeine for URI-related cough, as it has limited efficacy despite being effective in chronic bronchitis, with Grade D recommendation 1, 2, 3
