Management of Dry Cough in Pediatric Patients

Assessment and Classification

The American College of Chest Physicians recommends determining if the cough is acute (< 4 weeks) or chronic (> 4 weeks) to guide management approach 2
The American College of Chest Physicians suggests identifying if the cough is specific (with pointers to underlying disease) or non-specific (dry cough without specific indicators) 3
Evaluate for "cough pointers" that suggest specific etiologies requiring targeted treatment, such as wheezing (suggests asthma) 2, digital clubbing 4, coughing with feeding 4, or abnormal chest radiograph or spirometry 2, 3

The American Academy of Pediatrics recommends honey as first-line therapy for children over 1 year of age with acute dry cough, providing more relief than no treatment, diphenhydramine, or placebo 1
Watchful waiting with supportive care is appropriate for most cases of acute dry cough, as most are self-limiting viral infections 6, 2
For non-specific chronic dry cough, consider a 2-4 week trial of beclomethasone 400 μg/day or equivalent budesonide dose if risk factors for asthma are present 6, 2

The American College of Chest Physicians recommends avoiding over-the-counter (OTC) cough and cold medicines, as they have not been shown to effectively reduce cough severity or duration in children 1
Codeine-containing medications should be avoided due to potential serious side effects, including respiratory distress 1
Antihistamines have minimal to no efficacy for cough relief in children 1
GERD treatments should NOT be used when there are no clinical features of gastroesophageal reflux 7

For children with chronic cough (>4 weeks) with no underlying lung disease but with GI symptoms of GERD, consider treatment according to GERD-specific guidelines for 4-8 weeks 7
Re-evaluate response after treatment period 7
For children with persistent non-specific cough after 2-4 weeks, re-evaluate for emergence of specific etiological pointers 2 and consider referral to specialist if cough persists despite appropriate management 3

Evaluate and address environmental triggers, such as tobacco smoke exposure 3, air pollutants 3, and allergens 3

All children with chronic cough should be re-evaluated within 2-4 weeks 6, 2
If medications are used, they should be discontinued if no effect is observed within the expected timeframe 8
Parental education about the natural course of cough and expected resolution timeframes is essential 8
