What is the best course of treatment for a 1-year-old with a cough?

Management of Cough in a 1-Year-Old Child

For a 1-year-old with acute cough (less than 4 weeks), provide supportive care only—honey can be offered for symptom relief, but avoid all over-the-counter cough and cold medications due to lack of efficacy and serious safety risks in this age group. 1, 2

Initial Assessment and Cough Duration

• Determine if the cough is acute (< 4 weeks) or chronic (≥ 4 weeks), as this fundamentally changes your diagnostic and treatment approach 3
• For acute cough in a 1-year-old, the most likely cause is a self-limiting viral upper respiratory infection that will resolve within 1-3 weeks, though 10% may persist beyond 20-25 days 1, 4
• Assess for red flags immediately: difficulty breathing, respiratory rate >70 breaths/min, grunting, cyanosis, oxygen saturation <92%, poor feeding, or signs of dehydration—any of these require urgent medical evaluation 2

Treatment for Acute Cough (< 4 weeks)

• Honey is the only recommended treatment for symptomatic relief in children over 1 year old, as it provides more relief than diphenhydramine, placebo, or no treatment 1
• Never prescribe over-the-counter cough and cold medications in children under 2 years—these have caused 54 deaths from decongestants and 69 deaths from antihistamines in children under 6 years (1969-2006), with the majority occurring in infants 2
• Provide supportive care: ensure adequate hydration to thin secretions, use antipyretics for fever/discomfort, and gentle nasal suctioning if needed 2
• Eliminate environmental tobacco smoke exposure, which exacerbates respiratory symptoms 3, 2

When Cough Becomes Chronic (≥ 4 weeks)

• At 4 weeks duration, transition to a systematic chronic cough evaluation using pediatric-specific algorithms 3, 1
• Determine if the cough is wet/productive versus dry, as this critically guides your diagnostic approach 3, 1

For Chronic Wet/Productive Cough:

• If no specific cough pointers are present (no coughing with feeding, no digital clubbing, no failure to thrive), treat empirically for protracted bacterial bronchitis (PBB) with a 2-week course of antibiotics targeting Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis based on local antibiotic sensitivities 3, 1
• If cough resolves with antibiotics, diagnose PBB 3, 1
• If wet cough persists after 2 weeks of antibiotics, extend treatment for an additional 2 weeks 3, 1
• If wet cough persists after 4 weeks total of appropriate antibiotics, proceed to further investigations including flexible bronchoscopy with quantitative cultures and/or chest CT 3
• If specific cough pointers ARE present (coughing with feeding, digital clubbing, failure to thrive, hemoptysis), immediately pursue further investigations to assess for underlying disease such as aspiration, immunodeficiency, or structural abnormalities 3, 1

For Chronic Dry Cough:

• Consider post-viral cough, upper airway cough syndrome (post-nasal drip), or asthma if there are associated symptoms of wheeze, exercise intolerance, or nocturnal symptoms 1
• Obtain chest radiograph and spirometry (if child can cooperate) as first-line investigations 3, 1
• Do NOT empirically treat for asthma, gastroesophageal reflux disease, or upper airway cough syndrome unless other clinical features consistent with these conditions are present 3, 1
• For children >6 years with suspected asthma, consider testing for airway hyperresponsiveness 3

Critical Pitfalls to Avoid

• Never use codeine-containing medications in children due to risk of serious respiratory distress 1
• Never use an empirical "shotgun" approach treating multiple conditions simultaneously without specific clinical features supporting those diagnoses 3
• Do not routinely perform additional tests (skin prick testing, Mantoux, bronchoscopy, chest CT) unless individualized based on specific clinical findings 3
• Do not assume treatment response proves diagnosis without proper follow-up, as many coughs have favorable natural history regardless of intervention 5

Follow-Up and Reassessment

• Review the child within 48 hours if symptoms are deteriorating or not improving 2
• Address parental concerns and expectations directly, providing education about expected illness duration and signs requiring urgent attention 3, 2
• If empirical treatment is attempted based on specific clinical features, use a defined limited duration to confirm or refute the diagnosis 3
