Management of Cough and Coryza in a 3-Year-Old Child

Do not use over-the-counter cough and cold medications in this child, as they lack proven efficacy and carry serious safety risks including death in young children. 1

What NOT to Do

  • Avoid all OTC cough and cold medications containing antihistamines or decongestants in children under 6 years, as they provide no symptomatic benefit and have caused 123 fatalities (54 from decongestants, 69 from antihistamines) in children under 6 years between 1969-2006. 1

  • Do not use dextromethorphan or other cough suppressants, as they have not been established as effective for symptomatic treatment of upper respiratory tract infections in young children. 1

  • Do not use beta-agonists (like salbutamol/albuterol) for acute viral cough, as they are non-beneficial and have adverse events. 1

  • Do not prescribe antibiotics for this acute viral illness with mild symptoms, as young children with uncomplicated upper respiratory infections generally do not need antibiotics. 1

Recommended Supportive Care Approach

Provide honey as the primary treatment for this 3-year-old child, as it offers more relief for cough symptoms than no treatment, diphenhydramine, or placebo. 2, 3

Specific Supportive Measures:

  • Ensure adequate hydration to help thin secretions and prevent dehydration. 1

  • Use gentle nasal suctioning to clear nasal passages and improve breathing. 1

  • Administer acetaminophen or ibuprofen to keep the child comfortable and help with fever if present. 1

  • Maintain a supported sitting position if the child has respiratory discomfort, as this may help expand lungs. 1

When to Escalate Care

Seek immediate medical attention if:

  • Respiratory rate >50 breaths/min in this age group 1
  • Difficulty breathing, grunting, or cyanosis 1
  • Oxygen saturation <92% if measured 1
  • Not feeding well or signs of dehydration 1
  • Persistent high fever ≥39°C for 3+ consecutive days 1

Consider chest radiograph only if:

  • Tachypnea (>42 breaths/min in a 3-year-old) 4
  • Crackles, decreased breath sounds, or respiratory distress on examination 4
  • High fever with hypoxia 1

Important caveat: Do not obtain chest radiographs routinely, as up to 97% of children with recent colds show non-specific abnormalities that do not change management. 1

Follow-Up Timeline

  • Review the child if symptoms are deteriorating or not improving after 48 hours. 1

  • Most viral upper respiratory infections resolve within 1-3 weeks, with 90% of children cough-free by day 21. 1

  • If cough persists beyond 4 weeks, this becomes chronic cough requiring systematic evaluation including chest radiograph and consideration of protracted bacterial bronchitis. 1

Parent Education Points

  • Explain that this is a self-limiting viral illness expected to resolve within 1-3 weeks. 1

  • Emphasize the risks of OTC medications outweigh any potential benefits in this age group. 1

  • Teach parents to recognize warning signs requiring immediate medical attention (listed above). 1

  • Address parental anxieties directly and set realistic expectations about illness duration. 2

  • Eliminate environmental tobacco smoke exposure if present, as it exacerbates respiratory symptoms. 1, 2
