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
