Treatment of Nasal Congestion and Runny Nose in Children

Age-Based Treatment Algorithm

For children over 12 years, the American Academy of Pediatrics recommends oral pseudoephedrine 60mg every 4-6 hours as needed for symptomatic relief of nasal congestion, with screening for contraindications such as hypertension, glaucoma, and urinary retention 1, 4
The American Academy of Pediatrics advises against using all over-the-counter cough and cold medications in children under 6 years due to documented fatalities, and instead recommends supportive care with reassurance, teaching nose-blowing, and use of saline nasal sprays 1, 2

The American Academy of Otolaryngology-Head and Neck Surgery warns that rhinitis medicamentosa (rebound congestion) can develop as early as day 3 of regular topical decongestant use, making it essential to limit use to 3-5 days maximum 1, 4

The American Academy of Pediatrics states that antihistamine-decongestant combinations provide no benefit over decongestants alone for viral upper respiratory infections and should not be used 1
The Journal of Allergy and Clinical Immunology notes that intranasal corticosteroids are the most effective medication class for controlling symptoms of allergic rhinitis, and should be used at the lowest effective dose in children 4

The American Academy of Pediatrics recommends considering bacterial sinusitis only when a persistent pattern of runny nose or daytime cough for ≥10 days without improvement, a severe pattern of fever ≥39°C (102.2°F) for ≥3 consecutive days with thick, colored nasal discharge, or a worsening pattern of initial improvement followed by new-onset fever ≥38°C (100.4°F) or substantial increase in symptoms is present 2, 3, 6

The American Academy of Pediatrics advises against prescribing combination antihistamine-decongestant products for viral infections, as they add cost, side effects, and no benefit, and against using topical decongestants beyond 3-5 days due to rebound congestion risk 1, 4
The Journal of Allergy and Clinical Immunology notes that oral decongestant side effects such as insomnia, loss of appetite, irritability, and palpitations should be monitored 1, 4
