Treatment of Nasal Congestion in Infants

First-Line Treatment

• Saline nasal irrigation is recommended as the primary treatment for nasal congestion in infants, as it helps remove debris from the nasal cavity and temporarily reduces tissue edema to promote drainage, according to the American Academy of Pediatrics 1, 2
• The use of saline nasal irrigation has been shown to result in greater improvement in nasal airflow, quality of life, and total symptom score when compared with placebo in children 2
• Fewer than 1 in 15 children get a true bacterial sinus infection during or after a common cold, highlighting the importance of appropriate diagnosis and treatment 1

Medications to Avoid

• Oral decongestants and antihistamines should be avoided in children under 6 years of age due to potential toxicity and lack of proven efficacy, as recommended by the FDA's Nonprescription Drugs and Pediatric Advisory Committees 3, 4
• The FDA's guidelines are based on evidence of 54 fatalities associated with decongestants and 69 fatalities associated with antihistamines in children under 6 years 3

Second-Line Options

• If saline irrigation alone is insufficient, topical decongestants like xylometazoline may be considered for very short-term use only (no more than 3 days), with caution due to the narrow margin between therapeutic and toxic doses 4

When to Consider Medical Evaluation

• If nasal congestion persists beyond 10 days without improvement, or is accompanied by fever ≥39°C (102.2°F) for at least 3 days, or worsens after initial improvement, medical evaluation should be sought to rule out bacterial sinusitis, as recommended by the American Academy of Pediatrics 1, 5

Treatment of Nasal Congestion in Children Under 3 Years with Normal Saline

Efficacy of Saline Nasal Irrigation

• Saline irrigation has demonstrated greater improvement in nasal airflow, quality of life, and total symptom scores compared to placebo in pediatric patients, according to the American Academy of Pediatrics 6

Safety of Pharmacologic Agents

• Oral decongestants in infants and young children have been associated with serious adverse effects, including agitated psychosis, ataxia, hallucinations, and death, as reported by the American Academy of Allergy, Asthma, and Immunology 7
• The American Academy of Pediatrics recommends avoiding antihistamines as primary treatment for simple nasal congestion in children under 6 years due to lack of efficacy for congestion and sedation risks 6

Approved Medications for Children

• Intranasal corticosteroids, such as triamcinolone, mometasone, and fluticasone furoate, are approved for children aged 2 years and older for allergic rhinitis, but not for simple viral congestion, according to the American Academy of Otolaryngology-Head and Neck Surgery 8, 9

Management of Nasal Congestion in Children Under Five

First-Line Treatment and Ineffective Options

• The European Position Paper on Rhinosinusitis considers nasal saline irrigation an option for relieving symptoms of acute upper respiratory tract infections, particularly in children 10
• Gentle suctioning of the nostrils may help when the child's nose is blocked with secretions 11
• Antihistamine-decongestant-analgesic combinations show no evidence of effectiveness in young children 10
• Nasal corticosteroids are not supported by current evidence for symptomatic relief from the common cold 10
• Antibiotics are not recommended for routine use in common cold or acute purulent rhinitis, as fewer than 1 in 15 children develop true bacterial sinus infection during or after a common cold 10
• Steam/heated humidified air has no demonstrated benefits for treating the common cold 10
• Echinacea has not been shown to provide benefits for treating colds 10

Respiratory Red Flags

• Oxygen saturation <92% or cyanosis is a red flag requiring medical evaluation 11
• Respiratory rate >70 breaths/min in infants <1 year or >50 breaths/min in older children is a red flag requiring medical evaluation 11
• Difficulty breathing, grunting, or intermittent apnea requires medical evaluation 11
• Not feeding or signs of dehydration requires medical evaluation 11

Supportive Care

• Families need information on managing pyrexia, preventing dehydration, and identifying deterioration 11
• Children cared for at home should be reviewed if deteriorating or not improving after 48 hours 11

Management of Nasal Congestion in Infants (≤12 months)

Expected Clinical Course

• Viral upper‑respiratory infections in infants are typically self‑limiting, with nasal symptoms resolving within 7–10 days in the majority of cases. 12
• The nasal discharge often progresses from clear, watery secretions to a thicker, cloudy appearance; this evolution is normal and does not signify a complication. 12
• The color of nasal mucus (clear, white, yellow, or green) does not differentiate viral from bacterial infection; colored secretions are a usual feature of viral colds. 12

Supportive Home Care

• Antipyretic use: When the infant has fever and discomfort, acetaminophen may be administered for symptomatic relief, with dosing determined by the pediatrician. 13

Red‑Flag Signs Requiring Immediate Evaluation

• Respiratory distress: Respiratory rate > 70 breaths/min, audible grunting, chest wall retractions, or nasal flaring. 13
• Cyanosis: Bluish or gray discoloration of the lips or facial skin. 13
• Feeding difficulty/dehydration: Refusal or inability to take liquids, ≤ 4 wet diapers in 24 h, absence of tears when crying, or a sunken anterior fontanelle. 13
• Altered mental status: Marked lethargy, difficulty arousing, or inconsolable crying. 13
• Apnea: Observable pauses or brief cessation of breathing. 13

Follow‑Up Recommendations

• Arrange a pediatric evaluation if any red‑flag sign appears or if new or worsening symptoms develop after an initial period of improvement (e.g., new fever, increased irritability). 13
