What is the recommended treatment for rhinovirus infection?

Treatment of Rhinovirus Infection

Rhinovirus infection should be managed with symptomatic treatment only—antibiotics are not indicated and no specific antiviral therapy is recommended for routine clinical use. 1

Understanding Rhinovirus Infection

• Rhinovirus is a self-limiting viral illness characterized by nasal congestion, rhinorrhea, sneezing, sore throat, and cough, typically peaking within 3 days and resolving within 10-14 days 1
• The illness is caused primarily by the host inflammatory response rather than direct viral damage to the nasal epithelium 2
• No effective antiviral therapies have been approved for prevention or treatment of rhinovirus infection despite ongoing research 3, 4

First-Line Treatment: Non-Pharmacological Measures

Start with simple, evidence-based interventions that provide meaningful symptom relief:

• Nasal saline irrigation is recommended as first-line therapy to relieve congestion and facilitate clearance of nasal secretions 1
• Adequate hydration helps thin secretions and provides symptomatic benefit 1
• Environmental humidification can alleviate mucosal dryness 1
• Adequate rest supports recovery 1

Pharmacological Symptomatic Treatment

For pain, fever, and discomfort:

• Acetaminophen or NSAIDs (ibuprofen) are recommended for relief of pain and fever 1
• These agents address the inflammatory response that drives rhinovirus symptoms 2

For nasal congestion:

• Oral decongestants (pseudoephedrine-containing products) can provide symptomatic relief, but use with caution in patients with hypertension or anxiety 1
• First-generation antihistamine/decongestant combinations (sustained-release pseudoephedrine with brompheniramine) have demonstrated efficacy in reducing cough and other symptoms 1
• Topical nasal decongestants may be used for short-term relief but must be limited to 3-5 days maximum to prevent rebound congestion (rhinitis medicamentosa) 1

Agents with limited or no benefit:

• Newer non-sedating antihistamines are relatively ineffective for common cold symptoms 1
• Guaifenesin and dextromethorphan lack evidence of clinical efficacy 1

What NOT to Do

Antibiotics are contraindicated for uncomplicated rhinovirus infection:

• Antibiotics provide no benefit for viral illness and do not relieve symptoms 1
• Unnecessary antibiotic use increases treatment costs, exposes patients to adverse events, and contributes to antimicrobial resistance 1
• Only consider antibiotics if clear evidence of secondary bacterial infection develops (symptoms persisting >7-10 days without improvement, worsening after initial improvement, or severe symptoms with fever >39°C and purulent discharge) 1, 5

Special Populations: Pediatric Considerations

In children, treatment approach differs significantly:

• Avoid over-the-counter cough and cold medications in children under 2 years due to lack of efficacy and potential for serious toxicity 6
• Topical decongestants should not be used in children under 1 year due to narrow therapeutic window and cardiovascular/CNS risks 6
• Herbal medicines (BNO1016 tablets, Pelargonium sidoides drops, Myrtol capsules) have shown benefit in pediatric post-viral rhinosinusitis without significant adverse events 6
• High-volume nasal saline irrigation is more effective than low-volume rinsing for purulent rhinorrhea and post-nasal drip in children 6

When to Reassess for Bacterial Superinfection

Monitor for these specific criteria that suggest bacterial rhinosinusitis requiring antibiotics:

• Persistent symptoms for ≥7-10 days without any improvement 5
• "Double sickening" phenomenon—worsening of symptoms after initial improvement within the first 10 days 5
• Severe symptoms (fever >39°C, purulent nasal discharge, facial pain) for at least 3 consecutive days 5

Red Flags Requiring Immediate Evaluation

• Periorbital edema or diplopia suggesting orbital complications 5
• Severe headache or altered mental status 5
• Respiratory distress or persistent high fever despite treatment 6

Common Pitfalls to Avoid

• Do not prescribe antibiotics for symptoms lasting less than 7 days—this is almost certainly viral 5
• Do not underutilize simple measures like saline irrigation and adequate hydration, which provide significant relief 1
• Do not use topical decongestants beyond 5 days to avoid rebound congestion 1
• Do not order routine imaging for uncomplicated cases, as it has high false positive and false negative rates 5
