What is the management for upper respiratory tract infections?

Management of Upper Respiratory Tract Infections

Upper respiratory tract infections (URTIs) should be managed primarily with symptomatic treatment, with antibiotics reserved only for specific clinical scenarios suggesting bacterial infection. 1, 2

Diagnosis and Classification

• URTIs include the common cold, rhinosinusitis, pharyngitis, and acute otitis media, which are predominantly viral in origin 2
• Bacterial etiology should be suspected if symptoms persist >10 days, fever >39°C (102.2°F) is present, or symptoms worsen after initial improvement (double sickening) 1, 2

First-Line Management for Most URTIs

• Symptomatic treatment with analgesics for pain and antipyretics for fever is recommended for most uncomplicated URTIs 1, 2
• Saline nasal irrigation, topical or systemic decongestants, and intranasal corticosteroids may provide symptom relief 3
• Combination antihistamine-analgesic-decongestant products may provide symptom relief for approximately 25% of patients 3
• Treatment should be initiated early to reduce symptom severity and viral transmission 4

Antibiotic Use Guidelines

• Antibiotics are not recommended for viral URTIs as they will not prevent progression to lower respiratory tract infections 1
• For acute rhinosinusitis, antibiotics should be reserved for:
  • Patients with persistent symptoms for more than 10 days 1, 5
  • Patients with severe symptoms including high fever with purulent nasal discharge or facial pain for at least 3 consecutive days 1
  • Patients with worsening symptoms following initial improvement of a typical viral illness 1
• When indicated for bacterial upper respiratory infections, amoxicillin is the drug of choice for susceptible (β-lactamase–negative) isolates of Streptococcus species, S. pneumoniae, Staphylococcus spp., or H. influenzae 6, 7
• Treatment with antibiotics should be continued for a minimum of 48 to 72 hours beyond symptom resolution 6

Specific URTI Management

Acute Pharyngitis

• Antibiotics for streptococcal pharyngitis should be prescribed only if test or culture results are positive 2, 5
• Penicillin V given in two daily doses is the treatment of choice for confirmed streptococcal infection 7

Acute Otitis Media

• Antibiotics are indicated for:
  • Children younger than 6 months
  • Children ages 6 to 23 months with bilateral AOM
  • Children older than 2 years with bilateral AOM and otorrhea
  • High-risk patients 2
• Amoxicillin is the drug of choice in regions with low penicillin resistance rates for S. pneumoniae 7
• Amoxicillin/clavulanate provides better coverage for treatment failures due to beta-lactamase producing H. influenzae and M. catarrhalis 7

Common Pitfalls to Avoid

• Overuse of antibiotics for viral URTIs, which provides no benefit and increases risk of adverse effects and antimicrobial resistance 3, 5
• Failure to recognize when a viral URTI has progressed to bacterial infection requiring different management 3
• Inappropriate use of homeopathic substances, including elderberry, which are not recommended for prevention or treatment of respiratory tract infections 1
• Neglecting proven supportive measures while relying on unproven therapies 3

Emerging Approaches

• Mucoadhesive gel nasal sprays may be beneficial for early intervention by creating a barrier that can trap virus particles, preventing invasion of the mucosa 4
• Judicious use of antibiotics based on accurate diagnosis of bacterial and non-bacterial conditions is essential to reduce antibiotic resistance 8
