Treatment for Upper Respiratory Tract Infections (URTI)
Most upper respiratory tract infections are viral in nature and should be managed with symptomatic treatment only, avoiding unnecessary antibiotics. 1
Diagnosis and Assessment
When evaluating a patient with URTI symptoms, consider:
- Duration of symptoms (bacterial infection more likely if >10 days)
- Fever pattern (high fever suggests bacterial infection)
- Presence of purulent discharge
- Specific symptoms (ear pain, facial pain, sore throat)
Signs of Bacterial Infection:
- Symptoms persisting >10-14 days
- Worsening symptoms after initial improvement
- Severe symptoms from onset (high fever, purulent discharge)
- Specific presentations suggesting bacterial etiology 1
Treatment Algorithm
1. Viral URTI (Most Common)
Symptomatic management only:
- Adequate hydration and rest
- Over-the-counter analgesics for pain/fever
- Saline nasal irrigation 1
- For dry, bothersome cough: dextromethorphan or codeine can be prescribed 2, 3
- For nasal congestion: pseudoephedrine for temporary relief 4
Important: Expectorants, mucolytics, antihistamines, and bronchodilators should NOT be prescribed in acute URTI in primary care 2
2. Bacterial URTI (Less Common)
Specific conditions requiring antibiotics:
- Streptococcal pharyngitis: Confirm with rapid strep test or throat culture before prescribing. Use penicillin or amoxicillin for 10 days 2, 1
- Bacterial sinusitis: Consider if symptoms last >10 days or worsen after initial improvement. Use amoxicillin as first-line treatment 2, 1
- Bacterial URTI with persistent purulent sputum: Amoxicillin-clavulanate 875/125 mg twice daily for 7 days 1
Alternative antibiotics:
- For penicillin allergy: Macrolides such as azithromycin (500 mg once daily for 3 days or 500 mg on day 1 followed by 250 mg daily for 4 days) 1
- For areas with high resistance: Consider levofloxacin or moxifloxacin 2
Special Populations
High-Risk Patients
Consider earlier antibiotic intervention in:
- Patients aged >65 years with acute cough and comorbidities
- Patients with cardiac failure
- Insulin-dependent diabetes mellitus
- Serious neurological disorders
- Immunocompromised patients 2, 1
Follow-up and Monitoring
- Advise patients to return if symptoms persist beyond 3 weeks 2
- Clinical effects of antibiotic treatment should be expected within 3 days 2, 1
- If no improvement after 72 hours of antibiotics, consider:
- Changing antibiotics
- Reevaluating diagnosis
- Hospital referral 1
Common Pitfalls to Avoid
Overprescribing antibiotics: URTIs are the most common reason for inappropriate antibiotic prescriptions, contributing to antibiotic resistance 5, 6
Inadequate symptom management: Failing to provide effective symptomatic relief can lead to unnecessary return visits and patient dissatisfaction
Missing bacterial infections: While most URTIs are viral, failing to identify the small percentage that are bacterial can lead to complications
Inappropriate medication use: Using expectorants, mucolytics, antihistamines, and bronchodilators is not recommended and may cause unnecessary side effects 2
Delayed intervention in high-risk patients: Lower threshold for treatment should be applied to elderly patients with comorbidities 1, 7
By following this evidence-based approach, clinicians can effectively manage URTIs while minimizing unnecessary antibiotic use and optimizing patient outcomes.
