How is upper respiratory tract inflammation treated?

Upper respiratory tract inflammation—commonly referred to as an upper respiratory infection (URI)—typically involves the nasal passages, sinuses, pharynx, and larynx. Most URIs are viral in origin (e.g., rhinovirus, influenza virus, SARS-CoV-2, or adenovirus), and treatment is primarily supportive and symptom-based. Antibiotics are not indicated for uncomplicated viral URIs, as they offer no benefit and contribute to antimicrobial resistance.

Supportive care includes adequate hydration, rest, and symptomatic relief: saline nasal irrigation can reduce nasal congestion; steam inhalation or humidified air may ease throat discomfort and cough; and over-the-counter analgesics such as acetaminophen or ibuprofen help manage fever, headache, and sore throat. Cough suppressants (e.g., dextromethorphan) or expectorants (e.g., guaifenesin) may be considered for bothersome cough, though evidence of efficacy is modest. Intranasal corticosteroids (e.g., fluticasone) may be beneficial in patients with concomitant allergic rhinitis or persistent nasal obstruction.

Antibiotics should be reserved for confirmed or strongly suspected bacterial complications—such as acute bacterial sinusitis (symptoms lasting >10 days without improvement, worsening after initial improvement, or severe symptoms like high fever and purulent nasal discharge for ≥3 consecutive days), acute otitis media, or streptococcal pharyngitis (confirmed by rapid antigen test or culture). In those cases, appropriate agents include amoxicillin (first-line), amoxicillin-clavulanate, or macrolides in penicillin-allergic patients.

Preventive strategies—including hand hygiene, respiratory etiquette (e.g., covering coughs), and vaccination against influenza and pneumococcus—are essential, particularly in high-risk populations such as young children, older adults, and immunocompromised individuals. Patients should be advised to seek medical evaluation if symptoms worsen or persist beyond 10–14 days, or if they develop signs of lower respiratory involvement (e.g., dyspnea, chest pain, or high fevers).
