Treatment of Laryngitis
Most laryngitis is viral and self-limited, requiring only supportive care with voice rest, hydration, and analgesics—antibiotics should not be prescribed as they provide no benefit and contribute to antibiotic resistance. 1, 2
Acute Laryngitis: First-Line Management
Conservative Measures (Primary Treatment)
- Voice rest is essential to reduce vocal fold irritation and promote healing 3, 4, 2
- Adequate hydration maintains mucosal moisture and reduces laryngeal irritation 3, 4, 2
- Analgesics or antipyretics (acetaminophen or NSAIDs) for pain or fever relief 3, 4, 2
- Avoid both loud speaking and whispering, as both strain the vocal cords 4, 2
Expected Clinical Course
- Acute viral laryngitis typically resolves within 7-10 days without specific treatment 1, 2
- Symptoms may persist for 1-3 weeks in some cases 1, 3
Medications to AVOID
Antibiotics: Do Not Prescribe
- Antibiotics are ineffective for viral laryngitis based on Cochrane systematic reviews showing no objective benefit 1, 5, 6
- Antibiotics contribute to bacterial resistance, increase healthcare costs, cause side effects (rash, diarrhea, vomiting), and may precipitate laryngeal candidiasis 1, 2
- The only exceptions are immunosuppressed patients or confirmed bacterial infections (e.g., pertussis, bacterial laryngotracheitis, laryngeal tuberculosis) 1
Systemic Corticosteroids: Avoid Routine Use
- No evidence supports routine corticosteroid use for uncomplicated laryngitis 2
- Significant adverse effects include cardiovascular disease, hypertension, osteoporosis, cataracts, impaired wound healing, infection risk, and mood disorders 2
- Exception: Pediatric croup with stridor may benefit from systemic steroids 2
When to Perform Laryngoscopy
Mandatory Laryngoscopy Timing
- Perform laryngoscopy if hoarseness persists beyond 3 months to exclude serious pathology including malignancy or vocal fold paralysis 1
- Consider laryngoscopy at 4 weeks for optimal balance between allowing spontaneous resolution and preventing diagnostic delay 3
Indications for Earlier Laryngoscopy
- Professional voice users (singers, performers, teachers) with significant work impairment require prompt evaluation 1, 3
- Suspicion of serious underlying disorder at any time, including concern for malignancy, vocal fold immobility, or intubation trauma 1
- Post-surgical or post-intubation hoarseness warrants immediate bedside laryngoscopy 1
- Signs of airway compromise require urgent evaluation to exclude epiglottitis or severe laryngeal edema 4
Diagnostic Importance
- Delays in laryngeal cancer diagnosis beyond 3 months lead to higher disease stage and worse prognosis 1
- Laryngoscopy is the primary tool for assessing laryngeal structure and function 1
Anti-Reflux Therapy: Selective Use Only
When NOT to Prescribe PPIs
- Do not prescribe PPIs empirically for hoarseness without laryngoscopic evidence of laryngitis or GERD symptoms 1, 3
- Randomized trials show no benefit of esomeprazole 40 mg twice daily versus placebo for chronic laryngeal symptoms without confirmed reflux findings 1
When to Consider Anti-Reflux Treatment
- Only prescribe PPIs if laryngoscopy demonstrates inflammatory findings: erythema, edema, redundant tissue, or surface irregularities of the vocal folds, arytenoid mucosa, or posterior commissure 1, 3
- Laryngoscopic findings predictive of PPI response include interarytenoid mucosal abnormalities and true vocal fold changes 1
PPI Adverse Effects to Consider
- Decreased calcium absorption with increased hip fracture risk in older adults 1, 3
- Vitamin B12 deficiency in dose-dependent manner 1, 3
- Iron deficiency anemia 1, 3
- Increased pancreatitis risk 1
Voice Therapy Considerations
When to Refer for Voice Therapy
- Perform diagnostic laryngoscopy before prescribing voice therapy and communicate findings to the speech-language pathologist 1
- Advocate for voice therapy when dysphonia has an etiology that may improve with behavioral intervention (e.g., primary muscle tension dysphonia) 1
Critical Pitfalls to Avoid
- Do not use colored mucus as indication for antibiotics—it does not differentiate viral from bacterial infection 4
- Do not prescribe sequential antibiotics for postinfectious cough, as this promotes resistance without benefit 4
- Do not use heartburn measurement tools to assess laryngeal symptoms, as these are not validated for dysphonia or throat symptoms 3
- Do not delay laryngoscopy beyond 3 months for persistent hoarseness, as this risks missing malignancy 1, 3
Patient Education
- Explain the viral nature of most laryngitis and expected 1-3 week resolution 3, 2
- Emphasize that antibiotics provide no benefit for viral laryngitis 3, 2
- Recommend voice conservation techniques and adequate hydration 3, 2
- Inform patients that laryngoscopy will be necessary if symptoms persist beyond 3-4 weeks to identify underlying causes 3
