What Is the Evidence-Based Treatment for Acute Laryngitis?

Acute laryngitis (CA05.0) commonly presents with dysphonia. Acute viral laryngitis accounts for most cases and does not represent a bacterial infection — a distinction that directly determines which interventions are and are not appropriate.

Clinical Approach

The protocol details first-line management of acute laryngitis, with explicit guidance — grounded in systematic reviews and randomised trials — on which commonly considered interventions are not indicated and under what conditions certain agents may be appropriate.

The guideline strongly recommends against prescribing antibiotics for dysphonia based on systematic reviews and randomized trials that showed antibiotics to be ineffective.
Acute viral laryngitis is the cause of dysphonia in most patients and is not a bacterial infection; therefore, antibiotics would be ineffective.
Based on randomized trials showing adverse effects, corticosteroids should not be prescribed for dysphonia before laryngoscopy has been performed.
