Medication-Induced Hoarseness

Primary Medication Categories

• The American Academy of Otolaryngology-Head and Neck Surgery identifies seven major medication classes that cause hoarseness through distinct mechanisms: inhaled corticosteroids, ACE inhibitors, anticoagulants, bisphosphonates, anticholinergics/antihistamines/diuretics, sex hormones, and antipsychotics 1, 2
• Inhaled corticosteroids are the most common medication-related cause of hoarseness in patients with asthma or COPD, producing dose-dependent mucosal irritation and fungal laryngitis 1, 2
• ACE inhibitors cause hoarseness through chronic cough mechanism rather than direct laryngeal effects 1, 2
• Anticoagulants cause hoarseness via vocal fold hematoma formation 1, 2
• Anticholinergics, antihistamines, and diuretics produce hoarseness through drying effects on laryngeal mucosa 1, 2
• Bisphosphonates cause chemical laryngitis as the mechanism of voice change 1, 2
• Sex hormones alter sex hormone production/utilization, leading to voice changes 1, 2
• Antipsychotics cause hoarseness through laryngeal dystonia 1, 2

Critical Clinical Considerations for High-Risk Patients

• Patients using inhaled corticosteroids for asthma/COPD require specific counseling about hoarseness risk, proper inhaler technique, and mouth rinsing after use 1, 3
• Any new medication from the above classes warrants heightened surveillance in patients with baseline vocal fold pathology 1
• Professional voice users require immediate evaluation if hoarseness develops after medication initiation 2, 3

Management Algorithm

• Perform laryngoscopy or refer for visualization rather than empirically discontinuing medications, as other serious pathology must be excluded 1, 2
• Document medication timing relative to hoarseness onset in the medical record 2
• Consider switching ACE inhibitors to angiotensin receptor blocker if chronic cough-induced hoarseness confirmed 1
• If vocal fold hematoma confirmed, manage anticoagulation carefully with hematology consultation 1

Common Pitfalls to Avoid

• Never attribute hoarseness to medications without laryngoscopic confirmation, especially in smokers or patients with risk factors for malignancy, as this delays cancer diagnosis 2, 4
• Do not empirically prescribe antibiotics, systemic corticosteroids, or anti-reflux medications for presumed medication-induced hoarseness before visualizing the larynx 1, 5, 4
• Do not overlook that hoarseness from sex hormones or antipsychotics may represent irreversible changes requiring immediate medication adjustment 1, 2
