Medications and Adverse Voice Effects.

Objectives: To identify the medications used by patients with dysphonia, describe the voice symptoms reported on initial speech-language pathology (SLP) examination, evaluate the possible direct and indirect effects of medications on voice production, and determine the association between direct and indirect adverse voice effects and self-reported voice symptoms, hydration and smoking habits, comorbidities, vocal assessment, and type and degree of dysphonia.

Study Design: This is a retrospective cross-sectional study.

Methods: Fifty-five patients were evaluated and the vocal signs and symptoms indicated in the Dysphonia Risk Protocol were considered, as well as data on hydration, smoking and medication use.
