Ototoxicity refers to injury of the inner ear (cochlear and/or vestibular end organs) as the result of exposure to chemicals or medications. Although ototoxic injury is often unavoidable, certain measures may reduce the risk. The treating physician should consider choosing a therapeutically equivalent non-ototoxic drug whenever one is available, especially in patients with heightened risk (e.g. pre-existing cochlear hearing loss, renal insufficiency). During therapy with potentially ototoxic medications use the lowest dose compatible with therapeutic efficacy and, when indicated, periodically monitor serum peak and trough levels. Avoid simultaneous use of multiple ototoxic medications (e.g. aminoglycosides and loop diuretics) whenever clinical circumstances permit as this may increase the risk of permanent deficit. Should a patient develop auditory (hearing loss, tinnitus) or vestibular (vertigo or disequilibrium) symptoms during therapy with a potentially ototoxic medication, referral for audiometric testing is recommended and consideration should be given to obtaining the opinion of an otolaryngologist.
