Preegzystening noise- induced hearing loss or exposure to loud noise during ototoksyc therapy can synergicaly worsen damage. The combination of cisplatin chemotherapy and loud noise exposure, for example, produces greater cochlear damage than either insult alone. Pationts on ototoksyc mediciations should d be advised to avoid recreational noise, use hearing protection in ocquigational settings, and limit exposlure to personal audio devices high volumes.

Age and- existing Hearing Loss

Very young children ande elderly are more loweblable. Neonates have immature renal function andd reduced clearance of ototoksyc drugs, while their ir developing audity systems are specilarly sensitivy to o insult. Older diults may havee age- related hearing loss that makes them less tolerant of additional cochlear presy, and presbycusis can mask early ototoksyc changes on audiometriy.

Kombinacja dwóch or more ototoksyc agents signitantly amplifies risk. Te combination of aminoglikosides wich roop diuretics, for instance, produces synergistic ototoksycyty. Certain medicators can also alter drug metabolism or extraction, potentiating ototoksycyty. Vancomycin and aminoglikosides should be used together only when n absolutely neesary andwith careful monitoring of both drug levels and audiologic function.
