You have to keep reading. Here is the rest of the quote:No, however I used it for well above the recommended 7 days. As noted by the lovely experts at Chicago Dizziness & Hearing, "With repeated dosing, progressive accumulation occurs in the inner ear. Release occurs slowly over several weeks after dosing has been stopped." I read somewhere else it takes months for levels accumulated in the inner ear to go down to zero.
"Hearing ototoxicity from oral absorption of Neomycin has been reported (Rappaport et al, 1986) and there may also be toxicity from ear drops in patients with perforated ear drums."
What you were quoting was not referring to your particular scenario (i.e. drops with no perforation). Ototoxicity from Neomycin via systemic absorption is scientifically established (although you'd have to have repeated dosage, as you mention in your quote).
Per research, it seems extremely unlikely that the drops you took, while your ear drums were intact, were ototoxic to you.
Why were you prescribed those drops? This could simply be a case of correlation vs causation.
