Quizplus · Accepted Answer

Prolonged use of carbamide peroxide can cause irritation and damage to the tympanic membrane, leading to hearing loss. The outer ear canal is less likely to be affected, and damage to the auditory nerve is not a common side effect of this medication. The concentration of carbamide peroxide in otic preparations is typically 6.5%, and 8.5% solutions are not commonly used.
