Ototoxicity: When Drugs Affect Your Hearing

A few weeks ago, the topic of ototoxicity popped up on in an email list about musician health.  I had never heard of it before, and thought I should do some research.  First off though, what is otoxicity?  The prefix OTO refers to structures of the ear, and toxicity meaning poison, so total meaning poisonous to the ear and its structures.  Many different pharmaceuticals can cause ototoxicity, which can be anything from temporary hearing loss to permanent damage to the vestibular system.  Here are the categories of damage:

1. Cochlear system: short or long term hearing loss, tinnitus, hearing distortion, hyperacusis, and more

2. Vestibular system: Vertigo, equilibrium disorders, dizziness, and more

3. Nervous system: with damage to the ears, damage to the nervous system and message processing can follow

4.  Ear structure damage: middle or outer ear damage, infections, etc.

What drugs are ototoxic?  Depending on the article, I've seen estimates from 200-800 different drugs as being ototoxic.  Some of the more common ones are chemotherapy drugs (cisplatin), certain beta-blockers, antibiotics, antidepressants, aspirin, and diuretics.  Not all drugs within these classes are ototoxic, but some are.  If you're on any kind of prescription medicine, check with your physician about ototoxic side effects and whether there are other alternatives with non hearing related consequences.  In addition, one's absorption of the drug impacts the side affects, as well as any genetic propensity for hearing loss, kidney damage, or exposure to loud sounds.  Frequency and dose are also factors.  As always, talk with a physician if you believe your medication to be impacting the structures of your ear negatively.
