A friend of mine went deaf due to an allergic reaction to a widely used antibiotic (that is no longer produced). Other than that, I can't think of anything that I have come across personally. That was in the sixties.
Had a friend who went 80/60% deaf from a reaction to an antibiotic as an infant in the 80s but crucially this was in a developing country.
