There are studies though, and my conclusion is that it's still mostly inconclusive. Still, if my tinnitus suddenly worsened id be down at the doctor's begging for the steroids.
After a week my hearing was back to normal, so at least in my case it worked (although I guess there's a question of whether it would have recovered anyway)
I might have seen Ibuprofen mentioned explicitly in relation with hearing loss.
Can anyone confirm or deny if taking Ibuprofen could help if one is stuck without a doctor?
Most over-the-counter painkillers (other than acetaminophen/paracetamol) are non-steroidal anti-inflammatory drugs. OTOH, if the reason steroids work against hearing injuries is anti-inflammatory properties, NSAIDs might also work.
(OTOH, regular use of NSAIDs and acetaminophen is known to sometimes cause tinnitus and hearing loss, so, there’s that...)
