YOU WROTE:

"Current medical status: I am currently experiencing some relatively low volume ringing and slight whistling in both of my ears. I believe it could be Tinnitus. I had experienced the noise primarily in my left ear until a few weeks ago when I felt that I noticed the noise worsening in my right ear. It's making it a bit difficult to sleep at night.
Current medical treatment: I've been to one doctor (not an ENT or specialist) and had him look at whether it could be a result of ear wax buildup. I thought this might have been the case because about 16 months ago I had a physical and was told that I had quite a bit of ear wax buildup. This doctor, however, said there was no buildup to speak of."




Tinnitus is definitely one of the side effects of Vicodin. However, tinnitus is a rather rare side effect and usually occurs accompanied with a hearing impairment due to prolonged overdose use. No data can be found about whether Vicodin induced Tinnitus can be reversed when the medication is no longer used. Because there are many other reasons for tinnitus, you might want to consult ear, nose, throat specialist to identify the exact reason and start to plan treatment for managing or eliminating tinnitus.

500mg is only the ammount of acetaminophen or APAP in the drug, you either take half or a whole of 5mg , 7.5mg , or a 10mg vicodin. I doubt it would give you hearing loss if your only taking an ammount like 2.5mg...everyone in pain management would be deaf otherwise
