Long-term continued use of prescription opiates, such as Vicodin, et al, will have that effect........also some anti-depressant drugs (MAOI Inhibitors)will have that side effect, particularly if combined with anti-psychotic meds, however, with the psychoactive meds, the effect is usually transient, and passes with continued use.

Lord, I hope not! I've been on 7.5/325 Vicodin every 4 hrs for 12 years given the 6 screws in my back. It's the only way I can get out of bed in the morning and get any work done at all!
Can't say that it has effected my hearing any, except when "Toots" gets on a roll, and that's pretty much selective. heh!
