restless legs syndrome
"I had sudden permanent hearing loss in one ear while taking Neurontin/Gabapentin at 1:30 a.m., March 2, 2004. I was also taking the pain medication Hydrocodon/Lortab. I used both for 1 1/2 years for pain after back fusion. After a pharmacist told me it could cause hearing loss, I discontinued using it.

I have met others who also had this hearing loss while taking the medication. Others had less severe hearing loss.

At the time, side effects for this medication listed the chances for this happening as one out of 300, saying it was rare. Another listed it as one out of 1,000. This doesn't appear to be a rare incidence."
