Wished I could help you here, Mike, but all I know about this drug is that it is a sulfa drug (sulfonylurea).
For what it's worth, this drug is listed as a class 2 drug (class 1 being the least ototoxic, and class 5 the most) in my ototoxic drug book. Ototoxic side effects are tinnitus and dizziness.
With that said, I guess it is crap shoot to see if it bothers you or not.
JM - can you let us know whereyou managed to get hold of a book on ototoxic drugs please?
In the UK they start at around £175!
Thanks
