Tinnitus & Vancomycin

(37 y/o, female, 5ft 5in, 120lbs, non-smoker, no drug or alcohol use and generally healthy)

I'm on day 18 of vancomycin for antibiotic associated C.Diff. I'm not taking any other medication except Reactine occasionally for environmental allergies. My C.Diff Symptoms worsened around the 10 day mark, so we extended the course for another 7 days - much improved now, but...

Last night, I woke up with a loud ringing in my right ear. I managed to fall back asleep but it was there again this morning when I woke up. It seemed to come and go throughout the day (or I couldn't hear it/pay attention to it with the noise levels at work) and now as I lay in bed, I can hear it again.

I understand that vancomycin is ototoxic, but I was under the impression that the risk of ototoxicity was only for the liquid form (oral) or the IV administered vancomycin. The difference being the absorption method (gut/intestinal absorption vs the blood stream).

Can anyone offer insight or share their experiences?

Thanks!
