I am on Lasix 120mg + per day for fluid retention secondary to heart failure created during valve surgery. I am concerned re Lasix's role in deafness.Literature on Lasix's role in deafness is equivocal (I have only one hearing ear; the acoustic nerve in the other ear was destroyed during brain surgery) and am concerned about preserving hearing in the remaining ear. Am considering switching to Bumex and would like to hear from others c similar issues.
