A likely diagnosis is:
a) Aminoglycoside toxicity
b) Multiple sclerosis
c) Presbycusis
d) Meniere's disease
e) Acoustic neuroma
ANSWER
The correct answer is A
Explanation
The aminoglycoside antibiotics are the most ototoxic of the commonly used drugs. The first sign of gentamicin ototoxicity is disequilibrium. Monitoring blood levels is the best way to avoid such problems, adjusting dose according to peak serum levels.
Other potentially ototoxic drugs include furosemide, ethacrynic acid, quinidine, and aspirin. Aspirin doses averaging 6 to 8 g/day predictably cause tinnitus and completely reversible hearing impairment.
