This patient presents with Streptococcus viridans endocarditis for which he is receiving antibiotic therapy with amikacin. Aminoglycoside antibiotics, such as amikacin, can be ototoxic and result in hearing loss. Ataxia is also a side effect associated with certain aminoglycoside antibiotics, but not amikacin. Stevens-Johnson syndrome is not associated with aminoglycoside antibiotics, but more so with anticonvulsant drugs. Rhabdomyolysis is seen with statin drugs, but is not usually with aminoglycosides.
