Patient w/ neuromuscular disorders (e.g. myasthenia gravis), pre-existing vertigo, or hearing loss. Renal impairment. Elderly, childn. Pregnancy and lactation.
Adverse Reactions
Neurotoxic reactions (e.g. vestibular and cochlear function disturbance, optic nerve dysfunction, peripheral neuritis, arachnoiditis, encephalopathy); paraesthesia of face, rash, fever, angioneurotic oedema, eosinophilia; exfoliative dermatitis, azotemia, leucopenia, thrombocytopenia, pancytopenia, haemolytic anaemia, muscular weakness, amblyopia.

Drug Interactions
Additive neurotoxic and nephrotoxic effect w/ neomycin, kanamycin, gentamicin, cefaloridine, paronomycin, viomycin, polymyxin B, colistin, tobramycin, and ciclosporin. Enhanced ototoxic and nephrotoxic effect w/ ethacrynic acid, mannitol, furosemide and possibly other diuretics. May enhance the resp depressant effect of neuromuscular blockers.
