May increase risk of nephrotoxicity with other antibacterials (e.g. cephalosporins), ciclosporin, mannitol. Enhanced blockade of respiratory paralysis with skeletal muscle relaxants. May increase risk of nephrotoxicity and ototoxicity with platinum compounds, potent diuretics (e.g. ethacrynic acid, furosemide). Antagonistic effect with neostigmine and pyridostigmine.
