Interactions
Synergistic with ampicillin, benzylpenicillin and other beta-lactam antibiotics. Increased risk of severe respiratory depression when used concurrently with anaesthetics or opioids. May reduce renal clearance of zalcitabine and induce hypocalcaemia when used with biphosphonates. Not to be used with agalsidase alfa or beta as it may inhibit alpha-galactosidase activity.
Potentially Fatal: Increased incidence of ototoxicity when combined with ethacrynic acid and furosemide. Cephalosporins, ciclosporin, cisplatin, vancomycin, hydrocortisone and indometacin potentiate nephrotoxicity. Potentiates neuromuscular blocking agents.

<1%
Drowsiness, Headache, Pseudomotor cerebri, Photosensitivity, Allergic reaction, Erythema, Anorexia, Nausea/vomiting, Weight loss, Increased salivation, Enterocolitis, Granulocytopenia, Agranulocytosis, Thrombocytopenia, Elevated LFT
Burning, Stinging, Tremors, Muscle cramps, Weakness, Dyspnea
Potentially Fatal: Nephrotoxicity, ototoxicity and neuromuscular blockade (may unmask or aggravate myasthaenia gravis).
Mode of Action
Gentamicin is an aminoglycoside that binds to 30s and 50s ribosomal subunits of susceptible bacteria disrupting protein synthesis, thus rendering the bacterial cell membrane defective.
