Ototoxicity, nephrotoxicity, neurotoxicity

Adults: 15-20 mg/kg/day IM or IV, in divided doses Q8H or Q12H, maximum dose 1.5 g/day

Infants and Children: 5-7.5 mg/kg/dose every 8 hours

Dosage adjustment: Loading dose 7.5 mg/kg, then according to ClCr (ml/min) to calculate maintenance dosage:
1. ClCr ≧60 mL/min: Administer Q8H
2. ClCr 40-60 mL/min: Administer Q12H
3. ClCr 20-40 mL/min: Administer Q24H
4. ClCr <20 mL/min: Loading dose, then monitor levels
5. Intermittent hemodialysis (administer after hemodialysis): 5-7.5 mg/kg Q48-72H
6. CVVH/CVVHD/CVVHDF: Loading dose of 10 mg/kg followed by maintenance dose of 7.5 mg/kg Q24-48H.
