Amikacin injection (IV/IM) dosing must be individualized by age, actual/adjusted body weight, infection, renal function, dialysis status, and drug-level monitoring.
Common conventional dosing for adults and children with normal renal function:
- 15 mg/kg/day, divided as:
- 7.5 mg/kg every 12 hours, or
- 5 mg/kg every 8 hours
- Usual maximum: 1.5 g/day. DailyMed prescribing information
Uncomplicated UTI: 250 mg every 12 hours may be used in selected patients.
Newborns: label dosing is 10 mg/kg loading, then 7.5 mg/kg every 12 hours, but neonatal schedules vary substantially by gestational age and postnatal age.
Renal impairment: do not use the normal schedule unchanged. The dose and/or interval must be adjusted using creatinine clearance and amikacin serum concentrations. Amikacin can cause serious kidney injury and irreversible hearing/vestibular toxicity, especially with high levels or prolonged treatment.
Please provide:
- Age and weight
- Indication/culture
- Serum creatinine or creatinine clearance/eGFR
- IV or IM, and whether on dialysis
Then I can help check an appropriate regimen, but a prescriber or clinical pharmacist should authorize the final dose.
