High-dose extended interval ("once-daily")

Single level: Check random drug level 6-14 hours after the start of infusion.  Compare to nomogram (below)

Paired levels: Check peak drug level 2 hours after and random level 6-14 hours after infusion.  Consult ID pharmacy for assistance.

Traditional dosing Paired levels: Check peak drug level 30 minutes after end of infusion (goal 20-30 mg/L) and trough level immediately before next dose (goal <4 mg/L).









**If amikacin 20 mg/kg is used. Adjust the measured level with the following equation before plotting the level onto the Amikacin 15mg/kg Extended Interval Nomogram Level for the plot = Measured level x 0.75

All use of intravenous amikacin requires authorization from the Antimicrobial Stewardship Program or consulting ID fellow
