Additional Information
Collection Guideline:
Obtain a baseline creatinine and repeat at 1-3 day intervals.
Begin monitoring after steady state is achieved (usually 3-4 doses).
Monitor at least one peak (60-90 min after IM or 30-60 min IV) and one trough (within 30 min of next dose).
Repeat trough measurements at 3-4 day intervals or sooner if warranted by clinical status
Base frequency of monitoring on changes in dose and patient symptoms
Perform urinalysis by day 3 and repeat as necessary to assess early proximal tubular dysfunction
