Monitor Blood Levels Peak =
time of maximum effect, commonly measured immediately after the drug has been infused
Monitor Blood Levels Trough =
level before the next dose (30 minutes before dose)
Monitor CBC =
especially WBC and differential to eval effectiveness (WBC will decrease to normal range)
