  • If the dose is weight-based and weight is provided, the mass and volume of drug will also be calculated
    • Doses are calculated using total body weight unless otherwise specified
    • For volume, verify the correct preparation of the drug is selected
  • If the drug has different dosing based upon age (e.g. pediatric, elderly) and age is provided, an adjusted dose will be provided if the data is available
  • Some doses may have important additional information which will be shown as a link below the dose
