Safely prescribing and administering Insulin


Welcome to eLearning module Safely prescribing and administering Insulin.

This module describes how to safely prescribe and administer insulin including:

  • dose calculation
  • use of the subcutaneous insulin prescribing chart
  • insulin titration
  • use of supplemental insulin.

A certificate is issued on completion.


On completion of the course you should be able to:

  • Calculate the dosage of basal and bolus insulin for a patient who is started on insulin in hospital.
  • Use the NSW Adult Subcutaneous Insulin Prescribing Chart (the chart) to prescribe or administer insulin for a patient who is in hospital.
  • Describe the steps to take when managing hyperglycaemia.
    • Review glucose levels over past few days.
    • Review current diabetes medications.
    • Review any contributing medications e.g. glucocorticoids.
    • Review how much supplemental (booster) insulin has been given.
    • Use the amount of supplemental (booster) insulin administered in the previous 24 hours to adjust regular insulin dose(s).
    • Assess preceding dose of insulin for any adjustment due to time of glucose excursion and adjust appropriate insulin dose.
  • Describe the safety aspects of using the chart.
    • Do not write ‘U’ as an abbreviation for units (it is pre-printed) as it may be misread as a zero resulting in a 10-fold dosing error.
    • Be careful of similar sounding insulin brands, noting the correct one (Common prefixes: Novo-, Hum-).
    • Be aware of different pre-mixed insulin formulations and charting the correct mix e.g. Humalog Mix25, Humalog Mix50.
  • Describe which type of insulin to adjust when:
    • fasting glucose is out of range
    • before evening meal glucose is out of range
    • bed time glucose is out of range.
