IVIG Dose & Infusion Rate Calculator

A calculation and administration guide for healthcare professionals

This calculator provides mathematical assistance using a clinician-prescribed IVIG dose and a selected infusion protocol. It does not prescribe treatment, assess suitability or replace the product monograph, hospital protocol, clinical monitoring or professional judgement.

1

Patient and product

IVIG product (locked)
GAMMAGARD LIQUID 10%
100 mg/mL (0.1 g/mL)
1 gram = 10 mL

Other products and concentrations are not selectable until their individual monograph and infusion protocol have been reviewed and added.

2

Prescribed dose

All subsequent calculations are for: Today's infusion

This tool never suggests what the prescribed dose should be. It only converts a dose that a doctor has already prescribed.

3

Infusion protocol

Rates may only be increased if the patient is tolerating the infusion.
Configured rate steps
0.5 mL/kg/hr1 mL/kg/hr2 mL/kg/hr4 mL/kg/hr6 mL/kg/hr8 mL/kg/hr

Each stage runs for the titration interval if tolerated. The final selected rate continues until the prescribed volume is completed. Protocol ceiling 8 mL/kg/hr.

Before the infusion

  • Confirm the doctor's prescription, indication and dose
  • Confirm the correct IVIG brand and concentration
  • Review previous IVIG exposure, product changes and prior reactions
  • Assess hydration and relevant renal, thrombotic, cardiac and hyperviscosity risks
  • Review hypersensitivity history and IgA-related concerns where relevant
  • Inspect the product for discolouration, cloudiness or particulate matter
  • Allow refrigerated product to reach room temperature according to product instructions
  • Do not shake the product
  • Record the product name, batch or lot number and expiry date
  • Establish baseline observations according to clinic protocol

During the infusion

  • Begin at the selected protocol's initial rate
  • Increase only if tolerated and clinically appropriate
  • Monitor the patient and vital signs according to the clinic protocol
  • Observe for headache, flushing, nausea, chills, changes in pulse or blood pressure, breathing difficulty, rash, pain or other adverse reactions
  • Slow or stop the infusion if an adverse reaction occurs
  • Escalate and manage the reaction according to the clinic's emergency and infusion-reaction protocol
  • Only resume at an appropriate lower rate if authorised by the treating clinician and clinically safe

After the infusion

  • Record the completed dose and volume
  • Record the maximum rate reached
  • Record start time, completion time and any interruptions
  • Document vital signs and any adverse events
  • Record the product and lot number
  • Provide patient-specific aftercare and escalation advice
  • Arrange appropriate monitoring or follow-up
