Choosing an indication applies its total course dose in g/kg. Set the days field to spread that total (for example Guillain-Barre: 2.0 g/kg over 5 days = 0.4 g/kg per day). Choose "Enter dose manually" to type your own g/kg.
Total dose is split equally across each day. E.g. 2 g/kg over 5 days = 0.4 g/kg per day.

Check the product vial label. Most modern IVIG products are 10%.
Standard protocol is recommended for new or high-risk patients. Rapid may be used for patients who have tolerated IVIG well previously.

Total IVIG dose: 148.6 g over 1 day

  • BMI is 26.1 kg/m². Adjusted body weight of 74.3 kg is used (IBW 70.5 kg + 40% of the 9.5 kg above IBW).
  • Single-day infusion: 148.6 g in 1486 mL of 10% solution, estimated infusion time 7.2 hours.
  • These figures are a calculation aid only. The prescriber must confirm the dose, monitor for infusion reactions, and adjust the rate or stop infusion if adverse effects occur.

Next stepCross-check the calculated dose with the product monograph maximum rate. Pre-medicate per local protocol if the patient has a history of infusion reactions.
