Immune Globulin Dosing: Actual Versus Ideal or Adjusted Body Weight Speci cally, the studies sought to answer whether dosing should be based on adjusted (AdjBW) or ideal body weight (IBW) versus actual body weight (ABW), especially in obese individuals IG therapy dosing is based on body weight in kilograms Since one kilogram is equivalent to 2 2 pounds, pounds are divided by 2 2 to convert them into kilograms
What is the evidence for using ideal body weight for IVIG dosing? Limited evidence suggests that dosing intravenous immunoglobulin (IVIG) based on ideal body weight (IBW) or adjusted body weight (adjBW) may be a preferable alternative to actual body weight (ABW) dosing Therefore, the use of IBW exclusively for IVIG dosing appears appropriate
IVIG Dose Calculator with BMI and Speciality Recommendations The dose calculator is a tool to be utilized when determining the adjusted body weight dose of IG (includes IVIG and SCIG) For further IG dosing and recommendation information refer to Ontario Immune Globulin Utilization Management (IGUM)
Title: Indications for and dosing of Intravenous Immune Guideline . . . All doses (except for pregnant patients) for IVIG will be calculated on the lesser of IBW or actual weight If the patient’s actual body weight is greater than 30% above IBW, the adjusted weight (adjBW) should be used Calculations for IBW AdjBW: IBW male: 50 kg + (2 3 x inches over 5 feet)
IVIG Dosing based on Adjusted Body Weight Calculation Dosing Weight is an adjusted body weight (of obese or overweight patients) and should only be used to calculate the dose of drugs for which there are recommendations specifying that the actual body weight should be adjusted for use in the dose calculations Dosing Weight = IBW + [0 4 x (Actual - IBW)]
UCxx Medical Center Updated April 2023 - ucop. edu The IVIG dose is generated based on ideal body weight (IBW) if the patient’s height is available or total body weight (TBW) if height is unavailable Actual body weight will be used if it is less than IBW IVIG dosing may be adjusted per pharmacy protocol to maximize efficacy and safety and promote appropriate use of a medication
