Attachment: Intravenous Immunoglobulin Dosing Education

Hello Huntsville Hospital Main Pharmacists,

The P&T Committee has approved a dosing change for IVIG to be used on ADULT INPATIENT orders.

IVIG will now be dosed based on ideal body weight (IBW) or adjusted body weight (AdjBW) in obese patients. 

All IVIG doses will be calculated by pharmacy.

This change will be implemented starting April 2^nd.

Dosing Information:

• Use ideal body weight (IBW) on all adult inpatient orders

• Exceptions:
  
  o   Obese patients (total body weight ≥ 130% of IBW) à use AdjBW
  
  o   If patients total body weight < IBW à use  total body weight

• Adjusted Body Weight (AdjBW) Equation:

  o   AdjBW   =    IBW + 0.5 ( Total body weight – IBW) = kg

  o   Or you can utilize the online calculator. ***( IVIG DOSE CALCULATOR) ***

• Doses will continue to be rounded to the nearest 5 grams

• Pediatric patients and outpatient IVIG orders are excluded

Further education will be provided in this month’s staff meeting.  Please see the attachment for more information.

Thank you for your time and please feel free to contact me if you have any questions
