[1]  NSPBCP gratefully acknowledges the Pharmacy Department of Sunnybrook Health Sciences Centre for the use of their template for the Adjusted Body Weight Calculator. The NSPBCP made the following modifications:

  • There is no upper limit of actual weight for the dose calculations
  • Dosage increments of 0.1, 0.2 and 0.3gm/kg in addition to 0.4 and 1gm/kg
[2] Ideal Body Weight (IBW), Devine Formula is:
         Ideal Body Weight (male) = 50.0 kg + 2.3 kg (each inch > 5 feet)
       Ideal Body Weight (female) = 45.5 kg + 2.3 kg (each inch > 5 feet)

[3] 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)]
  • exception:  if Actual < IBW,  then Dosing Weight = Actual
  • (Actual = actual body weight)
