Novoeight^® dosing guidelines.¹

The required dosage can be determined using the following formula:

Formula for determing Novoeight® dosing. Body weight (kg) X Desirded Factor VIII Increase (IU/dl or % normal) X 0.5 = Dosage (IU). Example: 50 Kg x 30 (% normal) x 0.5 = 750 IU

Refer to dosing tables below for additional guidance.

For complete dosing information please see the Prescribing Information.

Dosage and duration of treatment depend on the severity of the factor VIII deficiency on the location and extent of bleeding, and the patient’s clinical condition. Careful monitoring of replacement therapy is necessary in cases of major surgery or life-threatening bleeding episodes.

Each vial of Novoeight^® contains the labeled amount of recombinant factor VIII in international units (IU). One IU of factor VIII activity corresponds to the quantity of factor VIII in one milliliter of normal human plasma. The calculation of the required dosage of factor VIII is based on the empirical nding that one IU of factor VIII per kg body weight raises the plasma factor VIII activity by two IU/dL. This relationship causes a factor of 0.5 to be present in the dose calculation formula shown above.

Base the dose and frequency of Novoeight^® on the individual clinical response. Patients may vary in their pharmacokinetic and clinical responses.
