For adult usage: Factor IX complex, Profilnine should be administered intravenously, promptly following reconstitution with the supplied diluent. Although Profilnine is stable for at least three (3) hours at room temperature after reconstitution, prompt administration is recommended to avoid the ill effect of any inadvertent bacterial contamination occurring during reconstitution. Administer at room temperature, do not refrigerate after reconstitution and discard any unused contents.
A 1.0% increase in factor IX (0.01 IU)/IU administered/kg can be expected.1, 5 The amount of Profilnine required to establish hemostasis will vary with each patient and depends on the circumstances. The following formula may be used as a guide in determining the number of units to be administered: (See equation.)

In normal clinical practice there is variability among patients and their clinical condition. Therefore, the factor IX level of each patient should be monitored frequently during replacement therapy.
Mild to moderate hemorrhages may usually be treated with a single administration sufficient to raise the plasma factor IX level to 20 to 30 percent. In the event of more serious hemorrhage, the patient's plasma factor IX level should be raised to 30 to 50 percent. Infusions are generally required daily.
Surgery in patients with factor IX deficiency requires that the factor IX level should be raised to 30 to 50 percent for at least one week following operation. For dental extractions, the factor IX level should be raised to 50 percent immediately prior to the procedure; additional factor IX complex may be given if bleeding recurs.
