Usual Adult Dose for Factor IX Deficiency

The amount of this drug required to establish hemostasis will vary with each patient and circumstance.

Bebulin(R): 1 international unit (IU) factor IX/kg will increase the plasma level of factor IX by 0.8%.
Profilnine(R): 1 IU factor IX/kg will increase the plasma level of factor IX by 1%.

Minor hemorrhage (e.g., early hemarthrosis, minor epistaxis, gingival bleeding, mild hematuria):
Bebulin(R):

Initial dose (desired factor IX level: 20% of normal): 25 to 35 IU/kg IV once; a single dose is usually sufficient; otherwise, a second dose may be given after 24 hours.

Profilnine(R):

Initial dose (desired factor IX level: 20% to 30% of normal): 20 to 30 IU/kg IV every 16 to 24 hours for 1 to 2 days until hemorrhage stops and healing has been achieved.

Moderate hemorrhage (e.g., severe joint bleeding, early hematoma, major open bleeding, minor trauma, minor hemoptysis, hematemesis, melena, major hematuria):
Bebulin(R):

Initial dose (desired factor IX level: 40% of normal): 50 to 65 IU/kg IV; average duration of treatment is 2 days or until adequate wound healing occurs; more severe hemorrhage will require several doses at approximately 24-hour intervals; for maintenance therapy, two-thirds of the initial dose is usually required.

Profilnine(R):

Initial dose (desired factor IX level: 20% to 30% of normal): 20 to 30 IU/kg IV every 16 to 24 hours for 2 to 7 days until hemorrhage stops and healing has been achieved.

Major hemorrhage (e.g., severe hematoma, major trauma, severe hemoptysis, hematemesis, melena):
Bebulin(R):

Initial dose (desired factor IX level: 60% of normal or greater): 75 to 90 IU/kg IV; average duration of treatment is 2 to 3 days or until adequate wound healing occurs; more severe hemorrhage will require several doses at approximately 24-hour intervals; for maintenance therapy, two-thirds of the initial dose is usually required.

Profilnine(R):

Initial dose (desired factor IX level: 30% to 50% of normal): 30 to 50 IU/kg IV every 16 to 24 hours.
Maintenance dose (desired factor IX level: 20% of normal): 20 IU/kg IV for 3 to 10 days or until healing has been achieved.

Dental surgery:
Bebulin(R):

Initial dose (day of operation; desired factor IX level: 40% to 60% of normal): 50 to 75 IU/kg IV 1 hour prior to surgery; one infusion should be sufficient; in case of extraction of several teeth, replacement therapy for up to 1 week may be necessary using the same dose.

Profilnine(R):

Initial dose (desired factor IX level: 50% of normal immediately before procedure): 50 IU/kg IV prior to surgery.
Maintenance dose (desired factor IX level: 30% to 50% of normal): 30 to 50 IU/kg IV every 16 to 24 hours for 7 to 10 days following surgery or until healing has been achieved.

Bebulin(R):

Initial dose (day of operation; desired factor IX level: 40% to 60% of normal): 50 to 75 IU/kg IV 1 hour prior to surgery.
Initial postoperative dose (week 1 to 2 or until adequate wound healing; desired factor IX level: 20% to 40% of normal): 25 to 65 IU/kg IV; average treatment interval will be 12 hours initially, then every 24 hours later in the postoperative period.

Profilnine(R):

Initial dose (desired factor IX level: 30% to 50% of normal): 30 to 50 IU/kg IV prior to surgery.
Maintenance dose (desired factor IX level: 30% to 50% of normal): 30 to 50 IU/kg IV every 16 to 24 hours for 7 to 10 days following surgery or until healing has been achieved.

Initial postoperative dose (week 1 to 2; desired factor IX level: 20% to 60% of normal): 25 to 75 IU/kg IV; average treatment interval will be 12 hours initially, then every 24 hours later in the postoperative period.
Late postoperative dose (week 3 or until adequate wound healing; desired factor IX level: 20% of normal): 25 to 35 IU/kg IV; average treatment interval will be 12 hours initially, then every 24 hours later in the postoperative period.

Profilnine(R):

Initial dose (desired factor IX level: 30% to 50% of normal): 30 to 50 IU/kg IV prior to surgery.
Maintenance dose (desired factor IX level: 30% to 50% of normal): 30 to 50 IU/kg IV every 16 to 24 hours for 7 to 10 days following surgery or until healing has been achieved.
