Usual Adult Dose for Factor IX Deficiency

For intravenous use after reconstitution only.

AlphaNine SD(R): number of factor IX required in international units (IU) = body weight in kg x desired factor IX increase (%) x 1 IU/kg; adjust dose based on clinical response

Alprolix(R): number of factor IX required in IU = body weight in kg x desired factor IX increase (% or IU/dL) x reciprocal of observed recovery (IU/kg or IU/dL)
Minor to moderate bleeding: 30 to 60 IU/dL (or % of normal); repeat every 48 hours if further evidence of bleeding
Major bleeding: 80 to 100 IU/dL (or % of normal); repeat dose after 6 to 10 hours, then every 24 hours for the first 3 days.

  • Because of this products long half-life, dose may be reduced and dosing frequency extended after day 3 to every 48 hours or longer until bleeding is stopped and healing is achieved.
Perioperative management, minor surgery (including uncomplicated dental extraction): 50 to 80 IU/dL (or % of normal); a single dose may be sufficient; repeat as needed after 24 to 48 hours until bleeding stops and healing is achieved.
Perioperative management, major surgery: 60 to 100 IU/dL (or % of normal); consider repeat dosing after 6 to 10 hours, then every 24 hours for the first 3 days.
  • Due to this products long half-life, dose may be reduced and dosing frequency extended after day 3 to every 48 hours or longer until bleeding stops and healing is achieved.
Routine prophylaxis: 50 IU/kg once weekly or 100 IU/kg once every 10 days; adjust based on individual response.

BeneFIX(R), Rixubis(R):
Initial dose: number of factor IX required in IU = body weight in kg x desired factor IX increase (% or IU/dL) x reciprocal of observed recovery (IU/kg or IU/dL)
Average recovery: number of factor IX required in IU = body weight in kg x desired factor IX increase (% or IU/dL) x 1.4 (IU/kg or IU/dL)
  • On average, one IU/kg increased circulating activity of factor IX by 0.8 IU/dL (range 0.4 to 1.2 IU/dL)


Idelvion(R):
Initial dose: number of factor IX required in IU = body weight in kg x desired factor IX increase (% or IU/dL) x reciprocal of observed recovery (IU/kg or IU/dL)
Minor to moderate bleeding: 30 to 60 IU/dL (or % of normal); repeat every 48 to 72 hours until healing is achieved; a single dose is sufficient for most minor surgeries
Major bleeding: 60 to 100 IU/dL (or % of normal); repeat every 48 to 72 hours for the first week until bleeding stops or healing is achieved; maintenance dose is 1 to 2 times per week.
Perioperative management, minor surgery (uncomplicated hemarthrosis, muscle bleeding other than iliopsoas, oral bleeding): 30 to 60 IU/dL (or % of normal); a single dose is usually sufficient.
Perioperative management, major surgery (life or limb threatening hemorrhage, deep muscle bleeding including iliopsoas, intracranial, retropharyngeal): 60 to 100 IU/dL (or % of normal); repeat dose every 48 to 72 hours for 7 to 14 days until bleeding stops and healing is achieved; maintenance dose is 1 to 2 times weekly.
