Anti-Inhibitor Coagulant Complex Dosage

Medically reviewed by Drugs.com. Last updated on Mar 5, 2025.

Usual Adult Dose for Bleeding

General Dosage Guidelines:
50 to 100 units/kg IV

Comments:

• Patients with a factor VIII inhibitor titer less than 5 Bethesda units (BU) may be successfully treated with antihemophilic factor. Patients with a titer between 5 and 10 BU may be treated with antihemophilic factor or this drug. Patients with a titer greater than 10 BU have generally been refractory to treatment with antihemophilic factor.
• Patients receiving more than 100 units/kg must be monitored for the development of disseminated intravascular coagulation (DIC) and/or symptoms of acute coronary ischemia. High doses should only be given if necessary to stop bleeding.

Use: Control of spontaneous bleeding episodes or to cover surgical interventions in hemophilia A and hemophilia B patients with inhibitors.

Joint Hemorrhage:
50 units/kg IV every 12 hours until clear signs of clinical improvement appear (e.g., relief of pain, reduction of swelling, or mobilization of the joint). Dose may be increased to 100 units/kg if hemorrhage does not stop.

Maximum dose: Two administrations of 100 units/kg a day or a total daily dose of 200 units/kg should not normally be exceeded.

Mucous Membrane Bleeding:
50 units/kg IV every 6 hours. Dose may be increased to 100 units/kg if hemorrhage does not stop.

Maximum dose: Two administrations of 100 units/kg a day or a daily total dose of 200 units/kg should not be exceeded.

Comments: Monitor the patient carefully (i.e., examine for cessation of visible bleeding) and perform repeated measurements of hemoglobin/hematocrit.

Soft Tissue Hemorrhage:
100 units/kg IV every 12 hours

Maximum dose: Total daily dose of 200 units/kg should not be exceeded.

Other Severe Hemorrhage:
100 units/kg IV every 6 to 12 hours

Maximum dose: Single doses of 100 units/kg and a daily dose of 200 units/kg should not be exceeded unless the severity of bleeding warrants and justifies the use of higher doses.

Comments: May be indicated at 6-hour intervals until clear clinical improvement is achieved.
