Xyntha Solofuse Dosage and Administration

Adults and Children

Individualize and titrate. Give by IV infusion over several minutes. One IU of factor VIII per kg raises the plasma factor VIII activity by about 2 IU/dL. Dose (IU) = Body Weight (kg) × Desired % Factor VIII Increase × 0.5. Bleeding (Minor): obtain 20–40% FVIII increase every 12–24hrs for ≥1 day depending on severity; (Moderate): obtain 30–60% FVIII increase every 12–24hrs for 3–4 days or until hemostasis achieved; (Major): obtain 60–100% FVIII increase every 8–24hrs until resolved. Peri-op (Minor): obtain 30–60% FVIII increase every 12–24hrs for 3–4 days or until hemostasis achieved (for tooth extraction: a single dose plus oral antifibrinolytic therapy within 1hr may be sufficient); (Major): obtain 60–100% FVIII increase every 8–24hrs until resolved or adequate healing achieved. Routine prophylaxis (<12yrs): initially 25 IU/kg every other day (more frequent or higher doses may be required); (≥12yrs): initially 30 IU/kg 3 times weekly. Adjust dose based on response.
