Optimize hemophilia A treatment with our Hemlibra dosing calculator. This specialized tool helps patients and clinicians calculate emicizumab-kxwh maintenance doses, loading schedules, and prophylaxis regimens for 2025, with adjustments for weight and inhibitor status.
Important Safety Notice: Hemlibra may increase the risk of thrombotic microangiopathy and thromboembolism when used with activated prothrombin complex concentrate (aPCC). Always consult with a hematologist before initiating or changing dosing regimens.
How Our Hemlibra Dosing Calculator Works
This Hemlibra calculator uses the latest 2025 prescribing guidelines to determine appropriate emicizumab-kxwh regimens:
Calculates loading doses for the initial 4-week period
Determines maintenance doses based on weight and frequency
Adjusts for inhibitor status (with/without Factor VIII inhibitors)
Considers bleeding history for higher-risk patients
Projects treatment costs based on current pricing
2025 Dosing Formula:
Loading Dose = 3 mg/kg weekly × 4 weeks
Maintenance Dose = 1.5 mg/kg weekly, 3 mg/kg every 2 weeks, or 6 mg/kg every 4 weeks
Pediatric Adjustment = +10% dose for patients under 12 years
Cost Estimate = (Dose × Frequency × 52) × $4.50 per mg
