Clinical monograph

How it works

It replaces deficient factor VIII, which acts as a cofactor in the intrinsic coagulation pathway to support activation of factor X and normal clot formation.

Prescribing in practice

  • Development of inhibitory antibodies to factor VIII is an important complication that reduces efficacy, so patients should be monitored for inhibitors, especially with intensive or early treatment.
  • Hypersensitivity reactions can occur, and the brand and batch number should be recorded at each administration for traceability.
  • Dosing and the choice of product are individualised and managed through a specialist haemophilia centre.

Monitoring

Monitor factor VIII activity and clinical response, and test for inhibitor development if response is suboptimal.

Counselling the patient

  • Report any rash, wheeze or swelling during or after an infusion.
  • Record the product name and batch number used for each treatment.

Evidence & guidelines

Factor VIII replacement is the standard of care for haemophilia A and is delivered through specialist haemophilia services.
