Treating bleeding in haemophilia A
Preventing bleeding in haemophilia A
Supporting haemostasis around surgery or dental procedures as directed by a specialist
It is not indicated for von Willebrand disease because it does not contain von Willebrand factor
How does moroctocog alfa work?
Factor VIII helps activated factor IX activate factor X, leading to thrombin and fibrin formation—the steps that produce a stable blood clot. Moroctocog alfa temporarily restores factor VIII activity, helping correct the bleeding tendency in haemophilia A.

Route: Parenteral
Strengths: 250 units, 500 units, 1000 units, 2000 units, 3000 units
How to take moroctocog alfa
Use only as taught by the haemophilia team. Mix the powder with the solvent in the dual-chamber pre-filled syringe by gently rotating it, then inspect the solution: it should be clear or slightly opalescent and colourless. Do not use it if particles or discolouration are visible. Administer into a vein using the supplied infusion equipment, record the product name and batch number, and dispose of used equipment safely. Food does not affect an intravenous infusion.
Treatment should begin under a clinician experienced in haemophilia A.
Patients and carers should receive appropriate preparation and infusion training.
Do not mix it with other medicines or infusion solutions.
Keep adequate supplies and consult the haemophilia team before travel.

moroctocog alfa in pregnancy
Experience with factor VIII during pregnancy is limited because haemophilia A rarely occurs in women. Moroctocog alfa should be used during pregnancy only when clearly indicated, with advice from the haemophilia and maternity teams.
moroctocog alfa while breastfeeding
Evidence during breastfeeding is limited. Use should be considered only when clearly indicated after discussion with the prescribing specialist.
moroctocog alfa interactions
No direct interactions between recombinant factor VIII products and other medicines have been reported. However, medicines that increase bleeding risk still require review because of the underlying bleeding disorder.
Aspirin and non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen
These may increase bleeding or bruising and should not be started without agreement from the haemophilia team.
Anticoagulants, such as warfarin, heparin, apixaban or rivaroxaban
These can increase bleeding risk and require specialist assessment if clinically necessary.
