​​​​​​ReFacto AF® (moroctocog alfa) is indicated for the treatment and prophylaxis of bleeding in patients with haemophilia A (congenital factor VIII deficiency). ReFacto AF® is appropriate for use in adults and children of all ages, including newborns. ReFacto AF® does not contain von Willebrand factor, and hence is not indicated in von Willebrand's disease.1

Flexible dosing

No two days are the same. No two patients are the same. ReFacto AF® offers frequent, flexible dosing so your patients are covered for everyday life.1-3

ReFacto AF® can be administered as on-demand or prophylactic treatment.1


For long-term prophylaxis against bleeding in patients with severe haemophilia A, the usual doses are 20–40 IU of factor VIII per kg body weight at intervals of 2–3 days.1

In some cases, especially in younger patients, shorter dose intervals or higher doses may be necessary.1

​​​​​​​In the case of the following haemorrhagic events, the factor VIII activity should not fall below the given plasma levels (in percentage of normal or in IU/dL) in the corresponding period.1

The following table can be used to guide dosing in bleeding episodes and surgery:  

Degree of haemorrhage/Type of surgical procedure

Factor VIII level required (%) or (IU/dL)

Frequency of doses (hours) / Duration of therapy (days)




​​​​​​​Early haemarthrosis, muscle bleeding or oral bleeding


Repeat every 12–24 hours. At least 1 day, until the bleeding episode as indicated by pain is resolved or healing is achieved.

More extensive haemarthrosis, muscle bleeding or haematoma 


Repeat infusion every 12-24 hours for 3–4 days or more until pain and acute disability are resolved.

Life-threatening haemorrhage


Repeat infusion every 8–24 hours until threat is resolved.




Minor surgery including tooth extraction


Every 24 hours, at least 1 day, until healing is achieved.

Major surgery

80–100 (pre- and post- operative)

Repeat infusion every 8-24 hours until adequate wound healing, then therapy for at least another 7 days to maintain a factor VIII activity of 30% to 60% (IU/dL).
