what it is used for

ALTUVOCT contains the active substa

nce efanesoctocog alfa, a replacement

factor VIII protein.

ALTUVOCT is used to treat and preven

t bleeding in patients 2 years and above

with severe or moderate haemophilia

A (the factor VIII blood level is 5% or

less).

Factor VIII is a protein naturally found i

n the body and is necessary for the blood

to form clots and stop bleeding. In pat

ients with haemophilia A, factor VIII is

missing or not working properly.

ALTUVOCT replaces the deficient or m

issing factor VIII. ALTUVOCT increases

factor VIII levels in the blood, helping

blood to form clots at the site of

bleeding which temporarily corrects t

he bleeding tendency.
