Adults with
hemophilia and parents of children with hemophilia can
learn to inject (infuse) replacement
clotting factors. Children may also be taught to
infuse themselves with clotting factors by age 10. Younger children and those
who have developed antibodies (inhibitors) may not be able to infuse
themselves.
Being able to infuse at home will speed treatment and prevent much of
the damage bleeding can cause to muscles and joints. Clotting factor comes from
donated blood or is produced in a lab (using recombinant
DNA technology).
People with moderate or mild hemophilia may only need to infuse
clotting factors on demand after an injury or before participating in an
activity that may cause an injury. People with severe hemophilia may choose a
regular schedule for clotting replacement therapy in order to help prevent
bleeding episodes.
