What is Feiba VH Immuno?

Feiba VH Immuno is used in people who have hemophilia and have developed antibodies to clotting factor medications.

Hemophilia, an inherited blood-clotting disorder, is often treated with medicines containing clotting factors that help control bleeding. When the body develops antibodies or "inhibitors" to the clotting factor, this treatment becomes less effective in preventing bleeding episodes. Feiba VH Immuno works by bypassing the effects of these inhibitors to improve blood clotting and decrease the risk of bleeding.

Feiba VH Immuno is used to treat or prevent bleeding episodes in people with hemophilia A or B who have developed inhibitors. Feiba VH Immuno is also used to control bleeding related to surgery in people with hemophilia and inhibitors. This medicine is not for treating bleeding episodes in people who do not have inhibitors.

Feiba VH Immuno may also be used for purposes not listed in this medication guide.
