antihemophilic factor (recombinant)Skip to the navigationWhat is the most important information I should know about recombinant antihemophilic factor?You should not use this medicine if you have ever had a severe allergic reaction to antihemophilic factor in the past. Your body may develop antibodies to antihemophilic factor, making it less effective. Call your doctor if this medicine seems to be less effective in controlling your bleeding.

Each brand of recombinant antihemophilic factor may have specific instructions about keeping the medicine in a refrigerator or at room temperature, and for only a certain number of months. What is recombinant antihemophilic factor?Antihemophilic factor is a naturally occurring protein in the blood that helps blood to clot. A lack of antihemophilic factor VIII is the cause of hemophilia A. Recombinant antihemophilic factor works by temporarily raising levels of factor VIII in the blood to aid in clotting. Recombinant antihemophilic factor is used to treat or prevent bleeding episodes in adults and children with hemophilia A. It is also used to control bleeding related to surgery or dentistry in a person with hemophilia, and to prevent joint damage in people age 16 or older with severe hemophilia A and no prior joint damage. Recombinant antihemophilic factor is not for use in people with von Willebrand disease. Recombinant antihemophilic factor may also be used for purposes not listed in this medication guide. What should I discuss with my health care provider before using recombinant antihemophilic factor?You should not use this medicine if you have ever had a severe allergic reaction to antihemophilic factor, or if you are allergic to mouse, hamster, or beef proteins. Before using recombinant antihemophilic factor, your specific blood clotting disorder must be diagnosed as factor VIII deficiency.
