“The best way to treat hemophilia is to replace the missing blood clotting factor so that the blood can clot properly. This is typically done by injecting treatment products, called clotting factor concentrates, into a person’s vein. Clinicians typically prescribe treatment products for episodic care or prophylactic care. Episodic care is used to stop a patient’s bleeding episodes; prophylactic care is used to prevent bleeding episodes from occurring. Today, it’s possible for people with hemophilia, and their families, to learn how to give their own clotting factor treatment products at home. Giving factor treatment products at home means that bleeds can be treated quicker, resulting in less serious bleeding and fewer side effects.”
