Treatment Options for Bleeding Disorders

There are many different types of therapies for bleeding disorders, and new ones are in development. Each person may respond to a treatment in their own way, so it is important to work closely with your hematologist to find a treatment that works for you.

Factor Replacement Therapies

Often referred to as “factor,” these products use a molecule that is either similar to natural factor found in humans (recombinant) or use an actual human molecule (plasma derived.) These treatments increase the amount of factor in the body to levels that lead to better clotting, and therefore less bleeding. The therapy is taken intravenously via an injection into a vein. This process is also called "infusion." There are two types of factor replacement therapies: standard half-life and extended half-life (EHL)

Standard half-life therapies: Standard half-life therapies are used to treat hemophilia A and B, some types of von Willebrand disease, and some rare factor disorders. Dosing can be anywhere from three times a week to every day, depending on the person.

Extended half-life (EHL) therapies: EHL contains a molecule that has been modified in some way to delay the breaking down of factor in the body. This results in higher levels of factor in the body lasting for longer, resulting in less frequent infusions. How long the factor is effective in the body depends on the person. Extended half-life therapies are mostly used to treat hemophilia A and B.

Non-factor Replacement Therapies

These products help prevent bleeding or assist in better clotting using other methods in the body besides replacing low factor levels. Non-factor replacement therapies include:
 
DDAVP (desmopressin acetate) is the synthetic version of vasopressin, a natural antidiuretic hormone that helps stop bleeding. In patients with mild hemophilia, it can be used for joint and muscle bleeds, for nose and mouth bleeds, and before and after surgery. It comes in an injectable form and a nasal spray. The manufacturer of DDAVP nasal spray issued a recall of all US products and does not expect to begin resupplying until 2022. DDAVP is used to treat von Willebrand disease and mild hemophilia A.

Aminocaproic acid prevents the breakdown of blood clots. It is often recommended before dental procedures, and to treat nose and mouth bleeds. It is taken orally, as a tablet or liquid. MASAC recommends that a dose of clotting factor be taken first to form a clot, then aminocaproic acid, to preserve the clot and keep it from being broken down prematurely. This can be used to manage bleeding in people with hemophilia A, B and VWD.


Emicizimab (Hemlibra) is a laboratory-engineered protein that works by performing a key function in the clotting cascade that is normally carried out by the FVIII protein. It can be prescribed for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children of all ages, newborn and older, with hemophilia A with and without factor VIII inhibitors. Emicizumab is not infused, but injected under the skin (subcutaneously.)

Bypassing agents are used to treat bleeds in people with hemophilia with inhibitors. These treatments contain other factors that can stimulate the formation of a clot and stop bleeding.
