Description
Alhemo, or concizumab, is a biological agent indicated to treat the hematologic disorder hemophilia B. Hemophilia B is a condition where the blood does not clot normally, and the person is more likely to have excessive bleeding. Symptoms include unexplained bleeding, blood in the urine or stool, large or deep bruises, or signs and symptoms of serious bleeds.
Alhemo works by binding to the protein TFPI. Normally, TFPI prevents the excessive formation of blood clots. By binding to this protein, Alhemo prevents TFPI from working, increases blood clotting, and reduces excessive bleeding.

Alhemo is administered on a set schedule based on directions from your doctor. After four weeks of treatment, your doctor will measure the level of Alhemo in the blood and adjust the dose accordingly.
