Alhemo (Concizumab)

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

  • Product Details


    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 available in the following dosage forms:

    • 15 mg
    • 60 mg
    • 150 mg
    • 300 mg

    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.


    The active ingredient in Alhemo is concizumab.
