Brand name(s)
Alphanate , Humate-P

This product contains human factor VIII (also called antihemophilic factor) and von Willebrand factor complex. Factors are proteins normally found in the blood that help the blood to thicken (clot) and stop any bleeding. People with low levels of factor VIII and von Willebrand factor are at risk for bleeding longer after an injury/surgery and for bleeding inside the body (especially into the joints and muscles). This product is used to temporarily replace the missing factors and reduce bleeding.

Different brands of this product have different amounts of these factors, and so have different uses. These products are not interchangeable. Do not change brands of this medication without the approval of your doctor. Some products are used to control and prevent bleeding episodes in people with low levels of factor VIII (hemophilia A). Some products are used to control and prevent bleeding episodes in people with low levels of von Willebrand factor (von Willebrand disease). Some products are used to prevent excessive bleeding during and after surgery in patients with von Willebrand disease.

This medication is given by slow injection into a vein as directed by your doctor. How fast you receive this medication depends on your dose and how you respond to it. See Side Effects section.

This medication is given in a hemophilia treatment center or hospital. In some cases, patients may be able to give this medication to themselves at home. If your doctor directs you to give this medication at home, read the product information available from your pharmacist before you start using this medication and each time you get a refill. Learn all preparation and usage instructions in the product package. If you have any questions, ask your health care professional.

If the medication and the solution used to mix it were refrigerated, bring both to room temperature before combining. After adding the solution to the powder, gently swirl the vial to completely dissolve the powder. Do not shake the vial. Before using, check this product for particles or discoloration. If either is present, do not use the liquid. After the medication is mixed, use right away.

The dosage is based on your medical condition, weight, blood test results, and response to treatment. Follow your doctor's instructions closely. Ask your doctor or pharmacist if you have any questions.
