Precautions

Before administering antihemophilic factor (recombinant),

• tell your doctor and pharmacist if you have ever had a reaction to an antihemophilic factor or if you are allergic to any drugs.
• tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially aminocaproic acid (Amicar), anticoagulants ('blood thinners') such as warfarin (Coumadin), corticosteroids (e.g., prednisone), cyclophosphamide (Cytoxan), cyclosporine (Neoral, Sandimmune), heparin or low-molecular-weight heparin (Lovenox, Normiflo), interferon alfa (Roferon-A, Intron), vincristine (Oncovin), vitamin K, and other vitamins.
• tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking antihemophilic factor (recombinant), call your doctor.
• if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking antihemophilic factor (recombinant), before any surgeries or procedures.

Administering your medication

Before you administer antihemophilic factor (recombinant), look at the solution closely. It should be clear and free of floating material. Gently squeeze the bag or observe the solution container to make sure there are no leaks. Do not use the solution if it is discolored, if it contains particles, or if the bag or container leaks. Use a new solution, but show the damaged one to your health care provider.

It is important that you use your medication exactly as directed. Do not stop your therapy on your own for any reason. Do not change your dosing schedule without talking to your health care provider. Your health care provider may tell you to stop your infusion if you have a mechanical problem (such as a blockage in the tubing, needle, or catheter); if you have to stop an infusion, call your health care provider immediately so your therapy can continue.
