About this Medication
What the medication is used for
KOGENATE FS (Antihemophilic Factor [Recombinant]) is used for the treatment of hemophilia A. Patients who have hemophilia A do not have enough clotting Factor VIII, which helps control bleeding. KOGENATE FS can be used to prevent bleeding before it happens, or it can be used to stop a bleeding episode that has already begun in patients who have hemophilia A.
When used as a regular prophylactic treatment, KOGENATE FS is indicated to prevent the occurrence of spontaneous hemorrhagic episodes and to prevent joint damage in children. KOGENATE FS is also indicated to prevent and control bleeding in adults with hemophilia A when used regularly.
What it does
KOGENATE FS is clotting Factor VIII that has been developed in the laboratory. It is very similar to the Factor VIII that occurs naturally in human blood. In patients with hemophilia A, who do not have enough natural Factor VIII in their blood, KOGENATE FS gives them additional Factor VIII to help prevent and/or control bleeding. KOGENATE FS is given directly into the blood through an injection in a vein.
When it should not be used
KOGENATE FS does not contain von Willebrand Factor and therefore, is not indicated for the treatment of von Willebrand disease.

Warnings and Precautions
Serious warnings and precautions
Some people can develop inhibitors to treatment with Factor VIII.
Inhibitors to treatment with Factor VIII are antibodies than can reduce the effectiveness of treatment. Anyone can develop inhibitors, but they are especially common in young children with severe hemophilia during their first years of treatment and any patient who has had little previous treatment with Factor VIII. Your hemophilia healthcare team will monitor you carefully for the development of inhibitors.
Be careful when handling the administration set and needle, to minimize the possibility of accidental needlestick injuries. Contact your healthcare team immediately if you accidentally injure yourself.
Rarely, some people have allergic reactions to Factor VIII. If you develop low blood pressure, a rash, hives, wheezing or tightness in your chest, seek immediate emergency treatment.
BEFORE you use KOGENATE FS talk to your doctor or pharmacist if
- you are allergic to mouse or hamster protein, or any of the ingredients in KOGENATE FS.
- you have had inhibitor development in the past.
- you have been told you have heart disease or are at risk for heart disease.
- you are pregnant, are trying to become pregnant or are a nursing mother.

Proper Use of this Medication
Your doctor will calculate the best dosage for you, based on your weight, blood tests of your Factor VIII level, and whether KOGENATE FS is being used to prevent or stop a bleeding episode. You and your healthcare team will work together to find out what dosage and schedule works best for you.

- A major/very serious bleeding episode will be treated with 40-50 IU for every kilogram of body weight.
- Surgical procedures may require 50 IU for every kilogram of body weight before the operation. You may also receive treatment presurgery by an initial bolus (all at once) injection followed immediately by continuous infusion.
- Patients who have inhibitors may require higher dosages.
- The regular prophylaxis schedule for children is 25 IU/kg of body weight every other day.
- The regular prophylaxis schedule for adults is 25 IU/kg of body weight three times per week.
No symptoms of overdose have been reported.
Side Effects and what to do about them
In patients who have had previous treatment with Factor VIII, some side effects included reactions at the injection site, rash, and itchy skin.
In patients who had no previous treatment with Factor VIII, some side effects included formation of inhibitors to Factor VIII, reactions at the injection site, rash, and itchy skin.
You may find that more KOGENATE FS is required than estimated to stop the bleeding (lack of effect).
If you are concerned about any possible side effects, talk to your doctor.
