Your Kogenate® FS, Antihemophilic Factor (Recombinant), questions – answered
This Q&A summarizes important information about Kogenate FS. Please read it carefully before using this medicine. This information does not take the place of talking with your healthcare provider, and it does not include all of the important information about Kogenate FS. If you have any questions after reading this, ask your healthcare provider.
Kogenate FS is a medicine used to replace clotting factor (factor VIII or antihemophilic factor) that is missing in people with hemophilia A (also called "classic" hemophilia). Hemophilia A is an inherited bleeding disorder that prevents blood from clotting normally.
Kogenate FS is used to treat and control bleeding in adults and children with hemophilia A. Your healthcare provider may give you Kogenate FS when you have surgery. Kogenate FS can reduce the number of bleeding episodes in adults and children when used regularly (prophylaxis). Kogenate FS can reduce the risk of joint damage in children without pre-existing joint damage when used regularly.
Kogenate FS is not used to treat von Willebrand Disease.
You should not use Kogenate FS if you:
- Are allergic to rodents (like mice and hamsters).
- Are allergic to any ingredients in Kogenate FS.
Tell your healthcare provider if you are pregnant or breastfeeding because Kogenate FS may not be right for you.
Tell your healthcare provider about all of your medical conditions.
Tell your healthcare provider and pharmacist about all of the medicines you take, including all prescription and non-prescription medicines, such as over-the-counter medicines, supplements or herbal remedies.
Tell your healthcare provider if you have been told you have heart disease or are at risk for heart disease.
Tell your healthcare provider if you have been told that you have inhibitors to factor VIII (because Kogenate FS may not work for you).
You could have an allergic reaction to Kogenate FS. Call your healthcare provider right away and stop treatment if you get:
- Rash or hives
- Tightness of the chest or throat
- Difficulty breathing
- Light-headed, dizziness
- Decrease in blood pressure
Your body can also make antibodies, called "inhibitors," against Kogenate FS, which may stop Kogenate FS from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests for the development of inhibitors to factor VIII.
Other common side effects of Kogenate FS are:
- Local injection site reactions (pain, swelling, irritation at infusion site)
- Infections from implanted injection device
Tell your healthcare provider about any side effect that bothers you or does not go away.
Finding veins for injections may be difficult in young children. When frequent injections are required, your child's healthcare provider may propose to have a device surgically placed under the skin to facilitate access to the bloodstream. These devices may result in infections.
These are not all the possible side effects with Kogenate FS. You can ask your healthcare provider for information that is written for healthcare professionals.
