Recombinant Antihemophilic Factor Viii
About Recombinant Antihemophilic Factor Viii
Recombinant Antihemophilic Factor Viii is an injectable medicine used to manage haemophilia A, a genetic disorder where the blood does not clot normally. It is used to prevent and control bleeding episodes, especially in joints and muscles, by replacing a missing natural clotting protein in the blood. This medicine helps restore the body's natural ability to form blood clots and stop bleeding.
The frequency of your injections depends on whether you use it to prevent bleeding or treat active bleeds, but consistency is key to keeping clotting levels stable. Since it is injected directly into a vein, it can be used without regard to meals. To support your treatment, maintaining a healthy weight and staying hydrated are highly recommended to keep your veins healthy.
While using Recombinant Antihemophilic Factor Viii, you may notice mild side effects such as redness at the injection site, minor headaches, or a temporary fever. However, you must seek medical attention immediately if you experience chest tightness, skin rashes, or if your bleeding continues despite injecting the medication.
Talk to your doctor before starting this medicine if you have any pre-existing heart conditions or a history of blood clots. Do not take this if you have a known, severe allergy to this medication or any proteins derived from hamsters or mice, which are sometimes used during the manufacturing process.
Let your doctor know about other medications you take, especially blood thinners or aspirin, as they can interfere with how your blood clots and increase bleeding risks. Avoid heavy alcohol use as it can affect overall health and liver function, which plays a role in clotting. If you are pregnant, breastfeeding, or an older adult, consult your healthcare provider to ensure this treatment is safe for your specific situation.

Habit Forming
Diet & Lifestyle Advise
- Maintain a healthy weight: Extra body weight puts added stress on your knees, hips, and ankles, which can increase the risk of joint bleeds.
- Choose low-impact exercises: Activities like swimming, walking, and stationary cycling build strong muscles to support your joints without the high risk of injury from contact sports.
- Prioritise dental hygiene: Regular brushing, flossing, and dental checkups prevent gum disease, reducing the risk of bleeding during dental visits.
- Protect your body: Wear protective gear during physical activities and keep your home free of hazards that could cause slips or falls.
Special Advise
- Please ensure the serum sodium concentration is normal before starting or resuming the desmopressin injection.
- Regular monitoring of electrolytes is essential to rule out chances of fluid imbalance.
- Your doctor may advise kidney functioning tests to monitor for renal impairment.
- Frequent monitoring of plasma factor VIII activity levels will be suggested during the treatment period to ensure adequate factor VIII levels have been achieved.
Patients Concern
Disease/Condition Glossary
Hemophilia A: Also known as classical haemophilia. It is an inherited bleeding disorder in which the blood does not clot normally. It mainly occurs due to the congenital lack of coagulation factor VIII. Symptoms include unusual bleeding after vaccinations, large or deep bruises, joint pain and swelling, and blood in urine or stool.
