Generic Name: factor VIII, human plasma derived
Brand Names: Monoclate-P, Hemofil M, Koate DVI, Antihemophilic Factor (Human)
Drug Class: Coagulation Factors, Hemostatics
What is factor VIII, human plasma derived, and what is it used for?
Factor VIII, human plasma-derived is a specialized protein in blood that plays a role in the clotting (coagulation) process. Deficiency in factor VIII can lead to uncontrolled bleeding even with minor injuries. Coagulation factor VIII is obtained by isolating it from the plasma and purifying it. Plasma is the liquid component of blood that serves as the medium for transporting all the blood components including blood cells, enzymes, gases, and nutrients to all the organs and the metabolic wastes for elimination through the lungs and kidneys.
Human plasma-derived factor VIII is used to maintain the necessary levels of the particular factor in individuals with hemophilia A, a hereditary bleeding disorder caused by deficiency in factor VIII. Factor VIII is infused in hemophilia A patients after an injury to increase its levels and prior to surgical procedures to prevent excessive bleeding.
Factor VIII used for infusion is a highly purified concentrate of factor VIII: C, the coagulant portion of the factor VIII complex. Factor VIII: C acts as a cofactor to factor IX and the two together activate factor X and the cascade of the coagulation process for the formation of a blood clot, including conversion of prothrombin to thrombin, aggregation of platelets and conversion of fibrinogen to fibrin, the tough protein that forms the scaffolding for the blood clot.
- Do not administer human plasma-derived factor VIII to patients with known hypersensitivity to mouse protein.
- The factor VIII solution must be administered at a rate of less than 10 mL/minute.
- The risk of a blood clot blocking a blood vessel (thromboembolic event) increases with each administration of factor VIII.
- Patients may develop neutralizing antibodies to factor VIII.
- Dose requirements will vary in patients with factor VIII inhibitors, adjust accordingly.
- Although factor VIII is derived from donor plasma that is screened for viral and other diseases that can be transmitted and undergo a process for further reducing the risk of viral infections, all plasma products still carry a potential for viral infections. Apprise patients of the risk of infection and the symptoms to watch for, and advise them to report symptoms immediately.

It is important to always tell your doctor, pharmacist, or health care provider about all prescription and over-the-counter medications you use, as well as the dosage for each, and keep a list of the information. Check with your doctor or healthcare provider if you have any questions about the medication.
Pregnancy and breastfeeding
- Factor VIII levels should be closely monitored during pregnancy because pregnant hemophilia A patients have an increased risk for bleeding with invasive procedures, spontaneous miscarriage, pregnancy termination, and delivery.
- There are no animal reproductive studies and it is not known if factor VIII, human plasma-derived, can cause fetal harm. Factor VIII should be used in pregnant women only if maternal benefits justify the risks to the fetus.
- It is not known if factor VIII administered to a nursing mother is excreted in breastmilk. Use with caution.
What else should I know about factor VIII, human plasma derived?
- Report to your physician immediately if you develop:
- Hypersensitivity symptoms such as hives, wheezing, tightness of chest, low blood pressure (hypotension), or anaphylaxis.

- Symptoms of hepatitis A infection such as poor appetite, tiredness, low-grade fever, nausea, vomiting, abdominal pain, dark urine, and yellowing of skin.

Bilirubin is a waste product of the normal breakdown of red blood cells in the liver. Normal bilirubin levels vary from lab to lab, and range from around 0.2 to 1.2 mg/dL. High levels of bilirubin can be diagnosed with a bilirubin blood test. Causes of elevated levels of bilirubin in the blood can be caused by infections, viral hepatitis, anemia, genetic diseases, and liver problems. Symptoms of elevated bilirubin levels depend on the cause; however, jaundice is a common sign. Treatment for elevated bilirubin levels depend on the cause.

Hemophilia is defined as one of a group of inherited bleeding disorders. Hemophilia A and hemophilia B are inherited in an X-linked recessive genetic pattern. Symptoms of hemophilia include bleeding into the: joints, muscles, GI or urinary tract, or brain or skull. Hemophilia treatment generally involves the replacement of blood clotting factors.
How Serious Is a Blood Clot in the Lungs?
A blood clot is a solid or semisolid clump of blood. When the tissues of our body are injured, excessive blood loss is prevented by the clotting of blood. When a blood clot occurs inside the blood vessels it may lead to serious medical conditions. When a blood clot occurs inside the arteries to the lungs, the condition is called pulmonary embolism (PE).

How Do You Know If You Have a Blood Clot in Your Leg?
Blood clots are clumps of blood formed when the blood changes from a fluid to a semisolid form. When a blood clot is formed in one of the large veins in the legs or arms, the condition is called deep vein thrombosis (DVT). A blot clot in your leg can hamper the flow of oxygen and nutrients to the affected area. An untreated DVT may cause the clot to grow bigger and break in small pieces that can travel to other organs, such as the heart and lungs, causing serious consequences.
Varices are dilated blood vessels usually in the esophagus or stomach. Symptoms of bleeding varices include vomiting blood, black stools, low blood pressure, shock, and rapid heart rate. Bleeding varices are a medical emergency. Treatment may involve liver transplant, devascularization, distal splenorenal shunt, banding, sclerotherapy, or transjugular intrahepatic protosystemic shunt.
What Are the 3 Types of Hemophilia?
Hemophilia is a rare bleeding disorder in which the blood doesn't clot normally. It mainly affects males and is rare in females. Hemophilia is sometimes called “the royal disease.” Several royal families of England, Germany, Russia, and Spain in the 19th and 20th centuries had members afflicted with hemophilia.
What Is High Blood Pressure (Hypertension)?
High blood pressure or hypertension is when the blood pressure readings consistently range from 140 or higher for systolic or 90 or higher for diastolic. Blood pressure readings above 180/120 mmHg are dangerously high and require immediate medical attention.
What Are the 5 Main Blood Tests?

What Does a Blood Clot Feel Like?
Blood clots are semi-solid masses of blood that may be immobile (thrombosis) and impede blood flow or dislodge to other parts of the body (embolism). Deep vein clots, if dislodged, can travel through veins through the lungs to the arteries in the lungs. This is referred to as a pulmonary embolism and can be deadly. Blood clots can also lead to a heart attack or stroke.

Normal blood pressure is when the pressure is less than or upto 120/80 mmHg. The value 120 denotes the systolic pressure, and the value 80 denotes the diastolic pressure.
