Evithrom
Generic name: human thrombin
Warnings and Precautions
- May carry a risk of transmitting infectious agents such as viruses and theoretically, the Creutzfeldt-Jakob disease (CJD) agent, despite manufacturing steps designed to reduce the risk of viral transmission.
- Potential risk of thrombosis if absorbed systemically.
- Anaphylactic reactions may occur.
- Adverse events were reported in the clinical trial with similar frequency in the two study groups (Evithrom or bovine thrombin group). The most common adverse event reported was procedural complications and pruritus. None of the adverse events reported was considered causally related to Evithrom administration.
- Immunogenicity was evaluated by testing for the development of antibodies to highly purified antigens: human thrombin, human Factor V/Va, bovine thrombin and bovine Factor V/Va. None of the patients treated with Evithrom developed antibodies to human thrombin or to human Factor V/Va.
To report SUSPECTED ADVERSE REACTIONS, contact ETHICON Customer Support Center at (877) 384-4266 or FDA at 1-800-FDA-1088 or http://www.fda.gov/medwatch.
- Geriatrics: No differences in safety or effectiveness were observed between the elderly and younger patients. Greater susceptibility of older patients to adverse reactions cannot be ruled out.
Some viruses such as hepatitis A virus and parvovirus B19 are particularly difficult to remove or inactivate. Parvovirus B19 most seriously affects pregnant women or immune-compromised individuals. Symptoms of parvovirus B19 infection include: fever, drowsiness, chills and runny nose followed about two weeks later by a rash and joint pain. Evidence of hepatitis A may include several days to weeks of poor appetite, fatigue and low-grade fever followed by nausea, vomiting and abdominal pain. Dark urine and a yellowed complexion are also common symptoms. Patients should be encouraged to consult their physician if such symptoms appear. If absorbed systemically Evithrom could potentially cause blood clotting disorders. Patients should be encouraged to consult their physician for any new or unusual symptoms.
