去纤苷（去纤维钠）注意事项

Precautions for Defibrinoside (Defibrinated Sodium):

1. Defibrotide (Defibrotide Sodium) must be diluted before infusion. Prior to administration of defibrotide, confirm that the patient is not experiencing clinically significant bleeding and is hemodynamically stable on no more than one vasopressor.

2. Do not co-administer defibrotide (defibrotide sodium) with other intravenous drugs in the same intravenous line at the same time.

3. Bleeding: Defibrinoside increases the activity of plasmin in vitro, and sputum may increase the risk of bleeding after hematopoietic stem cell transplantation (HSCT) in patients with VOD. Do not initiate defibrotide in patients with active bleeding. Monitor patients for signs of bleeding. If bleeding occurs in a patient taking DEFITELIO, discontinue defibrotide, treat the cause, and provide supportive care until bleeding has stopped.

The concomitant use of defibrotide (defibrotide sodium) and a systemic anticoagulant or fibrinolytic therapy (excluding use for routine maintenance or central venous line reopening) may increase the risk of bleeding. Discontinue anticoagulants and fibrinolytic agents before defibrinoside (defibrinosodium) therapy, and consider delaying initiation of defibrotide (defibrinosodium) administration until the effects of the anticoagulant have lessened.

4. Hypersensitivity reaction: Hypersensitivity reactions have occurred in less than 2% of patients treated with defibrotide (sodium defibrotide). These reactions include rash, urticaria, and angioedema. One case of anaphylactic reaction was reported in a patient who had previously received defibrotide. Monitor patients for hypersensitivity reactions. Especially if there is a history of previous exposure. If a severe hypersensitivity reaction occurs, discontinue defibrination, treat with standard medical care, and monitor until symptoms resolve.

5. Special populations: Clinical studies of the elderly using defibrotide (sodium defibrotide) did not include a sufficient number of subjects aged 65 and above to determine whether their responses were different from those of younger subjects. Other reported clinical experiences did not identify differences in responses between older and younger patients.

6. Overdose: There are no known cases of overdose with defibrotide (sodium defibrotide). There are no known antitoxicants for defibrotide, and defibrotide is not dialyzable. If overdose occurs, initiate general supportive measures.
