Chống chỉ định
Hypersensitivity. Selective immunoglobulin A (IgA) deficiency.
Thận trọng
Patient with predisposing factors to acute renal failure (e.g. sepsis, paraproteinaemia, diabetes mellitus, volume depletion, receiving nephrotoxic drugs), pre-existing factors for thrombotic events (e.g. hypertension, advanced age, history of vascular disease or thrombotic episodes, known or suspected hyperviscosity, impaired cardiac output, prolonged periods of immobilisation, severe hypovolaemia, acquired or inherited thrombophilic disorders). Obese patient. Patient naive to human Ig, switched from another human Ig product, or who had a long infusion interval since the previous one. Renal impairment. Pregnancy.
Phản ứng phụ
Significant: Hypersensitivity/anaphylactic reactions with hypotension; haemolytic anaemia, transfusion related acute lung injury (acute noncardiogenic pulmonary oedema), thromboembolic events (e.g. MI, stroke, DVT, pulmonary embolism), decreased neutrophil and/or neutropenia. Rarely, aseptic meningitis syndrome (high doses), acute renal impairment (including acute renal failure, increased serum creatinine, oliguria, osmotic nephrosis), haemolysis.
Gastrointestinal disorders: Nausea, vomiting.
General disorders and administration site conditions: Chills, fatigue, pyrexia.
Investigations: Increased BUN.
Musculoskeletal and connective tissue disorders: Arthralgia, back pain, muscle cramps.
Nervous system disorders: Headache, dizziness.
Respiratory, thoracic and mediastinal disorders: Wheezing.
Skin and subcutaneous tissue disorders: Rash, pruritus, drug eruption, erythema.
Vascular disorders: Flushing.
IV/Parenteral: C
MonitoringParameters
Assess for volume depletion prior to therapy. Monitor urine output; renal function (e.g. BUN, serum creatinine prior to initiation and periodically thereafter); vital signs including blood pressure (during infusion); blood viscosity at baseline (in at-risk patients). Check for the presence of antineutrophil antibodies (if clinically indicated). Assess for signs and symptoms of anaphylactic reactions, infusion-related reactions (during and after infusion), and haemolytic anaemia.
Tương tác
May diminish the therapeutic effect of live vaccines (e.g. measles, mumps, rubella, varicella vaccines).
Lab Interference
May cause false-positive results in serological tests (e.g. direct Coombs test).
Tác dụng

Excretion: Elimination half-life: 8-24 days.
Bảo quản
