Warnings
Black Box Warnings
Acute renal dysfunction and renal failure
- Associated with renal dysfunction, acute renal failure, osmotic nephrosis, and death
- Administer IV at minimum concentration available and minimum rate of infusion in patients predisposed to acute renal failure; IVIG products containing sucrose as a stabilizer or at daily doses >400 mg/kg account for a disproportionate share of case reports involving renal failure
- Patients predisposed to acute renal failure
- Any degree of preexisting renal insufficiency
- Diabetes mellitus
- Age >65 years
- Volume depletion
- Sepsis
- Paraproteinemia
- Currently taking nephrotoxic drugs
Thrombosis
- Thrombosis may occur regardless of the route of administration
- Risk factors include: advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling central vascular catheters, hyperviscosity and cardiovascular risk factors
- Thrombosis may occur in the absence of known risk factors
- For patients at risk of thrombosis, administer at the minimum concentration available and at the minimum rate of infusion practicable
- Ensure adequate hydration in patients before administration
- Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity
Contraindications
Hypersensitivity to gamma globulin, thimerosal
Isolated IgA deficiency
Hyperprolinemia (Privigen)
Cautions
Risk of transmitting infectious agents (eg, viruses and theoretically, the Creutzfeldt-Jakob disease (CJD) agent); all infections thought by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider
Severe hypersensitivity reactions may occur; in case of hypersensitivity, discontinue the Privigen infusion immediately and institute appropriate treatment (see Contraindications)
Renal dysfunction, acute renal failure, osmotic nephrosis, and death may occur with immune globulin intravenous (IGIV) products in predisposed patients (see Black Box Warnings)
Aseptic meningitis syndrome (AMS) may occur infrequently following treatment with immune globulin products; discontinuation of treatment has resulted in remission of AMS within several days without sequelae; AMS usually begins within several hours to 2 days following IGIV treatment
Hyperproteinemia, increased serum viscosity, and hyponatremia may occur following treatment with IGIV products
Hemolytic anemia can develop subsequent to IGIV therapy due to enhanced RBC sequestration; IGIV recipients should be monitored for clinical signs and symptoms of hemolysis; if signs and/or symptoms of hemolysis are present after IGIV infusion, appropriate confirmatory laboratory testing should be done
Postpone live virus vaccines for at least 3 months
Maltose-containing brands may give false high for glucose in certain glucose-testing systems
Various passively transferred antibodies in immunoglobulin preparations may lead to misinterpretation of the results of serological testing
Transfusion-Related Acute Lung Injury (TRALI)
- Noncardiogenic pulmonary edema may occur following treatment with IGIV products TRALI is characterized by severe respiratory distress, pulmonary edema, hypoxemia, normal left ventricular function, and fever
- Symptoms typically appear within 1-6 hr following treatment; monitor patients for pulmonary adverse reactions
- If TRALI is suspected, perform appropriate tests for the presence of anti-neutrophil antibodies and anti-human leukocyte antigen (HLA) antibodies in both the product and the patient's serum
- TRALI may be managed using oxygen therapy with adequate ventilatory support
Pregnancy & Lactation
Pregnancy Category: C
Lactation: not known if excreted in breast milk
Pregnancy Categories
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
Pharmacology
Mechanism of Action
Pooled human immune globulins from donors used as replacement therapy for primary and secondary immunodeficiencies; may interfere with Fc receptors on the cells of the reticuloendothelial system for autoimmune disorders including cytopenias and ITP; may offer passive immunity by increasing antibody titer and antigen-antibody reaction potential
Pharmacokinetics
Half-Life: 14-40 days (varies greatly by patients)
Onset: Immediate
Duration: 1-3 months (variable)
Peak Plasma Time: 2.9 days (Gammagard, Hizentra); 2.5 days (Vivaglobin); 48 hr (IM serum)
Vd: 0.09-0.13 L/kg
Administration
IV Preparation
Dilution is dependent upon mfr & brand; do not shake, avoid foaming; discard unused portion
Iveegam EN: reconstitute with SWI; use immediately after reconstitution
Gammagard S/D, Polygam S/D: reconstitute with SWI; when diluted aseptically in a sterile laminar air flow hood, may store diluted solution under refrigeration for up to 24 hr; if reconstituted outside of laminar flow hood, use within 2 hr. Gammagard requires a filter, supplied by mfr.
Sandoglobulin: reconstitute with NS, D5W or SWI; when diluted aseptically in a sterile laminar flow hood, may store diluted solution under refrigeration for up to 24 hr

IV Administration
For initial treatment, a lower concentration and/or a slower rate of infusion should be used
Administer in separate infusion line from other medications; if using primary line, flush with saline prior administration
Decrease dose, rate &/or concentration of infusion in pts who may be at risk of renal failure
Decreasing rate or stopping the infusion may help relieve some adverse effects (flushing, changes in pulse rate, changes in blood pressure)
Epinephrine should be available during administration
