Gamunex, Immune Globulin Intravenous (Human), 10% Caprylate/Chromatography Purified, is indicated as
replacement therapy of primary humoral immunodeficiency disease (PI) and as immunomodulatory therapy for
idiopathic thrombocytopenic purpura (ITP). Gamunex is contraindicated in individuals with known anaphylactic or
severe systemic response to Immune Globulin (Human).
Immune Globulin Intravenous (Human) products have been reported to be associated with renal dysfunction, acute
renal failure, osmotic nephrosis and death. Patients should be instructed to immediately report symptoms of
decreased urine output, sudden weight gain, fluid retention/edema, and/or shortness of breath (which may suggest
kidney damage) to their physicians.
While these reports of renal dysfunction and acute renal failure have been associated with the use of many of the
licensed IGIV products, those containing sucrose as a stabilizer accounted for a disproportionate share of the total
number. Gamunex does not contain sucrose. Glycine, a natural amino acid, is used as a stablizer.
There have been reports of noncardiogenic pulmonary edema, rare reports of hemolytic anemia, and very rare reports
of aseptic meningitis in patients administered with IGIV. Thrombotic events have been reported in association with
IGIV. Patients at risk may include those with a history of atherosclerosis, multiple cardiovascular risk factors,
advanced age, impaired cardiac output, and/or known or suspected hyperviscosity. As with all plasma-derived
therapeutics, the potential to transmit infectious agents cannot be totally eliminated.
Gamunex is made from human plasma. Products made from human plasma may contain infectious agents, such as
viruses, that can cause disease. The risk that such products will transmit an infectious agent has been reduced by
screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus
infections, and by inactivating and/or removing certain viruses. Despite these measures, such products can still
potentially transmit disease. There is also the possibility that unknown infectious agents may be present in such
products. Individuals who receive infusions of blood or plasma products may develop signs and/or symptoms of
some viral infections, particularly hepatitis C.
