High infusion rate may increased risk of adverse reactions. Ensure adequate hydration prior to IV infusion of immunoglobulin. Monitor urine output and serum creatinine levels during treatment. Avoid concurrent use of loop diuretics during IV infusion of immunoglobulin. Live vaccines should generally be given 3 wk before or 3 mth after admin of normal immunoglobulin. Different formulations and brands of human normal immunoglobulins may not be equivalent, thus individual literature should be consulted. Pregnancy and lactation.

Mode of Action
Human normal immunoglobulin is derived from donations of pooled human plasma. It contains antibodies, mainly immunoglobulin G (IgG), to various bacteria and viruses present in the general population such as hepatitis A, measles, mumps, rubella and varicella. It has a distribution of IgG subclasses that is very close to that of the normal human plasma. It is therefore, used to provide passive immunisation against such diseases.
