Immune thrombocytopenic purpura IV only: total dose 2 g/kg given as 1 g/kg on two consecutive days or 0.4 g/kg on five consecutive days; do not administer subcutaneously.
Polyradiculoneuropathy, Chronic Inflammatory Demyelinating IV only: loading dose 2 g/kg over two to four consecutive days; maintenance 1 g/kg every 3 weeks (or 0.5 g/kg on two consecutive days every 3 weeks).
Common Variable Immunodeficiency, X-linked agammaglobulinemia, Congenital agammaglobulinemia, Wiskott-Aldrich Syndrome, Severe Combined Immunodeficiency 300 to 600 mg/kg SC every 3 to 4 weeks after initial ramp-up from 1-week to full dose; rHuPH20 at 80 U/g IgG infused immediately before each IgG dose at each infusion site.
Polyradiculoneuropathy, Chronic Inflammatory Demyelinating Same dose and frequency as prior IGIV treatment SC, typical dosing interval 4 weeks; rHuPH20 at 80 U/g IgG infused immediately before each IgG dose; ramp-up recommended based on tolerability.
Contraindications

Pharmacology
GAMMAKED is an immune globulin that supplies a broad spectrum of opsonic and neutralizing IgG antibodies against bacterial, viral, parasitic, and mycoplasmal agents and their toxins; the precise mechanism of action in ITP and CIDP has not been fully elucidated.
Immune globulin (IgG) replacement product in which the Immune Globulin Infusion (Human), 10% supplies broad-spectrum opsonizing and neutralizing IgG antibodies against bacterial and viral agents, while rHuPH20 transiently depolymerizes subcutaneous hyaluronan to increase tissue permeability, facilitating dispersion and absorption of the full IgG dose administered subcutaneously.
