Primary immunodeficiency syndromes1


The dose regimen should achieve a trough level of IgG (measured before the next infusion) of at least 5 to 6 g/l and aim to be within the reference interval of serum IgG for age

Loading dose (if required)

0.2 to 0.5g/kg. This may need to be divided over several days, with a maximal daily dose of 0.1 to 0.15 g/kg

Maintenance dose

After steady state IgG levels have been attained, maintenance doses are administered to reach a cumulative monthly dose of the order of 0.4-0.8 g/kg

Trough levels

Trough levels should be measured and assessed in conjunction with the incidence of infection

Dose adjustment

To reduce the rate of infection, it may be necessary to increase the dose and aim for higher trough levels

Secondary immunodeficiencies1

Recommended dose

The recommended dose administered at repeated intervals (approximately once per week) is to reach a cumulative monthly dose of the order of 0.2-0.4 g/kg.

Trough levels

IgG trough levels should be measured and assessed in conjunction with the incidence of infection

Dose adjustment

Dose should be adjusted as necessary to achieve optimal protection against infections, an increase may be necessary in patients with persisting infection; a dose decrease can be considered when the patient remains infection free
