Subcutaneous IgG Therapy

Subcutaneous injections of gammaglobulin were used by Bruton to treat the first patient diagnosed with agammaglobulinemia, in the early 1950’s.

Subsequently, intramuscular (IM) injections of gammaglobulin were used in a large study in the United Kingdom and this became the standard route of administration of IgG for patients with antibody deficiencies.
