Answer

Immune Globulins

Immunoglobulins are commonly used in admitted patients and rarely administered in the emergency department (ED).

IVIg is recommended for MG crisis, in patients with severe weakness poorly controlled with other agents, or in lieu of plasma exchange at a dose of 1 g/kg. IVIg is effective in moderate or severe MG worsening into crisis but does not exhibit value in mild disease. Data do not support or exclude a role for IVIg in chronic MG. The use of IVIg in a seronegative patient is not supported by the literature.

Immune globulin intravenous (Carimmune, Gammunex, Gammagard, Octagam)

High-dose IVIg successfully treats MG, though the mechanism of action is unknown. It is used in crisis management (eg, myasthenic crisis and the perioperative period) instead or in combination with plasmapheresis. Like plasmapheresis, it has a rapid onset of action, but the effects last only a short time.
