Varicella Zoster Immune Globulin (Human) Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the clinical use of varicella zoster immune globulin during breastfeeding. Varicella zoster immune globulin is an immune globulin (IgG) rich in IgG antibodies against varicella zoster virus. IgG is a normal component of breastmilk that is likely to be partially destroyed in the infant's gastrointestinal tract and poorly absorbed by the infant during breastfeeding. Varicella zoster virus immune globulin can be given intramuscularly to infants weighing less than 2 kg. No special precautions are required during breastfeeding.
Drug Levels
Maternal Levels. Colostrum (3 days postpartum) and milk (7 days postpartum) samples from 2 mothers who were receiving intravenous immunoglobulin (IVIG) for the treatment of common variable immunodeficiency were studied. One mother was receiving 400 to 500 mg/kg of IVIG monthly and the other received 600 to 700 mg/kg of IVIG monthly. The time of the last dose before sample collection was not reported. Immune globulin G (IgG) concentrations were normal in the first mother's colostrum and milk and higher than normal in the colostrum of the second mother. IgM levels were normal in the colostrum and milk first mother and low in the second.[1]
