Is there any side effects of immunoglobulin intravenous medication?

Possiby. Intravenous immunoglobulin (ivig) is a blood product collected from donations from hundreds of individuals, so there is the theoretical possibility of typical transfusion problems i.e. Infection, reaction etc. In the U.S. However production of this product is so controlled and processing involves, detergent washing and treating the product, so it is less likely to cause problems.
