What is the most important information I should know about immune globulin (Gammagard, Gammaked, Gamunex-C)?

You should not use this medication if you have ever had an allergic reaction to an immune globulin, or if you have immune globulin A (IgA) deficiency with antibody to IgA.

Before using this medication, tell your doctor if you have kidney disease, heart disease, diabetes, hyperproteinemia (high levels of protein in the blood), paraproteinemia (abnormal proteins in the blood), a serious infection called sepsis, blood circulation problems or a blood vessel disorder, a history of stroke or blood clot, if you are on a low-salt diet, if you take diuretics, if you are 65 or older, or if you have been bed-ridden due to severe illness.
