Flebogammadif bør ikke anvendes hos patienter, der kan være overfølsomme (allergiske) over for normalt humant immunglobulin eller andre af indholdsstofferne, eller hos patienter med allergi over for andre typer immunglobulin, navnlig hvis de har et meget lavt indhold af immunglobulin A (IgA) og danner antistoffer mod IgA.
Flebogammadif should not be used in people who may be allergic to normal human immunoglobulin or any of the other ingredients, or in patients who are allergic to other types of immunoglobulin, especially where they have deficiency (very low levels) of immunoglobulin A (IgA) and they have antibodies against IgA.
