Privigen 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 for lavt indhold af immunglobulin A (IgA) og danner antistoffer mod IgA.
Privigen 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 immunoglobulins, especially where they have deficiency (very low levels) of immunoglobulin A (IgA) and they have antibodies against IgA.
