KIOVIG må ikke anvendes af patienter, der kan være overfølsomme (allergiske) over for normalt humant immunoglobulin eller andre af indholdsstofferne, eller af patienter, som er allergiske over for andre former for immunoglobulin, især hvis de har mangel (meget lave niveauer) på immunoglobulin A (IgA) eller hvis de har antistoffer mod IgA.
Kiovig should not be used in people who may be hypersensitive (allergic) to human normal 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.
