Vivaglobin
SIDE EFFECTS
In clinical studies, administration of Immune Globulin Subcutaneous (Human), VivaglobinÃ? has been shown to be safe and well tolerated in both adult and pediatric subjects. Reactions similar to those reported with administration of other immune globulin products may also occur with VivaglobinÃ?. Rarely, immediate anaphylactoid and hypersensitivity reactions may occur. In exceptional cases, sensitization to IgA may result in an anaphylactic reaction (see CONTRAINDICATIONS).
Should evidence of an acute hypersensitivity reaction be observed, the infusion should be stopped promptly, and appropriate treatment and supportive therapy should be administered.
In the US and Canada clinical study, the safety of VivaglobinÃ? was evaluated for 15 months (3Âmonth wash-in/wash-out period followed by 12-month efficacy period) in 65 subjects with PID. The most frequent adverse reaction was local reaction at the injection site. Table 5 summarizes the most frequent adverse events by subject reported in the clinical study, and Table 6 summarizes the most frequent adverse events by infusion.

In the non-IND Europe and Brazil clinical study, the safety of VivaglobinÃ? was evaluated for 10 months in 60 subjects with PID. The adverse events and their rates reported in this study were similar to those reported in the US and Canada study, with two notable exceptions for the related adverse events. These events were 59 episodes of headache (1.6%) and 2 episodes of fever (0.1%) in the US and Canada study and no episodes of headache and 18 episodes of fever (0.8%) in the Europe and Brazil study.
Local (Injection Site) Reactions
Local injection site reactions consisting of mostly mild or moderate swelling, redness and itching, have been observed with the use of VivaglobinÃ?. No serious local site reactions were observed. The majority of injection site reactions resolved within four days. Additionally, the number of subjects reporting local injection site reactions decreased substantially after repeated use (see Figure 1). Only three subjects in the US and Canada study and one subject in the Europe and Brazil study discontinued due to local site reactions.

DRUG INTERACTIONS
Immunoglobulin administration can transiently impair the efficacy of live attenuated virus vaccines such as measles, mumps and rubella. The immunizing physician should be informed of recent therapy with Immune Globulin Subcutaneous (Human), VivaglobinÃ?, so that appropriate precautions can be taken.
VivaglobinÃ? should not be mixed with other medicinal products.
