IMPORTANT SAFETY INFORMATION
What is the most important information that I should know about HYQVIA?
- HYQVIA can cause blood clots.
- Call your healthcare professional (HCP) if you have pain, swelling, warmth, redness, or a lump in your legs or arms, other than at the infusion site(s), unexplained shortness of breath, chest pain or discomfort that worsens on deep breathing, unexplained rapid pulse, numbness or weakness on one side of the body.

- With your consent, your HCP may provide blood samples to Shire plc, to test for antibodies that may form against the hyaluronidase part of HYQVIA.
- Do not infuse HYQVIA into or around an infected or red swollen area because it can cause infection to spread.

Do not take HYQVIA if you:
- Are allergic to IgG, hyaluronidase, other blood products, or any ingredient in HYQVIA.

What should I tell my HCP before I start using HYQVIA?
