Does Hy make a difference? Absolutely.

Hyaluronidase is the reason you can infuse once a month* and what makes HyQvia different. Technically, it’s Recombinant Human Hyaluronidase, but you can call it Hy. We do. Hy is something found in your body naturally. It’s the first part of your two-part infusion. It temporarily opens the space under your skin (the subQ space), allowing a larger amount of Ig to reach your subQ tissue and be absorbed into your bloodstream to help HyQvia fight infections. So you don’t have to infuse as many times per month. Kind of awesome, right?

In the clinical trials, there were no observable changes in the skin or subQ tissue in almost 3,000 infusions and maximum exposure of over 3 years. After a HyQvia infusion, a temporary, soft swelling may occur around the infusion site, which may last 1 to 3 days due to the volume of fluid infused. The effect of Hy is reversible and your skin will be restored within 24 to 48 hours following your infusion. Learn about additional side effects that can occur with HyQvia.

*Every 3 or 4 weeks.

Dual-vial unit.
One infusion.

HyQvia is supplied as a dual-vial unit that allows you to infuse Hy, then Ig, at the same time. You can work with your doctor to use one or two infusion sites, depending on what’s right for you. Ready to learn more about infusing HyQvia?
