What is Privigen?

Privigen is a therapy that helps protect the health of PI patients by supplying their immune systems with antibodies to help prevent infections. By boosting levels of IgG, Privigen can help prevent serious and recurring infections and other complications in people with PI. Boosted IgG levels with Privigen can also help improve motor function in patients with CIDP. For people with chronic ITP, Privigen can raise platelet counts to help prevent bleeding.

  • The primary antibody found in Privigen is known as immunoglobulin G (IgG)
  • Your doctor may refer to your IgG treatment as "Ig," "intravenous Ig," or "IVIg"

How to take Privigen

Privigen comes in a small glass bottle and is given through a small needle into a vein, or "intravenously." It is administered by a nurse or doctor–whether you're at a hospital, clinic, physician's office, or in your home.

The Privigen difference–the first and only IVIg stabilized with proline

Unlike any other IVIg therapy, Privigen was specifically designed with proline to improve convenience and better preserve the immunoglobulin it's made of. Because of proline stabilization, Privigen:
