Hizentra is an Ig* therapy that provides proven PI protection with the convenience of self-administration, so you can focus on everyday living


When treating PI, what's the difference between Hizentra and intravenous Ig (IVIg)?

With Hizentra, an IV is not involved. Hizentra treats primary immune deficiency (PI) with subcutaneous infusions, which means you can self-administer by infusing just under the skin, not into a vein, after receiving training from your doctor.

Hizentra gives you steady Ig levels for consistent PI protection, with less volume per dose plus flexible dosing options to fit your lifestyle (from daily to once every 2 weeks).

Hizentra is a prescription medicine used to treat PI in patients 2 years and older.
