About Hizentra

What's the difference between intravenous Ig (IVIg) therapy and subcutaneous Ig (SCIg) therapy?

Ig therapy is generally delivered in one of two ways. Intravenous Ig therapy, or IVIg, is administered into the vein by a medical professional. Patients with PI typically receive IVIg once every 3-4 weeks. Maintenance IVIG therapy for CIDP is often administered once every 3 weeks.

Subcutaneous Ig therapy, or SCIg, is infused in the fatty layer under the skin (not in a vein). It uses a relatively small needle and an infusion pump. With proper training, most patients can self-infuse SCIg (or be assisted by a caregiver). Most SCIg products are infused weekly, as Hizentra is for CIDP, but for those with PI, Hizentra provides the option to infuse as often as daily or up to once every 2 weeks. Talk with your healthcare provider about the dosing option that's right for you.

What are the benefits of a 20% Ig concentration?

As a 20% Ig therapy, Hizentra has the highest concentration of immunoglobulin available in a SCIg treatment, so you can receive the IgG treatment while infusing a lower volume, which potentially could result in fewer needlesticks. Hizentra was specifically designed to deliver Ig levels in half the volume of 10% Ig products,* regardless of which dosing schedule you and your healthcare provider choose.

*Based on an equivalent dose in grams.

How long can I store Hizentra at room temperature?

Hizentra can be stored at room temperature (up to 25°C [77°F]) for up to 30 months, up to the expiration date printed on the outer carton of the prefilled syringe or vial label. This means you don't have to worry about refrigerating Hizentra when you are on the go.

Will the amount of medicine I take or the time it takes to infuse change based on my infusion schedule?

The amount of Hizentra you infuse per month will not change, regardless of how often you infuse.

How long each infusion takes may vary based on a number of factors, including how often you infuse, the number of infusion sites you use, your infusion rate, and other factors. You and your doctor can decide what is best for you.

For PI, you can have infusions as often as every day up to every 2 weeks.

For CIDP, infusions are given once weekly (in 1-2 sessions over 1-2 consecutive days).

What kinds of side effects are associated with Hizentra?

The most common side effects in the clinical trials for Hizentra include redness, swelling, itching, and/or bruising at the infusion site; headache; chest, joint or back pain; diarrhea; tiredness; cough; rash; itching; fever, nausea, and vomiting. These are not the only side effects possible. Tell your doctor about any side effect that bothers you or does not go away.

What dosage forms does Hizentra come in?

Only Hizentra offers the choice between prefilled syringes and vials. Hizentra is the first and only Ig available in prefilled syringes. While vials are still available to all patients, prefilled syringes may be a more convenient option for some people. Your doctor can help you decide whether prefilled syringes are right for you.


How often will I infuse Hizentra?

That depends on the schedule that you and your doctor decide is best for you. Hizentra gives you protection with weekly dosing (1-2 sessions over 1-2 consecutive days) for CIDP. Dosing options for PI range from once a day to once every 2 weeks.

You and your doctor can choose your Hizentra dosing treatment plan based on:

  • Your routine
  • How much medicine per infusion
  • How long infusions take
  • How many infusion sites

Learn how you and your doctor can personalize your dosing and administration

How many infusion sites can I use with Hizentra?

A Hizentra dose may be infused into as many as 8 infusion sites simultaneously. In clinical trials, PI patients generally used 4 or fewer infusion sites per infusion, while CIDP patients most often used 4. The number and location of infusion sites depend on the volume of the total dose. Infusion sites should be at least 2 inches apart. Change the actual site of infusion with each administration. New sites should be at least 1 inch from previous site. Recommended infusion sites include the thighs, upper arms, abdomen, and side of upper leg/hip.

Can I self-administer Hizentra?

Most patients/caregivers can be trained to infuse. However, self-administration should be done only after you go through training and perform a successful demonstration in front of a healthcare professional. You can always ask your healthcare professional questions about self-administration, especially if you need a refresher or if your infusion regimen has recently changed.

Learn how to self-administer

When you sign up for Premier StartSM, you may be able to receive a 4-week supply of Hizentra and infusion equipment at no cost to you, plus free at-home visits by a trained nurse to help you learn to infuse.

Review tips for getting started

After I am trained on self-administration, will I still need to go to my healthcare provider?

Yes. Partnering with one's healthcare provider is necessary for patients receiving Ig treatment. Regular visits with your healthcare provider are an important part of your therapy program. At each visit, your healthcare provider will evaluate your dose and your response to treatment and address any concerns you may have. It's important to bring your Hizentra therapy journal or send infusion records via the Hizentra app to share with your healthcare provider.

Can I switch from IVIg to any of the possible Hizentra dosing schedules?

Talk with your healthcare provider about which option is best for you. For CIDP, the recommended dosing schedule is weekly. For PI, several dosing schedules (from daily to once every 2 weeks) are available, and your doctor will work with you to find the dosing schedule that works best for you.

Review tips for getting started

How long does it take to infuse?

The median infusion time based on the clinical trials was about 1.5–2 hours for PI, and about 1 hour for CIDP. Your infusion time may be shorter or longer, depending on the dose and frequency your healthcare provider has prescribed for you. Your experience may vary depending on a number of factors, including number of infusion sites, tubing, and how well you tolerate the treatment.

At what rate and volume do you infuse Hizentra?

For PI patients

Your initial rate should not exceed 15 mL/hour/site, but can then be increased to 25 mL/hour/site depending on how you feel. Your initial volume per site should not exceed 15 mL/site, but can then be increased up to 25 mL/site depending on how you feel.

For CIDP patients

Your initial rate should not exceed 20 mL/hour/site, but can then be increased to 50 mL/hour/site depending on how you feel. Your initial volume per site should not exceed 20 mL/site, but can then be increased up to 50 mL/site depending on how you feel.
