Dosing Results
Infusion time*: XX hours and XX minutes Weekly dose XX g (XX mL)
Your results are based on a patient weight of XXX XX and dose of X.X g/kg

To see number of vials, select vial size:

10 g (50 mL)

Number of vials: XXX

*Infusion times can vary based on specific equipment used.

Formula used to calculate the weekly dose in mL from the patient's weight in kg:

For 0.2 g/kg dose (1:1 ratio)

Patient weight in kg = Weekly dose in mL

Example: 80 kg weight = Weekly dose of 80 mL

For 0.4 g/kg dose (1:2 ratio)

Patient weight in kg x 2 = Weekly dose in mL

Example: 80 kg weight = Weekly dose of 160 mL

Formula used to convert the weekly dose in mL to g:

Weekly dose in mL
= Weekly dose in g
Example: 80 mL = 16 g

Initiate therapy 1 week after last IVIg infusion

  • Recommended subcutaneous dose is 0.2g/kg (1 mL/kg) body weight (bw) per week
    • During PATH, both 0.2 g/kg and 0.4 g/kg doses were found to be safe and effective. Patients who relapsed were restabilized with IVIg
  • During the OLE study to PATH, patients who relapsed on 0.2 g/kg were titrated to 0.4 g/kg without IVIg restabilization

Proactively monitor and optimize therapy

  • Monitor the patient's clinical response and adjust the duration of therapy based on patient need
  • Volume and rate can be adjusted after initial infusion as tolerated, which may decrease infusion time and number of sites
  • Consider changing one variable at time (eg, rate, volume, ancillary supplies, site) to continue tailoring treatment for your patient
  • Hizentra may be infused in up to 8 infusion sites simultaneously, depending on volume

Administering Hizentra therapy

Hizentra should be administered subcutaneously only. Do not administer intravenously. Hizentra can be administered weekly for CIDP in 1 or 2 sessions over 1 or 2 consecutive days, using an infusion pump and relatively small needle(s).

Hizentra Injection Sites
  • A Hizentra dose may be infused into multiple injection sites. Use up to 8 sites per infusion. More than one infusion device can be used simultaneously. Infusion sites should be at least 2 inches apart. Change the actual site of infusion with each administration
  • Recommended infusion sites include the abdomen, thighs, upper arms, or side of upper leg/hip
  • SC needles are smaller than IV needles. Depending on a patient's size and weight, a needle as short as 4 mm or as long as 14 mm can be used

Encourage patients to start and stay on therapy

Information and resources are available to help patients manage their ongoing administration of Hizentra.
