Dosing and Administration

CUVITRU® can be infused at the fastest rates or highest volumes with the fewest needlesticks of any SCIG, without sacrificing tolerability1,2

Clock icon.

How fast?

The median duration of once-weekly infusions was <1 hour (0.95 hours; range: 0.2-6.4 hours) in the North American clinical study.

  • CUVITRU may allow delivery of a full week’s dose in <15 minutes–with even shorter durations possible with more frequent dosing*
  • Approximately 94% of infusions were completed within 2 hours3

*If a patient is 75 kg (165 lb) and has been prescribed 36 g of IVIG per month, you could switch your patient to 12 g of CUVITRU weekly. After the first 2 infusions, subsequent infusions of CUVITRU could be completed in 15 minutes at a rate of 60 mL/h/site using 4 sites simultaneously.

What did this mean to patients?

  • Infuse at rates up to 60 mL/h/site in up to 4 sites simultaneously for a maximum total of 240 mL/h. Infuse first 2 infusions at 10 to 20 mL/h/site
  • With the highest infusion volume† (60 mL/h/site, as tolerated) compared to any other conventional SCIG option, a daily, weekly, or every-other-week infusion schedule is possible for your patients 
  • Your patients can create a treatment plan that meets their schedule

†Infuse first 2 infusions at 10 to 20 mL/h/site.

How few?

84.9% (N=4314) of infusions were administered using only 1 or 2 infusion sites (18.5%=1 site; 66.4%=2 sites) in the North American clinical study.

  • Infuse weekly in <1 hour in 1-2 sites
  • The use of more infusion sites may be beneficial for patients who want to reduce the volume administered per site or overall infusion duration

The dosing calculator is meant to be used as a tool to help HCPs make informed decisions about dosing. Takeda is not making dosing recommendations.

CUVITRU: Maximum volume per site is 60 mL/site as tolerated (except for the first 2 infusions for patients <40 kg, for whom the maximum volume is 20 mL/site). Maximum infusion rate is 60mL/h/site as tolerated (after first 2 infusions). Up to 4 sites can be used simultaneously.1

*Monthly dose of CUVITRU is equivalent to current monthly dose of SCIG.

*Monthly dose of CUVITRU is calculated based on a dose adjustment factor of 1.30.

This calculator does not represent every possible weight calculation. Weights begin as 24 lb and increase in 4 lb increments to 288 lb.

See Full Prescribing Information for additional dosage recommendations. A conversion factor of 2.2046 lb/kg is used to convert the patient’s weight to kilograms. The values displayed are rounded to the nearest decimal point.

Select CUVITRU vial combinations based on dosage

CUVITRU is available in 1 g, 2 g, 4 g, 8 g, and 10 g vials of IG 20%. The dose must be rounded up or down, based on the physician’s clinical judgement.
