The recommended dosage of KORSUVA is 0.5 mcg/kg administered by intravenous bolus injection into the venous line of the dialysis circuit at the end of each HD treatment [see Dosage and Administration (2.3)].

Preparation Instructions

Do not mix or dilute KORSUVA prior to administration.
Inspect KORSUVA for particulate matter and discoloration prior to administration. The solution should be clear and colorless. Do not use KORSUVA vials if particulate matter or discoloration is observed.
KORSUVA is supplied in a single-dose vial. Discard any unused product.
Injection volume to be administered is determined by patient’s target dry body weight in kilograms (one patient may use less than the full contents of the vial or use more than one vial). See Table 1.

Administration Instructions

KORSUVA is removed by the dialyzer membrane and must be administered after blood is no longer circulating through the dialyzer.
Administer KORSUVA by intravenous bolus injection into the venous line of the dialysis circuit at the end of each HD session.
The dose may be given either during or after rinse back of the dialysis circuit.
If the dose is given after rinse back, administer KORSUVA into the venous line followed by at least 10 mL of normal saline flush.
If the dose is given during rinse back, no additional normal saline is needed to flush the line.
The dose must be administered within 60 minutes of the completion of the syringe preparation. Discard any unused product.
