Ferumoxytol
Dosing in kidney impairment
Evaluate the hematologic response (hemoglobin, ferritin, iron and transferrin saturation) at least one month following the second ferumoxytol infusion. The recommended ferumoxytol injection dose may be readministered to patients with persistent or recurrent iron deficiency anemia. For patients receiving hemodialysis, administer ferumoxytol once the blood pressure is stable and the patient has completed at least one hour of hemodialysis.
Preparation and administration
2 DOSAGE AND ADMINISTRATION The recommended dose of ferumoxytol injection is an initial 510 mg dose followed by a second 510 mg dose 3 to 8 days later. Administer ferumoxytol as an intravenous infusion in 50 to 200 mL 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP over at least 15 minutes. Take measures to avoid extravasation, as this can lead to skin discoloration or staining, which may be long lasting.
If extravasation occurs, discontinue Ferumoxytol administration at that site. Administer while the patient is in a reclined or semi-reclined position. Ferumoxytol injection does not contain antimicrobial preservatives. Discard unused portion. Ferumoxytol injection, when added to intravenous infusion bags containing either 0.9% Sodium Chloride Injection, USP (normal saline), or 5% Dextrose Injection, USP, at concentrations of 2 to 8 mg elemental iron per mL, should be used immediately but may be stored at controlled room temperature (25°C ± 2°C) for up to 4 hours or refrigerated (2 to 8° C) for up to 48 hours The dosage is expressed in terms of mg of elemental iron, with each mL of ferumoxytol containing 30 mg of elemental iron.
Monitor for signs and symptoms of hypotension following each ferumoxytol infusion. Allow at least 30 minutes between administration of ferumoxytol and administration of other medications that could potentially cause serious hypersensitivity reactions and/or hypotension, such as chemotherapeutic agents or monoclonal antibodies.
Administer ferumoxytol as an intravenous infusion in 50 to 200 mL 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP over at least 15 minutes.
