What are the possible side effects of INFeD? In doses 500 mg, iron dextran plasma concentrations decrease exponentially with a half-life of about 6 hours. Risk of developing potentially life-threatening anaphylactic reactions. Use the following formula to calculate required total iron dextran dosage in mL: 0.02 blood loss (in mL) hematocrit (expressed as a decimal fraction) = total dosage of iron dextran injection (mL). INFeD should be injected only into the muscle mass of the upper outer quadrant of the buttock - never into the arm or other exposed areas - and should be injected deeply, with a 2-inch or 3-inch 19 or 20 gauge needle. 0000026943 00000 n Off-label: Use is not currently included in the labeling approved by the US Food and Drug Administration.
