Administration advice:
- For IV infusion only
- Pretreatment is recommended 30 to 60 minutes prior to start of infusion and may include antihistamines with or without antipyretics.
- Prepare using low protein binding containers and administer diluted solution using a low protein binding infusion set with an in-line, low-protein-binding 0.2 micrometer filter; do not administer with other products in infusion tubing.
- Dilute to a final volume of 250 mL and infuse total volume over no less than 4 hours by controlled IV infusion using an infusion pump; initial infusion rate is 6 mL/hr for the first hour; if well tolerated, may increase to 80 mL/hr for the remaining 3 hours; extend infusion time up to 20 hours if infusion reaction occurs.
- For patients weighing 20 kg or less, or those susceptible to fluid overload, consider diluting in a volume of 100 mL and decreasing infusion rate so that the total infusion duration remains no less than 4 hours.
