Typical dosage for Nulibry

Nulibry (fosdenopterin) is given as an injection through the veins (IV). It's typically given through an infusion pump at a rate of 1.5 mL per minute. However, if the dose volume is below 2 mL, it's given as a slow IV push into your child's veins. The dose is calculated based on your child's actual body weight.

Children age less than 1 year: The typical dose is based on the gestational age of your baby:

  • Baby born premature (age less than 37 weeks): The typical starting dose is 0.4 mg/kg IV once per day. At month 1, the dose is raised to 0.7 mg/kg once per day. At month 3, the dose is raised to 0.9 mg/kg once per day.
  • Baby born full term (age 37 weeks and older): The typical starting dose is 0.55 mg/kg IV once per day. At month 1, the dose is raised to 0.75 mg/kg once per day. At month 3, the dose is raised to 0.9 mg/kg once per day.

Children age 1 year and older: The typical dose is 0.9 mg/kg IV once per day.
