Adult Dosing

Pediatric Dosing[1]

  • Start infusion at 0.05 mcg/kg/min IV
    • Titrate to 0.1 mcg/kg/min as tolerated, monitoring for hypotension (and apnea)

Adverse Reactions

  • Beware of three common side effects that may require further resuscitation[2][3]:
    • Apnea (12%), which requires respiratory monitoring with ETCO2 capnography, potential mechanical ventilation, and/or ALS/PALS transport if needing transfer to higher level of care
    • Peripheral flushing with or without hypotension (10%), which requires fluid resuscitation
    • Fever (14%)
  • Others:


  • Half-life: 5-10m
