Estimated Resupply Dates

    • Pfizer has all nalbuphine presentations available.

Alternative Agents & Management

    • Low-dose naloxone continuous IV infusion is commonly used for treatment or prevention of opioid-induced pruritus and is the most evidence-based alternative to nalbuphine.[2-5] The majority of published data support a naloxone dose of 0.25 mcg/kg/h to 1 mcg/kg/h administered as a continuous IV infusion for children and adults receiving IV opioids.[6-9] Naloxone doses greater than 1 mcg/kg/h may require additional analgesia or result in decreased pain relief.[8-9] Monitor patients for signs of decreased pain control.
