Rationale
Naltrexone stocking is recommended in facilities that would normally manage people who require naloxone infusions. In the uncommon scenario where patients are opioid naïve, naltrexone can be used as an alternative to a naloxone infusion.
Precaution
Naltrexone should not be given to opioid-dependent patients as it will reliably cause acute opioid withdrawal.
