This is a critical safety issue for anyone on naltrexone: standard opioid pain medications won’t work normally while it’s active in your system — and in an emergency, this needs to be known immediately.

Why this matters: If you’re in a car accident, have emergency surgery, or experience another situation requiring urgent pain management, emergency medical staff need to know you’re on naltrexone right away — otherwise, standard opioid pain medications may be given at doses that don’t work as expected, sometimes leading to escalating doses in an attempt to achieve pain relief, which carries its own risks once the naltrexone blockade wears off or is overridden.

What to do about this in advance:

  • Wear a medical alert bracelet or carry a card stating you’re on naltrexone/Vivitrol — this is a genuinely important practical step, not an overcautious suggestion
  • Tell any new doctor, dentist, or surgeon about your naltrexone treatment before any planned procedure
  • Discuss a pain management plan in advance with your prescriber if you know a procedure is coming up, similar to the buprenorphine-and-surgery situation [link to that article for the parallel concept]

Non-opioid pain management options exist and work normally: Naltrexone doesn’t block non-opioid pain relief methods — regional anesthesia, non-opioid medications, and other approaches remain fully available and effective.

This is genuinely one of the more important practical safety details on this entire site for anyone on naltrexone — an emergency is not the time for this information to be discovered for the first time.
