Opioids and benzodiazepines together

An opioid and a benzodiazepine should not be prescribed together unless there is a clear, discussed reason - the combination raises overdose risk.

14% of the time this step is missed
0% missed at the best-performing clinics
3.7x higher risk of harm when missed
Safety first: Do not stop either medicine abruptly on your own - ask your prescriber to review the combination safely.

The silent should: An opioid and a benzodiazepine should not be prescribed together unless there is a clear, discussed reason — the combination raises overdose risk.

In our analysis of de-identified U.S. psychiatric records, this step was missing 14% of the time it should have happened.

It is fixable: the best-performing clinics miss it only 0% of the time — a 14-point gap that is about the system, not the patient.

Questions for your doctor the next time you see them

Copy a line and ask it — these are questions, never instructions to change treatment.

  • I'm prescribed both an opioid and a benzodiazepine - is that combination safe for me?
  • Can we review whether I still need both, and can I have naloxone on hand?

The evidence

In our analysis, taking a benzodiazepine and an opioid together was linked to a 3.7x higher rate of overdose compared with an opioid alone.
