Does Buprenorphine Interact with Alprazolam?

Buprenorphine and Alprazolam have a major drug interaction according to U.S. FDA drug labeling data. Concomitant use increases risk of respiratory depression due to actions at different CNS receptor sites. The mechanism involves benzodiazepines interact at gaba(a) sites; opioids at mu receptors, causing additive respiratory depression. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.

How This Interaction Works

The interaction between Buprenorphine and Alprazolam occurs because benzodiazepines interact at gaba(a) sites; opioids at mu receptors, causing additive respiratory depression. Clinically, this means concomitant use increases risk of respiratory depression due to actions at different cns receptor sites. This is classified as a major interaction, meaning it could cause serious harm if not properly managed. Your healthcare provider may need to adjust dosages, substitute one medication, or increase monitoring frequency.

What To Tell Your Doctor or Pharmacist

If you are taking Buprenorphine and your doctor is considering prescribing Alprazolam (or vice versa), make sure to:

  • Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
  • Ask whether the benefits of combining these medications outweigh the risks for your specific situation
  • Ask what symptoms to watch for that would indicate the interaction is causing problems
  • Ask how frequently you should be monitored while these are co-prescribed
  • Ask whether any dosage adjustments are needed
  • Never stop or change either medication without first consulting your healthcare provider
