How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
Buprenorphine and dezocine can work against each other. Both attach to the same pain receptors in your body, but they do it in different ways. When taken together, dezocine can actually bump buprenorphine off those receptors. This can make your pain relief weaker and, if you rely on buprenorphine, it can trigger sudden withdrawal symptoms like sweating, chills, stomach cramps, or feeling very anxious.
On top of that, both are opioids, so combining them can add up to cause heavy drowsiness and slowed breathing, which can be dangerous. The good news is your care team can manage this safely. Please talk with your doctor or pharmacist before using both so they can guide you.
Direction: Dezocine is a mixed opioid agonist/antagonist; buprenorphine is a high-affinity partial mu agonist. Co-use produces competitive receptor interaction that may reduce buprenorphine analgesia and precipitate withdrawal. Neither is a prodrug requiring activation.
- Additive risk: combined opioid/CNS depressant effect raises risk of respiratory depression, profound sedation, and (per file) serotonin syndrome.
- Severity/evidence: major; theoretical.
- Onset: unspecified.
Management: Avoid concomitant use; cessation of the other CNS depressant is preferred. If unavoidable, use lowest effective dose, monitor for sedation, respiratory depression, and serotonin syndrome, consider higher level of care, and strongly consider prescribing naloxone.
What happens
Reduced analgesic effect or precipitation of withdrawal symptoms, and an increased risk of serotonin syndrome and respiratory depression
Interaction Deep Dive
Do not combine buprenorphine with a partial agonist opioid analgesic or a mixed opioid agonist/antagonist, since doing so can diminish buprenorphine's analgesic action and trigger withdrawal symptoms. Furthermore, giving buprenorphine together with a CNS depressant can produce additive CNS depression along with a heightened risk of serotonin syndrome, respiratory depression, profound sedation, coma, and death. Discontinuing the other CNS depressants is preferable to using them together. Monitoring in a higher level of care or a taper may be suitable in certain situations. In other cases, it may be appropriate to gradually wean a patient off a prescribed benzodiazepine or another CNS depressant, or to reduce it to the lowest effective dose. When concurrent use cannot be avoided, watch for sedation, respiratory depression, and the signs and symptoms of serotonin syndrome; consider alternative treatments for insomnia or anxiety, and give strong consideration to prescribing naloxone for the emergency treatment of opioid overdose1.
Why it happens (mechanism)
Opioid receptor antagonism; additive serotonergic effects and respiratory depression
How to manage this interaction
Keep taking your medications as prescribed and do not stop or change either one on your own. Bring this combination to your prescriber or pharmacist so they can plan the safest approach.
- Your team will usually try to avoid using both together, since stopping one is preferred over combining them.
- If both are truly needed, the dose may be adjusted and individualized, and your team may monitor you more closely, sometimes in a higher level of care.
- Watch for heavy drowsiness, slowed or shallow breathing, confusion, or withdrawal symptoms.
- Ask whether naloxone (overdose rescue) is right to have on hand.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Dezocine and Buprenorphine together?
Buprenorphine and dezocine can cancel out pain relief, trigger withdrawal, and add up to dangerous sedation and slowed breathing, so this combination is usually avoided. Talk with your doctor or pharmacist before using both together. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Dezocine and Buprenorphine interaction?
It is rated major. Potentially serious — often needs a change or close monitoring.
How quickly could this interaction happen?
The documented onset is "unspecified". The timing of this interaction is not well characterized.
