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.
Papaveretum is a strong opioid painkiller (a mix of opium-based medicines), and sertraline is an antidepressant. When taken together, they can both raise serotonin levels in your body. In rare cases this can lead to a problem called serotonin syndrome.
Warning signs include feeling agitated or confused, a fast heartbeat, sweating, shaking, muscle twitching, or a high fever. This is more likely when you first start one of these medicines or after a dose goes up. The good news is your care team knows about this and can watch for it. If you notice these symptoms, contact your doctor or pharmacist right away, and don't stop either medicine on your own.
Interaction: Additive serotonergic effects from concurrent papaveretum (opioid; some opioids have serotonergic activity) and sertraline (SSRI) may increase the risk of serotonin syndrome.
- Direction/mechanism: Pharmacodynamic, additive serotonergic burden (not a PK enzyme interaction). Neither drug is a prodrug relevant here.
- Evidence: Theoretical; severity rated major.
- Onset: Unspecified; risk highest at initiation and dose escalation.
- Monitoring: Watch for agitation, autonomic instability, hyperthermia, clonus, hyperreflexia, tremor.
- Management: If serotonin syndrome is suspected, discontinue serotonergic agents and begin supportive care.
What happens
An increased risk of serotonin syndrome
Interaction Deep Dive
Taking sertraline together with this drug can raise the likelihood of serotonin syndrome. Patients should be watched carefully for signs of serotonin syndrome, particularly when therapy is started and when doses are raised. If serotonin syndrome is suspected, stop sertraline and any other serotonergic agents being used at once, and begin supportive care1.
Why it happens (mechanism)
Additive serotonergic effects
How to manage this interaction
Both medicines can be used together when needed, but your care team will keep an eye out for a rare reaction called serotonin syndrome, especially when starting either drug or raising a dose.
- Keep taking both as prescribed unless your doctor tells you otherwise.
- Watch for warning signs: agitation, confusion, fast heartbeat, heavy sweating, shivering, muscle twitching or stiffness, or fever.
- Act fast if symptoms appear: seek medical help promptly. Your team may stop the serotonergic medicines and give supportive treatment.
- Ask your pharmacist or prescriber before adding any new medicines, since other serotonergic drugs add to the risk.
Management is individual — confirm any change with your pharmacist or prescriber.
