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.
Both of these medicines can raise serotonin, a chemical messenger in your brain. Opipramol and sertraline each affect serotonin, so taking them together can add up and, in rare cases, push levels too high. This is called serotonin syndrome.
Warning signs to watch for include feeling agitated or restless, a fast heartbeat, sweating, shivering, muscle twitching or stiffness, and shaking. These are most likely when you first start or when a dose goes up. The good news is that your care team can manage this by watching you closely and adjusting things if needed. Keep taking both as prescribed, and call your pharmacist or doctor right away if you notice these symptoms.
Mechanism: additive serotonergic effects. Both agents enhance serotonergic tone (sertraline via SERT inhibition; opipramol has serotonergic activity), so combined use raises the theoretical risk of serotonin syndrome. Neither is a prodrug here; this is a pharmacodynamic, not pharmacokinetic, interaction.
- Direction: increased serotonergic effect.
- Severity: major; evidence: theoretical.
- Onset: unspecified; highest risk at initiation and dose escalation.
- Monitor: agitation, hyperthermia, tachycardia, diaphoresis, clonus, hyperreflexia, rigidity, mental status changes.
Management: monitor closely, especially during titration. If serotonin syndrome is suspected, discontinue serotonergic agents immediately and begin supportive care.
What happens
An increased risk of serotonin syndrome
Interaction Deep Dive
When sertraline is taken together with this medication, the likelihood of serotonin syndrome may be elevated. Patients should be watched carefully for signs of serotonin syndrome, particularly when therapy is being 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
This combination can usually be managed with close monitoring. Your care team may watch you more carefully, particularly when either drug is started or a dose is raised.
- Keep taking both medicines exactly as prescribed unless your prescriber tells you otherwise.
- Know the warning signs: agitation, confusion, fast heartbeat, high temperature, heavy sweating, shivering, muscle twitching, or stiffness.
- Seek medical help promptly if these symptoms appear, since serotonin syndrome may need the medicines stopped and supportive treatment.
- Ask your pharmacist or doctor before adding any new serotonergic medicine or supplement.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Sertraline and Opipramol together?
