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.
Anileridine is an opioid pain medicine, and sertraline is an antidepressant (an SSRI). Both can raise levels of a brain chemical called serotonin. When you take them together, that serotonin can build up too much and, in rare cases, cause a reaction called serotonin syndrome.
Warning signs can include feeling agitated or confused, a fast heartbeat, sweating, shaking, muscle twitching, or a high fever. This risk is greatest when you first start either drug or when a dose goes up. The good news is that your care team can manage this safely by watching you closely. Please don't stop either medicine on your own, but do call your doctor or pharmacist if these symptoms show up.
Mechanism: additive serotonergic effects. Sertraline (SSRI) increases synaptic serotonin; anileridine, an opioid, has serotonergic activity, so combined use raises the risk of serotonin syndrome. This is a pharmacodynamic interaction, not a metabolic one; neither drug's clearance is the driver.
Direction: additive/increased serotonergic effect. Severity: major. Evidence: theoretical. Onset: unspecified, highest during initiation and dose escalation.
- Monitor for clonus, hyperreflexia, agitation, autonomic instability, hyperthermia, and neuromuscular changes.
- Heighten vigilance at initiation and dose increases.
- If serotonin syndrome is suspected, discontinue sertraline and other serotonergic agents and begin supportive care.
What happens
An increased risk of serotonin syndrome
Interaction Deep Dive
Taking sertraline together with this drug may heighten the likelihood of serotonin syndrome. 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 along with any other serotonergic agents right away and begin supportive care1.
Why it happens (mechanism)
Additive serotonergic effects
How to manage this interaction
Both medicines can be used together when your care team decides it's appropriate, and they have clear ways to keep you safe.
- Keep taking both as prescribed unless your doctor tells you otherwise. Do not stop on your own.
- Your team may monitor you more closely, especially when you start either drug or when a dose is raised.
- Watch for warning signs: agitation, confusion, fast heartbeat, heavy sweating, shivering, muscle twitching or stiffness, or fever.
- Get help right away if these appear. If serotonin syndrome is suspected, your prescriber may stop the serotonergic medicines and start supportive treatment.
Ask your pharmacist or doctor if you have questions about combining these two.
Management is individual — confirm any change with your pharmacist or prescriber.
