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.
Desflurane is a gas used to keep you asleep during surgery, and sertraline (a common antidepressant) is a pill you may take every day. Each of these can, on its own, slightly affect the heart's electrical timing (called the QT interval). When used together, that effect can add up, which in rare cases could lead to an irregular heartbeat.
The good news is this concern is mostly theoretical, and your anesthesia team keeps a close eye on your heart rhythm during surgery. Be sure your surgeon and anesthesiologist know you take sertraline so they can plan and watch for this. Please don't stop any medication on your own.
Effect: Additive risk of QT-interval prolongation and, rarely, torsade de pointes when volatile anesthetic desflurane is given to a patient on sertraline.
Mechanism: Pharmacodynamic additive QT prolongation. Not a metabolic/prodrug interaction; direction is additive PD effect, not altered exposure.
- Direction: Increased combined QT effect
- Evidence: Theoretical
- Severity: Major
- Onset: Unspecified (intraoperative relevance)
Management: Continuous ECG/cardiac rhythm monitoring perioperatively. Assess additional risk factors (electrolyte abnormalities, bradycardia, other QT agents, hepatic impairment). Correct hypokalemia/hypomagnesemia. Individualize based on patient susceptibility.
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
When desflurane is given alongside additional agents that prolong the QT interval, the combined effect may heighten the likelihood of additive QT prolongation as well as torsade de pointes. In patients who are susceptible, cardiac rhythm should be monitored closely during desflurane administration1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
This interaction is managed by your surgical and anesthesia team, not something you fix at home.
- Keep taking sertraline as prescribed unless your doctor specifically tells you otherwise before surgery.
- Tell your surgeon, anesthesiologist, and pharmacist that you take sertraline, plus any other medicines and supplements.
- Your team may monitor your heart rhythm (ECG) closely during and after anesthesia and check your electrolytes (like potassium and magnesium).
- Mention any history of heart rhythm problems, fainting, or family history of sudden cardiac events.
Your care team can tailor monitoring and choices to keep you safe.
Management is individual — confirm any change with your pharmacist or prescriber.

Common questions
Can I take Sertraline and Desflurane together?
Combining desflurane during surgery with sertraline may add up to a small, mostly theoretical risk of QT prolongation, so make sure your anesthesia team knows you take sertraline and let them monitor your heart rhythm. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Sertraline and Desflurane 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.
