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 sertraline (an antidepressant) and sultopride (an antipsychotic) can each affect the timing of your heartbeat. Doctors call this QT prolongation, which just means one part of your heart's electrical cycle takes a little longer to reset. When you take two medicines that both do this, the effect can add up and, rarely, lead to an irregular heartbeat.
This concern is based on how these drugs work rather than lots of real-world reports, but because a heart rhythm problem is serious, it is worth taking seriously. The good news is your care team can manage this easily, often by choosing a different medicine or keeping a closer eye on your heart. Please talk with your doctor or pharmacist before making any changes.
Effect: Additive QT interval prolongation with increased risk of ventricular arrhythmias (including torsades de pointes) when sertraline is combined with sultopride.
Mechanism: Pharmacodynamic, not PK. Both agents independently prolong cardiac repolarization; the effect is additive. Neither is a prodrug relevant here, so this is a PD interaction, not a metabolic one.
- Direction: Increased QT-prolonging effect.
- Evidence: Theoretical.
- Severity: Major.
- Management: Avoid coadministration where possible. If unavoidable, obtain baseline and follow-up ECGs, correct electrolytes (K+, Mg2+), and monitor for symptoms. Dosing should be individualized by the care team.
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
Because it can raise the likelihood of QT prolongation and/or ventricular arrhythmias, using sertraline together with this drug should be avoided1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
The documented advice is to avoid using these two together when possible, because both can prolong the QT interval and the effect adds up.
- Keep taking both medicines as prescribed until you have spoken with your prescriber or pharmacist. Do not stop either one on your own.
- Your care team may choose an alternative medicine for one of them, or if both are truly needed, they may monitor you more closely (such as with heart tracings and blood tests) and individualize your dosing.
- Tell your doctor right away about fainting, palpitations, dizziness, or an irregular heartbeat.
Management is individual — confirm any change with your pharmacist or prescriber.
