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 sulpiride (used for certain mental health conditions) can each affect the timing of your heartbeat. Doctors call this QT prolongation. When two medicines that do this are taken together, the effect can add up, which in rare cases can lead to an irregular heartbeat.
The good news is this is a possible risk, not something that happens to everyone. Please don't stop either medicine on your own. Talk with your pharmacist or doctor, who can check your heart rhythm and make sure this combination is safe for you or choose a better option.
Mechanism: Additive QT-interval prolongation from concurrent use of two agents with independent QT-prolonging potential (sertraline and sulpiride). No prodrug activation involved; effect is pharmacodynamic (additive), not PK-mediated.
Direction/effect: Increased risk of QT prolongation and torsades/ventricular arrhythmias.
- Severity: Major; evidence: theoretical.
- Onset: Unspecified.
- Management: Documented recommendation is to avoid coadministration. If unavoidable, consider ECG monitoring, correct electrolytes (K+, Mg2+), review other QT-prolonging agents, and individualize therapy per the care team.
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
Do not use sertraline together with this drug, since combining them can raise the likelihood of QT prolongation and/or ventricular arrhythmias1.
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 the QT-prolonging effects can add up.
- Keep taking both as prescribed until you have spoken with your prescriber or pharmacist. Do not stop or change either one on your own.
- Your care team may monitor you more closely, including checking your heart rhythm (ECG) and blood electrolytes, or may choose an alternative medicine.
- Tell your team about any other medicines that affect the heart.
- Seek prompt care for fainting, palpitations, dizziness, or an irregular heartbeat.
Management is individual — confirm any change with your pharmacist or prescriber.
