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 affect your heart's rhythm. Nilotinib (a cancer medicine) and sertraline (used for depression and anxiety) can each slightly stretch out a part of your heartbeat called the QT interval. When you take them together, that effect can add up, which in rare cases could lead to an abnormal heartbeat.
This is a caution based on how the drugs work, not on a lot of real-world reports. Please don't stop either medicine on your own. Let your doctor or pharmacist know you take both. They can check your heart with a simple EKG and watch your body's mineral levels so this stays safe and well managed.
Interaction: Additive QT interval prolongation from concurrent nilotinib and sertraline, raising the theoretical risk of ventricular arrhythmias including torsades de pointes.
- Mechanism: Pharmacodynamic additivity; both agents independently prolong the QT interval. Neither is a prodrug relevant here.
- Direction: Increased combined QT effect.
- Evidence: Theoretical; severity rated major. Onset unspecified.
- Management: Manufacturer labeling advises avoiding coadministration. If unavoidable, obtain baseline and follow-up ECGs, correct and monitor K+ and Mg2+, and review other QT-prolonging agents. Nilotinib carries a boxed warning for QT prolongation, warranting particular caution.
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
Because concurrent use raises the potential for QT prolongation and/or ventricular arrhythmias, sertraline should not be given together with this drug1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
The main strategy here is caution and monitoring. Drug labeling suggests avoiding this combination when possible, so your care team may consider whether an alternative to one of the medicines is appropriate. If you need both, they can manage it safely.
- Keep taking both medicines exactly as prescribed unless your prescriber tells you otherwise.
- Your team may order an EKG to check your heart rhythm and may check blood minerals like potassium and magnesium.
- Tell your pharmacist about any other medicines you take, since some also affect heart rhythm.
- Report fainting, dizziness, or a racing or pounding heartbeat right away.
Management is individual — confirm any change with your pharmacist or prescriber.

Always confirm with your pharmacist or prescriber before making any change.
