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 pasireotide (Signifor) can slightly affect the timing of your heartbeat, a change doctors call QT prolongation. When you take them together, that effect can add up, which in rare cases could lead to an irregular heartbeat.
This concern is based mostly on how these drugs work in theory, not on a lot of real-world cases, so please don't worry. The good news is your care team can manage this easily by watching your heart rhythm and adjusting your treatment if needed. Keep taking both exactly as prescribed, and check with your doctor or pharmacist before making any changes.
Interaction: Additive QT interval prolongation with combined sertraline and pasireotide, raising theoretical risk of ventricular arrhythmias (including torsades de pointes).
Mechanism: Pharmacodynamic (additive), not metabolic. Both agents independently prolong the QT interval; neither is a prodrug and the direction is additive PD risk, not altered PK.
- Severity: Major
- Evidence: Theoretical
- Onset: Unspecified
Management: Manufacturer guidance advises avoiding coadministration where possible. If combined, obtain baseline and follow-up ECGs, monitor and correct electrolytes (K+, Mg2+), and review other QT-prolonging agents. Dose should be individualized by the care team.
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
Concurrent use of this drug with sertraline should not occur, since doing so can heighten the likelihood of QT prolongation and/or ventricular arrhythmias1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
Your care team can manage this concern safely. Because both medicines can nudge your heart rhythm, here is what typically happens:
- Your team may prefer to avoid using them together when a suitable alternative exists.
- If both are needed, they may monitor you more closely, including checking your heart rhythm (ECG) and blood minerals like potassium and magnesium.
- Any dose may need to be adjusted and individualized by your prescriber.
What you should do: Keep taking both as prescribed unless told otherwise. Tell your pharmacist or doctor about any fainting, dizziness, or a fast or irregular heartbeat, and mention all other medicines you take.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Sertraline and Pasireotide together?
Sertraline and pasireotide can each prolong the QT interval, so combining them may add up and raise the risk of an irregular heartbeat; your care team will usually avoid the combination or monitor your heart rhythm closely. Do not change either medicine on your own. Always confirm with your pharmacist or prescriber before making any change.
