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.
You've been prescribed sertraline (an antidepressant) and vilanterol (an inhaled medicine that opens the airways). Both of these can, on their own, slightly affect the heart's electrical rhythm, causing something called QT prolongation. When two medicines that do this are taken together, that effect can add up and, in rare cases, lead to an irregular heartbeat.
The good news is that this concern is mostly theoretical, meaning it's based on how the drugs work rather than lots of real-world problems. Please don't stop either medicine on your own. Talk with your pharmacist or doctor so they can review your heart health and decide the safest plan for you.
Effect: Additive QT interval prolongation with increased risk of ventricular arrhythmias (e.g., torsades de pointes) when sertraline is combined with vilanterol.
Mechanism: Pharmacodynamic (additive), not a metabolic interaction. Both agents carry independent potential to prolong the QTc; vilanterol, a long-acting beta-2 agonist, can also contribute via beta-agonist effects (tachycardia, hypokalemia).
- Direction/magnitude: Additive PD effect; magnitude not quantified.
- Onset: Unspecified.
- Evidence: Theoretical.
- Management: Avoid coadministration where possible. If combined, assess baseline QTc, electrolytes (K+, Mg2+), and other QT-prolonging agents; monitor ECG. Individualize per patient risk factors.
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
The combined use of sertraline with this medication should be avoided, since doing so can raise the likelihood of QT prolongation and/or ventricular arrhythmias1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
What your care team may do:
- Where possible, they may avoid using these two together, or select an alternative for one of them.
- If both are needed, they may monitor you more closely, which can include checking your heart rhythm (ECG) and blood levels of potassium and magnesium.
- They will weigh your personal heart risk factors before deciding the best approach for you.
What you can do: Keep taking both exactly as prescribed for now. Tell your pharmacist or prescriber about any dizziness, fainting, or a racing or irregular heartbeat, and mention any other medicines you take.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Sertraline and Vilanterol together?
Sertraline and vilanterol can each affect heart rhythm, so together they may add up and raise the risk of QT prolongation; this is a theoretical concern, so ask your pharmacist or doctor to review the combination rather than changing anything yourself. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Sertraline and Vilanterol interaction?
