Buprenorphine
Olodaterol
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 your medicines can affect the timing of your heartbeat. Buprenorphine (a pain or addiction medicine) and olodaterol (Striverdi, an inhaler for breathing) can each stretch out a part of the heart's electrical cycle called the QT interval. When two medicines do this together, the effect can add up and, in rare cases, lead to an abnormal heart rhythm.
This concern is theoretical, meaning it is based on how these drugs work rather than on many reported cases. Please don't stop either one on your own. Let your doctor or pharmacist know you take both so they can keep an eye on things and manage it safely.
Effect: Additive QTc prolongation and increased risk of ventricular arrhythmias (including torsades de pointes) with concurrent buprenorphine and olodaterol.
Mechanism: Pharmacodynamic (additive) QT prolongation. Beta-agonists such as olodaterol produce ECG changes (T-wave flattening, QTc prolongation, ST depression); buprenorphine has dose-dependent QT effects. Neither is a prodrug relevant here.
- Direction/magnitude: Additive; magnitude not quantified.
- Onset: Unspecified.
- Evidence: Theoretical.
- Management: Use extreme caution. Consider baseline and follow-up ECG, correct electrolytes (K+, Mg2+), review other QT-prolonging agents, and monitor for palpitations/syncope.
What happens
An increased risk of QT interval prolongation and an increased risk of ventricular arrhythmias
Interaction Deep Dive
ECG abnormalities including T wave flattening, QTc interval prolongation, and ST segment depression have been documented with beta-agonists. Because coadministration of olodaterol (a long acting beta-adrenergic agonist) with QT-prolonging drugs may lead to QT interval prolongation and heighten the likelihood of ventricular arrhythmias, use extreme caution in this situation1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
Your care team can manage this safely. Keep taking both medicines exactly as prescribed unless your doctor tells you otherwise.
- Tell your pharmacist and prescriber that you take buprenorphine and olodaterol together.
- Your team may check an ECG and your electrolyte levels, and may monitor you more closely.
- Mention any other medicines that affect heart rhythm.
- Get medical help right away if you feel fainting, dizziness, a racing or irregular heartbeat, or palpitations.
Management is individual — confirm any change with your pharmacist or prescriber.
