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 buprenorphine (a pain and addiction medicine) and goserelin (a hormone therapy) can each affect your heart's electrical rhythm in a way doctors call 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.
Right now this is more of a theoretical concern. The good news is that your care team can manage it, often by checking your heart rhythm and your potassium and magnesium levels. Please don't stop either medicine on your own. Just talk with your pharmacist or doctor so they can keep an eye on things.
Effect: Additive QT interval prolongation when buprenorphine is combined with goserelin.
Mechanism: Both agents are independently associated with QT prolongation; the combination is additive on cardiac repolarization. Neither is a prodrug, so no activation-flip applies.
Evidence: Theoretical; combined risk not quantified. Onset: unspecified. Severity: major.
- Assess baseline and periodic ECG in at-risk patients
- Correct electrolytes (K+, Mg2+); watch for bradycardia, CHF, baseline/congenital long-QT, digitalis therapy
- Consider a non-QT-prolonging alternative where feasible; individualize monitoring
What happens
An increased risk of QT interval prolongation
Interaction Deep Dive
Do not administer buprenorphine together with agents capable of extending the QT interval342. It remains unknown what risk arises when buprenorphine is paired with other QT prolonging drugs. When prescribing buprenorphine to patients presenting risk factors, including hypokalemia, bradycardia, recent conversion from atrial fibrillation, congestive heart failure, digitalis therapy, baseline QT prolongation, subclinical long-QT syndrome, or severe hypomagnesemia, these considerations should factor into clinical decision making 1.
Why it happens (mechanism)
Additive QT interval prolongation
How to manage this interaction
Both drugs can nudge your heart rhythm in the same direction, so your care team pays extra attention when they are used together.
- Keep taking both as prescribed unless your doctor tells you otherwise.
- Your team may monitor you more closely, which can include heart-rhythm (ECG) checks and blood tests for potassium and magnesium.
- In some cases they may choose an alternative medicine, and any dosing decisions will be individualized by your care team.
- Tell your prescriber if you have heart failure, a slow heartbeat, a known long-QT history, or take a digitalis (digoxin) heart medicine.
Report fainting, dizziness, or a fluttering/pounding heartbeat right away.
Management is individual — confirm any change with your pharmacist or prescriber.
Common questions
Can I take Goserelin and Buprenorphine together?
Buprenorphine and goserelin can each prolong the QT interval, so together the effect may add up; keep taking both as prescribed and ask your care team about heart-rhythm and electrolyte monitoring, especially if you have heart risk factors. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Goserelin and Buprenorphine interaction?
It is rated major. Potentially serious — often needs a change or close monitoring.
How quickly could this interaction happen?
The documented onset is "unspecified". The timing of this interaction is not well characterized.
