Summary
Both agents have been linked to QT prolongation, so together they may add to arrhythmia risk. Buprenorphine's effect is modest and dose-related, but it matters in patients with other risk factors.
What this interaction means in plain words
Buprenorphine buccal and Lithium can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive pharmacodynamic effects on cardiac repolarization.
What to do
Check a baseline ECG in patients with cardiac risk factors and monitor the QTc after dose changes. Correct electrolyte abnormalities and monitor serum lithium levels.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
