Buprenorphine buccal and Escitalopram 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

What to do
Obtain a baseline ECG and correct electrolyte abnormalities; monitor the QTc and for serotonin toxicity symptoms, and avoid exceeding the recommended escitalopram dose.
