What this interaction means in plain words
Anagrelide and Buprenorphine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

What to do
Obtain a baseline ECG and correct potassium and magnesium before starting, then monitor the QTc during therapy. Prefer an alternative analgesic when the patient has other QT risk factors.
