What this interaction means in plain words
Bedaquiline and Triptorelin 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.

Why it happens
Additive pharmacodynamic QT prolongation.
What to do
Perform baseline ECG and repeat at least at 2, 4, 8 and 12 weeks and as needed; maintain normal potassium, calcium and magnesium. Stop bedaquiline or reconsider therapy if QTc becomes markedly prolonged or arrhythmia develops.
