Summary
Procainamide is a class Ia antiarrhythmic that prolongs the QT interval and can cause torsades de pointes. Goserelin may add to the effect, raising the risk of ventricular arrhythmia.
What this interaction means in plain words
Goserelin and Procainamide 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 QT prolongation from androgen deprivation (goserelin) and sodium and potassium channel blockade (procainamide).
What to do
Obtain a baseline ECG and monitor the QTc along with procainamide levels. Consider an alternative antiarrhythmic if the QTc becomes prolonged.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
