Interactions between your drugs
procainamide bicalutamide
Applies to: procainamide and Casodex (bicalutamide)
GENERALLY AVOID: Class IA (e.g., disopyramide, quinidine, procainamide) and class III (e.g., amiodarone, dofetilide, sotalol) antiarrhythmic agents can cause dose-related prolongation of the QT interval. Theoretically, coadministration with other agents that can prolong the QT interval may result in additive effects and increased risk of ventricular arrhythmias including torsade de pointes and sudden death. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).
MANAGEMENT: Coadministration of class IA or class III antiarrhythmic agents with other drugs that can prolong the QT interval should preferably be avoided unless benefits are anticipated to outweigh the risks. Caution and clinical monitoring are recommended if concomitant use is required. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and food interactions
procainamide food
Applies to: procainamide
Ethanol may increase the acetylation of procainamide. Subtherapeutic plasma levels of procainamide may result in some patients. Because the acetylated metabolite of procainamide also possesses antiarrhythmic properties, the clinical effects are unclear.
