Effect on pacemakers and ICDs
Amiodarone
- Increases the effect of digoxin and warfarin
At high doses, may increase energy requirements on ICDs Disopyramide
- More potential for side effects when given with phenobarbital, phenytoin, or rifampin
Flecainide
- Increases the effect of digoxin
Ibutilide
- Prolongs the heart's QT interval
Unknown Lidocaine
- More potential for side effects when given with propranolol, metoprolol, or cimetidine
Mexiletine
- Increases the effect of theophylline
- Less effective when given with phenobarbital, phenytoin, or rifampin
Not predictable Procainamide
- More potential for side effects when given with cimetidine, alcohol, or amiodarone
Propafenone
- Increases the effect of digoxin, theophylline, and warfarin
- Less effective when given with phenobarbital, phenytoin, or rifampin
- More potential for side effects when given with cimetidine
Quinidine
- Increases the effect of digoxin and warfarin
- More potential for side effects when given with heparin, verapamil, or cimetidine
- Less effective when given with phenobarbital, phenytoin, or rifampin
