- flecainide
Interactions between your drugs
flecainide boceprevir
Applies to: flecainide and boceprevir
MONITOR: Coadministration with the hepatitis C virus (HCV) NS3/4A protease inhibitors, boceprevir and telaprevir, may increase the plasma concentrations of certain antiarrhythmic agents including flecainide, lidocaine, and propafenone. The mechanism of interaction has not been described. The interaction has not been specifically studied, but could conceivably lead to serious and/or life-threatening reactions including cardiac arrhythmias and other toxicities if levels are significantly increased.
MANAGEMENT: Caution is advised if boceprevir or telaprevir must be used with flecainide, lidocaine, or propafenone. Pharmacologic response and plasma antiarrhythmic drug levels should be monitored more closely whenever the HCV NS3/4A protease inhibitor is added to or withdrawn from therapy, and the antiarrhythmic dosage adjusted as necessary.

Drug and food interactions
boceprevir food
Applies to: boceprevir
ADJUST DOSING INTERVAL: Food significantly enhances the oral bioavailability of boceprevir. When given at 800 mg three times daily with food, boceprevir exposure increased by up to 65% relative to administration in the fasting state. The bioavailability of boceprevir was similar regardless of meal type (e.g., high-fat versus low-fat) or whether taken 5 minutes prior to eating, during a meal, or immediately following completion of the meal. Therefore, boceprevir may be taken without regard to either meal type or timing of the meal.
MANAGEMENT: To ensure maximal oral absorption, boceprevir should be administered with a meal or light snack.
