• Quinine (a medicine for malaria), because it increases flecainide blood levels.
• Ritonavir, lopinavir, and indinavir (medicines for AIDS treatment), because they increase flecainide blood levels.
• Diuretics, because they may alter potassium blood levels and increase flecainide toxicity.
• Cimetidine (an anti-acid), because it increases flecainide blood levels.
• Bupropion (a medicine to help quit smoking), because it increases flecainide blood levels.
• Terbinafine (a medicine for fungi), may increase flecainide blood levels.
