Flecainide Acetate Phenytoin
ModerateThe leaflet text for flecainide acetate cuts off before it reaches phenytoin, so it gives no information on how flecainide and phenytoin affect each other. The only general advice here is to tell your doctor or pharmacist about every medicine you take, including ones bought without a prescription, so they can check whether the two are safe together.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
