Foods To Avoid When Taking Flecainide

Flecainide is a medication that treats paroxysmal supraventricular tachycardia and paroxysmal atrial fibrillation/flutter, which are potentially life-threatening irregular heartbeats. Certain foods can affect the metabolism of flecainide in the body. It is crucial to know the foods that can reduce the action of flecainide.


Saturated Fats

A diet high in saturated fats is linked to an increased risk of heart disease. Foods rich in saturated fats, such as red meats, full-fat dairy products, and certain oils, should be consumed in moderation. For individuals on the medication, it’s advisable to limit saturated fat intake to less than 10% of total daily calories.


Excessive sodium intake can exacerbate heart conditions by causing fluid retention and elevating blood pressure. Processed foods and convenience foods are often high in sodium and should be limited. Examples include deli meats, salty snacks, canned soups, and fast food items like pizza and salted fries.

Grapefruit And Caffeine

Grapefruit and grapefruit juice can affect the metabolism of flecainide, potentially leading to adverse effects. Similarly, excessive caffeine intake should be avoided, as it can interfere with the absorption and effectiveness of the medication.

Alcohol And Tobacco

Alcohol consumption and tobacco smoking can both diminish the effectiveness of flecainide. Drinking can alter the drug’s metabolism, while tobacco smoke contains substances that accelerate the removal of the medication from the body. It’s best to avoid or significantly reduce the intake of these substances while on flecainide therapy.


Does Flecainide Cause Bradycardia?

One of the questions that arise about flecainide is whether or not it causes bradycardia since it reduces the heart rate when it increases significantly. There is a chance that flecainide may cause new or worsen existing heart rhythm problems. In some rare cases, it has been reported to slow down the heart too much, leading to abnormally delayed heart rhythms.

Some medical literature suggests that flecainide is quite effective in treating certain types of arrhythmias, but it may also slow the heart rate too much in some patients. This side effect is not common but is a serious consideration when prescribing the medication. Patients experiencing symptoms such as difficulties breathing, chest pain, feeling hot, and feeling faint should seek medical attention, as these could be signs of bradycardia or other heart rhythm problems.
