Flecainide is a powerful medication that helps prevent and treat abnormal heartbeats, like atrial fibrillation or supraventricular tachycardia.
While it can help with these conditions, it’s important to watch what you eat while taking flecainide. Some foods may interact with the medicine and could cause problems or make it less effective.
This guide is designed to help you understand which foods can support your treatment and which may interfere with the effectiveness of the medication.
In simple terms, we’ll discuss what’s good to eat and what’s best to avoid while taking flecainide, ensuring that you can make informed choices for your well-being.
Flecainide is a medication used to treat irregular heartbeats. It belongs to a class of drugs called Class IC, which are known for their ability to stop abnormal heart rhythms without greatly affecting the heart rate.
It mainly works by blocking sodium channels, which in turn helps to normalize the heart’s electrical activity. According to the NIH, flecainide is a medication that works well for treating supraventricular arrhythmias, including atrial fibrillation.
Because flecainide can have strong effects and heart conditions are sensitive, doctors advise people who take this medication to have regular check-ups. It is also important for them to pay attention to any foods that may impact how the drug functions.
What is it used for?
Flecainide is known as an anti-arrhythmic drug. It does this by blocking specific electrical signals in the heart that can cause irregular rhythms. By managing irregular heartbeats, this medication can help lower the risk of blood clots and, in turn, decrease the chances of heart attack or strok
Flecainide is primarily used to manage a variety of arrhythmic conditions of the heart. It effectively treats ventricular and supraventricular tachycardias, including conditions like atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia (PSVT).
It is also used to prevent certain types of irregular heartbeat from coming back (like atrial fibrillation).
It works by stopping specific electrical signals in the heart that can cause the irregular rhythm. By treating irregular heartbeat, it can decrease the chance of blood clots, which then lowers the risk of having a heart attack or stroke.
However, due to its strength, it is important to take the medication only under the supervision of a medical professional.
Side Effects of Taking Flecainide
Flecainide helps control heart arrhythmias, but it can cause side effects. These can be common and not serious, or rare and more serious. Patients should be aware of this.
Common Side Effects
Common side effects of flecainide include:
- Dizziness or lightheadedness
- Visual disturbances, such as blurry vision
- Nausea
- Headache
- Fatigue or tiredness
- Palpitations, or a feeling that your heart is skipping a beat or beating too hard or too fast
These symptoms are usually mild and often resolve as the body adjusts to the medication. However, if they persist or worsen, it is important to consult your provider.
Serious Side Effects
More serious side effects are less common, but they require immediate medical attention. These include:
- Worsening of arrhythmias, a paradoxical effect known as proarrhythmia
- Shortness of breath or difficulty breathing
- Chest pain
- Fainting or severe dizziness
- Severe fatigue or weakness
- Swelling of the ankles or legs
Patients should be instructed to seek immediate medical help if they experience signs of a severe allergic reaction like rash, itching, swelling of the face, tongue, or throat, severe dizziness, or trouble breathing.
Foods to Avoid When Taking Flecainide
1. Foods High in Vitamin K
Flecainide helps with irregular heartbeats, but it’s important to watch what you eat to avoid any problems with the medication.
Vitamin K can have an impact on various heart medications, especially Flecainide. It’s important for blood clotting and heart health, which can be good in certain situations.
If you’re taking Flecainide and not having a consistent intake of vitamin K can impact its effectiveness and may cause issues with your treatment.
The American Heart Association suggests that it’s important for people on heart medication to maintain a diet with consistent Vitamin K intake. This helps in effectively managing their heart condition.
Eating too much or too little vitamin K can affect how medications work in the body, especially for people with heart rhythm problems. It’s a good idea to control the amount of foods with lots of vitamin K that you eat.
Here’s a list of Vitamin K-rich foods to avoid when taking Flecainide:
- Green leafy vegetables such as kale, spinach, turnip greens, collards, Swiss chard, and mustard greens
- Brussels sprouts
- Broccoli
- Asparagus
- Cabbage
- Parsley
- Lettuce
- Fish, liver, meat, eggs, and cereals (contain lower amounts of Vitamin K)
2. Foods high in Saturated Fats
Saturated fats, which are often found in animal products and processed foods, can build up plaque in the arteries.
According to MedlinePlus, your body needs healthy fats for energy and other bodily functions.
But if you take too much saturated fats (SAFA) then it may cholesterol buildup in your blood vessels. The SAFA raises your LDL (bad) cholesterol, which increases the risk of heart disease and stroke.
If you’re taking flecainide, it’s important to eat foods low in saturated fats. This helps reduce the chance of more heart problems.
To improve cardiovascular health, the American Heart Association recommends limiting saturated fat intake to 5-6% of total daily calories.
Here are some foods to avoid or limit to manage saturated fat intake:
- Red meats like beef and pork
- Full-fat dairy products such as butter, cream, cheese, and whole milk
- Processed meats such as sausages, hot dogs, and bacon
- Baked goods and fried foods that often contain palm oil, palm kernel oil, and coconut oil
- Snack foods like potato chips and crackers that may contain trans fats or hydrogenated oils
- Coconut oil which has a high concentration of saturated fats
3. Caffeinated Foods and Drinks
Caffeine is a natural stimulant that’s commonly found in tea, coffee, and cacao plants. It helps to wake up your brain and keep you alert. But if you’re taking Flecainide, caffeine can have stronger effects on you.
Experts suggest that patients with arrhythmias should generally reduce their caffeine consumption. This is because caffeine can cause palpitations and potentially worsen heart rhythm issues.
We don’t fully understand how caffeine and flecainide interact, but it’s believed that caffeine could make flecainide less effective in controlling irregular heart rhythms.
According to the Mayo Clinic, most healthy adults can safely consume up to 400 milligrams (mg) of caffeine per day. This is approximately the amount of caffeine found in four cups of brewed coffee, 10 cans of cola, or two “energy shot” drinks. Note that the caffeine content in beverages can vary significantly, particularly in energy drinks.
This means it would be smart to avoid or cut back on foods and drinks that are high in caffeine, like:
- Coffee (especially high-caffeine espresso drinks)
- Tea (particularly strong black and green tea)
- Energy drinks
- Soft drinks (soda, which often contains caffeine)
- Chocolate, especially dark chocolate or chocolate-based desserts
- Pre-workout supplements or energy bars that may contain added caffeine
To manage caffeine intake, it can be helpful to replace these caffeinated items with caffeine-free alternatives like herbal teas, water, and non-cola sodas. Don’t forget to check labels for hidden sources of caffeine, especially in medications or dietary supplements that you can buy without a prescription.
4. Excessively Salty Foods
Eating too much salt is bad for your heart. It can raise your blood pressure and cause problems for people with heart rhythm disorders.
If you take Flecainide, be careful about how much salt you eat. It’s important to have a healthy diet to manage your heart condition.
The American Heart Association advises that adults should aim to consume no more than 2,300 milligrams (mg) of sodium per day, with an ideal limit of no more than 1,500 mg per day for most adults—especially those with high blood pressure.
To minimize salt intake, it is advisable to avoid or limit these high-sodium foods:
- Canned soups and prepared meals which often contain significant amounts of salt as a preservative
- Processed snacks like chips, pretzels, and crackers
- Deli meats and cured meats like bacon and ham
- Cheeses, especially processed cheeses
- Pickled foods, which are preserved in salt to enhance their flavor
- Condiments, sauces, and dressings can have high sodium content; always read the labels
5. Citrus fruits
Oranges, lemons, and grapefruits are popular for their abundant vitamin C and essential nutrients.
Citrus fruits provide health benefits. However, they contain a substance called furanocoumarins that can affect the metabolism of certain drugs by specific enzymes in the liver and small intestine. As a result, the effectiveness of certain medications, including anticancer drugs, might not work as well.
This interaction can increase the risk of side effects and reduce the drug’s efficacy in controlling heart rhythm. Therefore, it is often recommended to limit or completely avoid citrus fruits and their juices while taking Flecainide.
Here is a list of citrus fruits that you may need to avoid or limit:
- Grapefruit and grapefruit juice
- Seville oranges (often used in marmalades)
- Pomelos
- Tangelos (a cross between tangerines and pomelos)
- Lemons and lemon juice
- Limes and lime juice
6. Alcohol Consumption
Alcohol use can affect greatly your cardiovascular system and is especially pertinent for those taking medications like Flecainide.
Drinking alcohol can speed up your heart rate and increase blood pressure. This can worsen heart rhythm issues. When your blood vessels are narrower, your heart has to work harder to pump blood throughout your body.
Also, alcohol can change how your liver processes certain medications, which can make them work less well and increase the chance of bad side effects.
It’s advisable to limit or abstain from alcoholic beverages like:
- Hard liquor, including whiskey, vodka, and rum
- Beer, which not only contains alcohol but also a substantial amount of carbohydrates and calories
- Wine, including both red and white varieties that contain alcohol and natural sugars
To manage their heart rhythm better while taking Flecainide, patients can reduce their alcohol consumption to minimize any potential interactions with other medications.
