Last Updated on 1 year by Francis

Flecainide is a medication prescribed to treat certain types of heart rhythm disturbances. While it can provide relief from fast and irregular heartbeats, it may also come with some long-term side effects. In this article, we will discuss what the long-term side effects of flecainide are, and how they can be managed. By understanding the potential risks associated with this medication, you can make an informed decision about whether or not it is right for you.

Overview of Flecainide Side Effects

Flecainide is a medication commonly used to treat irregular heartbeats. It is used to reduce the risk of stroke and heart attack in people with certain types of heart rhythm disorders. The medication is generally considered safe, but there are some potential long-term side effects that should be considered. It is important to understand the risks associated with taking flecainide before taking it.

Cardiovascular Effects

The most common long-term side effect of taking flecainide is an increased risk of developing cardiovascular disease. This includes an increased risk of stroke, heart attack, and other cardiovascular problems. This is because flecainide can weaken the heart muscle and cause the heart to beat slower than normal. This can lead to an increased risk of developing serious cardiovascular complications.

Heart Failure

One of the potential long-term side effects of flecainide is an increased risk of heart failure. This is because flecainide can cause the heart to beat slower than normal, which can lead to decreased blood flow to the heart. This can result in a weakened heart muscle and an increased risk of heart failure.

Arrhythmias

Another potential long-term side effect of flecainide is an increased risk of developing arrhythmias. Arrhythmias are abnormal heart rhythms that can cause dizziness, chest pain, and shortness of breath. Flecainide can cause the heart to beat too slowly or too quickly, which can lead to arrhythmias.

Gastrointestinal Effects

Another potential long-term side effect of flecainide is an increased risk of gastrointestinal problems. This includes an increased risk of nausea, vomiting, constipation, and abdominal pain. People taking flecainide may also experience a decrease in appetite. These side effects can be managed with proper diet and nutrition.

Liver Damage

Long-term use of flecainide can also lead to liver damage. This is because flecainide is metabolized by the liver, and long-term use can lead to an accumulation of toxic metabolites in the liver. This can lead to liver damage and other serious complications.

Kidney Damage

Long-term use of flecainide can also lead to kidney damage. This is because flecainide is eliminated from the body by the kidneys, and long-term use can lead to an accumulation of toxic metabolites in the kidneys. This can lead to kidney damage and other serious complications.

Neurological Effects

Long-term use of flecainide can also lead to neurological side effects. This includes an increased risk of confusion, dizziness, and difficulty concentrating. These side effects can be managed with proper medical care and monitoring.

Seizures

Long-term use of flecainide can also lead to an increased risk of seizures. This is because flecainide can cause the brain to become overly excited, which can lead to seizures. It is important to seek medical attention if any of these symptoms occur.

Memory Loss

Long-term use of flecainide can also lead to memory loss. This is because flecainide can cause the brain to become overly excited, which can lead to memory loss. It is important to seek medical attention if any of these symptoms occur.

Other Potential Side Effects

Long-term use of flecainide can also lead to other side effects. This includes an increased risk of depression, anxiety, and fatigue. These side effects can be managed with proper medical care and monitoring.

Weight Gain

Long-term use of flecainide can also lead to weight gain. This is because flecainide can cause the body to become overly sensitive to insulin, which can lead to an increase in appetite and weight gain. It is important to speak with a doctor if any of these symptoms occur.

Bone Loss

Long-term use of flecainide can also lead to bone loss. This is because flecainide can cause the body to become overly sensitive to calcium, which can lead to decreased bone density and an increased risk of fractures. It is important to speak with a doctor if any of these symptoms occur.
