flecainide
Summary
Flecainide is used to treat heart rhythm disorders, which are problems with the heart's electrical system. It helps manage conditions like atrial fibrillation, which is an irregular and often rapid heart rate, and ventricular tachycardia, which is a fast heart rate that starts in the heart's lower chambers.
Flecainide works by stabilizing the heart's electrical activity, which helps maintain a regular heart rhythm. It blocks certain electrical signals in the heart, which can prevent irregular heartbeats and reduce symptoms like palpitations, which are feelings of having a fast-beating, fluttering, or pounding heart.
The usual starting dose of Flecainide for adults is 50 mg every 12 hours. Your doctor may adjust the dose based on your response. The maximum recommended dose is 400 mg per day. Flecainide is taken orally, which means by mouth, and should be swallowed whole with or without food.
Common side effects of Flecainide include dizziness, which is a feeling of being unsteady, headache, which is pain in the head, and nausea, which is feeling sick to the stomach. These effects are not experienced by everyone and can vary in intensity.
Flecainide should not be used in people with structural heart disease, which refers to physical problems with the heart's structure, or a history of heart attack. It can cause serious heart rhythm problems and requires careful monitoring by a doctor. Always follow your doctor's instructions and report any unusual symptoms immediately.
