Indicated for: cardiac arrhythmias
Substance: flecainide (antiarrhythmic)
ATC: C01BC04 (Cardiovascular system | Antiarrhythmics, class I and III | Antiarrhythmics, class Ic)
Flecainide is a medication used to treat certain types of heart rhythm disorders, known as arrhythmias. This medicine helps restore the normal rhythm of the heart and prevents irregular or excessively fast heartbeats, which can be dangerous to your health. Flecainide is usually prescribed to patients who have experienced episodes of atrial fibrillation, ventricular tachycardia, or other supraventricular arrhythmias.
Flecainide is typically taken orally in tablet form, with the dose determined by the doctor based on each patient's needs. It is important to follow the treatment exactly as prescribed, without changing the dose or stopping the medication without your doctor's approval, as this can worsen symptoms or cause complications.
Side effects of flecainide may include dizziness, fatigue, blurred vision, palpitations, or a sensation of irregular heartbeats. In rare cases, more serious reactions can occur, such as worsening arrhythmias or severe allergic reactions. If you experience unusual or severe symptoms, it is important to contact your doctor immediately.
Flecainide is an effective medication for controlling arrhythmias, but it requires careful monitoring by the medical team. During treatment, periodic tests and electrocardiograms may be needed to check the effectiveness and safety of the therapy. Be sure to inform your doctor about any other medications or supplements you are taking to avoid unwanted interactions.
