Flecainide is a medication used to prevent and treat abnormally fast heart rates.[1] This includes ventricular and supraventricular tachycardias.[1] Its use is only recommended in those with dangerous arrhythmias or when significant symptoms cannot be managed with other treatments.[1] Its use does not decrease a person's risk of death.[1] It is taken by mouth or injection into a vein.[1][3]

Common side effects include dizziness, problems seeing, shortness of breath, chest pain, and tiredness.[1] Serious side effects may include cardiac arrest, arrhythmias, and heart failure.[1] It may be used in pregnancy, but has not been well studied in this population.[3][4] Use is not recommended in those with structural heart disease or ischemic heart disease.[1] Flecainide is a class Ic antiarrhythmic agent.[1] It works by decreasing the entry of sodium in heart cells, causing prolongation of the cardiac action potential.[1]

Flecainide was approved for medical use in the United States in 1985.[1] It is available as a generic medication.[3] In 2021, it was the 205th most commonly prescribed medication in the United States, with more than 2 million prescriptions.[5][6]
