- Though this medication often gives great benefits to people with irregular heartbeat, it may rarely cause a serious new irregular heartbeat. Therefore, when starting treatment with this drug, your doctor may recommend that you stay in the hospital for proper monitoring. Flecainide should not be used to treat a certain type of irregular heartbeat (persistent atrial fibrillation/flutter). Talk with your doctor about the benefits and risks of taking this medication for your condition.
