Fingolimod is the first oral disease-modifying therapy approved for multiple sclerosis (MS). The risks associated with the use of fingolimod include cardiovascular adverse events (AEs). First-dose observation (FDO) is required for all patients for at least 6 hours. We describe FDO data and long-term cardiac tolerability in a cohort of fingolimod-treated relapsing MS patients. Two hundred and twelve patients started fingolimod 0.5mg once daily. Before the first administration, all subjects had an electrocardiogram (ECG) with cardiologist interpretation. Following administration they were monitored for 6 hours and underwent a cardiac monitoring every 3 months. In this cohort, there was a heart rate reduction at the VI hour of 9.6±8 beats per minute (P<.001). Fifty-four individuals (25.5%) presented an abnormal ECG during the 6 hours. We experienced 1 case (0.22%) of symptomatic second-degree atrioventricular block. The mean follow-up period was 1.5±0.7 years. During this period, 1 patient showed atrial fibrillation that needed to be treated. We also observed 5 cases of persistent increase in blood pressure. This postmarketing study shows that fingolimod is well tolerated and tha tcardiologic AEs are generally self-limited in the long term.
