Sir,

Fingolimod is a structural analogue of sphingosine-1-phosphate approved as the first oral agent for the treatment of relapsing remitting multiple sclerosis. Apart from its effects on the immune system, fingolimod is known to have a negative chronotropic effect upon first dose intake. Little is known, however, about the longer term potential effects of fingolimod on ventricular rhythm. We document an increase in ventricular premature complexes (VPCs) in a patient on fingolimod who experienced three unexplained syncopes while on treatment. VPC frequency decreased significantly and no further syncopes occurred after stopping fingolimod. This suggests that, in predisposed patients, fingolimod might potentiate the occurrence of ventricular arrhythmia.

A 49-year-old male patient with relapsing–remitting multiple sclerosis was included in a 4-month phase 3b trial, involving fingolimod [ 1]. The patient provided written informed consent both for trial inclusion and this case report. At...
