Stopping Gilenya & Prolonged QT on ECG

Hi there, Has anyone had to stop taking Gilenya due to a prolonged QT interval on their ECG? My Gp who did the ECG didn’t seem too concerned but I mentioned it to my MS nurse and my MS consultant has asked me to stop it immediately! I’ve been ticking along on it nicely for eight years without a relapse so am feeling a bit anxious about what next! Would have no idea what to consider and am very concerned about the effects of coming off Gilenya. Has anyone had any experience of this? What medication have people moved to from Gilenya? What were the effects of coming off it. Thank you 😊
