Hi @abbie_dale I’ve been on gilenya for a couple of years and I’ve not suffered any side effects. When I started I had to take it in hospital wired up to a heart monitor as there is a very minuscule chance it could effect your heart rate, but at least you’re in the right place. For me there was no problems all I did was sit and read a book. I’m sure there’s nothing for you to worry about.
Take care, graham
