What is Gilenya?
Gilenya (fingolimod) is an immunosuppressant. It works by keeping immune cells trapped in your lymph nodes so they can't reach the central nervous system (brain and spinal cord).
Gilenya is used to treat relapsing multiple sclerosis (MS) in adults.
Gilenya will not cure MS, it will only decrease the frequency of relapse symptoms.
You should not use Gilenya if you have certain serious heart conditions, especially severe heart failure, "AV block," sick sinus syndrome (unless you have a pacemaker), if you take certain heart rhythm medicines, or if you have recently had a heart attack, stroke, chest pain, or other serious heart problem.
Gilenya may cause a serious brain infection that can lead to disability or death. Call your doctor right away if you have any change in your mental state, decreased vision, weakness on one side of your body, or problems with speech or walking.
