Gilenia is a treatment used for multiple sclerosis. It comes in pill-form and should be taken once a day. Although it does not cure MS, it can reduce the frequency of flare-ups. Gilenya is able to keep white blood cells in the lymph nodes, which results in a reduction of damage to the nerve cells. The cost of this treatment has not yet been released. A spokesperson for the company which makes the treatment has said that it will cost roughly $4000 per month.
