Hair loss is extreme and just started the past few months. was taking gilenya (fingolimod) for a year for ms. i am low in my vitamin d. could this be serious?

Thyroid: Be sure to check your thyroid, especially if you also have cold intolerance or weight gain. Multiple sclerosis and hypothyroidism are both autoimmune disorders.

Several issues: First, get your vitamin d into an appropriate range, especially by supplementing 5-10, 000 units daily, as higher levels decrease relapses, and MRI lesions. Secondly, Gilenya (fingolimod) does not cause hair loss, but Aubagio does. You may possess a co-morbidity, such as b-12 deficiency or thyroid issues, or even scalp problems. Should not go off your gilenya, (fingolimod) as you could have significant ms rebound.
