Welcome to Tecfidera—an oral treatment for relapsing multiple sclerosis

With Tecfidera, now is a good time to take on relapsing MS. That's because Tecfidera is an oral MS medication that defends against relapsing MS in many different ways, like reducing relapses, delaying progression of physical disability, and slowing the development of brain lesions. The safety and side effects of Tecfidera were documented in clinical studies.
