Tecfidera works by decreasing inflammation in the brain and has brain-protective actions. One of the ways MS is worsened is by inflammation caused by white cells damaging the nerves. Tecfidera keeps the inflammation down and the white cells out of the brain in multiple ways. It could also provide protection to the nerves. In addition to the four years of data on MS patients, the active ingredient in Tecfidera has been on the market for over 20 years for psoriasis, giving it more safety data. That said, the active ingredient has been linked to four cases of the brain infection, PML, in people with suppressed immune systems. None were taking Tecfidera.
