FAITH REILLY: Interferon therapy is injectable therapy. There are three different kinds of interferon being sold to patients. And it alters the immune system, kind of turns it down so that your body is less likely to attack your myelin.
ANNOUNCER: Interferons can slow down disease progression, which makes all the difference for a person with MS.
FAITH REILLY: Interferon for me really seemed to change the direction my MS was heading in. The first year after my diagnosis my MS was quite active. I think I had five attacks in the first year. And within the first year of starting the interferon therapy, I had two attacks. And then since then, I maybe can count one or two total.
LISA PECK: I, for instance, noticed that my relapses were coming much less frequently, and when I was getting exacerbations or problems, they were less severe than they'd been in the prior three, four, five years. And so even though it wasn't something, you know, where you'd take a couple of aspirin and say, "My headache's gone," it does, over the course of a period of time, you start to notice that you're generally feeling better more frequently. So in my case, the real turning point was that I just really was starting to have more good days than bad days.
ANNOUNCER: Lisa is both a lawyer and professional cyclist and Faith, a nurse and mother. For each of them, interferon meant being more able to get on with their lives.
