I think it's difficult for family physicians to have so many different treatment modalities in their medical bag with the limited time they have. I know that we have some patients, especially who have MS, where it has been the miracle drug for them. They're no longer in wheelchairs and they can really get out and function, and that's wonderful.
It's tough. I'm not a doctor. The doctor's have to make that clinical decision, and we give them full authority to do that, because that's what they're good at.
