I don't think they have much of a clue. I was really reluctant to go on any DMD in the first place because I didn't think enough was known about MS or the immune system.
I still feel that way but have climbed on the Avonex bandwagon and now on the Copaxone bandwagon, just bouncing along for the ride. If it makes the docs happy for me to be taking one of these injectables and if it isn't doing me any serious harm
that I know of, I'll take my chances and shoot up whatever it is.
"Harm that I know of"--that's one problem, isn't it? So many new drugs that look perfectly wonderful at first have turned out to cause some ghastly type of cancer many decades later, and these drugs haven't been around long enough. But that's just one of my nagging doubts about taking a DMD. I try to keep it on a back burner.
