New MS Drug: Q&A

How Does Tecfidera Compare With Other MS Drugs?

Why are these medicines only approved for relapsing MS and not for progressive MS?

Giesser: Most people who have MS have this relapsing-remitting form.

We don't have a good handle yet on all of the mechanisms that produce damage in progressive MS. It is much less understood.

Some of these newer medicines appear to have properties that may make them effective for progressive MS. In fact, they are being tested.

Why might my doctor decide to keep me on the medicine I'm taking and not switch me to the new medicines?

Giesser: If your doctor thinks your current medication is working, meaning that you are not having relapses and/or not having changes on your MRI, then he or she may say, 'Your medicine seems to be working.' If it ain't broke, don't fix it type thing.

Some doctors are pretty conservative. They may want to wait a little bit to see how the [new] medicines behave.
