When multiple sclerosis (MS) is not responding well to treatment, switching to a different disease-modifying therapy (DMT) should be discussed. Switching among established DMTs is common, but a number of newer DMTs that act on the body in a different way are now available. There is evidence that some of these have superior efficacy to established DMTs. People whose MS is poorly controlled by their current treatment may benefit from switching to one of these newer DMTs.
The articles in this section discuss switching to a different DMT.
