Real-life data on switching medication 

While the increasing number of highly effective immunotherapies for multiple sclerosis has improved disease control, no disease modifying therapy (DMT) is entirely effective in halting disease activity. Switching DMT should therefore be considered in cases of breakthrough disease or an inadequate response to therapy, intolerability or specific side effects, adverse events, family planning, compliance issues, psychosocial reasons, and economic reasons. The aging MS population also raises the need for de-escalation of DMT, emphasizing the importance of the risks and benefits of such a switch which should be considered on a case-by-case basis. Real-life data can contribute with evidence on predictors of treatment response, guide the selection of the most appropriate DMT for individual patients, and inform treatment decisions when switching DMTs.
