Any decision to switch from your current DMT to a different drug should be made in close consultation with your MS neurologist and care team. First, consider why switching might be beneficial in your situation. Some important reasons to switch are:

• evidence of MS disease worsening
• an adverse event from your current treatment
• a co-existing disease that complicates your disease management
• pregnancy or breastfeeding.

The more you understand your options, the better you can participate in informed, shared decisions about your ongoing treatment.

The grid below provides a quick way to identify the information relevant to your situation. The cell colours should help you to decide which options to explore.
